ATI DBxxxI-006  ProCharger 6 Rib Blower Belt

These belts are currently only offered to those who know the ProCharger part number from their current belt. Please put the part number in the "notes" section of the order form.

Blower belts stretch quite a bit during the first hour of use, and many appear to be too short when they are new. Try putting the belt around everything but the crank pulley, then put it around the crank pulley as far as possible, and crank the engine over to get it on. Allow the belt to break in by taking it easy on it for the first hour, you may have to readjust the tensioner after the belt is broken in. 

Systems that use standard series pulleys
P1SC, P1SC-1, P1SC-2, D1, D1SC, F-1D, F1, F1-A, F1-C, F1-R Superchargers

Remove the driver's upper and the lower stand to

bracket mounting bolts and loosen the passenger upper

bolt to allow bracket to be pivoted enough for the belt to

be installed over the lower standoff. Hang the belt on

the standoff and install and tighten all stand to bracket

bolts.

Some belts will be easier to install if you pivot the

supercharger in the bracket using the lower mounting

bolt only. Install the belt over the crank pulley and then

finish installing the blower mounting bolts. The antisway

bar may need to be lowered to facillitate

installation of some of the mounting bolts.
