G50 Trans mount stud help and notes
Two of the (4) transmission studs came out when I was removing the mount to replace the G50 mount bushings. Studs are in great shape and were dry.
Can anyone tell me if I should just loctite them back in, and if they get torqued or not? The mounting nut torque is 18 ft-lb, but what torque do you use on the stud, the same or more? I also noted a slight bummer - the 2 large anodized bottom washers were pretty rusted on the inside (bushing face). (PP here I come). |
Steely I am also having some g50 shifting problems so I re-torgued the studs to 18 and also checked the rubber mounts. The rubber looks good but I dont think you can just replace the rubber bushings, let me know if you can.

The mounts can be replaced - they are 2-part poly graphite - part no is PEL-RSRMTM.

This is the inside face of the large lower (seat) washer. Both are like this.

Steely thanks for the part number, I am guessing the old need to be pressed out and the new pressed in?
|
Yeah Len, but I just cut mine out (no press). I cut the lip of one side and then pried it out with a BF screwdriver.
Not sure if you saw it, but I threw a link up there to another Pelicans thread that has pics and info. |
Thanks Dan, sorry I could not answer your orig. question but you did help me.

Lenny - No problem sir - that is what it's all about!
Look into the thread I have up there - Wevo was doing a G50 bushing too that you might consider, but I they or another company may require you to send the crossmember to them for the install. And good luck with the shifting issue. There's an answer out there for me :-) |
torque answer

Don't worry too much about the torque for the studs. Snug them in there and some red Loctite is fine to keep them in place.
Nothing strikes me as odd about those washers rusting inside. They sit with the cup facing inward, so they are ripe to catch water. Actually they're not anodized. Steel isn't commonly anodized- usually aluminum alloys (like the Fuchs wheels and black window trim). The original fastener plating material on fasteners from Porsche was cadmium. Cadmium isn't that common anymore since it's not all that environmentally friendly. More common today is zinc. |
Thanks Kevin - my bad on the anodize, is the finish alodine - just curious. Am somewhat familiar with cad plated cable connectors - superior quality but bad in the respect you mention - had no idea Porsche used it.
Really appreciate the stud info. Now I just wait for the mail man. |
The mail man........... Great to find what he leaves on the doorstep and hate to see how he supports the credit card debt! Trying to get the racecar sorted out for the coming season and it seems the orders are going out fast and furious! :mad:
:D |
Studs don't have a torque value. Just make sure they don't go in too deep. You need enough for the proper amount of turns for the nut.
The suggestions above are right on, clean, chase, red loctite, double nut..... |
