Does anyone have the modern bearing and race numbers for the 35-36rearend and the 42-47 1/2 ton pickup pinion shaft. I am using the 42-47 pickup center section and 35-36 axle housings along with the 37-41 axles to make a slightly narrower open drive shaft rearend and want to look through the 200+ new bearings and races I have to see if I have the ones I need. Thanks Rod

JSeery · 03-25-2015, 04:38 PM

As far as I know they are the same as they have always been. When I took my numbers for a 38 rear axle I was converting to a quick change they had the bearing numbers in their books.

Some time back I posted the Ford to Timken interchange numbers on this forum. try a search. If you can't find it PM me.

The carrier bearings are different pre 37 to the 37-48. Why is this? Looks like it could trip a chap, not using the correct carrier bearings.
What are the carrier bearings tied to?
Ie, if you use a pre 37 diff carrier in a pair of 37-48 axle casings, do you use the pre 37 diff bearings? Or 37-48?
Do the carrier bearings have to match the banjo or the carrier or the axle casings?
Just clarifying the swapabilty of the center banjo, and trying to prevent mix up of wrong parts.

Mart, I think it's the axle casings that dictate the bearings. things were generally beefed up in 1937. Bigger axle tubes, and bigger bearings. Diff carriers are the same. Pilot, I guess stayed with the lighter 35/36 setup.

Thanks for reposting. I found the old thread last night. Looking at the bearings I have , I will have to purchase and trade for them. Seem to have quite afew NOS 49-54 Fords, 57 and later and 38-47 trucks. May post a trade thread in the swapmeet for those that might be willing to trade NOS for NOS. Thanks Rod

I think I know what your getting at.
All taper bearings have the same numbers from all suppliers? As in there standardized numbers, this of course excluded Ford which had their own number system.

Guess that was a little confusing (and maybe not that helpful!). I was referring to the numbers on the bearings themselves, Ford (for the most part) used standard bearing but also assigned their own part numbers.

Rowdy · 03-26-2015, 10:47 AM

Seems helpful and very understandable to me. Most of the NOS mentioned above have the standard Timken Bower numbers on them. Been double checking those numbers this morning as the old drunk who I bought them and many other parts from seems to have mixed some of them up. Frustrating having to double check the parts in every box to make sure it is what it is marked. Rod

Don't know if this is a common thing on your side of the pond, but on this side I've pulled many an early Ford part to bits, be it axles and rear ends or front hubs/brakes. Most often the bearings in them have a Ford part # say I tug a four cylinder differential, the bearing will have Ford (sometimes timkin) then B4221 on it, not a timkin or other manufacturing number. Later V8 ones would have 18-4221 or 69-4221. These numbers I believe were only used by Ford.

Rowdy · 03-26-2015, 02:40 PM

That is common pre 1940. During or slightly proir to WWII some standardization was put in place from the bearing manufacturers and most bearings and races in Ford boxes after that will have the standardized numbers on them. Rod

johnh7 · 03-26-2015, 03:56 PM

Be careful when you buy the bearings as I just read that some Timken bearings are made in China. https://www.fordbarn.com/forum/showthread.php?t=164677

Rowdy · 03-26-2015, 10:17 PM

Finished going through the NOS Ford bearings. I have 4 boxes that the numbers have faded away. The standard part number is 25577. Doing some research I think the Ford part number is supposed to be 8M-4221(49-51 Mercury). Can anyone confirm if this is correct? Thanks Rod

deuce_roadster · 03-26-2015, 10:49 PM

Another bit of info, those B- rear end bearings are for the 4 cyl carrier that has the 3 axle spider shaft with its own spiders. The races with B- numbers for the axle housings are also different then the 18- ones. The 18-bearings are for the V8 carrier that has the 4 axle spiders and of course they are different then the 3 axle spiders.
