people with a full unorthadox underdrive pulley set.

 

anybody noticed that on a tt with removed hicas and a non turbo pas pump the belt for the pas pump is miss aligned with the crank pulley?

I just did the belts on my NA and the PS belt goes on the outer two rings of the crank pulley not the inner two, not sure thats any help or different on a TT ?

basically i have a full unorthodox pulley set for a tt. i am fitting it to my na. i have found out the pas pump pulley must sit out about 12 mm more then the na pump (also the na pum,p is a 3 toothed belt where as the tt one is a 4 toothed belt). this would have caused the belt to try and ride up off of the crank pulley. i have made an adaptor kit to allow me to use the tt pulley on the na pump.:)

 

i would assume this would be a problem with the tt boys using the na pas pump when they delete the hicas.

finishing the pulley

The problem lies in that the NA P/S pulley has a different off-set when compared to the TT P/S pulley. If you look carefully at the Unorthodox Racing website you'll see that they list two P/S pulleys - one for the TT the other for the NA.

 

Also, NA P/S pulleys/belts are 3 rib, '90-'94 TT are 4 rib, '95-'99 TT are 3 rib.

 

Nice solution though! :)
