Procedure G - Install "Keen-Sert(s)" As Needed

Drill Out Broken Screw(s):





1. Obtain the Thread Repair Kit J-46530 and make sure all components are in the kit (see Figure C1).

NOTE:
Thread Repair Kit and additional threaded inserts ("Keen-Sert") can be ordered from TECH-MATE. The "Keen-Sert" part number is J-46530-5.





2. Install (push down until fully seated) and tighten the Drill Guide (identified by "DRILL ONLY") onto the "boss" of the broken screw (see Figure G2).

^ Make sure the Drill Guide is securely tightened.





3. Drill out the broken screw with the special Drill Bit from the Thread Repair Kit (see Figure G3).

IMPORTANT:

^ Use a suitable lubricant when drilling.

^ Don't drill too fast as it will over-heat the drill bit.

^ Make sure the drill bit bottoms out against the drill bit stop.

4. When finished drilling, remove the Drill Guide.

Tap New Threads in Drilled-Out Hole(s):





5. Install (push down until fully seated) and tighten the Tapping Guide (identified by "TAP ONLY") onto the drilled-out "boss" (see Figure G4).





6. Tap new threads in the drilled-out hole with the special Tap from the Thread Repair Kit (see Figure G5).

NOTE:

^ Turn the tap handle to the right (clockwise)

^ After one rotation, turn the tap handle to the left one-half turn. Do this during the entire tapping process to keep the tap from clogging.

^ Use a suitable lubricant when tapping the threads.

^ Make sure the tap bottoms out against the tap stop.

7. Remove the Tapping Guide.

^ Clean the newly threaded hole.

Install Threaded Insert ("Keen-Sert"):





8. Screw the Threaded Insert all the way (clockwise) into the newly threaded hole (see Figure G6).

^ Make sure the top thread of the Threaded Insert is flush with top of the hole (see Figure G6).





9. Drive the Lock Tabs down flush with the special Lock Tab Driver tool and a hammer (see Figure G7).

10. Return to the appropriate Service Procedure step.
