i searched but couldn't find the pics/writeup for the tf727/d300 combo...

could someone show me some pics or point me in the direction of a writeup? i need to know if the front shaft will hit the tranny pan and if the 727 bolts are clocked at an odd angle...

thanks

I think that this was a factory combination on the 1980 IH Scout II's.

That probably dosen't help much. ;)

Can't clock a IH, because it is a texas pattern!

How far are you needing to go? Are you use ing one of these?

There is not enough room to run a DC shaft in the stock location, but some guys have trimed the 727's oil pan and made them fit .

This is a Jeep 727 and a Jeep 300. It works. It fits as long as you use a small front driveshaft, and at least 3 inches of lift. That is what I am running in my CJ with a GW 360. When I was running the stock 30, the driveshaft would occasionally brush the tranny pan under full stuff on the passengar side. Now with my 60's, the pinion is moved to the side enough that it clears with no problem. You can also clock the 300 with clocking ring and move the driveshaft up and out.

In a stock CJ application i.e. lift and front D30, yes it will hit the pan. With 4" suspension lift and D30 yes it will still hit the pan when the passengers side is stuffed. No room for a CV joint at the Tcase. And the D300 will be clocked at the same angle as it is in a stock CJ application.

You didn't say the application of the 727. I will assume it's out of a Wagoneer. If so it's a bolt together. If not you need the output shaft and and tail housing from this application to get the D300 bolted up.

You are always going to have clearance issues at the pan with anything other than a full size/width front axle or custom built housing. You need to get the pinion outboard more than it is. Even the Wagoneer front axle conversions leave little room next to the pan. I've put several of these together and nothing more than the stock CJ dimension (od) driveshaft will clear. For the most part you can forget it with a stock D30 front, but...

You can solve the whole clearance issue by running a two piece driveline. This is how I made it work in my rig. 440 / 727 / 300. It works sweet. The carrier bearing is mounted to the skid pan right next to the widest part of the tranny pan. (next to the dipstick tube) Then it angles down to the pinion. I've "never" hit the front driveline. It parallels the leaf spring and is protected by the rear shackle.

Hope that helps. :usa:

Got any pic's? I'd love to see what your talking about!

--D

this is on a grand wagoneer...

i'm going to be bolting up the D300 to the stock 360/727 combo, but it's going to be clocked 180 degrees (unless i can find a high pinion pass. drop 44 that is worth swapping in).

so i guess you could say that i'll be using waggy axles and a waggy tranny ;)

my options are either at least a 3" lift, a skinny front shaft, or a bit of trim off of the 727??? skinny front shaft (1.5"?) sounds best, except that i will be running 36s; will a 1.5" shaft hold up to 250 hp/350 ft lbs and 36" tires with 4.56s?

trimming the pan... 727s are cheap, but i'd still rather not mess up. so how difficult would this be, and how much would i need to trim off? are custom gaskets/welding/fabrication involved?

3" lift... maybe in the form of an SOA (if i can get ahold of a worthy front axle) or added leaves.

thank you

Can't get you any pics. I'm in Turkey and the Jeep is in the shop at home in Cheyenne. Just look at the rear driveline in a 2wd long bed full size truck. Then use your imagination... Obviously it's a lot shorter.

WillyPete- If you are using a D300 in a grand waggy you are golden. The driveshaft fit problem only occurs with the D300 in the right position, i.e. with the front driveshaft down the passenger side of the tranny. Theres alot more room running the driveshaft down the drivers side. Have done this swap as well. Not with a D300 I used a NP 241, persoanally I wouldn't run a D300 upside down, but to each his own.

As for a passenger side High pinion 44, not going to happen from a factory application. Although you could swap in a 74-80 Waggy front to keep the D300 oriented the right way. It's a bolt in.

Another option you may want to consider is the NP 241 T case. By the time you buy the kit to convert the D300 to inverted use you could pick up a 241 easy. Only "drawback" here is you really need an air leaker up front. Something to think about. I've done this swap as well. The 241 is a great case. From a DODGE application you even get the fixed output shaft with yoke. Its a big unit though.

What's wrong with the stock Tcase. If its a full time unit, go back a few years to the early 80's and find a NP 208. It's a good case. Bolt in swap same low range. Just run an air leaker in the front.

i'm not sure if you meant that a HP44 was not jeep stock, or stock period... but i'm considering swapping in a HP44 from a ford or chevy... i just need to hit the junkyards and see what they have. i don't know if chevy ever used a HP44, but i know most of their axles are pass drop, and i know ford used HP44s occasionally, but i don't know if they were driver's or passenger drop :laughing::confused::D


reasons for a flipped 300 instead of a 208:

stronger case (cast iron, gear driven)
dual lever capability
coolness factor

why wouldn't you run a D300 upside down? will it have oiling problems? i'll be doing all this myself, without a kit... that's another reason i'm doing this particular swap, just to see if it can be done sans kit.

thank you :)

btt

Do a search on the flipped D300. Ther was a bunch of discussion on here a couple months ago with more specifics.

No HP44 from Jeep, Ford is your only source. To my recolection there never was one offered in a pass side app. The F150 or 78-79 Bronco front end would be sweet under a Grand Waggy. Give you the Cherokee Cheif look. The cheif fenders will bolt on as well.

I'd still think about the NP 241. 3/4 and 1 ton parts. You can't hurt it, plus even better low range. 2.72:1. Have to do some research but I remember seeing a 2Lo option avail from somebody for this case??? Kind of out of touch over here...

Coolness factor??? A Grand Waggy project is cool enough. Don't over complicate it.
