Important: Read the instructions before attempting the installation.
Note: On some vehicles the MSD Crank Trigger Kit may require slight modifications to accommodate
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 driver's side of the
engine. 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.
3. Check and make sure the wheel is positioned correctly
with the pickup and torque the trigger wheel bolts to 25
- 30 lb-ft. The pickup should be centered to the edge of
the trigger wheel (Figure 2). If not, it may be necessary
to add or delete shims to the pickup bracket to achieve
the proper position.
