Next install the front bracket using the longest socket head bolt in the top hole and 1 "B" spacer between the two brackets and one "A" spacer between the rear bracket and the cylinder head.

Now install the R4 compressor between the two brackets using the two 110mm bolts with stainless washers on both sides and the lock nuts on the rear side.

While lifting the weight of the compressor.

Tighten all bolts to 28 ft lbs. Start with thecounter sunk bolts first, rear bracket to cylinder head, then the front bracket, and finally the compressor.

This spaces the pulley further off of the front bracket.

This bolt comes with a locknut and stainless washer for the rear to keep this locked into place.
