Oiwa Garage Tech Note
"Replace the rotor with the cap - they wear as a set. Line the new rotor onto the shaft flat so it seats fully before you refit the cap."
Frequently Asked Questions
Do I need to set timing after this?
No timing change is needed to swap the rotor itself; it presses onto the distributor shaft in one orientation.
Should the cap go on with it?
Yes, do the cap and rotor together for the best result.
How do I check the distributor rotor?
Pull the cap and inspect the rotor tip. A burned, pitted, or corroded tip causes weak spark and misfire - replace it, and fit a fresh cap with it.
