TIME-SERT INSTALLATION INSTRUCTIONS 02 2507 Metric Threads: Phase 1 Drill out the damaged thread all the way to the bottom using a HSS drill bit A. Be sure to keep the bore hole aligned. Phase 2 Machine the borehole with seat cutter B deep enough that the depth stop gets in contact with the workpiece. Phase 3 Using thread tap C, cut the thread for the TIME-SERT bush. Be sure to keep the bore hole aligned. Phase 4 Blow out the shavings. Lubricate insertion tool D and screw in bush manually into the TIME-SERT thread. Phase 5 Once the bush sits flush with the surface, the remaining threads are formed using the insertion tool D. The screw-in resistance increases noticeably. Phase 6 In this phase, the semi-finished threads of the bush are pressed outward. The insertion tool D presses excess material into the workpiece. The repair is complete when the tool can be turned with noticeably less resistance. Phase 1 Screw in stepped tap A into the remaining thread. Phase 2 Snap socket wrench D onto stepped tap A and continue turning until the outer tap protrudes about 5 mm from the thread. In this way, the old thread is removed and the new one is cut in a single operation. Phase 3 The stepped tap A remains in the thread. Slide the seat cutter B onto the stepped tap. Keep turning until the seat has been completely cut out. The entire seating surface must be bright. Phase 4 Blow out the shavings. Screw in TIME-SERT bush manually with a few turns - or using insertion tool C. Make sure to lubricate the insertion tool first. Phase 5 Screw in the bush until it is seated securely using the lubricated insertion tool C and socket wrench D. The screw-in resistance will increase noticeably. Continue turning until the resistance drops noticeably. Phase 6 The repair is complete. The threaded bush is now compression proof and secured against unscrewing.
