D300 ceased?

[Jeff Kavanagh]

Hello everyone.
I am very new to the CJ7 world and also the world of fixing vehicles.
I figured a CJ7 might be a fun place to start.

I know I will be asking a lot of dumb questions which I will apologize ahead of time for now.

At the moment I will be working on getting a 85' CJ7 which I acquired just running and then go from there.

Right now it is stuck in 4 wheel drive and the shifter handle will not move at all. It is locked or ceased in place. The Transfer Case is a Dana 300 and I am thinking it will likely need to be stripped down? That's my best guess anyway.
Looking at the Transmission (5 speed manual - don't know what kind yet) I am seeing that the back end of the Transmission is held up by the skid plate? Is this correct? The four bolts on the frame and two in the center on the Transmission .

I guess I am just kind of asking, where do I start?
I have been looking for any kind of YouTube videos or info on this topic but haven't been able to find anything.

Any advice and help would be very much appreciated.

Thanks Jeff

I'm not sure what attempts you have made or how long this problem has been going on. By "shifter" I presume you're talking about the 4 wheel drive. Have you backed the jeep up about 20 or 30 feet and tried to place it in 2 high? Have you attempted to shift into 2 high while backing up? Sometimes this works.

:ww:

Have you ck'd the oil level of the t'case?
Have you tried backing up and disengaging the t'case?

Should be 6 bolts on the skid plate.
You will need to put a jack of some sorts under the bell housing to support the engine when you remove the skid plate.
Best to pull the tranny and t'case as a unit.
Your tranny is a Borg-Warner T-5 built for AMC-Jeep.

WHATROAD the jeep isn't running yet so no I have not made that attempt.
It has been sitting in a shed for the past three to four years.
The front hubs were locked and I noticed when it was towed that it was in four wheel.
The shifter will not move at all.

Lumpy Grits that is what I was thinking I would need to do.
No I haven't check the oil level yet.

Thank-you for the replies guys.

I might have to pull everything out.
At this point I am not even sure if the engine is any good. I tried to turn it over by hand but I could hardly get it to move.

My friend gave me two CJ7 's he had. Just looking for a good home for them.
The one I have referred to now has a very good body and frame. Hardly any rust. The other jeep, the frame and body are rusted out but it was on the road last year. It's a 79' V8 with a 4 speed manual.

I am thinking worse case scenario, I might have to swap out the straight 6 for the V8 so everything will have to come out anyway.
I pulled the plugs and put some diesel in to see if that lubricates and frees things. Just charging the battery now for it.

I think I have my work cut out for me, lol

Since the Jeep isn't running the best advice I can give is -

1) Don't force the Transfer Case linkage, you don't want to bend anything.
2) Wait until you get the CJ running so you can move it by it's own power. As was stated the best way to get a stuck Transfer Case unstuck is by slowly move the Jeep forward and then backward while pushing on the 4wd shifter.
3) If you do get it to shift change the lube.
4) As a last resort pull the Transfer Case .

Have you ck'd the fluid levels in this engine?
Try a FRESH charged & known good battery. How fresh is the fuel in this Jeep's tank?

A free jeep and a donor jeep! Some guys have all the luck. Welcome aboard buddy. I'd wish you more luck but you seem to have that commodity sewn up

 

[Jeff Kavanagh]

CJ thanks for that info. That's what I will do then.

The gas tank I am going to replace so I bought some fuel line and am just going to run it to a gerry can of fresh gas.
Put some in the carb and then try to see if it will go.

That's what the plan is I think so far anyway.

 

[Jeff Kavanagh]

Lumpy Grits yes all the fluid levels are good in it.

Before you get to deep into removing the Transfer Case make sure you actually need to. Remove the plates covering the stick and the Transfer Case boots. Take a good look at your Transfer Case shift linkage. Determine that it is clean of obstructions, then hit it with some sort of penetrating oil. The mechanism is a simple affair, but complicated at the same time. To be in 2wd high the left hand shift rail needs to be all the way to the rear and the right needs to be one notch forward.

Jeff, one thing I noticed is that you are trying to figure out what exactly you have. I would like to suggest you start by looking through our CJ database forum. It was created by some great members of this site just for the purpose of helping with exactly where you are now.

-->> - Jeep CJ Comprehensive Database at Jeep-CJ.com

I would also suggest you check out these threads next.

Good luck!

I would suggest buying a factory service manual. You can find them on ebay. You can find manuals online as well.

Thank-you very much everyone.

Even though the Jeep is not running, you could simply jack up one of the front/rear wheels which will tell you if the drivetrain is bound up.
The wheel that's raised of the ground will "unwind" or turn backwards.
Just something simple to try before you start tearing into things.

There are other ways of making the Dana 300 shift smoothly, but try this first.

Yup that is the case. When the tow truck driver picked it up for me he first picked up the front to pull it to a better spot to put the back wheels in a carriage and as soon as he did that, the back wheels were locked and one went backward as the other went forward.
