Thanks for the archive data. I'll add it to my log. Good to know these were built in South Africa.

The below picture shows the shift pattern with Hi range being forward on the long lever, and Lo range back toward the seat. The short lever that sits between the driver's legs is the engaging lever to move from 4x2 to 4x4. Stu

Edit - It occurred to me that you might have the older style brass plate (and transfer case) that says "Positive" and "Compensating". The below old thread contains an explanation of that function provided by Chuck Mantiglia of Chuck's Trucks in CT. Stu

hmmmm... i dont have 4x4/2x4 lever anywhere. does that mean i have permanent 4x4? will i save fuel if i disconnect front prop shaft , as im mainly driving on tarmac?

 

Thats really nice i am in the Uk to

 

Hmmm. Now I'm stumped. I'd suggest emailing Chuck, unless he stops by here to comment. Full time 4x4 is a possibility I'd guess. Stu

 

Hi just got one F3 M/H 1951 Ambulance that needs a little love i hope that it;s ok to contact you, right now i just want to say hallo from Denmark, mine are similar to the one from the civil defense 6cyl with 4 gear, see you Hans J Grundtvig

 

Welcome Hans. Glad to have you. Would this below linked for sale ad be your truck? Stu

I will also add my welcome to the new members across the pond! Lets go back to the first truck, front diff on the left side as you look at the truck? That would make it a single speed transfer case truck correct Stu? How many levers should it have? Just the one between the drivers legs for in/out I would think. We need a picture of the floor of the truck. Maybe its just missing a lever.

 

Differential on the left side, Mark, should mean it has a two speed transfer case. Wonder how many of these have survived, and wonder whether some pictured are actually the same truck. Hope Hans can tell us more about his truck. Stu

 

Says drive shaft goes to front axle on left side as you look at the truck. Would that not make it a single speed? As I read it I assume he is standing in front of the truck, left side makes it the passenger side.

 

Yup, that's what he said. You can read better than me. Stu

 

So do R3-4s, the single speed transfer case trucks, have only the lever in between the drivers legs? Thats probably a bad question as maybe some of those trucks had the cross shaft to move the lever to the pass side.

R3-4 single speed t case............1 lever, passenger side front diff

R32-4 two speed t-case.............2 levers, drivers side front diff

Is that correct?

 

The R3-4 has one lever to the right of gear shift. The R32-4 and bigger models having two speed case have the lever between driver's knees. That's the in/out lever. The first I have record of use of the cross shaft for the two speed was the '53 F-250/M254. Stu

 

It makes sense now that I think about it. The single lever would be to the right of the trans shifter. With the front output of the single speed t case on the pass side everything would be from center to right on the case. Clear as the new wind driven snow!

 

Got a lot of that here lately! Stu

 

hallo Stu.Youre right it is my truck now, in a fine condition, i feel so lucky, Hans
