i have removed the smog from my truck when the engine was rebuilt and just reinstalled the pump to carry the belt. well now that the pump has locked up on me, i am removing it and need the shorter belt part number. i searched but was unable to find it.

 

 

I like the belt diagram , good , but if the truck sees any high RPMs the air pump idler pulley helps kep the belt running straight ...Lew

 

you do realize that you can just take the pump off, gut it, and grease it... then it will run just like and idler pully.... and it's free to do without having to buy another belt... just a thought.
