R151F question
« on: Oct 15, 2019, 08:32:01 AM »
Hello guys
Iíve been trying to locate the answer to this question for the past few days. The R151F judging by the pictures of it, (please see image area circled in red) Iím assuming it has a T-Case already attached at the tail housing, if this is trueÖ is it a gear driven T-Case thatís attached? And then for dual cases you only need one extra case to have a dual case setup?
Im asking because I want to purchase an R151F and install it into my 82 but If the above is not true I might go a different route. Iím trying to keep my T Case shifter(s) in the original location. I ran across a picture of an R151F with dual cases and the area circled in red had a block off plate with 2 additional T-cases behind it.



Thanks

You can run a turbo(forward shift case) or a top shift case behind the trans.  It clearly does not come with case attached as shown.
You will require a 23 spline case or replacement input shaft in order to run behind an R151.

The r151f does have the exact same shifter locations for the Trans shifter and front case if you utilize the forward shift set up for the front case.   This is the exact set up I have in my 1983.  r151f, Duals with MC08 and total spline 4.7's in the rear,  all 23 spline.  I like being able to use the original boot if desired for the front case.  You obviously still have to cut your hole in the floor for the rear case.

As Gnob mentioned, the transfercase is not attached to the transmission in the pic you posted.  The area you circled is where the transfercase lever is located with the stock forward shift t-case.

This is what the picture you posted is missing,


This is what a topshift transfercase looks like, and should be similar to what you have now in your '82,


This is what you would need to buy to run dual cases w/the r151, it goes between the transmission and a 23 splined transfercase.


This is what the R151 typically looks like with dual transfer cases


Running dual cases and keeping the transfer case shifters near the stock locations, will require running something like this from RADesigns

Do you happen to have a picture of your setup ?

The rad designs is nice but they do not make it for the forward shift.  If you run it like you have pictured above there will be a big new hole in the sheet metal and not in the stock location for the front tcase.  It is a clean set up though over all but I have seen guys actually having to cut large sections of their sheet metal to accommodate the rods.  So for the OP this may not be what he is looking for.   I also preferred the one smaller hole of just the rear shift over the RAD or daves offroad.

I can take one later.  Mine I don't have all finished up with boots and all though.  But again I like having the forward shifter in the stock location and the r151f allows this for the front case.  I considered the rad stuff like posted above but it would have had me cutting a big section of floor out to make it all work being that my transmission and tcases are rather close to the floor.

So if you go with two top shift cases (block off the forward shift plate) does anyone know what the offset is from the R151 transmission shifter  to the 1st ttransfer case shifter center? I  was planing to run the RAD design triple shifter (already have it)

ALSO
I was wanting to go with the R151 just to keep my options open for a future engine swap (22re 3rz or 5Vz not decided). Problem is I donít want to loose my center console and the 23 spline upgrade is $$$$. My plan is to run dual cases with a triple stick setup regardless if I go with the R1515 or W56.
So if I could run the R151 + 1 forward shift T Case +1 top Shift T case + triple stick shifter (Rad Designs of course) that would be great, but Iím not sure the triple stick will work on the forward shift. 

Also I was wanting to go with the 23-21 spline adaptor instead of upgrading the t cases to 23 spline. Save on Parts and labor, ease of installation

Thats what i was afraid of, the non compatibility with the forward shift.

But I could block the forward shift location and just run dual offset like the G or W series right (with Tripple sticks)?

Their kit does not work with a forward shift set up.

the pic above shows a blocked off forward shift with duals.  Yes you can do it.  And again if you run the triple shifter you can expect to have to cut large portions of your floor but you will have all three shifters in one location.  I think all the answers you are asking are above now in this thread,  Aside from the actual measurement from forward shift hole to top shift if blocking off original location.  You can estimate that rather easy from his picture.

Here is what my shifter set-up looks like, note it uses the stock boot because the t-case shifter has an offset!!  https://imgur.com/vY4NPOz  https://imgur.com/dx6IyF0

Thanks OOPS thatís actually a pretty clean setup. On the twin stick portion is that mounted on the 1st or 2nd t-case? Iím assuming itís on the 2nd one correct?

Thanks man! They were the only black and red wheels I could find in town here to match the truck, seems Powell and Spitfire are the only game for wheels now, its been years sense I last looked so I was little shocked.



I would have liked to find a set of ricta slime balls but the shape is all wrong in the hand.

 & custom 3" S.S. dump pipe, R-151f transmission, marlin dual ultimate transfer cases w/ triple shifter, SAS, 35's https://board.marlincrawler.com/index.php?topic=98969.0

WOW

Thanks so much for sharing that!!! This is what i was thinking about doing, I already own the RAD tripple stick setup and I wanted to modify it like this.
