365 XT refresh questions

[dgeesaman]

I picked up a 365 XTorq used with a bad oiler. I took apart everything to clean it of oil dirt except for the main case and flywheel. (I also ground the transfer port baffles off, a la 372 conversion.) Piston and cyl is in decent shape but not perfect and I'll probably leave them as I'm trying to keep costs in check. In addition to the oil pump and drive gear, I'm changing all of the fuel / oil hoses and filters.

Would it be wise to split the case and change the crank bearings and seals while I'm in there? I was planning to leave it be but could be convinced otherwise. This saw was built in 2011.

I would probably change the bearings for piece of mind. The newer 365 and 372XT have the plastic ball spacers. I feel that the plastic spacers would get brittle over time.

I was told to run 32-1 are 40-1 to lube the new plastic retaning bearing cages and to not tune over 13,000 RPM because piston larger than older series ..
