88 tcase on 98 M50d?

[Denisefwd93]

Found an 88 Being parted outThought I'd ask here first, save myself driving a couple hours

Pretty sure the T-case is interchangeable. An 88 will likely have a 1350 or 1350e transfer case, a newer RBV could have a 1350 series or 1354 series. Both use the same bolt pattern to attach to the transmission. Outputs can be different though, I've seen both flange and yoke outputs, but those can be changed. 1354 series are a little stronger than the 1350, but I'm not sure how critical it really is, I'm running a 1350 case on my choptop with 35's. The one issue you may have if you're going with a manual transfer case is the transfer case shift linkage may not work with the m5od trans.

There's a bunch of information (probably enough to confuse you, haha) here: http://www.therangerstation.com/tech_library/TransferCases.shtml

I keep reading and reading all the tech pages. All things not being equa, l I'm guessing it's best in the short term to stay with the 1354 that's on my A4LD and just bolt it onto the newer M5OD

I'll have a 98 electric T-case coming off the newer M50d. (no speedo gear)

what and how do the manual and electric T -cases relate to the transmissions anyway?

OOPS! it's in a 1990! my bad.

The electric T-cases are considered by many to be less preferable simply because it's relatively common to have them stop shifting because of corrosion or a bad shift motor. The tech pages have a thing on cleaning the shift motors and whatnot. IMHO, if you use the electric t-case every so often, it helps keep them working. Both my F-150 and choptop are manual t-case trucks, and every so often in the summer, I'll put them into 4-high going down the road (hubs unlocked) for a mile or two and every so often moving around in a driveway or at a customer's house, I'll yank it into 4-low, just to keep everything moving.

Thank you!
I do understand that. and don't see that as a big problem. I'm not going rock crawling but will use the 4wd a few times a year and I'm only about a 1/2 hr from NJ's pine barrens

I'll stay with the electric. some of these yards have $$$ in their eyes when I contact them LOL

Haha, yea, some of the junkyards around are a bit ridiculous on what they want for things. I've even had some of them argue with me over stupid things... like when I was trying to get a ZF5 transmission for my work truck, I had a couple yards tell me that the transmission they had wouldn't work with my truck because mine has an electronic speedometer instead of a cable driven one because "you won't have anywhere to plug the sensor in". Only one little problem with that argument is the fact that the cable driven ones don't have a hole in them for hooking up a cable anyway. So it's really a non-issue. I ended up getting mad and driving to Erie to get a transmission because I know a yard up there from my college days that still treats me fairly and doesn't question things when I say it'll work.

Well I'm hoping to find out this weekend if the newer transfer case from the 98 will accept the older rear case half, off the one in my truck of if the speedo hole is there for the cable drive.

Trying to split open a case and combine parts isn't the easiest... I'd just put an older T-case with the hole on. Although I thought the newer cases just had a block off plate over the hole, I could be wrong.

We separated the components today! The transfer case that is on the newer trans
Is not going to work ( we knew that!) It had a CV joint and there is no tapping for the speedometer but the casting has a hole where the speedo gear would go.
Learned something today. The transfer case gets a white crust on the aluminum Joint between the cases apparently from salt water or just water I didn't think we'd ever get it apart!

 

[Denisefwd93]

woo.. hard work and this is the "easy" part!

Rusty spline and white aluminum corrosion. It did come apart.. "finally" nothing broke.
