Honda Acty Kei Trucks: Understanding the Safety Aspects Before You Buy

SHOP KEI TRUCKS FOR SALE AT OIWA.CO - CLICK PHOTOWhen considering the purchase of a Honda Acty, a popular Japanese Kei truck, it's crucial to understand its safety features, or lack thereof, in comparison to modern vehicles. As an experienced driving and racing instructor at Summit Point Raceway and with significant experience at Bill Scott Racing (BSR) and NASA, I've seen firsthand the impact that safety features can have on vehicle performance.
It's important to note that the Honda Acty, both in truck and van models, falls short of modern safety standards. One of the most significant concerns is the absence of a substantial crash structure between the driver and oncoming vehicles. This, coupled with the lack of airbags, means that an accident which might be non-fatal in a modern airbag-equipped vehicle could lead to serious injury or even fatality in an Acty.
Another key safety feature missing in the Acty is the anti-skid brake system (ABS). In high-stress situations where a panic stop is required, the Acty's lack of ABS can result in all four tires skidding, leading to a loss of steering control and an increased stopping distance. My experience with both ABS-equipped and non-ABS vehicles in professional racing contexts has highlighted the crucial role ABS plays in maintaining control and minimizing stopping distances.
Given its small size, low weight, and absence of modern safety features like airbags and ABS, the Acty should be approached with caution. Its safety profile is more akin to riding a motorcycle, where external risks are significantly higher. 
Despite these concerns, the Acty remains a vehicle I enjoy driving, but it's essential for potential buyers to be fully aware of these risks. Always prioritize safety and ensure you're prepared for the Acty's unique driving experience.

Navigating the Registration Process for Honda Acty Kei Trucks: Key Insights for Buyers

SHOP KEI TRUCKS FOR SALE AT OIWA.CO - CLICK PHOTOUnderstanding the intricacies of registration is paramount when considering the purchase of a Honda Acty, a renowned Japanese Kei truck. The process can be complex, and buyers must approach it with caution. Here at OIWA, we've gathered crucial insights to guide you through the registration labyrinth, ensuring you make an informed decision.
First and foremost, it's essential to treat any unregistered Acty as strictly for off-road use, unless it's freshly imported with complete and verifiable paperwork. The reason is simple yet significant: if a seller could legally register the vehicle, they would have already done so to fetch a higher selling price. A registered Acty can command up to double the price of one limited to off-road use. Therefore, if a seller claims the vehicle is registrable, insist on them completing the registration before finalizing your purchase.
The registration process for a Honda Acty involves multiple documents from Japan, several of which require professional translation into English by a certified translation service. Additionally, certain U.S. states, often referred to as 'blue states', have regulations that may prohibit the registration of Acty trucks for street use. This makes it crucial to consult with your local Department of Motor Vehicles (DMV) prior to making a purchase decision.
A unique challenge with the Acty is its shorter-than-average Vehicle Identification Number (VIN), which can sometimes lead to registration denials. Many prospective buyers have faced setbacks underestimating the complexity of this process. To avoid such pitfalls, we strongly recommend opting for an Acty that's already registered and comes with license plates.
For those considering direct importation from Japan, engaging a professional import broker is a wise move. These experts can manage the vehicle's arrival at the port and handle all necessary paperwork for registration, simplifying the process for you.
However, if your intention is to use the Acty solely as an off-road vehicle on private property, negotiating a significant discount – around 50% less than a road-legal, registered Acty – is advisable.
In conclusion, while the allure of owning a Honda Acty is undeniable, navigating the registration process requires diligence and informed decision-making. At OIWA, we're committed to guiding you through these challenges, ensuring a smooth and transparent buying experience.

