53 dodge truck wipers, overdrive

[jack dalbak]

Been told there's a composite gear that fails in my mechanical, (not vacuum ) wiper motor. Bought a motor on eBay but linkage is different. Is there an aftermarket replacement motor available? Or some way to get wipers working? Also, a guy has a studebaker truck of same vintage and says he may have an overdrive unit laying around. He says the od units are for the most part interchangeable. Anyone know what make od will work? Thanks!

while Mopar did come up with the OD in design they commissioned BW to make the units and part of the deal was allowing BW to market it to other makers....however..this being said, many parts internally are the  same.. but, the input and output shafts, case design and patterns and such are per that of the parent company,,

The 1951-53 truck electric wiper motor and motor arms  should be the same as 1949-52 Dodge DeSoto and Chrysler 2 speed motors. The mount bracket and linkage is truck specific though.

From what I gather the 53' truck could be vaccuum or electric and that they had a different arm so to speak. 53' was that cut off year.

Can you drill holes and make the bracket fit?

I am about to have the same issue when I do mine coming up.

New Port Engineering markets a 12V replacement setup...their website does not specifically have an option for the B-series trucks, but there are other websites who do specify it...or you could fix up what ya got

I installed a passenger car overdrive in my 52 Fargo truck.  A 3/4 inch-thick  adapter  plate machined to take the place of the input bearing retainer can be fastened to the front of the passenger car transmission.  The throw-out bearing collar is then fastened to the adapter. The adapter is bolted to the front of the transmission This plate then bolts to the bell housing.

 

It is necessary to grind the case and re drill one of the mounting holes.    It is challenging but possible to make the column shifter work with a mixture of truck and passenger car pieces.  The parking brake cable must be modified so as to operate the brake.  A small portion of the frame crossmember must be trimmed and the driveshaft shortened seven inches.

 

All in all it might be easier to install a 5 speed from an S 10   but then you need a parking brake which could involve a complete differential swap or relocation of the brake to the pinion shaft of the differential and operate with a longer cable.  Both possible.

 

It is easier to put an overdrive in a US built truck because the transmissions used were more like the passenger car.  It is possible that the R 10 overdrive from a passenger car will fit this transmission.   Only the internal parts from a BW overdrive can be used in the Chrysler .  Main shaft and output shafts as well as the adaptor plate are different.
