Transfer leak at speedo cable (1 Viewer)

[Ripley]

A couple pictures of the seal inside the speedometer drive housing, and the speedometer drive gear service kit contents and part number. This is a 6x18 service kit.

In the 33403-69065 speedometer driven gear service kit you get:

One speedometer drive gear housing external o-ring.

One speedometer drive gear housing bushing.

One speedometer drive gear housing internal o-ring.

One speedometer driven gear, 6x18.

Anyone know where/what the white felt is for? I didn't see it in previous descriptions.....maybe I missed it. I have one in my rebuild kit, but didn't find any reference. Thx. BTW, dental tool/hobby tool works great for getting the inside O-ring out.

On some earlier applications, the felt was used at the end of the speedometer cable where it seats to the drive housing.....

It goes in here and the cable goes through it, IIRC:

I see now...it makes sense. Thx.

hi my speedo cable is leaking at the t-casse and this thread answers my question about what needs to be changed to correct it(o-rings), but can you tell me the purpose of the felt or is it just a dust seal? does anyone know the size or buna-n o-rings cross reference p/n so i can get them locally and today? btw its for a '67 fj40 3 speed t-case.
thanks

I do believe the felt is a dust seal. Not sure what year my transfer case is, but the Speedo assembly in mine doesn't have a space for the felt. Neither does the shift linkage for the 4WD.

Thanks for the help!

The first picture shows the speedometer drive housing in the rear seal housing of the transfer case and the tab that retains it. The second picture shows the speedometer drive gear and bushing being removed from the speedometer drive housing. The third picture shows the speedometer drive bushing being removed from the speedometer drive housing.

Is the retaining tab a separate piece from the housing? When I took off the 12 mm bolt, my tab just fell to the ground. How does it retain the housing as a separate piece? I thought it was part of the housing and that mine had broken off.

Never mind. Duh moment!

This the best info thread on these speedo seals, thanks @Poser!

The little o-ring fits snugly on my drive gear shaft, so it will spin with it as best I can tell. Is it then suppose to spin in that internal groove in the drive gear housing?

 

[middlecalf]

Disregard previous post @Poser, finally figured it out & found the old o-ring in the slot. New one in, a bit more resistance but I suspect that will subside.

Hey yall, I picked up this seal kit from city racer and it's slightly different than the one that came out of my truck. All I really need to know is which way to install the inner seal, it has a little compression spring on one end. I assume the spring faces out towards the cable but I home someone has some info

@Dex43

What seal kit? What truck? What year? Is it stock? Has it been "upgraded"?

Thank the automotive gods for forums and for mud, that is what I needed!

PS I meant to upload a picture, my bad.

FWIW:
A church key also works at getting the old seal out.

My goodness. There's a SST for this job?

 

[ToyotaMatt]

thats a Dynamic thing too in fact !

 

[Dex43]

This was found on the ground, does it go in after the speedo cable seal?
