Crank Pulley Pinning
1
Remove the factory fan assembly by
removing the (2) 10mm bolts located on
each side of the fan assembly, accessible
from the top of the vehicle. Disconnect the
electrical connection to the fan. Lift the
fan up off of the lower supports, then out
the bottom of the vehicle for removal.
2
Remove the 21mm crank pulley bolt.
Tech Tip:
Use an impact for ease of
removal. If not available, remove the
access cover to the transmission and use
a sufficient tool to lock the transmission
in place for bolt removal.
3
Place the drill jig onto the crank pulley,
and tighten it into place using the supplied
M14-1.50 x 120mm hex head bolt and
washer.
4
Tape the supplied 1/4” HSS drill bit 1-5/8”
from the tip. Using this taped bit, drill
a hole in the crankshaft and harmonic
balancer, stopping at the tape edge. The
hole will be centered on the OD of the
crankshaft. Do not drill deeper than .800”
into the face of the crankshaft.
