What is this part?

Over the past year, I have replaced many oil
seals and reduced the oil leaks from Noah's
flood to a single slow drip.....drip.

I isolated the leak to where the tranny and
engine meet. So I ordered both gearbox and
rear engine oil seals. I have gearbox
oil seal part No. 520-060 and I can't quite
figure out where it goes.

Here is photo of the inside gearbox. BTW-
there was no gasket, just this orange goo.
Fairly certain this is my leak source.

I have a proper gasket but I don't know
where the oil seal goes or how to take the
old one out. Any and all help appreciated.

Sorry for the twin posts but I'm stuck. Dale

The seal goes inside the piece you took off. See this from Moss site. Item 53 (part # 520-060) goes into item 54. /bcforum/images/%%GRAEMLIN_URL%%/smile.gif
 
You might want to make sure the breather on the tranny is clean. That may cause a leak as well.
 
Looks to me like there is gasket sealer(orange)on an old seal perhaps. If you have a new seal, take the old one out and carefully remove that orange stuff with a razor blade. That may be your leak, and you definately don't want to put another gasket on top of the old one!

Whew! That's a lot of things.

1. I will take a look at the part I took off and
try to find the old oil seal.

2. I have no idea what a tranny breather is or
where it is located? Where do I look?

3. No existing gasket. Orange goo directly on bare
metal. Yes, I'll take it off with a blade.

4. Should I put Permatex gasket sealant on the new
gasket I will install?

thnaks as always,

dale
 
That isn't a gasket (the darker area) with the goo around it??

Yes, it looks to me that there is still a gasket there. If you look closely, the holes on the "gasket" don't line up with the threaded holes in the tranny. It looks like it shifted. I'd bet you could just flick it off with your finger nail.
 
Dale,

Before you go scraping that orange goo and gasket off cut some duct tape or something to cover over that imput shaft bearing and then wrap some tape around those splines to protect the new seal from possibly getting damaged whence re-installed.
 
Dale,

When installing your new seal be careful to apply pressure evenly so it does not become distorted and become bent or twisted. Seal drivers are available from tool companies, but you could also use something flat like a block of wood on end. Just so it covers the entire seal. Use some caution when starting it so it starts evenly, this is the most important time and when most seals are ruined.

Like Harry said, the rubber seal lip can be easily torn or cut when going over the tranny shaft. Take care not to touch it to the shaft especially when going over the splines. A little oil or grease might help it when going the rest of the way.

Oh, I almost forgot, make sure the flat side is to the outside and the pocket side, where you can see the little spring, is on the inside of the cover.
 
And use plenty of grease to lube it while putting into place, after carefully cleaning the area into which it will be installed.
 
I put masking tape and/or a poly milk bag over the shaft so the seal will not get cut by the sharp corners on the splines when I'm installing the assembly with the seal inside. Make sure that the "bump" on the housing is oriented as per the manual. Also use copper washers under the bolt heads so the threaded holes will be sealed - so the oil won't leak through these bolt holes. Wire lock the heads of the bolts so they don't loosen.
