A555 transmission bearing number list

[black86glhs]

It is the same bearing, just doesn't have the rubber side pieces. You can transfer those from the old bearing if they aren't beat up.

Well crap! I wish I'd known that before I spent the money on another bearing. Oh well, I guess I'll have a spare if I need it.

Thats the problem with aftermarket parts. You never know what you are getting. The one in my trans had timken and 207 stamped right on it. Yet the last timken bearing I bought ( intermediate shaft case ) was a torrington.

That's the 5707 right? The one I got was a Torrington as well. I always thought Timken manufactured their own bearings. I guess I was wrong. Or at least not all of them.

[Tony Hanna]

Something else I'm kind of curious about. I had forgotten that the sealed bearing has a groove around the outer race for a snap ring. The 207 I got doesn't and according to the picture, neither does the 207s. I'll know for sure once the one I ordered gets here. I wonder how important that snap ring is? If I can do without it, then the 207s should be fine. If not, I may still end up having to order one from the dealer.

I am not sure about the grove, from what I can remember, the bearings looked the same except for the "sealed cover" factory was black, timken was blue. When I get home later I will take a look. I have 2 555 gear sets in the garage. One with a stock bearing and one with a timken 207. I will let you know later. I know this timken was used in the trans I am rebuilding and the trans was in a 12 second charger and had a bunch of 1/4 runs on it with no failures even without a chromo bearing plate.

I looked at both gear sets. Both bearings have the groove. The question now is did timken change their bearings? or does the S also have the groove??

[fleckster]

I'm trying to summarize all of this info and to make it a sticky or add it to the Knowledge Center:

For the five speed manual transaxles:

Differential:
Bearings (2) - Timken Set #11
Seals (2) - Timken #3459S

Input Shaft:
Bearing (Front) - Timken Set #4
Bearing (Rear) - Timken Set #5
Seal - Timken #3732S

Intermediate Shaft:

A-525/A-520/A-555
Bearing (Front) - RNU070618-6 (Mopar Part #4377723) ; Timken #5707
Bearing (Rear) - Timken #207S

A-523/A-543/A-568
Bearing (Front) - 07NU0720/23B (Mopar Parts #4641225 (was #4531531) - Bearing; #4531529 - Inner Race; #4531528 - Oil Feeder)
Bearing (Rear) Timken #207S



Please check this over and let me know if this is correct or if there is anything that needs to be added. Once the info is judged to be accurate, I'll make it a sticky and/or have it added to the Knowledge Center.

Thanks for everyone's help!

207S is not the correct intermediate bearing. It is very close but will not work. This still appears to be delear only. All of the other numbers look good.

[fleckster]

I am working to get both the A-568 and A-555 Intermediate Shaft Bearings in my hands and see if I can use my Maintenance contacts at work to see if they can come up with an alternative bearing that might be available from other sources and hopefully cheaper. I'll keep everyone posted as to what, if anything, we can come up with. I figure if they can patch up our broken bearings in our Fuji Lathes and other major equipment with alternative and cross-reference bearings, they might be able to help us and the Maintenance Manager I work with is more than willing to assist me. What do we have to loose?

Thanks for the double check/confirmation, Justin!!! We need to have Barry check and see if he has the Mopar Part # for it so I can include it and even order one with my discount so we have a new one to get measurements from.

What's different about the current 207s?

[Tony Hanna]

What's different about the current 207s?

It's missing the groove for the snap ring that the original bearing has.

[black86glhs]

It's missing the groove for the snap ring that the original bearing has.

You mean you can't just glue it in the side plate???? Damn.













Just kidding. I'll talk to this guy I met at school and see if he has any ideas for what to do. He runs mills and cnc machines. He might have an easy way to cut the grooves in them and I have a spare snap ring he can measure with. Just in case John can't get anything going with his maintenance guys.

[Tony Hanna]

I (very) briefly entertained the idea of 3 or 4 small tack welds around the outer race. No need for drastic measures like that as long as the correct bearing remains available from the dealer though.

[fleckster]

Okay, so does anyone have the part number for this Intermediate Shaft rear bearing? I'll pick on up and see if anything can be matched to it.

Then I'll just have to figure out what to do with my damaged Turbo III A-568 case...

John,

You're talking about the sealed bearing right?
If so, I've got the one out of a 555 sitting right here. It's a Koyo bearing and has 83A5958 on the seal and 6207n on the outer race.

HTH,
Tony

EDIT: If somebody can try to get their hands on a Timken 207LO. This may be it. I don't have the extra money to order yet another bearing I might not be able to use or I'd order one to check it out. Unfortunately I can't find a picture of one anywhere but I did run across a thread on the other board that mentions the 207LO as a replacement for the Koyo 6207N.

[Tony Hanna]

Well crap!
As far as I can tell, the only difference between the 207LO and the 207L is that the 207L includes a snap ring and the LO doesn't (but has the groove). Unfortunately, neither of the two are sealed.

Here's a pic of the 207L. I still can't find one of the LO.


I wonder how critical it is that a sealed bearing be used?

[black86glhs]

I just did a cross reference. The 6207N crosses to a 207LO(obvious I know), which is also used in a few Ford 3 and 4 speed transmissions. I have yet to find a pic either. If I find one, I'll post it.

I'm guessing that the seals are not crucial.

The 555 rebuild bearing kits I got from Transtar included outer mainshaft bearings that look very close to the 207L you just posted with no seals. The main difference is that they have 8 balls vs 7 in the pic you posted. They are marked "MRC 306SG5 USA" on the outer surface

I found a list of Timken bearing suffixes, and "L"="Snap ring grooved outer, snap ring supplied", and "LO"="Snap ring on standard side. Snap ring not supplied".

I'm guessing that the 207L is the one we want unless we can find a number for a sealed version with the snap ring.

The Timken suffix listing shows a "FFLB" suffix for "Special Bearing with two single lip snap-in seals and snap ring". When I searched for 207FFLB, I found nothing, but "207FFL" found a couple of obscure hits. I also searched for "207SL" and "207SSL" and got hits at Rockauto. But the pics for these all look the same as the one you posted above.

Sorry this is such a long post, but check what I found on Amazon.com:



http://www.amazon.com/SKF-2RSNRJEM-S...048893&sr=1-11

Of course its currently unavailable, but at least we have a pic of what we're looking for.

I hope this helps the search.

Here I go again, I found the non-sealed version of the bearing at Advance Auto Parts:

When I put in my zip code, it shows low stock (call first) at all the stores listed, but I'm guessing they can get it quickly if needed.
