Thanks everyone for the advice!
I found guy parting out a ‘01 TRX450ES for the front diff and prop shaft. I picked up a used final shaft from PowerSportsNation, it looks perfect! Next I’m going to source the timing chain, gasket maker, seal kit, crank bearings, etc. and make a plan for pulling and splitting the engine.
I’m excited to tackle this project. It’s pretty involved!
Did you verify that the used OEM parts you got were the right part numbers?
These old 350's are tanks when running, but they can be a PITA to get parts for because most people think they're all the same 86-up because they all pretty much look the same.
power sports nation is a better deal than ebay. '' sometimes'' you can get good used parts from ebay !.as for anything ele from amazon ?..lol..i stay far away from amazon..heck..anything thats important on atvs..i stay away from amazon !. china junk period !.
