The Repair
Drill. Tap. Insert.
A permanent thread repair done the way pro engine shops do it — minus the machine shop bill. Here's the whole process, start to finish.
Safety first:the supplied drill bit has a pre-set depth stop. It bottoms out at the correct depth so you physically can't punch too far into the block — the one mistake that scraps a casting.
Drill
Remove the damaged threads with the supplied drill bit. The pre-set depth stop bottoms out before you can go too deep — no measuring, no guesswork, no scrapped block.
Tap
Cut fresh, oversized threads with the correct-size tap. Go slow, back off to clear chips, and keep it square. Clean the hole when you're done.
Insert
Thread a hardened sleeve onto the install tool and drive it to depth. The insert locks in, leaving a clean, torque-ready thread that's stronger than the original aluminum.
