Drip, drip goes the tranny.

I though I had it fixed by wrapping the PG cable in rescue tape. Nope, it still drips when the TC drains down. Not from the front, or the TV lever shaft. Drips fall from the lower control arm mount bolts. Pan looks dry all the way around the gasket. Where is it coming from? How do I investigate the source further?

Check the bolts attaching PG to the diff.

May be the governor o-ring.

Indicators point to the governor. The drips jump from the trans to the diff area and down to the lower control arm. Seepage is visible under the governor.

How do I get the governor off and can I get an o-ring from a flaps or good hardware store? Does it need to be viton?

How to remove governor (LM/FC):

1) Remove bolt
2) Pull governor out of transmission

Hardware store O-ring should be fine.

The governor retaining bolt is next to the governor. A good o-ring will seal it up, doesn't necessarily have to be Viton. Pull the bolt and slide the governor out, clean the mating surfaces and install new o-ring on governor. Install governor and retaining bolt, easy peasy!

I guess I'm "shaking the governor's hand" to use my favorite euphemism for self abuse. The governor is out and is very crusty and the o-ring has a flat spot. I am cleaning up the dome to determine if it is leaking at the seam. I don't think so but I will fill with fluid to check.

Forgot, is the shaft supposed to be floppy when it is out of the trans case boss?

No PG drips this morning!

Think I got it with the governor O-ring.

Just a minute drip now that smelled like diff oil.

Going 225 miles on Thursday. Back to Chicago.

I now have a handy breaker bar I made with a cut down socket to do emergency fan belts. Hope I don't have to use it.

Doing this job today on Gem.

Didn't do it when I did the cable.

Of course it started leaking next day.

Haven't heard from handswheels in a while?

Did that job and others on my PG earlier this week. My o-ring was hard and hard had flattened when sealing was an impossibility.

Should have done it when I did the cable six months ago.

Now I can't find the o-ring but...didn't take it apart yet.

Got the bolt all cleaned off and ready...just need an o-ring.

It is in a small zip lock bag along with a CA Corvair card. moody smiley

Go to Harbor Freight and get a box of Nitrile o-rings and a box of Viton O-rings. Will do most jobs you run into and last forever.
