FIELD WINDING TEST
1. Connect one ohmmeter lead to field coil lead ("M" terminal wire). Connect other lead of ohmmeter to
soldered portion of brush lead. If continuity does not exist, repair or replace field coil.

wire) and other ohmmeter lead to field coil housing. If continuity exists, repair or replace field coil.
OVERRUNNING CLUTCH PINION DRIVE
Hold overrunning clutch housing and turn pinion gear by hand. If pinion turns in both directions or does not
turn at all, clutch is faulty. Replace clutch. DO NOT clean overrunning clutch with solvent, as it is packed with
grease and sealed by manufacturer.
REMOVAL & INSTALLATION
Removal & Installation
