International Harvester 727

I finally found an International Travelall with the AMC engine a while back. The guy even delivered it to me on a flat-bed for free and had his employees unload it for me, just to get it off his property! I only wanted the 401, but it also has a chrysler 727 automatic in it and a semi-float five lug Dana 60 axle, but it's two wheel drive. I also have a 727 from a four wheel drive scout. I want to combine the two tranmissions and use the case with the AMC engine pattern with the four wheel drive tailshaft and factory adapter for the transfer case from the scout. Is anyone running a 727 in their CJ? Are there any clearance issues with the front driveshaft and the transmission pan with this setup in a CJ with a widetrack front? It seems like if it cleared in the Scout, it should clear in the CJ but it seems like I have heard of a clearance issue before.
 

i think they are kinda long for a cj5, but you might have a 7. on pirate there are several threads on pirate about the front shaft clearence, and i beleive that you have to notch the pan somewhat for the shaft to clear...
 
I thought the IH bellhousing pattern was different from AMC, have you confirmed it will work?

Have you measured the width of the D60 from WMS to WMS (wheel mounting surface)?

Bounty__Hunter,
i think he is gonna take the internals from one and switch em inot the one w/ the 401 :?
 

That's what I want to do. I have the two wheel drive transmission with the AMC engine boltpattern and I want to take the output shaft and adapter from a 4wd ScoutII transmission and convert it.

The best I can remember, the axle is 62" or 63" wide. 30 spline shafts and 5x5.5 wheel bolt pattern. It's been awhile since I measured it though so I might be wrong.
 
That's cool that it had a 60. The Scout 44 rear ends suck. I bet that the shafts from the 44 and 60 are the same in the Scout and Travelall. Both 30 spline 5 on 5.5. The 44 housing tubes are ultra thin. I bent two of them (the second had a truss on it). They couldn't hang with the 360 much less a 401. The Scout 44 front ends are decent though.
 
I like the ScoutII 44 rear, its got a strong center section and it's fairly lightweight. The tubes are stronger than a Jeep model 20's tubes. It's an okay axle for an easy upgrade.
 
If you say so.
Easy is never better. I would keep the AMC 20 before I put the Scout 44 in there. Trust me.
You're right the centers are fine. It's the tubes that are weak. A friend of mine bent one of his tubes putting it on a trailer with a chain binder.
If you weld to it you better take it slow and let it cool or you can kiss that housing goodbye.
 

Re: Swap a carter w/ a carter? What was i thinking?

Sorry, I forgot. REAL Jeeps have 1 ton axles and Chevy 350s(preferably a vortec).

I've even got a chrome(oh no!) cover on mine. I guess my rear axle REALLY sucks, huh?
 
Chrome won't get you home!
No...I've got a 360. That's 10 better than a 350.

I wasn't trying to hurt your feelings, merely stating that you would be better off with that 60 rear. Looking back it would have been a lot less expensive for me to build one rock solid, bombproof rear end than the 3 that weren't up for the challenge.
If you go with the Scout axles under that 401 you will quickly see what I'm talking about. Oh, and by the way the chromoly shafts for scout axles are expensive and spare OEM's aren't readily available (at least around here). Moser wants 6 weeks to make one and you have to send them one for measuring.
 
Christmas List

I understand what you're saying. No hurt feelings here. I've got some experience with it and I haven't seen the weakness, others will most definately have different experiences. Down the road from me in a town called Hubert,NC there is a guy named Bob who owns a four wheel drive shop called Big Wheel. A buddy was planning to put ScoutII axles in his CJ, and when I recommended something a little heavier he carried me to see Bob. Bob has a Scrambler with a 496ci stroked big block Chevrolet, 44" boggers and a set of ScoutII axles. It could probably be considered a show vehicle, but he doesn't mind turning it loose every once in a while and doing a burnout or two. No problems YET(he WILL). But since my buddy installed his a couple of years ago several others have done the same around here and everyone loves them. We don't have rocks, just mud and sand and stoplights. If you want to go fast, you've got to run the lightest components you can and still maintain reliability. If the 44 proves to be unreliable, I might just follow your recommendations and use the 60.

By the way, the 401 is being saved for something else. My little 304 scares the hell out of me enough for right now.
 

Might be some special tail shafts (length, diameter, spline count) for the internationals. But Dodge just made two lengths of output shaft, that I´ve encountered, and one output shaft diameter and spline count (in trucks). The only difference in the short two wheel shaft and the short 4X shaft is the, speedo output on the 2X shaft tail housing and the speedo gear drive on the output shaft. The 4X adaptor will bolt up in place of the short 2X tail piece. I´ve only run across one spline count in the 727, but I messed mostly with vans and trucks.
There are always some odd pieces manufactured, but I´d check about just swapping over the 4X cast iron adaptor onto the 2X case. Spline count, diameter and shaft length, shouldn´t be too hard to measure. Most of the truck/van applications, had the short tail shaft, because it was stronger than the long.
 
MudderChuck-- Thanks for the info, I wasn't aware of that. Good info to have. Unfortunately, I went out behind the shop last night and pulled the tarp off of it....I didn't even bother measuring, it's loooong.
 

I live in Wilmington. You guys have some pretty good fourwheeling spots in Raleigh, I hear.
 
If I ever get a chance to finish the bodywork and put my CJ back together, I want to get up that way and play in some of that Raleigh mud I keep hearing about. I really built this Jeep for street racing and drag racing on the beach, so the gearing and cam timing are all wrong for any decent four wheeling other than wide open blasts. I'm regretting it now. I think I might just finish it and sell it. Either way it looks like it will be awhile before I'll be planning any fourwheeling trips. If I should happen to make it up there anytime soon, I'd like to get up with you and let you show me some good spots.
