Been a while since I gave everyone an update.
Logic says that if you get a new crankshaft, the old one has to come out.
I scored a crazy deal on a Tusk crankcase splitter and crank puller.
They arrived yesterday so I set to work.
The case came apart easier than expected.
The crankshaft is completely trashed. There’s about 1/16” vertical play in the big end bearing.
Because of the fretting where the bearing goes, I suspect the main bearings spun in the case and on the crank.
I ordered new OEM bearings and seals today. And picked up a hardware kit to replace some of the missing or mangled fasteners.
Frame is ready for blasting. Just need to get it there.
I’m thoroughly enjoying this process. My partner said that she expects I will build another bike :-)
