1996 Yamaha vmax 600 xt crank threads

I messed up my threads on the crank where the primary clutch bolts on to. Does anyone know what size threads and pitch. and where I could get a tap that would clean this up? Anything would help. Thanks . 1996 Yamaha vmax 600 xt Chad

check the bolt on the clutch and match it to a dye and then use the matching tap

good luck!!

It's a 1/2-20 SAE fine thread. Be very careful with the tap- the crank is VERY hard material and any thread damage will be harder to chase than a hole in mild steel. Use lots of oil and back off the tap frequently to clean the chips out.
