Crank Ques

[corey2120]

ok i got my crank in today and i was putting on my cam gears and other stuff but i ran into a prob. is it suposed to be extremly hard to put on everything?? it seamed like the gear was to small and everything else i put on. i don;t kno if this is normal or not if you could help me out that would be great. the crank is a CB 76mm and CB straight cut gears and CB crank kit with racer spacer

Heat the gear up on a hot plate.
It'll go right on then.
Dots out!

Sometimes the spacer has to be warmed up too.

mine was a bitch to get on too!!!

i bought a brass hammer so i would not screw anything up......

one of my buddies said afterwards maybe i could have the cam gear machined down just a hair to get it to fit better!

[corey2120]

yeah i broke my cam gear and the crank kinda pissed i had to order all new stuff but what ever its only 179 bucks i am goin to try again with this if it doesn't go on easy i'll try to get it machined down

You have to heat the cam gear. I use a torch. It's made to be a press fit.

Don't machine anything.

This technique comes from the Tom Wilson book "How to Rebuild Your Volkswagen Air-Cooled Engine."

Put the gear and spacer in a small pan filled with some vegatable oil. You only need enough to cover the gear. Now heat the oil until it starts to show wispy smoke coming off the surface. The gear will now be hot enough and expanded enough to slip easily on the crank. You only get one shot at this - you need to work quickly because the gear cools quickly once it comes in contact with the cold crankshaft. Once you extract the gear from the hot oil you can handle it with a thick leather work glove.

I've used this technique several times and the gear will just drop into place if you work quickly. Good Luck!

if it cools can i just put it back in and heat it up again?
