    Couple questions about this movt

    1. Reversing wheels.....are they serviceable? If so what is the correct oiling procedure?

    2. Date change wheel....should the top gear (with the spring) that is riveted to the lower gear be lubricated?

    I have reused the reversing wheels. They are usually very good constuction. I use diluted 9010. About 100:3 . Search on google for lubricating reverse wheel 9010 . Lubeta is a lube for reversing wheel but that is to heavy for Certina wheels. Found they stick together. 9010 and naptha wok great .
