914World.com _ 914World Garage _ Another Speedo Angle Drive Post
Posted by: kconway Aug 15 2007, 08:14 PM
CRAP! I went down to the local dealership to order the seals for the speedo angle drive and came home with these (less penny) -> 
So, the aluminum washer on the left is item #24 (sealing washer) from the exploded view in PET. I could have sworn I told the counter guy I needed #25 & #26. Anyway, I pulled my old angle drive out and couldn't find this part anywhere. Anybody know where it goes? Got photos? Maybe this is why mine leaks? 
Edit
so I found this where it shows what looks like the same washer but its a sloppy fit, can someone confirm?

I just replaced the o-ring and oil seal in mine, but did not replace the washer. When you unscrew the speedo drive from its housing that press fits into the rear cover of the tranny, you will see the washer. It fits into the housing and helps hold the oil seal in place. The washer should fit very tight.
If you are not going to replace the oil seal, I would just leave the current washer in its place. However, while you are in there, you probably should get a new oil seal and replace. Use a hooked pick to get behind the washer and you should be able to pop it loose. Then it is real easy to get the old seal out, install the new, and press the washer back in so it sits nice and flat inside the housing. Then screw the speedo drive back in, and install the whole assembly back in the tranny. Be careful not to strip the threads in the case where the screw holds the whole assembly in the tranny case, it is easy to do. I think the torque value is some thing like 3-5 ft/lbs.
Hope this helps.

Gordon,
Is the blue seal shown here the one your talking about? I don't see the washer here but perhaps its crushed into place?

Yep, that is the oil seal, and that is the washer in front of the oil seal. At first glance, the washer looks like it is a part of the housing, but if you look close you will see that the washer is seperate, just a tight press fit. Use a pick or something to get behind it, and give it a hard tug. It should pop out, giving you access to the seal. Otherwise, there would be no way to remove the old oil seal and install the new. When you are done, the washer should not be loose, but pressed tightly back in the housing.

Old thread, but related to what I'm doing.
Which way does the radial sealing ring (999 113 036 50) supposed to be installed? I just picked one up from the dealer and notice the two sides are different. On one side I can see a spring.
Is the arrow pointing to the flat side with the spring on the other side?

I put the spring side inboard. Yes, that is the flat side, spring is farside.

Can this be done with the transmission in the car and the case full of gear oil, or will it all come sqirting out while being done.
I have one drip left and it is that seal. The case if full of new Spepco, so I am deciding whether to let it be for now.

If you remove the entire drive, gear oil will pour out. Promise.

Thanks Mark, That's what I thought. The fact that the engine I built does not drip a drop and the only drip is coming from that drive is a source of satisfaction.
I will leave it be.

Ugg..mine is leaking badly as well and that stuff smells NASTY when it hits the exhaust!

The "kit" we sell includes all but the aluminum washer. New internal seal, a second seal to help keep it from dripping and a complete new aluminum "bushing"
For $65 you get it all.
The dealership wants over $100 just for the bushing. This started as a rebuild service that McMark was doing and turned it into a outright purchase as we could bring the cost down and you aren't without a part you need (no downtime).
