3. After confirming clearances and position of the solenoid, it is

time to check the pinion engagement to the ring gear. This

is done by gently prying out the pinion gear to the ring gear.

The pinion should engage by 1/4" minimum and 3/8" max on

to the ring gear (Figure 2).

• If there is not enough clearance, you will need to install the

supplied shim kit by removing the mounting block (Figure

3). If the pinion gear engages too far onto the ring gear,

there will be issues with disengagement. MSD supplies a

shim ring to move the pinion 0.060". Remove the mounting

block and place the small shim ring in the bearing bore and

install the outer shim on the support housing. Reinstall the

mounting block. This will move the pinion gear into the starter

approximately 0.060".

4. With the starter mounted and gear engagement confirmed,

it is time to connect the wires. The switch wire that connects

to the solenoid should be at least 12-gauge (Figure 4). For

alternative wiring to incorporate the factory remote

solenoid, See Figure 5.

5. Attach the battery cable. The gauge of the battery

cable depends on its length. Using the proper

gauge wire is important to the operation of the

starter. Both the positive and ground wires must

be able to meet the demands of the starter. The

chart in Figure 5 shows the recommended sizes.

Be sure to route the wire away from the exhaust

and moving parts of the engine.

6. Connect the battery terminals and start the engine.
IMPORTANT: Never operate a starter for more than

30 seconds at a time without letting it

cool for at least two minutes.
