Grandson watched me change some PTO bearings last week. He grabbed a junk crank, said he was gunna take it apart and pulled the end bearings.

Today, I hear some commotion, peak out of the lathe room and hes got the end wheels off, and hanging on the press working the center section. Lol

Going back in the sled tomorrow and hope to find enough snow on the hill tomorrow to have it dialed in enough for the hillclimbs this weekend.

I have a 24' Polaris 9R motor for sale. Edit, pic is of the actual motor now.
Motor had mid 300s for miles and locked up a center bearing on the crank. Crank has been rebuilt with all new bearings, trued and welded for added durability. Crank is straight and rolls perfect 0s. I gave the cylinders a fresh honing.
$3500 shipped anywhere in the continental US and Alaska. Can ship to Canada also but may cost slightly more.
More pics and videos of the crankshaft in the comments as it wouldn't let me load them with the main pic.

Some case work, some crank work and some port work. Getting closer on this 910 CFI big bore.
