This is to serve as reference.

Type-R's come with either Tapered Roller bearings or Ball bearings on the diff carrier.

Whatever type your gearbox came with, that's the type you stay with.

Do not switch bearing types. Do not use tapered bearings in a casing that originally came with *****, and do not use ***** in a casing that originally came with tapered. The casings have differences in some of the machining dimensions.

There are reportedly many people who've made such a switch successfully. Under race conditions such switched gearboxes can destroy themselves. There is no good reason to invite such a disaster, and no advantage to be had in making a switch. Either type will do the job acceptably well.

It sounds like Scott almost had a gearbox go BOOM on him...I'm glad that you had knowledgable support people that kept that from happening, thanks for keeping us updated.

How's that new gearset?? Tried it out yet?

I think alot of us would like to know this too....

 

Uhm, no.

I may not have a running car till Thursday night or Friday morning, my first chance to "try it out" will be qualifying Saturday afternoon.

Scott, who's prefers the Joneses to the Murphys....

hahaha, the lesser of the two "evils"

 

I disagree to an extent. The Tapered roller bearings are a pain in the ***.... and frankly, if i had to replace a set of tapered bearings.... i'd make the switch to the newer style.

Matt,

I agree that given a choice the Ball bearings are preferable for the reason you stated, but you don't have that choice according to my sources - who have nothing to gain one way or the other.

Scott, who can imagine worse pain in the ***...but I have a hell of an imagination....

 

I don't know if I can believe that unless I see proof.

If you measure correctly and get the proper shim I don't see why it would matter....

Well when two people who really know what their talking about tell you otherwise, taht would be all the proof that i need. Its not like scott is propogating an Internet rumour.

I didn't hint towards anyone starting a rumor.

Unless there is some documentation or proof of the difference between the tranny cases.. it just doesn't make sense to me.

Experiences to me mean nothing unless it's obvious what the problem was. Maybe if there was more information I might agree somewhere.. but all I'm gathering is "don't do this because it'll be a disaster."

My question is.. what dimensions cause this?

Honda to my knowledge doesnt even sell tapered bearings anymore.
They tell you to convert. All the part #s i look up are the same between the years.
Tapered bearings were used up until 1997 and in 98 they switched(integra vtec anyway)
and the part numbers for the 2 remain the same. Visually they are the same as well(to my estimation).
If you have more specific facts about this i'd like to hear it. Otherwise I dont see a problem here
other than the fact that tapered roller bearings are the cause of 90% of our
transmission failures, which btw the ball bearing types eliminate completely.

I just bought a set thru my dealer this week.

Scott, who won't have detailed specifics anytime soon...I'm moving on for now, and just wanted to share serious warnings I was given...

I agree with steve on this, I've done hundreds of trannies switching and checking clearances ... if there were breakage it was neve due to carrier bearing failure due to difference in machining, the parts used to convert one to the other are very much interchangeable and work fine if done correctly.

ditto, we always convert from tapered to ball bearing and havent had any problems. its just simplifies things and makes check clearances easier.

 

I tried ordering the tapered one's through http://www.acuraautomotiveparts.org and I got the sealed ball bearings. In either case, I prefer the sealed over the tapered due to the fact that you don't have to set the preload. And plus it's a pain to take the races out of the the tranny housing.

 

Ive been using the sealed BBs in a tranny that had tapered roller bearings originally for 2 years now, with over 50k street miles, 15 or so HPDEs, and shitloads of auto-x and drag strip action, with no problems whatsoever. Please elaborate on the problem and under what conditions etc, as you give zero support to your statement.

Actually, find that to be quite easy. Maybe its just me. either way, tapered bearings suck

 

can someone tell me the part number for the tapered bearings that i'll need.
my thread is located here:

thank you very very much.

 

part numbers can be found here:
http://www.acuraparts247.com

This info is very suprising since I see many people switch over to the new bearing type and have not heard of any problems with the switch.
