Alternator, A/C Compressor & Power Steering Pump Pulleys with Mounts
Mark wanted to package the engine accessories low and tight. So as not to interfere with an air-box he has in the works, running the belt over the throttle body wasn’t an option. Mark chose to design, machine and polish his own brackets. The first step was to swap the original Camaro harmonic balancer for a Corvette unit. This moves the belt location forward for more component clearance. To simplify things and make the whole package look great Mark incorporated covers and pulleys from March Performance. The polished rear exit AC compressor is part of the total AC package from Vintage Air. The lower aluminum bracket mounts it to the block. The balancer and clutch covers from March Performance are also shown.
The stock LT-1 power steering pump was utilized. To mount the pump, the 2 existing mounting holes were tapped for 3/8-24 fasteners from the rear. After painting the pump the new pulley from March Performance was pressed on and the pumps location determined. The aluminum bracket attaches to the block at 3 points.
The chrome alternator is a 140 amp, one wire unit from Haywire. Their alternators energize at a much lower rpm than most one-wire alternators on the market. With current and any future electrical power demands Mark wanted an alternator capable of fulfilling the need. The aluminum bracket picks up 2 tapped holes in the head and provides a pivot point for the alternator for belt adjustment.
The last bracket required is to mount the 2 idler pulleys. The idlers from March Performance feature hard anodized wear surfaces and dual roller bearings. The bracket picks up the 2 front lugs on the AC compressor and with the addition of a standoff, one of the water pump bolt locations. To determine belt length a piece of ribbon was routed around the pulleys, then marked and measured. A trip to the local parts store provided the necessary belt. A piece of tapped stainless rod and 2 rod ends provide tensioning.
To finish it off an LT-1 water pump cover from March Performance was bolted in place. The covers and pulleys feature powder coating for durability and ease of maintenance.
