50MT Motor 12V and 24V Semi-Solid Link Solenoid Installation Instructions
Notice! Starting Motor must be removed from vehicle before the Semi-Solid Link Solenoid can be removed and replaced. Read all of
the removal and replacement instructions before proceeding.
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. A professional installation specialist should handle
mechanical repairs that are beyond your technical capabilities.
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.
NOTICE! FOLLOW ENGINE AND/OR VEHICLE MANUFACTURER’S INSTRUCTIONS CAREFULLY WHEN REMOVING AND
INSTALLING THE STARTERS.
These instructions describe the removal process for 50MT Conventional and Semi-Solid Link Solenoids and the installation of Semi-Solid
Link Solenoids.
Determine the solenoid type on the starter by the part number stamped on the solenoid metal mounting bracket and proceed to
the instructions for that type of solenoid.

Conventional solenoid part numbers will be 1115662 or lower (Follow instructions A)

Semi-Solid Link solenoid part numbers will be 1115714 or higher (Follow instructions B)
Fasteners, in this document, are referred to by wrench size rather than thread size.
A. Conventional Solenoid Removal Instructions (See illustrations Pg. 2)
1. Remove 3/4” nut [1] on solenoid motor terminal “MTR".
2. Remove 3/4” field terminal nut [2] at the frame.
3. Remove the stamped metal connector strap [3].
4.
Remove the 3/8” nut [4] from ground terminal “G”.
5. Disconnect the flexible ground cable [5] from the “G” terminal.
6. For models with a boot clamp [8], remove clamp by inserting screwdriver into serrated portion of clamp and prying upward. Save
the clamp for reuse.
7. Remove four E8 Torx Head screws [7] that mount solenoid to motor frame.
8. Remove solenoid from lever housing. Plunger and boot will remain on starter.
9. Remove access plug [9] and gasket [10] from front of lever housing, ensuring gasket is removed.
10. Remove 1/2” plunger nut [11], carefully so it does not drop into motor, while holding the plunger securely to prevent rotation.
Dispose of nut.
11. Remove plunger and boot assembly.
B. Semi-Solid Link Solenoid Removal Instructions (See illustrations Pg. 2)
1. Remove 3/4” nut [1] on solenoid motor terminal “MTR".
2. Remove 3/4” field terminal nut [2] at the motor frame.
3. Remove the stamped metal connector strap [3].
4.
Remove the 3/8” nut [4] from ground terminal “G”.
5. Disconnect the flexible ground cable [5] from the “G” terminal.
6. Remove access plug [9] and gasket [10] from front of lever housing, ensuring gasket is removed.
7. Remove 1/2" plunger nut [11] carefully by following the steps outlined below. Proper care must be exercised when completing
this step to avoid personal injury and property damage. Also, to avoid overheating and possible damage to the solenoid,
power should not be applied in excess of one minute.
a) Solenoid must be energized for removal of 1/2" plunger nut [11] to prevent plunger from rotating and damaging the rubber
boot. Warning: Ensure stamped metal connector strap [3] is disconnected to prevent motor from rotating.
i. Check required voltage (12V or 24V) stamped on solenoid bracket to energize solenoid.
ii. Apply appropriate power (12V or 24V) to solenoid between "S" [6] (positive lead) and ground [5] (negative lead)
terminals. Seat the plunger by simultaneously pushing on 1/2" plunger nut [11]. Note: 24 volts can be obtained by
connecting two 12V batteries in series.
b) Remove 1/2” plunger nut [11], carefully so it does not drop into motor, and dispose.
c) Remove power immediately after nut is removed.
