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.

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.
