cylinder head 42b

[djbnsp]

replacing head after valve job, looking for info on torque spec,
valve clearance (cold) after assembly to start with. also any
tips on how or best way to set them.

Head bolts.......104 ft lbs.

Valves....... .020 hot, I always set them at .022, or .023 cold, Too loose is always better than too tight.

Roll flywheel till TDC on comp stroke left cyl (LH impulse mark on flywheel aligned with mark on case) do left cyl (flywheel side) roll over till right side is at TDC, and do right cyl. I think it is 180 degrees.

Hope this helps you.

You might want to search the forum under "lifter noise". That thread covers how to set valve clearance when the rockers or pushrod tips are worn and a feeler will give a false reading. Sounds like you've got a nice tractor there!
