Figure 9: Attaching Bridge Bracket
A] Install the bridge bracket to the three water pump spacer nuts, the top
front, and bottom front compressor ear by applying anti-seize to and using
five 8mm-1.25 x 25mm 12 pt. cap screws.
B] The bridge bracket also attaches to the tensioner using a
8mm-1.25 x 40mm flat socket cap screw (installs in lower boss through
bracket and tensioner into spacer nut), and a 8mm-1.25 x 25mm flat
socket cap screw (installs through bracket into tensioner).
NOTE: Apply anti-seize to threads before installing. The compressor
shoulder bolt on the lower rear ear and/or water pump spacer nuts may
need to be loosened to help align the bridge bracket with screw holes.
Figure 10: Attaching Alternator
A] Place the alternator behind the bridge bracket apply anti-seize to
threads and install the 10mm-1.5 x 80mm 12 pt. cap screw in the lower
alternator mounting hole.
Note: The alternator mounting boss may vary in width due to the
polishing process. 10mm shim washers are provided to shim alternator to
bridge bracket (washers may not be needed).
B] Complete alternator installation using one 8mm-1.25 x 25mm 12 pt.
cap screw by applying anti-seize to threads and threading through the
bridge bracket into the top ear of the alternator.
At this point we are ready to tighten the hex flange bolt on tensioner
bracket and compressor shoulder bolt. Once these are tightened you
may then tighten all bolts on the bridge bracket assembly.
