1. Take out one bolt at a time.
2. Install one stud at a time using a stud with a allen slot in one side with
Loctite. (A allen wrench that can be used with a ratchet makes it
easier.) (Very Tight i.e. 120"lbs/10ft lbs.)
3. When all (4) four studs are installed pull MG back out of bracket and install
(4) four 5/16 x 18 serrated nuts with serration facing bracket. (Tighten
anyway that works for you.(Very Firm)
4. Slide MG back into bracket and install four 5/16 x 18 serrated nuts with
serration facing bracket. Tighten VERY FIRM or 24 to 28ft lbs. Run slide
in/out twice min. and recheck torque.
FYI, this works on Square Shaft drives and Torqueflex (Fenner). I did my kitchen slide last February and "FIXED" my kitchen slide (Square Shaft). I just tackled my bedroom slide this this weekend. I Tried many of the suggestions in previous post and none of them would stay tight or hold torque. THEN I watched how to remove the Torqueflex drive and slide the motor back on the shaft to install the serrated nut I needed to remount the MG to the bracket.....
I am "FIXED" Y'ahoo!!!!!
This is MY Fix..........
An alternative is also the Stage 8 kit.
