Serpentine Belt System - Vintage Air's Serpentine System

Next we prepared the crankshaft to mount the crankshaft pulley. Again, the proper tool should be used to mount and position the harmonic balancer, and, if necessary, any spacer necessary to align the crankshaft pulley with the water pump pulley.

Our Rattler harmonic balancer came from Speed-O-Motive with an aluminum spacer mounted in front. We returned it to the front of the harmonic balancer before mounting the crankshaft pulley.

The chrome-plated crankshaft pulley is about the same diameter as the harmonic balancer. It mounts with four supplied (31/48x16x111/44) stainless steel 12-point bolts and AN washers.

The chrome-plated water pump pulley mounts to the water pump with four (51/416x24x31/44) stainless steel 12-point bolts with four AN washers.

After the water pump pulley was secured, we checked the serpentine belt for length. We decided the belt-tensioner had to be rotated so we could install it.

Rotating the belt tensioner required a separate pair of hands, but the belt slipped into place without any problem. Then we noticed we had removed the A/C hard lines and needed to remount them to the front main bracket. No problem, just a minor setback.

We found it helpful to rotate the crankshaft to remove and reinstall the serpentine belt.

Now we have the A/C hard lines back in place and the serpentine belt properly installed. It's apparent that this compact system is well designed, and all the pulleys and accessory hardware fit extremely well.

Now we could install the polished belt-tensioner cover with one small (flat and flush-fitting) Allen-head screw.
