main difference between 1350 & 1354

[88 Red Ranger]

1) What is the main difference between the two t-cases? 2) I see the 1354 might have a front drive flang but will the 1350 EVER have a front flang? I registered a few weeks ago and have been doing ALOT of reading. I have also been searchng many different things. 3) Will the Electric 1354 front output shaft fit into the manual 1350 case? Thanks for having such a great site with all the information. It has helped already and thanks in advance for answers to these questions.

The 1354 does have a fixed front output yoke, yes.

Most but not all 1350s have a slip-yoke front output.

A select few mid-late '80s STX trucks with the Highrider option had a 1350 with a fixed yoke, though it is not the same case as the 1354 that was to come later.

Welcome to the site

Thank you 4x4junkie. I have been looking at that tech page and noticed the 1350 as a slip yoke. What I did not find was if I slit and E1354 and a M1350, will the E1354 front output shaft go right into the M1350 with not modifications? What make the 1354 a better tcase? Or is it just because it has a fixed yoke?

Does anyne make a larger yoke or flat flange for the front or rear of the tcase? Are the ujoints a 1310 size or smaller?

 

[4x4junkie]

The 1354 has a 1310 front yoke, rear is a 2.5" pattern flange ('90-'97). '01up trucks have a 3" pattern rear flange, which can be swapped onto the earlier case if desired.

The STX Highrider unit I mentioned above has a 1210 front yoke (tiny!).

The fixed yoke is the 1354's primary advantage, though '93 & later units also have a slightly more robust planetary gear and shift collar setup (the earlier design which is also the same in the 1350 isn't known to fail often however).

No you cannot swap the front case or shaft unfortunately.

 

[88 Red Ranger]

So I can not pull the E1354 front output shaft from the tcase and put it into the M1350 tcase? Or does it take ALOT of work? Or are they two totally different cases and share nothing the same?

the main difference between the 1350 and the 1354 is that the planetary gear set on the 1350 is a 4 pinion set,on the 1354 it's a 6 pinion set.


everything else is just window dressing.

No it goes much deeper than that...

The front output shaft is contained within the front housing on a 1350 (which also contains an internal u-joint). That same housing ALSO contains the manual shifter components. You cannot switch the output shaft setup separate from the case, therefore the manual shifter too (I have read reports the rear case halves can be swapped between them, but that doesn't accomplish anything if you were attempting to create a manual 1354 out of a 1350).

Believe me, if what you want to do was possible, everyone else would be doing it too.

Not all 13-54s are 6 gear. The early ones were 4 gear.

You can swap rear case halfs with no mods.

On a side note. You can make a 13-54e into a 13-54m using 13-50 internals. I've done it, I've even talked about it on here or explorerforum (I dont remember which one). The biggest thing is drilling and reaming the case in the correct location. ( it must be reamed if you want the shaft to seal, drilling doesnt give a smooth enough finish.)

Edit: found the link.

That's good to know. The bulge in the 1354 housing for the e-shift rotating assembly didn't interfere with installing the shifter shaft from the 1350?

The only problem is that the 13-54 case is thicker where the shift shaft goes through.

this is what i was referring to as 'window dressing'

my apologies,i think i was in a bit of a mood last night.i must say,though-i was not aware that the 54 ever used a four pinion gearset.i guess i never got into one of the earlier ones.

Will the 1356m from a full size F-series bolt in or are adaptor plates and parts needed?

different bolt pattern,index diameter,and spline size on the input shaft.

so you're pretty much screwwed on that one....plus the fact it won't fit between the ranger's frame rails.too bad,though...it's not a bad case.