Mastering Maintenance: Essential Oil Change Tips for Your Honda Acty Kei Truck

Embarking on the essential task of changing the oil in your Honda Acty Kei truck ensures longevity and consistent performance. It's a straightforward process best undertaken after a drive when the engine, transmission, and differential oils are warmed up, optimizing flow and removal of impurities.
Optimal Engine Health with Regular Oil Changes
For the engine, 10w30 grade oil is ideal, with a capacity of 3 quarts (2.9 liters) if you're including a filter change, or 2.8 quarts (2.7 liters) without. In the frigid embrace of temperatures below -22 degrees Fahrenheit (-30 degrees Celsius), switch to 5w30 to maintain viscosity. The manufacturer recommends an oil change every 10,000km (6,250 miles) or biannually, but with a seasoned odometer surpassing 100,000km, a high-mileage synthetic blend like Castrol's offers the protective care your Acty deserves.
Finding the Right Fit: Oil Filters and Filling
When selecting an oil filter, the compact size is crucial for a snug fit. Compatible options akin to Honda's original part include the NAPA 1334 or its premium counterpart, the NAPA Gold 1358, as well as the Fram PH9688 and Mobile 1 M1-108A, all sharing the M20x1.5 thread size. [ Purchase Honda Acty Oil Filters At Oiwa Garage ] Before installation, a touch of clean oil on the filter gasket and threads ensures a perfect seal. While taller filters like the Bosch 3323 might tempt with their increased capacity, their vulnerability to road debris makes them a risky choice.
Locating the Essentials: Dipstick and Coolant Reservoir
Nestled behind the tire, the dipstick awaits your inspection, a simple check ensuring your Acty's engine oil level remains optimal. Although the coolant reservoir is out for a cleanse, its usual spot is adjacent to the battery box, a gentle reminder of the importance of coolant health in engine temperature regulation. This is crucial information to share with anyone borrowing your trusty Kei truck, alongside the location of the fuel and oil fills, to prevent any mix-ups that could lead to an unwelcome crankcase surprise.
The act of changing your Honda Acty's oil is more than a mere maintenance chore; it's a ritual that keeps the heart of your truck beating strong. With the right knowledge and tools, you ensure that every journey, no matter how rugged, is met with unwavering reliability.

For those who tread off the beaten path, the Sun F All 22x7x12 off-road tires are compatible with the Acty's standard wheels and can be found on Amazon at $61 each, with shipping included.
For the ultimate off-road traction, the Carlisle Tru Power and Farm Specialist R1 23x6x12 tires are unbeatable. Available for around $65 each on Amazon, they're a favorite among off-road enthusiasts.
Whatever your preference or driving needs, OIWA has you covered with a range of tire options that will keep your Honda Acty performing at its best, whether you're navigating city streets or rural trails.

Upgrading Your Honda Acty's Wheels: A Strategic Guide for Enhanced Performance

For Honda Acty kei truck owners, the wheels are a fundamental aspect that can significantly influence your truck's aesthetics and functionality. 
Typically, the Acty comes equipped with 12x3.5" wheels, boasting a 4x100 lug pattern, or the slightly larger 13x4" variant, both featuring a precise 56.1mm center bore hole for a snug hub fit.
The factory wheels offer a generous 100mm (3.9") backspacing, ensuring approximately 1" clearance from the coil springs when paired with standard tires, providing a balanced and secure ride.
For those looking to customize their Acty, wheel adapters are a game-changer. They open up a new world of possibilities, allowing the fitment of more ubiquitous 4x114.3 wheels. For instance,
 a set of four 1" (25mm) thick Wheel Adapter Spacers can be procured from Amazon for about $58, converting a 4x100 to a 4x114.3 pattern with M12x1.5 lugs. These adapters effectively add an inch to both positive offset and backspacing.
When it comes to upsizing, with a 1" 4x114.3 adapter in place, owners can fit bold 14x7 +13 offset Fuel Maverik wheels wrapped in 23x9.5x14 inch tires for an assertive stance. Moreover, 14x6 +30 offset wheels with 175/65/14 tires offer a no-lift, no-rubbing solution, maintaining the truck's low profile while enhancing its road presence.
Lastly, securing your new wheels with the right lug nuts is paramount. For the Acty, M12x1.5 lug nuts are the perfect match, readily available on Amazon.
At OIWA, we understand that every detail counts. That's why we're committed to providing our customers with the insights they need to make informed decisions about their vehicle upgrades. Whether you're looking to enhance your Honda Acty's performance or its street appeal, we've got the expertise to guide you every step of the way.

Essential Guide to Honda Acty Brake Maintenance for Enhanced Safety

Maintaining the brake system in your Honda Acty kei truck is crucial for ensuring your vehicle's safety and performance. Front brake calipers and disks are among the components that may require attention during the vehicle's lifespan. 
When it's time to replace the front brake pads, start by locating the 12mm caliper release bolt, which, once removed, allows the caliper to swing upward. This action will enable you to slide out the old pads easily.
Before you can fit the new, thicker brake pads, it's necessary to retract the brake piston. This can be done using a C-clamp or a specialized brake piston compressor tool, which will create enough space for the caliper to fit over the new pads. It's important to note that pushing back the brake piston may cause the brake fluid reservoir to overfill. 
To prevent any overflow, it's wise to check and potentially remove some brake fluid from the reservoir after compressing each piston, especially after completing the first one.
If you're also looking to remove the brake disk, the process involves detaching the caliper and its bracket by unscrewing the two hefty 17mm bolts that secure the bracket to the knuckle. 
The brake disk itself is fastened with two Phillips head screws, which can be swiftly removed with an impact driver. Due to the screws' soft metal composition, if they prove stubborn, drilling them out is a viable option to free the disk. Sometimes, a gentle tap with a rubber mallet may be necessary to loosen and remove the disks.
At OIWA, we're dedicated to empowering Honda Acty owners with the knowledge to perform routine maintenance safely and effectively. By following this guide, you can ensure your Acty's brakes are in top condition, keeping you and your cargo secure on every journey.

