Rebuilding the D300: what is this???

I'm new to the Dana case (this is a 1980 Jeep D300, shorter version) and compared to rebuilding an NP241, this is brutal! LOL OK, so I haven't got a manual YET (I will soon though) I did try a bit, blind. Here's where I ran into a problem. I got the rear yoke off but can't slide off the aluminum housing??? I think it's the speedo gear there, and it may be holding me up???? Here's a pic:



How would I get that off???? I can't get a socket on that sensor because it's set so low in that housing. Here's a "bad" closeup of the sensor:



Any help you guys can give me would be great. Thanks in advance [img]images/graemlins/grin.gif[/img]

Cheers,
Steve

Re: Rebuilding the D300: what is this???

Yeah, that's the speedo gear. And no, that shouldn't hold you up. It's been awhile, but I think the rear housing just needs a few taps with a deadblow and it will come out.
.....Ok, so I got the FSM and checked....Instructions as follows:
1. Remove speedo driven gear sleeve and gear.
2. Remove output yoke.
3. Remove bearing cap-to-case bolts.
4. Remove bearing cap. Note: the cap has been coated with
sealant. Use a putty knife to break the seal and loosten the
cap.
5. Remove the shims and the speedo drive gear.

That's pretty much what I was saying. [img]images/graemlins/tongue.gif[/img]

The speedo gear retainer can be removed with a pliers as long as you wrap the threads with a piece of leather, like an old belt, so the threads won't be damaged. Or, go get a cheapie socket and grind it down.

Re: Rebuilding the D300: what is this???

The output bearing is holding it in. Take the bolts out and forget about the speedo. Pull on the alum housing and just a soft face hammer and hit the output shaft in. Be careful of where the shims fall or stay stuck, for the outer bearing. Once you have the tailcone off. Pop the seal out and then the bearing will fall out. When you put it back together, put the tailcone on first, then use a pieceof pipe or deep socket to put the bearing on after the tailcone is bolted down. Put your new seal in and your good to go.

Re: Rebuilding the D300: what is this???

That is a great article (added to my bookmarks) and it is the long output housing with the speedo gear that I am used to dealing with. I just wasn't sure about how that speedo gear fits in the short output housing it looks different.

Pontiac58 goes on to say that the bearing is holding things together and a few bumps will get it apart.

Thanks for the article.
