NOTE: It is beneficial and possibly necessary to obtain the commutator end (CE) service
package, for reassembly of the field
coil assembly. It is preferable to use new, undamaged parts.
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.

FOLLOW ENGINE AND/OR VEHICLE MANUFACTURER'S INSTRUCTIONS CAREFULLY WHEN REMOVING AND INSTALLING
THE STARTER.
DISASSEMBLY PROCEDURES FOR REPLACING THE FIELD COIL ASSEMBLY AND/OR POLE SHOES
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 five (5) lever housing screws, mark frame & LH position, and place starter in a vertical secured position, if possible.
3. Remove clip from over crank protection (OCP) connector, if applicable.
4. From the insulated/ground terminal, carefully noting orientation, remove all parts including the solenoid ground lead. Check the
condition of insulators and sealing features and consider replacing them if they are damaged or excessively worn.
5. Remove the four (4) CE screws and CE housing.
6. Remove the remaining insulators from the ground stud, carefully noting orientation for reassembly. Check the condition of insulators
and sealing features and consider replacing them if they are damaged or excessively worn.
7. Pull the four (4) brush assemblies back and contain with brush springs to remove pressure from the commutator.
8. Remove the two (2) screws connecting positive field coil leads to the brush assemblies and remove the brush plate assembly.
9. Remove the connector from field terminal and solenoid motor terminal.
10. Remove the five (5) screws attaching frame & field to shift lever housing and remove frame and field assembly without removin g the
armature.
11. Remove the eight (8) pole shoe screws and four (4) pole shoes. If sealing on screws are damaged, replace them with new pole shoe
screw assemblies.
12. Remove the field coil assembly, insulation strip, terminal insulator and grommet.
REASSEMBLY PROCEDURES FOR REPLACING THE FIELD COIL ASSEMBLY
1. Install the inside terminal insulator, field coil assembly and insulation strip into the frame. (See graphic, page 2)
2. Install the four (4) pole shoes, with notched end toward the CE, and eight (8) pole shoe screws assemblies. Torque screws to
20.3-67.8 Nm (15-50 lb ft). Consider hitting the coil terminal s slightly to ensure they don’t touch the insulation paper. This will also
help to avoid any rubbing between the armature and terminals.
3. Install the frame & field assembly, aligning it with the marks or solenoid position with five (5) screws. Torque the screws to
16.3-23.1 Nm (144-204 lb-in).
4. Install the brush plate assembly over the locator pins, noting position of the ground stud.
5. Attach the positive field coil and positive brush leads with the two (2) screws, as removed. Torque the screws to 2.3-4.5 Nm
(20-40 lb in).
6. Push the brushes down into place, assuring the brush springs are positioned on top of the brushes.
7. Install the square fiber insulator onto the ground stud.
8.
Apply bearing type grease onto CE housing’s inner diameter where the frame o’ring is seated and apply a small amount of SAE20
oil into the bushing area.
9. Install CE housing over the locator pins and install CE attaching screws, assuring the square fiber washer is properly aligned with
the anti-turn feature on the CE housing.
10. On models with OCP, ensure the OCP connector is seated properly in the housing and replace the retainer clip.
11. Torque the CE screws to 4.5-6.8 Nm
(40-60 lb in).