Maximizing Your Honda Acty's Potential: The Pros and Cons of a 2-Inch Lift Kit

Elevating your Honda Acty with a 2-inch lift kit can offer a fresh look and the capability to fit larger wheels and tires, but it's not a decision to take lightly. Priced around $200 on eBay, the lift kit can indeed give your kei truck a more robust stance. 
However, be aware that such modifications can raise the vehicle's center of gravity, which may increase the risk of rollovers. Furthermore, a lifted Acty can exert additional stress on the CV joints, potentially leading to accelerated wear and tear.
For those set on installing a lift kit, the process involves some careful steps:
  1. Begin by removing the front seats to access the strut tower nuts.
  2. Jack up the Acty's front end at the center brace to lift both wheels simultaneously, then secure with jack stands.
  3. Proceed to remove one wheel at a time.
  4. Detach the brake line bracket from the strut to allow for movement during suspension work.
  5. Unfasten the three strut top hat nuts located beneath the seats (watch for insulation or carpet in an Acty van that might cover these).
  6. Support the wheel hub with tie-wraps or a bungee cord to prevent straining the brake line while you handle the strut.
  7. Install the lift spacers and then reassemble the struts, making sure the spacer studs align correctly before tightening the top hat nuts.
  8. Reattach the brake line bracket to the strut – this step is crucial, so double-check it.
  9. Repeat the process for the other side, ensuring all components are secure before reattaching the wheels.
For the rear lift:
  1. Jack up the rear of the Acty, ensuring the tires are just touching the ground to relieve tension on the leaf springs.
  2. Remove and replace the leaf spring support brackets with the extended versions provided in the kit.
Keep in mind that a front-end alignment will be necessary post-installation to correct the toe-in and prevent uneven tire wear, as the rear wheels are not adjustable.
While a 3-inch lift kit is on the market, it requires more extensive modifications and isn't recommended for the casual user. If you're considering a lift for your Honda Acty, approach it with caution, understanding the changes in dynamics it brings to your vehicle.
For those who prefer their Acty closer to the ground, OIWA offers a wide selection of original-spec parts and accessories to maintain and enhance your vehicle's performance without altering its factory design.

Revitalizing Your Honda Acty: Front Spring Upgrade Guide

When the rough terrain becomes a challenge for your Honda Acty, it may be time to consider refreshing your mini truck's suspension with new front springs. 
Here's your step-by-step guide to revitalizing your Acty's bounce, ensuring it handles those bumps with ease.
First, recognize that worn-out struts can lead to the front end bottoming out. While original Honda replacements can be costly, sourced directly from Japan, there are more economical options. 
Aftermarket solutions, like GAZ coilover struts, offer a premium but pricey alternative. 
For those seeking a budget-friendly fix, replacing the front springs is your best bet. Opt for springs that are 10 inches long, 2.5 inches in diameter, and a weight class that suits your needs—275 lbs is a common choice. 
Now, the task at hand—installation. You'll need a spring compressor, so ensure you have one on hand. Begin by removing the front seats to access the strut tower nuts. Jack up the Acty's front using the central brace, lifting both wheels off the ground. Secure with jack stands.
After wheel removal, apply penetrating oil to the sway bar end link nut and other related components. Disconnect the sway bar end link to ease spring swapping—this is crucial as it reduces tension. Also, detach the brake line bracket from the strut for better suspension mobility.
If you're also replacing the struts, loosen the clamp bolt at the strut's base. Otherwise, focus on the three strut top hat nuts beneath the seats. Be ready to catch the strut when the last nut is free, but leave the central strut shaft nut for now.
With the strut removed, you can take off the top hat and spring. Remember the assembly order, and consider using a ViceGrip with duct tape to avoid damaging the strut shaft. Replace the old spring with the new one, compress it with the spring compressor, and reassemble the strut.
Once the strut is back in place, reattach the brake line bracket and sway bar end link, ensuring all parts are secure. Repeat on the other side, then finish up by reinstalling the wheels and taking your Acty for a test drive.
An important note: if your Acty's ride height changes significantly after the spring upgrade, you may need a front-end alignment to ensure proper toe-in and prevent uneven tire wear.
By following these steps, you can ensure your Honda Acty remains a reliable and sturdy partner for all your hauling needs. 
And remember, for all your mini truck parts and expertise, OIWA is here to help you navigate maintenance and upgrades with ease.

