I am doing a complete teardown and rebuild of a Husqvarna 450 chainsaw. Although I did not do the initial disassembly I see some evidence that the clutch side crank bearing has begun to spin in its bore and therefore the clutch side crank seal is destroyed. I am wondering if there is a good method to ensure the crank bearings cannot rotate or have any slop once this is reassembled. I went ahead and used a fine chisel and knurled the surface. Any other tips, like loctite or any kind of spline cement?
Also if you look at the photo of the crankcase I believe there is a hairline fracture crack near the upper left cylinder bolt hole as reflected in the photo.
