4. After confirming clearances and positioning. Mount the
starter.
• If there is not enough clearance, you will need to install
the supplied shim kit by removing the mounting block
(Figure 3). 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".
• The gear mesh is not adjustable on this application. Verify
that all parts are correct for the application (flywheel, block
plate, starter) and verify starter is mounted correctly to
engine plate.
5. 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.
6. 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.
7. 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.
