1984 Scrambler Rebuild

[Big_Mark]

Naw I didn't roll over THERE lol... I did roll other places though, that's how I learned the limits of that Old Jeep!

 

P.S. that was me in 2009

Now that I have everything cleaned up and all the bearings and seals pulled - it’s time to start rebuilding. I now press on the inner pinion bearing and slinger on the new pinion ->

 

Before pressing the new gear onto the new carrier I brake cleaned all the holes in the ring gear and ring gear bolts. Now on the press to seat the ring gear on. Very important to add red locktite to the bolts before torquing them to 60 foot pounds ->

Now ready for the set up process->

 

The old carrier has shims behind the carrier bearings for proper backlash. The bearings need to be removed to get them out. They need to be kept together (left and right). This just gives you a starting point for the setup and not going at it from scratch. We have a special bearing puller for this, but on occasion they break when removing even with using this. We just use a Dremel to cut the bearings off if that happens ->
 

The bearings off and the shims out (I use bailing wire to keep the right side separated ->

 

We use slip fit bearings for setup. They will be taken off and on a lot during the set up, so we don’t want to damage the flight bearings during initial set up. After a bit of +/- shims we get an acceptable pattern ->
We also have a slip fit race (bearing cup) to help getting the pinion depth correct. Now it’s on to setting up pinion preload.  As I said earlier, this axle does not use a crush sleeve. It uses pinion preload shims to get the correct (15 inch pounds we set ours at) preload. After a slow process (we try not to use new shim kits because they are $$$) using unused shims until we get that magic number. When we are ready for the final pinion set you first need to drive in the inner flight bearing cup. Make sure all the shims behind the race do not fall out when doing this. Because of this inner baffle ->
the pinion shims need to be put in before the bearing and pinion seal are installed. I use a tiny bit of grease to keep the shims together->

 

Then I place the shim pack inside on the baffle->

 

Pop the outer pinion bearing in and the oil slinger on top->

 

and install the pinion seal * don’t forget to oil the seal* ->

😁 I can't imagine a roll over! Glad you weren’t hurt or it stopped you from continuing to wheel. Looks like a lot of fun though.

My Cj8 was a daily driver / weekend wheeler for about 10 years, then I got tired of wheeling Sat, running to Shucks (now O'Rielly's) on Sundays to fix the broke stuff so I can get to work on Monday so little by little it turned into the thing it was. Most mods were designed to run trails a Reiter Trails (aka Reiter Pit) in Goldbar WA.

Dana 60s f/r Detroit locker in front, spool rear, 6:17:1, Blueprinted and balance 5.0 EFI, T-18, Dana 300 with independent f/r hi low for digging around stuff!

BTW rolls were mostly flops, were always at low speeds so no worries there.

 

I do not expect to turn my Manche into a thing like that, but I would like to add a few things!

[Drahcir495]

I ran into the same problem with my Cherokee. It would break down all the time and I had no back up car. It eventually got everything new, but by that time I was over it and wanted my reliable MJ back. I will have the Scrambler as a weekend toy. I don’t plan on any hard wheeling though. Until the CJ8 is up and running I can’t risk breaking down. 

[Drahcir495]

Now that the carrier is set up, I can take care of the spindle bearings that fell apart. Here is what I started with ->

All the roller bearings fell out of both sides.  First step was to pull out the bearings->
 

 

As soon as that was done I packed the bearings with grease. Putting in the new bearings->

 

Used an aluminum bearing installation tooll but I know many other things would work ->

 

Once it was flush, I used an impact socket the same size of the bearing to knock it in a little deeper into the spindle.

I finally got around to towing the CJ8 up to the new place.Took the 4 hour drive to its new home. I was following the tow truck the last 30 minutes watching the license plate flapping in the wind. It was hanging on by only one bolt. I figured if it hadn’t flow off in the last 3.5 hours, it probably wasn’t going too . In the new spot in the garage->

Looks great in its new habitat!

[89 MJ]

What a cool looking rig! I’d love to find a Scrambler someday. 

[JZLAJeep]

Love it and love the full length soft top. We came across a CJ-8 with full hard top this summer in northern Idaho. 

 

[Drahcir495]

 New habitat.

 

89 MJ - I don’t think I could afford a Scrambler at what they are going for these days. 
 

JZLAJeep thanks. There was a time when I was looking for one, but would be a challenge to get it off and on. We like to roll topless down here. So cool to see one though 

[Drahcir495]

I have had these step plates since 2002! just never put them on ->

 

I had them powder coated soon after I got them. I put them on the nerf bar today -> 

[Drahcir495]

The final drivetrain piece is in my possession. It’s been so long since I’ve worked on a CJ I’m not sure it’s called a D300 Transfercase.

 

 

If I can get so free time here, it probably won’t be long until it’s running. The engine has been sitting for 25+ years. I’ve been manually turning it over, but it seems good 

[watchamakalit]

D300 for sure. Feed her some 80/90weight and got for its. Great case.

Excellent - thank you

[Drahcir495]

 I can’t get my Dana 300 Transfercase to mount up to my T19 transmission. This is a different xfercase and the other one went in no problem - this is hitting the side of the transmission ->

 

  

 

[neohic]

Are you sure thats a T19? There are a few Dana 300 shifter linkage combinations also. Mixing and matching sometimes requires making some clearance. 

[Drahcir495]

Definitely a T19 with synchronized first gear. It took me a while to find one. That’s not good news. I sold the other one because it had two. What to do now?

[Drahcir495]

I got it in and it does have a bit of clearance but will the bolt that holds the shifter in is too long? I forgot, it’s been 12+ years since I took it apart.

Thats the joy of CJs! Mixing and matching parts while also cutting and modifying! 

[Drahcir495]

 Yes!

Real jeeps are built not bought. Its truly funner that way.
