5. To check the pinion gear mesh, gently pry the
gear out to engage to the ring gear. (Sometimes
the pinion will not retract. This is normal.) Insert
a wire gauge as shown in Figure 4. As a gauge,
a standard 1.25" paperclip could be used as
they generally are about .035" in diameter. There
should be .020"-.035" clearance between the ring
gear tooth and the pinion gear.
• If there is not enough clearance, install one
of the supplied shims and check again.
• If there is too much clearance, install a shim
under the outer bolt only. This will tighten the
clearance.
6. The switch wire that connects to the solenoid
should be at least 12-gauge (Figure 5).
Note: If your original starter had wire going to a
second terminal, an ‘R’ terminal, this can
generally be bypassed. See the information
on page 3 of the instructions for more details.
7. Attach the battery cable. The size 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.
8. 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.
