G1 crank bearing stuck in the case
I just split the case on my G1. The crank bearing on the clutch side was growling pretty loud.
The bearing is still in the case as opposed to being on the crank. Rebuild manual says nothing about this bearing..?? Do I remove it inward or outward? Theres a snap ring on the outer side which would imply it goes outwards. Little help? |

Re: G1 crank bearing stuck in the case
It’s supposed to do that. And it gets installed in the case then the crank gets pulled in. Put the case on a single burner and monitor temp with heat gun then knock it inward

Re: G1 crank bearing stuck in the case
Don't press that out cold, do like Mike says and heat it up in a propane grill to about 250 degrees. That bearing will almost fall out. If you try to press it out you risk damaging the soft aluminum case.

Re: G1 crank bearing stuck in the case
Tossed it on my camping stove and ran up near 300 degrees. Came out pretty easy. New bearings are in the freezer tonight.

Re: G1 crank bearing stuck in the case
There you go. Do the same thing with the frozen bearings, pop them in the warm case, good to go. When you install the crank, stick that in the freezer too. You can warm the bearings up a little before you slide the crank in, but don't use direct heat. It's tricky, but I actually put the bearings and cases back in the grill and warmed them up just a little, then carefully slid the frozen crank in with some PB Blaster on it. I had to press it together, but not too much effort. It actually worked really well.

Re: G1 crank bearing stuck in the case
i think your backwards here. the flywheel /stator side is the threaded side with the male threads to hold the flywheel on. the clutch side is female threads. m16x 1.0 I think. Ill confirm with my clutch puller
