I was in a bone yard and saw a Timken 2-speed axle which is very little larger than the small Timken used in the 3/4t and 1t trucks. Anyone ever seen one? Any idea as to what gear ratios it might have had?
For '48-52 F-5 and F-6 had them as an option, I think they might have come standard on F-6. One of the guys with the big trucks should pipe in and confirm this.

Jack - Ford's two speed ratios on both F-5 and F-6 (1952 reference) were either 5.83/8.11 or 6.33/8.81. I believe earlier and later year Timkens would have been the the same but will see what the others can add on the subject. I'll be interested in watching your post over on STT to see if Studebaker ratios were different. Stu
The experts over on STT don't find it as a listed option on Stude 1t, but that's where I saw it. Knowing Ford used many of the same Timken axles, thought I'd ask a wider circle of experts for info.
BTW, I'd love to see a photo of the F-5/6 axle referenced. Those 5.83/8.11 or 6.33/8.81 ratios would be much lower than a 1t E15 V8 Stude would need, so the F-5/6 might be the much larger axle than the one I saw. Again, the one I found was the same size as the small vertically-split Timken.
Yep, Eatons were the 2 speeds used in lower series Fords. Model 1350 on the F5 and F6 as an option, 17500-1 on the F8 from 48-52. A Timken 2 spd was available as an option starting in '58 on the F,C 1100. For 51-52 the Eaton model 16600 was added to the F7 as an option. Hmmmm, misfiled my pics, I'll snap a couple of a 1350 under my 48 F6 and post shortly.
Pics of an Eaton 2 speed under a 48 F6. This one has the 5.83 / 8.11 gear set of the 2 ratio sets Stu identified. And looking through the data I have the 2 speed was optional on both the F5 and F6 (conventional and COE) as BobJ stated above. The 1350 was used on the F5 and F6 through '56 (500/600). And through '57 on the F,B,P, 500 and C550. This one is shifted with vacuum vs electric, Big Jobs were electric. Not sure when change to electric was made on the F500/600's '53?
And here's a pic of a Timken 2 speed that was holding the back end up on a '47 Dodge WJA59 3 Ton. Only other one of these I've seen is at the Golden Age of Trucking Museum in CT. Not a Ford, but a good looking truck for '47. They had a more promounced square front end unique to other models. I had the problem Havi has with his F8 tho', no way to get it home But then I wouldn't be here with this great group...
Looking for information on a vertically split with 2 speeds? Or just info on a vertically split Timken? If a 2 speed on a vertical split, it wasn't an add on unit or like the old Halibrands that a friend had in a '42 Ford coupe. Otherwise I'm guessing you're getting into the 30's era trucks?
Jack - I looked through my old 1953 copy of the Motors repair manual a while ago and found only the style Timken that Bob has pictured. Nothing split like our Timken 51524s, and having a two speed feature. So I'm at a loss. Stu
Hey Stu / Jack~
I saw in a post yesterday by Penn Dick a reference he made to a winter quick change rear end from 1 ton Ford and Stude's. I PM'd him the link to this thread and asked if he would share his wisdom....
We're ready for any help from anywhere. I'm familiar with the early QC racing rears which used the single-speed Timken gears, short side housing and axles. However, AFAIK, they didn't use anything from the two-speed. That's because in fifty years of working with trucks and race cars, I've seen hundreds of the single speed Timkens in Studes, Fords, Jeeps, fork lifts, loaders and other machinery and dozens of the QC rears but this is the first small Timken two-speed I've ever seen under anything. If Timken single speed parts are getting scarce, imagine looking for two-speed parts!
I am in the process of building a 1952 F5 COE and have a 2 speed rear axle that I don't need. I am not allowed post to classifieds yet but thought I would revive this thread and see if there is any interest in one of these. I don't really know what condition the axle is in and wouldn't be looking for much more than the scrap value. Basically it's in my way in the shop and I don't need it. However I would hate to scrap it if someone else needs it for their project. Same thing goes for the front as well.
