Xfer cases...

[limpingalong]

This is a follow on to my previous thread...

I am still trying to figure out how to setup the new rig...working on the xfer case issue.

Can I bolt a 228 xfer case (out of a waggy) up to my existing T5 tranny?

Also, what are the vaccumn lines that come off the 228 case for? Would I need them or can I just plug them?

Thanks,
CHip

Paul - thanks for the reply but that still leaves some questions unanswered. From reading the page, it is more about replacing the 228 with a 208. I do get the the 228 sucks though.

It sounds like what I thought were vaccumn lines may actually be ATF lines to go to the cooler...is this correct?

Question still remains, can I bolt a 228 xfer case (out of a waggy) up to my existing T5 tranny?

Thanks,

Yes the 228 should bolt up to it. It has the circular bolt pattern and 23 spline it is the same as the Dana 300. Since the 208 is bolt in swap I would assume that makes the 228 as well

But from reading that article it appears the 228 Uses Fluid from the tranny to lubricate it. Which may be a problem behind the t-5.

I have a T-18 and np208 but they were out of a 4wd Ford Truck. It is a driverside drop set up. But I dont know if it would be to long for a CJ. I would take $500 for both the tranny and t-case if you were interested.

It was bolted upto a 258 in a YJ, But a rear axle was never put in the jeep before I got it and pulled it all apart.

At the bottom of the article there were a few corrections. One of them said that the Tcase DOES NOT get lubricated from the Xmission, it has it's own fill and drain plugs.

Which now still leaves the question of the two lines that leave the 228. Are the vaccumn or liquid. Can I cap them or do they need to go somewhere?

Another question - how did the waggy's ('85) shift between 2H, 4 H and L?

Was it vaccumn driven or done with a shifter on the floor?

I just found this

SelecTrac is what Jeep labeled the vehicles with NP228 and NP229 transfer cases (probably others in the other models?) which shift gears by way of a vacuum switch under the dash. These systems can operate in 2wd mode or full-time 4wd mode (i.e: drive on dry pavement in 4wd). The NP228 (1986) has no limited slip; the NP229 uses a limited slip similar to the NP219.

I would assume that means it shifted via vacuum switch. Which would also be the lines on the t-case?
