pinto vernier pulley

[Guest cortinamad-gonetoo]

how hard is it to make my own ajustable cam pulley as i have a spare original cam pulley so ive not lost anything if it goes wrong

 

im sure someone on here has made one recently though

Take out the woodruff key. Make sure you use plenty of loctite on the bolt thread and that you do it up properly. The key should only be a locating aid, the bolt provides the clamping force. But if it does slip then its not my fault

Wrong, I spent what seems like half my apprenticeship fitting keys, and if anyone tells you they are just for indexing you are facing a new engine the only reason the bolt is there is to retain the pulley, and possibly stop it fretting, especially as the keyways are broached and the keys are mass produced and there has to be an allowable tollerance. there will be considerable accelleration and decelleration forces applied to the pulley,

If you want to set the cam up with out using a vernier, you used to be able to but woodruff keys with an offset of 0,5 of a degree incriments for setting up.

Noted and understood

 

I got told that it was ok to run without the key years ago and always just assumed that the person who told me was right I was an impressionable teenager at the time so it quite amazing I was even listening enough to take in the mis-information at all glad I didnt have the bottle to try it though and splashed out on an adjustable pulley instead.

 

Anyway, ignore my above post now please

Hey, I sliced the end off my camshaft with an angle grinder to get my pulley to fit, So welding it on seems quite a sensible thing to do to me
