Pinion Clearance Check: Notes

Connect an electrical source of 12 volts between solenoid "S" terminal and ground. Energize solenoid, release and push away from stop retainer as far as possible. Use feeler gauge and check clearance between pinion and retainer. Clearance should be 0.010 - 0.140".

NOTE: Pinion clearance is not adjustable. If clearance is not within specifications, motor must be disassembled and checked for defects.
