looks to have a two-speed rear axle, which is a good feature. if it does, it isn't an F rated truck; dodge dropped the FA version in '51. so this is either an HA or GA truck, and probably has the mid-frame brake booster. i have a '48 FA, with the 2-speed and the brake booster. both features are highly desirable and make these medium trucks useful on modern roads (not interstates). as bob pointed out, when the brakes are adjusted correctly on these trucks with the midland booster, they brake very well, even fully loaded. as a guess, i'd say you have a B-3-HA-152. could have a synchro 4-speed, and probably has the 25" 237 motor. the 2-speed rear should be an eaton 1350 (vacuum shift). truck has nice add-on front turn signals and mirrors.

big red looks great, bob! it is my favorite B-series truck, so many options and in such marvelous condition. i would not drive that in our new england winters, but i drive mine all year because it isn't so nice.

had a great time running a half-day with the pic-nic crew a couple of years ago in NH. one of these things is not like the others.... if there are any locals in the oneonta/cooperstown area that aren't doing the whole thing, i highly recommend at least dropping in for part of a day with the group. a lot of fun, and great to meet some forum members in person. i hope to do it again when it's in new england again.

i can't help with identifying your transmission, but new process transmissions were in dodge trucks in the 40s. the oem 4-speed in my '48 1.5-ton is an NP non-synchro.

if you are addressing the OP/thread starter, realize the thread is 7 years old, and the last activity, until yesterday, was 7 years ago.

had to slap on the chains to collect the last of the sap last weekend.. season is done... time for clean-up.

same.

good for the truck, and good for me, too. i always enjoy driving it, especially when hauling something.

maple season is a bit early for me this year, but that's our new weather. collected sap yesterday, and began boiling. should be drawing off syrup today. quick video of sap flow from one of the short lines, and pumping to the truck... sap flow & pumping

also, the canadian blocks were 25", not 23". so the length isn't going to be of much use in identifying the size.

it's all good! glad you got them done.

i thought you were asking about the inner fender, not the fender itself.

from what i recall, i installed mine from inside the hood, not from the wheel side. are you trying to install it from the wheel side?

when i first rebuilt the 237, circa 2009, i didn't touch the original oil pump. prior to the rebuild, running pressure was around 40 psi, and idle was around 15 psi. i was fine with those numbers. when the 237 threw a rod circa 2017, i pulled the pump and installed it on the "new" 251, although i did clean it and run oil through it prior to installing. pressure on the 251 is about 42 psi running, and 20 psi at idle. the original pumps are pretty solid, and work well enough. seems like a big risk to run a new pump if the original pump (or whatever pump came with a given engine) still works. in neither case did i submerge the pump in oil prior to installing, and it worked just fine (and pressure was indicated immediately during starting, prior to running).
