    512 cid C series on Dakota chassis- build thread

    Couldn’t you just cut the necessary taper into the inner edge of the outer boards so that their inner edges are parallel? Then the inner 3 boards would all set in straight with straight shovel strips.

    LEAking rear end near u joint

    I’ve pulled many a seal with sheet metal screws through the metal flange area. Some with a slide hammer tool, and some by gripping the screw with Vice Grips and prying against the pliers. Or tapping on the plier with a hammer.

    LEAking rear end near u joint

    Likely need to replace the pinion seal. May also need a Speedi-Sleeve on the pinion flange. I would also suggest to clean/inspect the axle breather. If it’s plugged up there will be a pressure buildup inside the axle housing that exaggerates a seal leak.

    How to determine if I have "Fluid Drive"?

    3 speed transmissions in Dodge trucks have synchros since at least the 40's, and with the introduction of the column shift 3 speed in 1950 they certainly would be synchronized. (at least in 2nd and 3rd) It was the 4 speed trans that remained a spur gear type up through '50-'51. The B3 trucks were the first to get a synchro 4 speed.

    Rear Axle Identification on B-1-F

    Yes, these trucks weren't built for high speed. But also keep in mind that your tire diameter plays a factor in overall RPM vs. Speed. Your "F" trucks have taller tires than our light duty trucks, so higher numerical gear ratio is used to adjust for that. Although something in the high 4's or low 5's would probably offer you better cruising speed, if that's what you are after.

    How to determine if I have "Fluid Drive"?

    The trucks used Fluid Drive with the column shift 3 speed and the floor shift 4 speed from ‘50-‘53. Also in ‘53 the FD was offered with the semi-auto trans, but then it would have a Truck-O-Matic badge on the hood. Tim and Don offered quick tests to know if you have FD without crawling under the truck. However, either way you should not need to double clutch your column shift 3 speed. If you do, then the synchronizers in your trans are bad.

    Need clutch and brake pedals stop pic.

    There’s no need for a pedal stop like that. The pedal should rest against the floor. If your wish to lessen the noise, a thinner piece of rubber against the bottom of the floor could be used. Also, the hole in your floor has been cut open quite a lot. It should be just slightly wider than your pedal arm.
  8. No part numbers Rob? Although they probably wouldn’t do anyone any good these days. Also, the B1 wouldn’t use a cable, but I know that you know that too. 😉 Too bad they didn’t list the length on the other 4 cables...

    Water Distribution Tube Installation

    How clean is the block? Could there be some rust scale in the tube opening? I believe I had to tap lightly on mine to get it into place. It just had to reshape itself a bit to fit into the block.

    December 7th, 1941

    College students that don't know the significance of 9/11? 😲 Just goes to show the state our education system... The Pearl Harbor attack happened 26 years before I was born, but I'm still very aware of the significance of Dec 7th, 1941, thanks to the education that I received.

    Split Ring Tire Question

    Max PSI is for Max load. Unless you are using your truck as it was used "back in the day" you could run with a lower pressure and improve the ride quality. Bring the pressure down until you see the tire start to squat a bit, then add 5 lbs.

    headlight switch bezel thread size?

    I have to wonder what the acid did to the contacts inside the switch, and inside the circuit breaker.

    1956 Plymouth Suburban 230 fuel pump

    Contact the folks at Then and Now Automotive, (a.k.a. Antique Auto Parts Cellar) and get a fuel pump rebuild kit. Their kits are inexpensive, fairly easy to install, made for modern fuels, and their tech support is top notch. http://www.then-now-auto.com/antique-auto-parts/

    clutch pedal bushing

    It's sort of complicated... The clutch and brake pedals are listed with bushing, and the bushing isn't listed separately, unless it's a Fluid Drive truck, Truck-O-Matic, or larger truck. Those have a different clutch pedal and linkage system and list the bushing separately, for some reason. And there are several different part numbers depending on model year and size class. Does DCM reference an OEM P/N? The first column designates series number (1-4), or a - indicates all series. The next columns are size class, B, C, D, etc.

    Removing heat control tap on head

    You could possibly try putting a little heat into the head around the base of the valve, but either way it’ll probably take a fair amount of torque to break it loose. Have you drained the coolant form the block and removed that hose first?

    Electronic ignition again

    Interesting observation. I noticed this summer that my Westach is no longer accurate and I wondered if it was due to the different signal from the Pertronix. I contacted Westach about it and they stated that several of their customers run their tach’s with Pertronix. I was going to drop my points distributor back in and test it again for verification but I hadn’t got around to it yet.

    Similarity between ‘52 Concord and ‘53 Cranbrook?

    Interesting... A ‘49 truck 4 speed would likely be the spur gear type without any synchros. It must have taken a lot of effort to shoehorn that into a car chassis, for what you’d get out of it. Especially since the car bell housing would likely have to have been modified to allow it to bolt up.

    Similarity between ‘52 Concord and ‘53 Cranbrook?

    That looks like a truck transmission. I’d suspect that you’ll need to do some fabrication, even if you could find a replacement tunnel hump.

    Serial Number Question

    Well, the light duty trucks have the chassis serial number stamped into the frame, on the left front side, between the front spring mount and the shock mount. I found mine where the red arrow is pointing. Note the shinier spot on the frame... Maybe the medium duty trucks have the stamping in a different spot???
  21. Merle Coggins

    Serial Number Question

    There should be more to that number on the frame. Try sanding lightly before and after those 4 digits and see if there is more. The chassis serial number should be there, and that is what is needed for identification.

    Brake pedal oscillating when pressed.

    A pulse in the brake pedal, when brakes are applied, is usually due to a warped brake disc or drum. If the drum is out of round the shoe will follow the concentric circle causing the pulse/oscillation feel.

    Clarktor - Flathead 6 with fluid coupling.

    I don’t know what type of bell housing they used in that tug, but in the cars and trucks, with FD, you need to remove the trans from the bell housing first. Then you can remove the clutch from the FD, then the FD form the crank. There will be 8 nuts to remove on the block side of the crank flange. It’s probably best to pull the engine with the bell housing attached, then swap things over to the replacement engine before installation. If you are unable to turn the crankshaft then you won’t be able to get the FD unit off the crank without removal of the bell housing. And if this is the case you will probably need to drive the 2 locating dowel pins back into the bell housing, and out of the engine block. They are located just above the lower bell housing bolts at the back of the block. With the pins pushed back, and the engine out of the vehicle, you can lift the bell housing up and over the top of the flywheel/Fluid Drive unit. This would then provide some access to the upper nuts on the crank flange.

    yet another glass question

    Yes, the divider is attached to the glass and is the moving type, as mentioned above.
