Proper Bearing Carrier Stud Installation

[Ralph Z.]

About to replace all of the studs on a MK8 gearbox bearing carrier and cover. What is the proper way to install?

Run the stud all the way in until it stops at the end of the thread?

Use a thread locking material and thread the stud to the end of the case?

As always, thanks in advance.

Thread them in with a locking compound, and put a spacer and nut (or the bearing carrier itself) to 'pull' the stud threads into contact with the blind hole threads. Don't tighten them into the bottom, but get close. Leave it for 24hrs (or whatever your locking compound requires).

Make sure everything is very clean before starting.

Don't overdo the locking compound, no need for it to squish out everywhere when the stud is in.

For final assembly, use nylon locking nuts, not physically deformed (jet / k) nuts, as they may damage the stud, or rotate it out under disassembly.

That's my process anyway - I'm sure there are loads of ways that will work.

Excellent! Thanks.

Gary is spot on with his comments. If you follow his instructions with red Loctite you will never have a stud back out.

I used to lathe off a few threads at the end of the stud, and then turn a 130 degree taper on the end (to match the usual tap drill tip angle), then tighten them down to bottom in the hole Just enough torque to load the threads a little in the same direction that the nut will take it), with either blue or red Loctite.

Gary has got it ..

Stack oversized nuts on the stud . Put a washer on and a plain ol nut .
1/4 turn when tight .
This will squeeze the Loctite to the back side of the stud .
You will need heat if you want to remove them
