how long does it need to be

 

I bought mine from True Value for $4. Its M16x2.0 pitch and 120mm long grade 8(approx. 1inch longer). Works great! Dont forget about a grade 8 washer too.

 

did u use the longer one to take the pulley off too

 

I cut my old bolt between the shoulder and threads then added 3/4 of an inch of solid mild steel rod rod same diameter as smooth section. I then gouged and welded the two ends together. I put the bolt in between two wood blocks in a vice got the torque to 200 foot pounds to make sure it wouldn`t break when pulling the pulley up. Once I got the pulley pulled almost all the the way up I then put my new bolt in and got my bolt to 200ft lbs. , but you`re supposed to get it up to 240 but at 200 it seemed like something may snap at any moment so I settled for 200. Its been doing good for a month now.
