50MT™ POLE SHOE AND FIELD COIL SERVICE KIT REPLACEMENT INSTRUCTIONS
WARNING!!! ALWAYS USE PROPER EYE PROTECTION WHEN PERFORMING ANY MECHANICAL REPAIRS TO A
VEHICLE – INCLUDING, BUT NOT LIMITED TO, ANY INSTALLATION AND OR REPAIRS TO THE DELCO REMY STARTING
MOTORS. FAILURE TO USE PROPER EYE PROTECTION CAN LEAD TO SERIOUS AND PERMANENT EYE DAMAGE.
Only perform the mechanical functions that you are properly qualified to perform. Mechanical repairs that are beyond your
technical capabilities should be handled by a professional installation specialist.
FOLLOW ENGINE AND/OR VEHICLE MANUFACTURER'S INSTRUCTIONS CAREFULLY WHEN REMOVING AND
INSTALLING THE STARTER.
DISASSEMBLY PROCEDURES FOR REPLACING THE POLE SHOES AND FIELD COIL
DANGER!!! ALWAYS DISCONNECT BATTERY GROUND BEFORE REMOVING OR REPLACING CABLES AT THE
STARTER. FAILURE TO DISCONNECT THE BATTERY GROUND CABLE CAN LEAD TO SERIOUS INJURY.
1. Remove vehicle leads connected to the starter, noting their positions for reinstallation of starter, and remove starter.
2. Remove the access plug and gasket from front of lever housing, ensuring gasket is removed.
3. Carefully remove the conventional solenoid plunger nut so it does not drop into the motor and dispose of it.
For SSL solenoids, remove plunger nut by carefully following these steps. Proper care must be exercised when
completing these steps to avoid personal injury. Also, to avoid overheating and possible damage to the solenoid,
power should not be applied in excess of one minute.
a. DANGER!!! Ensure the stamped metal connector strap is disconnected from the field terminal to prevent the
possibility of motor rotating.
b. Solenoid must be energized for removal of plunger nut to prevent plunger from rotating and damaging the rubber boot.
Apply appropriate power (12V or 24V) to solenoid between the switch "S" (+) and ground "G" (-) terminals.
c.
d. Seat the plunger by simultaneously pushing on plunger nut. Note: 24 volts can be obtained by connecting two 12V
batteries in series.
e. Carefully remove the plunger nut so it does not drop into the motor.
f. Remove power immediately after nut is removed.
4. Remove the six (6) drive housing mounting bolts and the drive housing. Mark the drive and lever housings positions for
reassembly, place the motor in a safe horizontal position.
5. From the insulated/ground terminal, carefully noting orientation for reassembly, remove all remaining hardware. Check the
condition of insulators and sealing features and consider replacing them if they are damaged or excessively worn.
6. Remove the six (6) CE screws.
7. Remove the 3 plugs from the frame to allow removing the three (3) field to positive brushes attaching screws for 12V, 24V &
32V models or two (2) field to positive brushes attaching screws for 64V models.
8. Remove the CE housing and armature assembly as a unit. It's best to remove them together to keep the brushes contained.
9. Remove solenoid-to-motor field connector strap or lead (for 32V/64V models)
10. Remove the seven (7) lever housing mounting bolts and four (4) solenoid mounting bolts, remove the frame and field assembly
11. Remove the twelve (12) pole shoe screws and six (6) pole shoes. If sealing on screws are damaged, replace them with new
pole shoe screw assemblies.
12. Remove the insulator paper and release the field coil from the frame.
REASSEMBLY PROCEDURES FOR REPLACING THE POLE SHOES AND FRAME AND FIELD
1. Install the inside terminal insulator and insulator washer into the field coil terminal.
2. Install field coil, insulator strip and three (3) papers into the frame.
3. Install the four (6) pole shoes and twelve (12) pole shoe screws assemblies. Torque screws to 20.34-67.79 Nm (180-600 lb in).
Consider hitting the coil terminals slightly to ensure they don't touch the insulation paper. This will also help to avoid any
rubbing between the armature and terminals.
4. Install the frame & field assembly, aligning it with the marks or solenoid position with seven (7) screws to the lever housing.
Torque screws to 16.27-22.03 Nm (144-195 lb-in).
5. Install the CE housing, brush-plate and armature on the starter with the screws, assuring the same position as removed.
Attach the three (3) field to positive brushes attaching screws for 12V, 24V & 32V models or two (2) field to positive brushes
attaching screws for 64V models over the plug holes. Torque screws to 2.26-4.52 Nm (20-40 lb in) for punched holes or
3.62-5.20 Nm (32-46 lb in) for extruded holes.
