In the future, once you get the crank out, you might want to both spray brake cleaner into all of the bearings and then blow them out out with compressed air. Then you test each bearing by free spinning it using either compressed air or your finger, and then you listen for how much rattle you get. Any rattle means the bearing is worn and may not have that much life left. Since replacing the 4 end bearings is relatively easy, unless they appear to be new, replace all 4 of them. As for the others, that requires a machine shop and a skilled technician to reassemble the crank and have zero run out. for a 2 cylinder engine, some minor wear in the interior bearings can be tolerated. But replacing the outer bearings is as good investment as you can make in your snowmobile. Also check to see whether you have any connecting rod bounce due to worn bearings. Any bounce then consider having a professional replace all of those bearings at the crank end and might as well have all the other bearings replaced as well. Buying a fully re-manufactured crank is usually the best way to go, as people are trying to unload those old cranks that they put all kinds of time and money into.
thanks I have seen quite a few videos on doing this as I have to do mine it's nice to get different view points yours seems to be the most practicle and least destructive thanks
what is the part number for the PTO bearings? I have already torn the motor down and cant seem to find what bearings to get. Thx for the awesome videos on this build!
Yeah they are hard to source online. Here's the info I have for my 95 XLT. PTO bearing 5 (grooved with ring) : # 564-2572 PTO bearing 6 (last bearing on PTO side; same as the 4 middle bearings) : # 564-2573
@@MarshallBLewis thanks! I also have the 95 XLT. If it was not in such good condition I wouldnt have been looking for videos of a rebuild. Your video series on this engine are EXCELLENT!

Good video. Thanks for sticking it out in the cold there!
You bet. Glad it's helping you out
Great idea with the needle oiler!

Wish I had the room to keep my old T 650.
That's wut a dremel tool is for
