INSTALLATION INFO
NOISE
If there is a high pitch whine during cranking, the pinion to ring gear engagement may be out of
specification, on the high side. If there is a whine after cranking there may be too little of clearance. The
gear mesh spec is .020"-.035" (Figure 4).
SLOW CRANKING
The most common cause is due to low input voltage. The battery should be checked, but also inspect
the battery wires, terminals, connections or switches.
DISCONNECT SWITCHES
Most sanctioning bodies require an emergency disconnect switch. Be sure to use a heavy duty switch
that is capable of handling high current. Some starters may pull over 700 amps while cranking. Most
disconnect switches are rated at continuous and intermittent amps. Make sure to use a switch that
exceeds your starting and electrical system requirements.
