A525 bearing kit, does it work with A555?

[tryingbe]

Would an A525 bearing kit work with a 87-88 A555?

bk138 overhaul kit shows up for both the 525 and the 555, so pretty sure yes.

It should work just fine for ya. I personally would look for a better sealed ball bearing on the 5th end of the intermediate shaft though. I bought one of those kits for a 523 and it came with the same cheezy non sealed ball bearing and it was only 7 or 8 ball bearings vs the oem 9, does make a difference on the turning smoothness.

Also, the intermediate shaft bearing towards the bellhousing side will not be as wide, and will not have the same amount of rollers as a 555. They do work, but if you are going to do massive beating on it and racing, I'd try to find the 555 style bearing.

If you find it, let me know :thumb:

I didnt mention that part since the proper bearing is not available and probably never will be. The 5707 is cheap enough and very easy to come by that you could probably change it once a year or say every 12k and not worry about it blowing up.

This was do to the 5707 bearing. But, it had a TON of passes on it......

I remember that thread very well.
Do you have the specs on an original 555 bearing ? ID-OD, height and # of rollers.

[Reeves]

These dimensions were taken by me on a brand new Koyo bearing:

Koyo RNU070618-6
Solid Steel Housing
12 Rollers
2.253" O.D.
1.401" I.D.
0.782" Width

For comparison, I measured a Torrington bearing from a A-525:
Torrington DB-43932
Stamped Steel Housing
13 Rollers
2.254" O.D.
Couldn't measure I.D. due to being an odd set of rollers.
0.700" Width

Also for comparison, I measured a 5707 bearing brand new from a parts store:
INA 67147 5707
13 Rollers
2.254" O.D.
Couldn't measure I.D. due to being an odd set of rollers.
0.700" Width

I also measured (2) intermediate shafts to find the O.D. of the shaft and what the I.D. of the bearing should be.

Shaft 1
Very low mile A-525 = 1.400"
High mile A-465 = 1.400"

We really need the trans knowledge center back.. :mecry:

That's some great info Reeves. Thanks for posting it up.

[Reaper1]

Thanks for the info!

Hey Reeves...what's your opinion on the 5707 in an application where launching hard will be a rarity, but 400whp will be a reality along with prolonged high speed?

I would at least check it once a year or so. I don't think it's the bearings fault, as much as it is the hard launches on the narrow rollers and stamped steel outer case.

[Reaper1]

Hmm...is there room for a wider bearing in the case? Or how about using a bearing that has a smaller ID (larger rollers) and modifying the shaft? We already kind of do that when we have to repair the shaft, so it kind of makes sense. Also the surface speed of the shaft and the rollers will be lower.
