Re-installing NAA Flywheel

Ramrod

This is what I did. I turned the engine over until I felt compression with my finger at the # 1 spark plug hole. This should be TDC. I alligned the timing marks on the flywheel with the notch in the engine plate timing hole. The flywheel went on like a charm. Torqued it down to 85 ft #'s. I got the engine reinstalled on the tractor.

I'm anxious to see if all my repairs and engine overhaul were sucessful. We will see. HTH. Rick H. Ga.

Thanks Guys!

Are there any marks, rust patterns, discoloration patterns, etc, on the back side of the flywheel that might line up?

One book I have says the flywheel 'run-out' should not be more than 0.004". If it is, then rotate to a new position and try again. If run-out is more than that in all positions then the face should be machined down, but not to get the flywheel less than 0.885" thick (for an N tractor).

My N-Ford MPC shows the NAA crankshaft flywheel retainer to have 6-holes, 2-dowels and 4-bolts.

And I'll just bettcha that iff'n you look real closely, you'll find 'nuther set of timing marks 180* around the flywheel from the 1st set of timing marks. So it doesn't really matter which set of index dowels you use.

Oh yes, definately white paint mark your timing marks BEFORE you install the flywheel 'cuz its eazier then..... ..Dell

BTW..... .the FRONT crankshaft gear is half-moon keyed and the camshaft gear is 4-bolts (off-set) and indexed marked to the crankshaft gear index