Mastering Rear Brake Drum and Wheel Bearing Maintenance on Honda Acty Kei Trucks

Maintaining the rear brake drum and wheel bearings of your Honda Acty is crucial for optimal performance and safety. For those keen on DIY maintenance, here's a comprehensive guide on how to tackle this task effectively, highlighting the use of Timken 6206-2RS double rubber sealed wheel bearings, ideal for both the truck and van models of the Acty.
Firstly, begin by removing the rear wheel to access the axle nut cover at the center of the brake drum. A pro tip: loosening the axle nut is more manageable with the tire on the ground, so you may want to temporarily put the wheel back on and lower the Acty. Next, remove the axle nut cotter key. For this task, arm yourself with a substantial, long breaker bar to loosen the axle nut, and remember, you'll also need a hefty torque wrench for reinstallation.
Once the rear wheel is off again, employ a puller – such as the Maddox $90 Slide Hammer & Puller Set – to detach the brake drum. This set is incredibly versatile, offering both pullers and a slide hammer to simplify the process. With the axle nut and cotter pin removed, attach the puller to the rear hub/drum. As you tighten the center shaft, it will push against the drive shaft, effortlessly pulling the hub off.
Accessing the brake shoes and wheel bearings becomes straightforward with the hub removed. Using the bearing puller claw attached to the slide hammer shaft, grip the wheel bearing and use forceful sliding motions to extract the bearing. This step might require a bit of elbow grease, but persistence pays off.
Once the old bearing is out, it's time to install the new one. We recommend the high-quality Timken 6206-2RS wheel bearings, which are pre-greased and fit both the front and rear of the Acty. Use the bearing pusher, ensuring it contacts the outer race of the bearing, to smoothly slide the new bearing into place.
Remember, applying pressure on the inner race can damage the new bearing.
For those who prefer an alternative method, a two-jaw puller grabbing two lug nuts can also be employed to remove the brake drum, especially after the large axle nut has been taken off.
After reassembling, it’s crucial to torque the axle nut to the precise specification of 20kg/m or 145 lb-ft and reinstall the cotter pin. This attention to detail ensures your Acty’s wheel bearings and rear brake drum are maintained to the highest standard, enhancing both the longevity and safety of your vehicle.
In summary, maintaining your Honda Acty’s rear brake drum and wheel bearings is a task within reach for the dedicated DIY enthusiast. With the right tools and a bit of know-how, you can ensure your Acty remains in top condition, ready for any adventure or task it faces.

Expert Guide to Brake Fluid Maintenance in Your Honda Acty Kei Truck

Brake Fluid Maintenance For Your Honda Acty Kei TruckEdit Image
Maintaining the brake fluid in your Honda Acty Kei Truck is essential for ensuring its safety and reliability. Conveniently located behind a pop-off panel on the dashboard's right side, the brake master cylinder is easily accessible. Open the driver's door to find the panel on the dashboard's side.
Honda Acty's manufacturer recommends using either DOT 3 or 4 brake fluid, but I lean towards DOT 4 for its higher boiling point and better performance. The key to an effective brake fluid change lies in the bleed order: start with the right rear, then the left rear, followed by the right front, and finally, the left front.
For those planning a complete fluid flush, use a mechanic's syringe to remove as much old fluid from the reservoir as possible. Refill it with fresh brake fluid before commencing the bleeding process. It's crucial to avoid letting the reservoir run too low during bleeding to prevent air from entering the brake system.
To bleed the brakes, remove the rubber cover from the brake bleed nipple and attach a clear plastic hose to it, directing the other end into an empty bottle. 
Have an assistant apply pressure to the brake pedal while you open the brake bleed nipple. 
This action will send the brake fluid through the tube, with the pedal reaching the floor. 
Keep the pedal down until you've closed the nipple. Then instruct your assistant to release and reapply pressure on the pedal as you open the nipple once more. Repeat this process until fresh, clean brake fluid emerges from the nipple. Regularly check and top up the brake fluid reservoir during this process to prevent air intake.
Once you observe new, clear fluid exiting the bleeder, secure the nipple, replace the rubber cover, and proceed to the next wheel in the sequence.
Remember, the brake master cylinder and its reservoir are just behind the access panel, which can be easily removed with a gentle pull. Regular brake fluid maintenance is not just about performance; it's about ensuring the safety of every journey in your Honda Acty Kei Truck. Stay tuned to OIWA for more insightful maintenance tips and tricks for your beloved Kei truck.
