Crankshaft reinstallation in a 650 H1
I'm back to the re-building stage of my 650. Riddler set me up with a 2nd hand crank in good condition. Managed to get the old crank out with a bit of pounding and persuasion. Didn't mind pounding on the old one as I figure that bearing has served its time - and the crank was toast.
The second hand crank has the bearing in place, not really interested in replacing that bearing, seems to be in great shape. Given that the bearing is on the crank, is there an easy way to get the bearing/crankshaft back into the casing without too much heavy pounding? I'm going to heat the casing with a propane torch and I've got the crank in the freezer for overnight. Hoping that temperature difference is enough to make it fairly easy. Does anybody have any experience with this? Is this approach do-able? Any other suggestions?
The AC service manual suggests that if the bearing is pressed into the case, the inner race can be heated with propane and the crank should slide right in - but I'm not reassembling it that way.
PS. And extra thanks to Riddler for supplying the replacement crank - hope your own engine problems get resolved without too much grief.
