NP208 Reseal

[Chevy305]

So I'm in the process of resealing my 208 and have a few questions.

1. Is the input seal supposed to face in with the spring on the outside? Also what's the best way to get it out with the shaft in it?



2. Why are there 2 different size tailshaft bushings and what is the part number and where can I find the larger one?
I have the Timken #5208 Seal and Bushing kit but it's too small.

I took an old screwdriver, heated it up with the torch and put a small 90 on it. Hold with channel locks, and beat on the channel locks with a hammer.

I destroyed like 10 paint can openers before trying that. Just try not to beat up the shaft.

I have a bent screwdriver like this for similar purposes.

It was a broken craftsman before I got my hands on it, I ground it down to a flat blade and bent it with a torch like Adam described.

I'm tempted to take it back to Sears and ask for a replacement, just to catch the counter boy's reaction.

I vaguely recall a post that talked about the correct bushing, but I have no idea where it is. I had a problem like that so I went SYE. j/k.

Barring any additional input, I'd think the spring goes on the inside. Pretty sure all I've removed, the spring was on the inside. I've been told the outer lip seal is to keep junk away from the inner seal, not to keep fluid in or out. Makes one wonder why an input would need a double lip seal then.

Spring faces outside. a seal puller is probably too big to get in there. One of those booger hooker tools would help.

I got the new larger bushing in today. Fits just as it should. I used p/n: 15665313

As far as the input seal, I got the original out and found out its a double lip seal with a spring on both sides. My seal kit doesn't have a seal like that. It does have 2 single lip seals that fit it and the others don't fit over the shaft. Should I install both single lip seals to make a double? Sounds screwy but combined are the same width as the original.

 

[Deuling]

I would. That is the single most important seal on the unit in my opinion. And the most time consuming to change...

And that input seal must not be original. That came out way too easy.

Mine came out in many pieces.

 

[Chevy305]

Ya the best I can tell it's been a part before. Bought it used from a fellow CK5er several years ago after the original one ran low on fluid and half grenaded

 

[Deuling]

That's nice.

I spent like 3 hours trying to get that seal out.

THanks for the info on the bushing.

I think I read somewhere that the smaller bushing is for 27 spline units and bigger is for 32. I can't say for the 27 spline but I know my 32 spline is the larger bushing.

 

[Deuling]

Why must there be different splines. So much extra work.

 

[Chevy305]

Ya it's frustrating. But wait, aren't the output splines the same? It's just the input splines that are different no?

Yeah output is the same across the board. Just input differences.








32 spline ftw.

So why are there different bushings?

 

[wetoolowdingbangow]

That timken 5208 refers to the output seal for a th400...maybe there was an oops.

Ya but it's listed for the 208 and 241 outputs according to all the parts stores.

Had to do that with the seal on my 205, kit didn't come with the right seal either, so just installed two seals. Has held up fine for years.

That's good to hear

 

[Chevy305]

Re-installed with the 2 single seals and no leaks. In fact no leaks at all even on the new slip yoke.
