Overdrive in a B3B truck

Recommended Posts

I could well see some changes made through the year and noted in a tech bulletin due to things like parts deliverly not on time and production runs still going strong so a few cars 111 cars get built with 118.5 axles and the like...the oil issue in transmissions were still a problem all the way through in 1993 that I am aware of as Mopar says on the dipstick you can use x oil but the tech bulletin say you cannot..Mopar was directly responsible for the failures of trannies based solely on these misprinted dipsticks...

"There are differences between the truck and the car bellhousing to wit:
1. the car bell housing and tranny rest upon a cross member white the truck bellhousing rests on mounts attached to the frame rails.
2. the car brake and clutch pedals are mounted to the frame while the truck pedals are mounted to the clutch housing.
3. The front mounts are so similar so that that is not a concern, attach that mount then work in the back.
4. Fuel pedal linkages may work. . ."

 

That's a bunch of work....

The '35 Dodge truck above has a nice setup that the B3B can't readily take advantage of due to the frame cross-member on the later trucks.

 

I've been looking into GearVendors overdrive (Laycock) units for 1947 and earlier pickups. It's an excellent unit in all regards and well supported.

 

The things you may have to do to install the GV (or equivalent) OD unit (Gear Vendors offers a lot of options, so this is just one way to do it):

 

1. You'll want to maintain the hand brake setup, so fabricate an extended linkage for this.

2. Modify the frame cross-member just behind the transmission to allow the installation of the OD and re-located brake.

3. Re-locate the gas tank to just forward of the rear frame cross member (where the WD-1 and Power Wagons have them).

 

The most difficult part of all this is the modification to the cross member to accommodate the extra 16 inches or so of OD unit.
