LS1 Short Belt Modification


Recommended Posts

In order to overcome the small belt contact the original short belt conversion offered I have added an extra pulley to allow more belt contact area for the waterpump.

 

You have to clearance 1 bolt (the bottom alternator bolt) to clear the belt.

 

I got the aftermarket pulley from ebay and the belt at NAPA. The belt is a 6 rib 55 ¼" long, 060547.

 

Here’s a picture (about 100k)

Hey Dale!!

I pondered the belt routing also. Without a long story, my belt routing is the same as yours except...... I kept the tensioner in the oringinal spot, upper right (passenger) and I installled the idler (groved) next to the waterpump for added tension. Idler and belt are both from Goodyear. My crank pulley an underdrive from SLP. Anybody interested in part numbers, Let me know!
