Correct. I believe it has something to do with the shift pattern. Direct is always where "4th gear" would be, so instead of shifting in a horseshoe, it shifts in an H. Dont quote me on that, but that's how I understood it.

 

Ok this may sound like a rookie thing to say but I have been under the impression that the shift bolts on to the top of the tranny and thats where it sits, is that not true, in other words can I mount the shifter, and mount the tranny and control it with linkage?

Cause I have been pondering how the hell I am going to shift my transfer case if its way back behind the brownie!

I have a feeling I have been wrong all this time.

The fifth and sixth pictures in the first post show how the t/c shifter is mounted. All I can say is, you're going to have some interesting architecture going on down there with all the linkages.

 

Ok so, transfer cases have linkage and transmissions are top mounted? My other thought was swap my TC for a 1356 electronic shift. Although I don't like that idea as much.

Anyone know the torque spec for the input and output yokes on a spicer 6041?

Looks like 375lb-ft of engine torque.

 

Hello,both the input and output yoke nuts get 350 to 400 ftlbs.

 

Ok So just got off the phone with a guy that has a diesel 2wd zf5 about an hour from me. I am seriously considering going down to pick it up this weekend as part of my drivetrain project.

I am feeling alittle uneasy though because I have not finished my research. As of now my thought is this:
A fully divorced setup,
2wd zf5 to brownie to a divorced transfer case, maybe a np205, I don't know a lot about transfer cases yet.

The part that really hangs me up is how am I going to make all the shift linkage work? People must be doing it somehow. Also I need to find a tcase with a mechanical speedo port, divorced, I was thinking an electric shift case if I can find it. Also how will I get a speedo cable that long?

Thoughts?

Speedometer shops will make you a cable that is very long. The other thing I have heard, but not done myself, it a second cable that screws into the first. The two cables together make one long cable.

Measure the length of the ZF, Brownie, and transfer case. How long is your wheel base? Are you comfortable with a pillow block bearing in your drive shaft to the front axle?

 

What's that?
Devin

 

A pillow block bearing is a bearing with a mounting built around it. These are used when you have to go to a two piece front drive shaft. Think the center carrier bearing in a regular rear drive shaft, but without the rubber between the mounting and the bearing. I think pillow block bearings are used instead of carrier bearings due to the amount of movement of a front axle relative to the drive shaft. A rear axle is going to move around less from the drive shaft point of view since the drive shaft is going to the center of the rear axle.

Google search for pillow block bearing: https://www.google.com/search?client...block+bearing+
If you are interested in this, by all means find someone who is familiar with using these in a rig, I have no experience in this.

 

If I can't find a TC with a mechanical speedo, does such a device exist, where I can put it behind the TC and plug into a mechanical speedo cable?

Devin

 

Not that I am aware of.

I am looking at a similar issue. Since the posting I did earlier I have acquired a smaller auxiliary transmission to some day install into my 3/4 ton pickup. While the smaller transmission looks way easier to package, it lacks a speedometer drive. My planned solution is actually pretty simple since I only will have two gears behind the speedometer drive in the main transmission. I purchased a NOS two speed speedometer adapter originally intended for trucks with two speed rear axles. Since the gear ratio of the truck two speed axle is about the same as the gear ratio of my auxiliary transmission.

If you are running an electronic speedometer it is possible you could get a programmable signal modifier and have it change the signal sent to your speedometer based on your selection. I have heard of these as a permanent adjustment, not as a select on the fly arrangement, but something to look into possibly.

Oh that is useful! That really opens up some options, thanks.
