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.

REPLACE THE ONES ON THE STARTER]. ONE STRAP IS COMMON TO THE 37MT & 41MT AND THE
OTHER IS FOR 42MT ONLY. IT IS IMPORTANT TO USE THE CORRECT STRAP AS LABELED [See
illustrations, page 4]. THE STRAPS ON NEWER STARTERS MAY BE THE SAME AS THESE IN PACKAGE.
Determine the series of starting motor and solenoid type you are replacing. The motor series number is
stamped in the Series Block on the starter name tag and the solenoid part number is stamped on the
metal case of the solenoid.
