I need some help with bearing identification. the Bearing Cross Reference Charts sticky says that the 1508 needle bearings (2) are a B-1012. My problem is that the manual says this is a 3/4 I.D. bearing. The sticky calls it a 0.3730 which is what Applied Industrial Technoligies says the B-1012 is. My question is what is the proper replacement for the 1508 bearings? This is a 5053 transmission by the way.

Thanks Mike. I don't suppose you have a Torrington cross reference number for the new 252-6 Toro number?

I don't know if this is correct or if it will help but I have the #1508 bearing crossing to a B1212.

That's what I was hoping for. Unfortunately the cross reference chart lists the 1508 as a 5/8 ID. I ordered the B1212 hoping they will be the right ones. Thanks for your help. I'll post my findings when I install the bearings which won't be for about two weeks.

Thanks Martin. I'll check your numbers against what I ordered.

Other than the different axle size both our numbers match up. Thanks again, Martin.

My bearings arrived today. :woohoo:

I'm leaving on vacation and won't be able to install them until the 17th. :no:

Looks like they 're going to fit.

The b-107 is the correct bearing for in 3/4 inch input on the 1 1/8 inch axle trans. Just had to order one from napa.

for a 3/4 input i would be using the b-1212.

are you sure that napa gave you the right number? from experience i know the b-1212 is right for the 3/4 input shaft trans with 1 1/8 axles.

The number on the old bearing pulled out of my trans is a b-107.

Napa could not find a b-1212

I've got my trans cleaned up and ready to install my bearings and seals this weekend. I'll let everyone know what I find out with regards to the correct numbers for the B-1212 from Torrington.

just went out and checked the numbers on the removed bearings from my 5058 trans rebuild. my memory is fairly good for stuff like this, but just to be sure i checked.....

the input shaft on this trans is 3/4", brake shaft is 1" and it has 1 1/8" axles.......

the open bearing on the input has torrington b-1212 on it.

like i said earlier the b-107 is for a 5/8 shaft. the later transmissions used a 5/8 shaft but the wh 1508 bearing for that shaft crosses to a b-1012 which is......

same in id od but the width is narrower on a b-107....

if you have a 5/8 shaft i would still choose the b-1012 over the b-107 as its considerably wider. i dont think napa really looked at the dimensions real close as the width is a important consideration. i ended up putting two open bearings on my input as there was room for them, and theres more support for that end of the shaft.

theres no way that i would be happy putting a bearing in there with 1/4" less width than even the factory installed.......

My housing is only 1/2 inch thick for the input bearing and seal. I just got the bearing 1212 and it is too wide. No room for a seal and it hits my high low gear assembly. The number I took out of my 6 speed said b-107 stamped on it. Are we talking about different transmissions? I have a 71 raider 14

yes we are....

not sure when they changed from 3/4 to the 5/8 input, but if i had to guess the old 3 speed(without the high/low) had the 3/4 and the trans with the high low has a 5/8 input. hence the 5/8 bearing that you pulled. the b1212 is for a 3/4 shaft. easiest way is to measure your input shaft.......

The b-107 is the correct bearing for in 3/4 inch input on the 1 1/8 inch axle trans. Just had to order one from napa.

nope..... this is for a 5/8 shaft. so you must have a 5/8 input trans........

as far as the bearing width, i havent done a 5/8 shaft trans, so cant comment on your clearance problem. are you saying that you got a totally different bearing? it was packaged wrong?

i assume that since it hasnt been mentioned before by any of the trans guys on here, that the 5/8 input bearing (open end) would be the b-1012 with a 3/4" width.

these things can be frustrating at times, im sure you will get it worked out though....... :thumbs:

Sorry about being confusing but I have never rebuilt a small trans like this. I'm used to rebuilding baton fuller transmissions in like a Internationals and other trucks. It is nice to be able to pick up a trans and not need a forklift. I think the hole trans is about the same weight as a single gear. Lol

Well Murphy's Law has struck the Funengineers shop. I layed out all my bearings before pressing them into place and found I was short one. I checked, double checked and finally triple checked. Yep, I ordered the exact number of each bearing the owners manual said was required.

Here-in lies the problem. The owners manual is wrong. The wh pn 1529 (Torrington M-12121) lists only one bearing. There are actually two. So... I finally got the second bearing and will be able to finish this thing next weekend. At least I'm able to paint parts while I wait.
