tranny question

[Todd B]

would a tranny out of a 1950 F model be syncronized?? How do you tell when it is sitting on a shelf?

Thanks, Todd B

Hello There,

The 4 speed type spur gear (crashbox) trans. has the power take off cover located in a forward position of the trans. case and the drain plug going in a 30 degree angle to bottom of case.

The 4 speed helical gear synchromesh trans. has the power take off located in rear postion of trans. case and drain plug going parallel to bottom of case.

Hope this helps you out.

bob (dodgeb4ya) will correct me if i'm wrong, but i believe the F models (nominal 1.5-ton) all had non-synchro 4 speeds. if you know for sure that the transmission came from an F, it won't be synchro'd.

Dozerman51's info is correct-watch the drain plug angle. A syncro trans was available as an option for the 1950 and up F series trucks. The input shaft is a large 10 spline-I think 1-1/4". Not 1" X 10 spline as on the 1/2 through 1 ton truck 4 speeds.

according to bunn's B-series book, the F-size trucks were only available with the 4-speed non-synchro transmission. doesn't mean they weren't, just that his research didn't reveal a 4-speed synchro available as an option. he also indicates that the F was discontinued as a model after 1951.

as you point out, the way to id the transmission is via the drain plug angle and the location of the pto cover.

The info I mentioned is out of the factory service bulletins and factory Data books produced by the Dodge truck division. I personally have never seen a syncro 4 speed in a F series 1-1/2 ton truck. But the literature and parts books list it as an option. The F models continued all the way through 1953 as shown in the data book. I'm not sure about the C-1 series 1954 models though.

it appears mr. bunn could have used some of the literature that you've obtained.

i appreciate that you provide a wealth of information about the 48-53s.

i went and re-read some of the truck information in bunn's b-series book. i misremembered about the F series. it was the FA that was no longer offered after 1951, the F was offered throughout the run. however, he does specifically say that the Fs were only available with the non-synchro 4-speed.

The F series trucks were the cheaper entry level 1-1/2 ton trucks. I guess they couldn't offer much as for equipment to keep a economical price.

yup.

makes the earlier ones, like my '48, interesting. it has the 2-speed, deluxe cab, passenger visor, triple bumper overriders/guards, fresh air/heater assembly.
