Katech Adjustable Tensioner Install and Torque Settings I have been asked many times about all the specs for installing a Katech Adjustable Tensioner, and I could never find the instructions. I found them, so here they are. I just want to make sure this is in the LS1Tech archive (for as long as this forum is around).

Tensioner is not assembled for installation - Customer must check all final torque specs upon installation onto engine.

2. Torque M2437 shoulder bolt to 25 ft-lbs.
3. Insert 7/16-20 bolt and washer into 2426 through slot in 2380.
4. Install pulley (not supplied, stock replacement is fine, easily found at Autozone, etc) onto 2426, torque to 40 ft-lbs.
