You can also get a remanufactured BRP crankshaft part# 421000076. I just bought one for $351.19, with a $200 core, which was promptly refunded the day they received my crank, shipping was either $10 or $20. Most dealers charge $389 to $438+ core. Yes, it is $76 more than the SBT, but it's 100% OEM, brand new SKF bearings, new crank seals, new rods, new large end rod bearings and a new oil pump drive, and a new woodruff key. It's pure sex in a box! Like I said it is more money, but it's all top quality OEM parts. The crazy thing is if you wanted to replace the counter balance, that's like $318, but you can have yours rebuilt if you want, just check the bearings and seals on that. And take notice if there is any oil PAST the two lip seals, there should be no oil that has traveled towards the flywheel end of the case, if so, time for a rebuild of that. And to the best of my knowledge, whether you have the non serviceable counter balance case or the later serviceable, there is no difference in the gaskets. These are some great engines to build, I'll be starting another of mine over the next few days.
On another note, once you tear down the bottom end, if that engine has ever been rebuilt and has a welded crank in it--you CANNOT exchange that for a BRP one, you'll be out the $200. In fact, most places that rebuild cranks will not accept a welded crank, not sure what SBT's policy is on exchanging a welded crank, you might want to find that out too. I'd hate to see you lose some core money
