Cj10a

I just purchased a Jeep CJ10A aircraft tug and do not plan on using the Dana 70 rear axle. I wanted to know what its worth, or if its worth enough to trade for 2 axles. Also if I leave it 2wd only what is a good ratio for fuel mileage.

CJ10a

It has a Nissan 6 cyl. diesel and I am hoping to get better than 22-24mpg that I get out of my S-10. So yes if I can get some extra mileage I will drive it daily.

No I didnt copy any pics from the auction.

When the pollution controls came in they went with an OD tranny and 3.31 gears in a lot of CJ7's. I and others are getting a nice 20+ mpg with our 258's and that setup. I run 33's and forget about 5th because it dros me to 1750 rpm at 65 mph which lugs and costs about 5 mpg.

I've got a tug, also. I'm planning a future project with it. I've never gotten it running, yet, and don't even have key.

The 70 rear is worth something to a limited group out there. Try some of the groups/boards with M715s. Full size Jeep axles will swap in fairly easily.

Alright guys, I got my CJ10A home today and I need some help with some parts. I need to know how or where to find an alternator, vaccum pump?, dipstick, and glow plugs for starters. Anybody have a manual or wiring schematic on these things?

Unfortunately you may be hard-pressed finding parts for that Nissan I6 diesel. I've heard many people complain due to the lack of parts sources.

The big thing about those airplane tugs is that they have a large amount of weight on the rear to balance it or whatever, so getting rid of that will get rid of a majority of its weight, if it hasn't already been removed. This should help your gas mileage greatly. I would just go with a Dana 44 or Dana 60 rear as long as you're not doing anything extreme. I think most of those came with the TF727, so you're only going to have a 1:1 final drive gear. If you gear it right you should be able to get pretty decent gas mileage out of that diesel. The biggie is that the transfer case is locked into low range, but with the right parts you can make it selectable again. Most of those things couldn't do better than 30ish mph, but with high range I would expect much better.

What engine is it, the SD33 or SD33T? You should be able to get parts for it at a Nissan forklift dealer, or a marina/boatyard that deals primarily with commercial-type boats. Try the IH Scout parts places too, as they used this engine from 76-80.

It has an SD33. The "T" is for turbo, they were used in IH Scout IIs.

I went searching last night and have located glow plugs for the SD25 motor and I think that they will fit in the SD33, downside is they are $14.99/ea. Also I am missing the a few key parts.

I am debating switching out the axles, or regearing to a more fuel friendly ratio. Any advise or pics on how to make the transfer case selectable would be appreciated.

The weight will be the first to go.

It may not be a bad idea to keep the stock axle in there. I've heard that some of those used the NP198 and some may have used the Dana 20. Both would be locked in low range with the front output "disabled" with a plate. I would imagine it may be easier to just swap out the transfer case for one of the same type that does have a front output and is selectable, or you can swap parts. Or if you won't be switching back and forth you can pop it open and just move the forks so that it's in high range instead of low range and then pop the cover back on.

I've also heard different things on the rear Dana 70. I've heard people say the gear ratio is anything from 3.73 to 4.88. Is there an ID tag on the rear differential attached to one of the cover bolts? This would clue you in as to what gear ratio it runs. I've heard some say that they came with Power-loks, a very good LSD, but I'm not so sure how true that is either. Obviously with only a 1:1 3rd on the TF727 4.88 gears will be a little steep, but 3.73 gears would be quite nice.

Here's some more info from an owner that bought a few of them...

The rear 70's are supposed to 4.88 with a GuvLock posi unit. The Transfer case is supposed to be a 198 (single speed) or a 208 (locked in low). A Jeep 208 out a Waggy is a good choice, it's a bolt-in and a strong unit.

I've never heard of a Dana 20 t/c in one of these.

Went and gave it a more thorough look today. DS floor needs replacing, and maybe the panel under the DS door.

Also still cant decide whether to swap axles or regear. Found Motive Gear brand gears for Dana 70 axle and could go as low as 3.54:1 for $180. How hard is it to switch gears and could I keep the locker.
