SERVICE INSTRUCTION:

NOTE: Use Earth Stud Repair Kit MRPK4072 to carry out this repair process.

1. NOTE: The plastic earth protection cradle is not compatible with the new stud.

When fitting the repair earth stud, remove the harness cradle from the harness before re-attaching the eyelet to the stud and tightening.

2. Locate broken/cross threaded earth stud.

3. Dress/file the broken stud to a safe and acceptable repair standard.

4. CAUTION: To prevent damage to other components, make sure there are no components in the area that may be damaged by the drilling process.

NOTE: Cleanliness is important to avoid galvanic corrosion.

NOTE: Make sure any swarf is removed/cleaned away.

NOTE: Carry out drilling in close proximity to the broken/cross threaded stud.

NOTE: The stepped cutter should not be used for any other procedure to avoid galvanic corrosion.

Using the stepped cutter supplied in the kit (MRPK4072), drill until you achieve a 15mm diameter hole.

5. Load the new earth stud into the stud applicator gun.

6. NOTE: The earth stud bond is totally self-sealing and watertight; there is no need to dress the hole with any primer before fitting.

Install the new earth stud: Apply pressure to the trigger of the applicator gun until the pressure reduces, this will indicate the applicator gun has reached the end of its cycle.
