Transmission Oops

So it is time to mate up the 6 speed transmission to the engine but before that I wanted to clean it up a bit an install a new slave cylinder.


Cleaned up well.


So when I removed the old slave cylinder, seen above, and tried to install the new one, the upper bolt hole strips threads the instant I put pressure on it. Crap. Considering how little pressure I used, I think the threads were already damaged and I just finished it off.



You can see the damage in the two pics above.

So now what? Now I need to repair that threaded hole. I used a Helicoil thread repair kit. It uses coil inserts to replace the stripped threads.



First the hole to be repaired is drilled out:



Then the drilled hole is threaded with the supplied tap from the kit:



Using the tool that comes with the repair kit, a coil insert is then installed. In theory the repaired hole is now stronger than the soft threaded aluminum that it replaced.



New slave cylinder installed:



Next task, mate the transmission to the engine.
