914World.com _ 914World Garage _ Tranny leak

Posted by: Deano Aug 17 2005, 01:39 PM

I've got a slow leak were the speedo drive connects to the tranny. It really just seeps, but after a while it does drip. It's a side shifter. Any suggestions? I've always left tranny work to others, so I've never really worked on it.
Help please !?!?

Theres a bolt that holds the speedo drive in. Back that out, pull out the drive, replace the O Ring. If that doesnt help, lightly coat the O Ring in Permatex Form a gasket (3H).

Cool thanks, I'll give it a try. I'll let you know how it goes.

Drain the tranny first........

I would use some hi temp synthetic grease instead of any type of sealer since the tranny gets really hot and can cook sealers.

This is one of the easiest leaks to fix if it is the o-ring. Like Matt said, just disconnect the cable from the drive, pull the retaining bolt and twist it out. Replace the o-ring and re-install. You don't even have to drain the tranny if you get the ass end high enough. Shouldn't take more that 20 minutes...

You guys rock. Thanks for all of the input.

I Just came in from the garage, it worked like a charm. You were right, 20 minutes and I was back on the road. After a spirited drive it ws dry as a bone. Thanks again to all of you, once again you have come through for me!

Well, too late. But for the rest, the retaining bolt is torqued to 3 ft lbs.

is the retaining bolt, the one that is in the back (approximately 10 mm)?

Posted by: Bleyseng Aug 18 2005, 06:53 AM

Yep, the one thats usually stripped out due to idiots over tightening it.

Posted by: Deano Aug 18 2005, 07:43 AM

Yep, it's 13mm and I didn't use a torque wrench, but I may have put about 5 ft/lbs on it. By the way I was able to find a perfect fit O-ring at Menards.

I dont know if mine is stripped or not. it does not turn easily, it is snug...but still turns...I was afraid to overtighten it...but wouldnt be surprised if it is stripped...mine is also seeping, I ordered a new speedo angle drive seal...and will swap it out and check it out.
thanks
Joe
