MSD 8636 Chrysler Big Block Crank Trigger Kit Installation - Manual

Important: Read the instructions before attempting the installation.
Note: On some vehicles the MSD Crank Trigger Kit may require slight modifications to accomodate
special engine plates, pulley systems, etc.
INSTALLING THE PICKUP AND BRACKET
1. Mount the pickup holder onto the bracket using the two fine thread bolts (Figure 1). The pickup
base will only install one way, do not try to force the bolts in, and hand tighten the bolts.
2. Install the bracket onto the engine. The
bracket may be mounted on either side
of the balancer. Be sure to use the correct
length bolts and shims in the proper
location.
3. Install the pickup and locknut into the
holder. Do not tighten the locknut at this
time.
INSTALLING THE TRIGGER
WHEEL
1. Position the No. 1 cylinder under compression
at the desired total timing. Install the trigger
wheel centering ring onto the harmonic
balancer of the engine.
2. Position the trigger wheel onto the harmonic
balancer and centering ring so one of the four magnets lines up with the center of the non magnetic
pickup. Make sure the wheel is mounted so it rotates in the direction of the arrow on the wheel. If
necessary, slide the pickup in its mount until it properly lines up with the trigger wheel magnet.
