Dan , It looks like your new/used parts are set up for 6 lug wheels . Are your wheels 5 lug ?

Your truck is a 1947 , you mention a race for a B-1 . B-1 is a 1948 - 1949 truck .

Tennessee Clutch and Brake , as mentioned earlier . Lots of the members are happy with their work .

Lots of good ideas posted . Some members have said that a coil often gets hot when it fails . So touch it .

There is no oil up that way . Could it be anti-freeze ?

The bulb is probably stuck to the gland nut and that could twist the tube and break it . .

Farmer Jon posted a link to one of the hubs on ebay , and with that listing part number , I was able to read other descriptions on other listings for more information . So I bought a new hub . Thanks guys .

The Speedi-Sleeve is shown in the photos , it is a very thin steel band that is pressed over the sealing area . You would use it with the standard seal . If I can find the part name and part number for the hub , i would price a new one . If obtainable .

I had my engine rebuilt 11 years ago . It has had a leaking front main seal that has recently gotten worse . The engine is from a 1939 Dodge car . When I pulled off the timing chain cover , the speedy sleeve came off too . The speedi-sleeve has cracks . I have ordered a new front main seal and when the new seal gets here I will test fit it on the flange/hub that fits on the crankshaft and into the timing cover . To my untrained eye the flange/hub has a slight groove worn into it from the seal but I will see how well the new seal fits . I can't find the proper name and part number for this flange/hub it anyone has this information .

I see part number 696383 for WHM 45 , 47 , 48

lostviking , There was a thread on the car side of the forum ( not recent ) where a member put a more modern mopar overdrive trans in his car . It might have been the A833 . If you can find that thread , you might be able to glean some tidbits of information there .

For those who don't know ; The 3 speed trans have a different bolt pattern than the 4 speed trans , 1939 - 1947 .

The bearing retainer is centered side to side . Top to bottom ? , I don't know . That is a dimension that I didn't note .

Here are diagrams that I made several years ago when I was looking for an overdrive . These diagrams are for a three speed that would fit the 1939 - 1947 trucks .

4 speed = no synchros

General , If you have a 1940 Plymouth truck , it isn't a V series . It is a model PT 105 . And my parts list for PT105 doesn't show synchro parts for that tranny 3 speed in 1940 . My 1941 plymouth PT125 3 speed has synchros in 2nd & 3 rd .

My Pin Point Parts Specifier shows VC (1/2 ton Dodge ) with a synchronizer plate and spring package for the 3 speed . Also in my parts book for 1941 - 1945 WC WD158 WD20 WD21 3 speed shows synchro parts .

Another inexpensive alternative . A used travel clock from ebay . i threw away the lid and made a home-made sheet metal mounting bracket . it takes a button battery that lasts a long time . Easy to read .

1/8 inch is a VERY thin disk . Something is wrong here . Perhaps 1/8 inch of material on each side of the disk .

So you are about to get the problem with the inner seal sorted out and get the bearing greased . You might be wondering if every time that you want to grease the bearing , do I have to pull the axle shaft out ? No . There is a plug in the housing next to the bearing that you can remove and dab in a little grease . That plug has the same thread size as the wide base grease fittings on your truck . So why didn't Miss Mopar and Mister Dodge just put a grease fitting in there instead of a plug ? Because the bearing is protected by seals , one on each side of the bearing . You don't want to pressurize that area and blow out the seals . Dab in a little grease , turn the wheel to spin the bearing , and dab in a little more . Your shop manual will mention some of this .

That part # 20 should be part # 26 .

My parts book shows Two seals . Part # 17 is the inside seal . mopar 651678 . Part #20 is the outside seal . mopar 891437 .

Is the vent plugged on top of the differential ? And as you probably know , the bearings are lubed with grease and not with the differential oil . Is the axle shaft worn where the seal rubs ?

There are two seals , one between the glass and the windshield frame , the other seal goes between the windshield frame and the body . I think that the original just kind of folded in place around the glass but I think that you would get the best seal by more or less glueing the glass in place with a thick liquid sealer .

Usually you have to get very aggressive to prepare the frame for new glass . Break the old glass with a hammer , use a propane torch to remove the old seal . . The four little machine screws that hold the two sides of the frame together can get very stuck too . They thread into a small bar . If I remember correctly the thread size is 10-32 .
