Engine Reassembly

Postby arlen » Tue Mar 23, 2021 12:24 pm

Well I finally have all the parts in hand to start reassembling the block.
What sequence of assembly do you prefer? Put the sleeves in, then the crank, or the crank first. What about the pistons/rods? Do you like to put them in before the crank?
I'm kind of assuming it's best to put the head on while its in the engine stand out of convenience. It would seem that the front cover/pulley could go on in the stand or on the tractor and not make much difference.
Also, the replacement clutch from Steiner's doesn't appear to have a way to thread bolts in to compress the springs for reassembly like the OEM one did. Any ideas there?

If it were me, I would probably do;

Sleeves first.
Crankshaft next.
Put the pistons in the bore third.
I would probably attach each rod / bearing / rod cap to the crank as I installed each piston rod assembly!

Sounds reasonable. Any advice on the clutch installation?

When I had the clutch out of the BN I sold for the pilot bushing replacement, I started each screw attaching the pressure plate into the flywheel, then progressively (little turn on each) worked my way around alternating from one side to the other until they were snug then torqued them last.

If for some reason your screws are too short to grab into the flywheel, you might have to start with some longer ones and draw the pressure plate up close, then replace those screws with the proper ones (one at a time)!

Thanks! and that cheesy plastic alignment "tool" that came with the clutch kit is to align the clutch to the pilot bushing?
