Tiger Update

Ever have several days of working on something where you feel like you are effectively sweeping the same pile of dirt around and around the floor? I've pissed away more time than I care to admit this week trying to sanely extract the primary side main bearing from the from both the case and crank without damaging anything. I won't bore you with details but it's been an ordeal. Well I was working on other stuff too I guess...

I finally got the bearing free of the case and tried several methods of removing it from the crank. I was pretty certain the spline end of the crank was galled based on how hosed the splined collar was that came of the funky primary drive shock absorber doohickey thing (English term). If you compare the piece to parts book diagram it looks like the retaining lip just snapped off.

I talked to Justin about it this morning and he basically said "Quit f-ing around and cut the damn thing off" (to be accurate he did recommend a pretty surgical method). You don't have to tell me twice.

I don't know how well you can see it in the photo but there's a pretty serious lip on the inbound set of the crank splines. That bearing would have never moved.

I've also spent gobs of time cleaning and detailing parts. If I had access to a media blaster it would go much faster but I'm still trying to save $$$ for parts. It's coming along slowly. Here's a tease.

I'm hoping to get the frame in for powdercoat this week. One of the parts I'm missing is the original tank mounting brackets. I considered making something but they carry a fair amount of weight (I think the tank is 4.5 gallons). The original pieces are quite beefy. I bought a front mount on eBay.

I'm kind of anxious to have a roller again.

Looks like you were successful in getting the bearing cut off without doing any further damage to the splined shaft.

I can't tell you how many times I have gotten to the point where I need someone like Justin to perform an intervention and kick me in the ass to get beyond some stupid sticking point...
