9N RING JOB

As I was doing mine it was pretty obvious that there is not a whole lot of room in the crankcase. The crank has gotta be rotated around with the journals pretty close to vertical or you'll never get the connecting rod out—it hits on the bottom of the cylinder. Otherwise, actually getting the pistons out is not really that bigga job.

Of course there's always the usual things to check before taking the piston out the top—like the cylinder ridge. If there's much there you can have a time gettin the old pistons/rings out. Ridge reaming is suggested. Of course you're gonna hone the cylinders before putting in the new rings, right?

Don't fergit ta keep yer rod caps matched with the rod. And protect the crank journals by putting some tubing on the rod bolts before lettin em slide past the journal (3/8" vacuum hose works well). While you've got it open it wouldn't hurt to measure the journals as well. You just might want to stick in some new undersized rod bearings. You can get them in some very small undersizes before the big jump to having the crank resized.
