Hi Scott

While your waiting for some to walk out the shop and try some bolts to get the size and thread count to pulling the harmonic & pulley assembly. Take some time to carefully clean the threads in the pulley.

As many of these have a rubber cushion I would not use solvent or penetrating oil. I used a small spiral wire brush in a drill to clean the threads then chased it with tread tap.

Also be careful when reinstalling don't hammer on the crank hooks they will bend down and you will not be able to use the crank or the crank will not release when the engine starts. I made a tool for reinstalling the pulley that I will photograph (once my camera is repaired).

When you get the pulley assembly off you will probably find that their is a grove worn where it seals. There are Speedy Sleeves just for fixing this issue. Cheap $6.32 US NAPA Part # 600-2016.

See photo to confirm we are talking about same bolts and assembly.

Cheers Phil

PS- Just checked the pulley damper pulling thread - ones on mine are 3/8" x 16 thread.
