m38 crankshaft

spe · Post by **spe** » Thu Oct 18, 2012 5:34 pm

my m38 has the counter weights bolted and welded, as it should be. My question is is a f head the same/interchangable with the L 134?

i need a replacement crank, mine is not servicable.

Is the crank really damaged or just scored where the piston rods attach?

I ask as I had a L161 Engine for a Willys Wagon and it was scored where the rod bearings had worn and locked the motor up... I took it to a machine shop and they had it welded (adding material) and then machined it back to factory specs...

Just a thought...

Hope this helps...

Yes, The M38 and the M38A1 use the same crank, WO# 646316 bare or 647078 with the set of flywheel bolts & nuts. Keep in mind there both tapered dowell and straight dowell versions of these cranks using the same part number.
