A whole lotta parts in a BW overdrive !
 

We rebuild these regularly and, although there are variations in the various models, the general group of parts involved is the same. From everything in the 3 speed side, to the entire group of unique overdrive parts, it really almost triples the total number of pieces we have to keep track of. It also means that these jobs take easily twice the time of a regular (non overdrive) 3 speed transmission. Just imagine if you forgot one little snap ring or oil baffle. The attached photo shows nearly everything except a few odd bolts. I had already installed the ball bearings on their respective shafts for this photo, and the loose needle bearings had already been packed into the cluster gear. Also, I did not include the electric solenoid in the grouping.

Wowza. That's a lot of parts

I bought a basket case BW overdrive for Model A torque tube years ago. The local bearing shops showed no interest in small part orders. Might Mac offer those bearings and seals? Fred A

Those were custom made by a guy in Columbus, Ohio years ago. He’s since passed away. I’m not sure if he used anything special for bearings. The one on the OD output shaft (behind the ring gear) should be a regular 207 bearing. I don’t know what he may have used elsewhere but you can remove them and read the bearing numbers. Chances are that we probably have them. The seals will be another search….probably by size.

Thanks Mac. I set the project aside and bought a Mitchell. I have had BWs and only got caught with the reverse issue once. The Laycock in my pickup may be the best yet. Fred A

Here is my experience with bearings. I've repaired a few machines over the past year that needed bearings. I just measured up what I needed and google usually got me a number. Depending on what you are working on you may need metric measurements. A cheap set of dial calipers that you can hit a button too switch units works nicely when you see a size that does not coincide with any fraction you're aware of just hit the switch and see a whole number.
