Re-manufactured 6 volt starter motor.
Outright sale, no exchange necessary.
A new armature bush (111-301-155) must be fitted into the gearbox when fitting. Please also check the condition of your wiring - most reported faults in new starter operation are due to old wiring from the ignition switch producing low voltage at the starter motor solenoid. You can check if non-operation is due to a wiring issue by testing with a feed direct from the battery. If in doubt then seek professional advice.
