Got the tranny on the ground finally (yes D, I'm slowtarded) and got to the part where you remove the cap to get to the ring...



Hrm, that metal looks a bit more powdery than I recall. Let's look down in there, shall we?



Okay, there's a little loose component in that hole, let's get some pliars and pull it out.




Call D back: "Hey D, I'm holding a metal fragment that says NTN on it."
D: "That's part of a bearing."
Me: "Do I need that ring to come off completely or will it just snap to the loose position?"
D: "Use two screwdrivers, get the ring to snap open and pry the casing apart. Don't forget to take out all the bolts."
Me: "Thanx dood."



That's a trippy photo of the inside of the tranny housing. Do those cracks mean anything?




Well, at least it won't be hard to figure out what the problem is....





Hrm, that's a fuzzy looking magnet...



The moral to our story is if you start having weird tranny behavior, it's probably best to stop driving and pull it apart. Obviously I've gone one well and truly fuxored bearing, but at a glance everything else seems OK. D tells me that I'm gonna have to take everything apart and clean it piece by piece, but if it saves me the money of a new tranny then I'm not gonna bitch too hard.

Still, bleah. 60k miles. Probably should do the timing belt while I've got everything apart....

 

That can't be normal to wear that quickly can it?

 

can't say i've seen one like that yet.

check your mainshaft bearing whilst in there (in clutch housing).

They are not cracks.

 

yikes, I've also never seen that one before either. Maybe something else is broken/loose in there causing the bearing to explode.

I'd go with D's advice and clean it completely out and make sure everything is ok.

 

what bearing is that usually called?

I've never met a DC2 tranny that didn't have some kind of weird behavior at some point in its life. I'm thinking it's time to add a better FD to mine

 

I'm a complete newb on rebuilding a tranny, but I am wondering is it possible to clean that magnet without pulling the tranny apart ?

 

looks like some hard technical stuff, good luck

unfortunately, no.

 

Yuck..... man i just cant pass this up..

Well Scott if you kept the car on the track and not in the dirt "like you drove mine" then things like this would not happen ...

I have been waiting for two years to get that shot in..
For every one else who was not there i will explain:
Scott test drove my CRX at the GRM event in 03 right off the track then back on apologizing all the way to the in car camera..
Hhhhmmmm now where did i put that video..

Damn, i think you have see it.. " when the dust clears and Rambo jumps back on track all you here is @!$#$@!#$#$#@@# sorry guys over and over...
Its hard to be mad when your laughing so hard..

 

To this day that's the only press/customer/event car I've gone wheels off in while working at GRM. I'm starting to think it was probably the build quality

It is a pretty strange failure, especially after 60k miles, if it had been a flaw in the bearing you'd think it would have manifested itself sooner. D, you didn't leave your shirt in there when you did the ATS FD, did ya?

Now I'm torn between the manly route of cleaning each part myself and doing the reassembly that way and taking it to the local race shop and using up my tax refund.

Not that I know jack about tearing down a transmission, but maybe something in the innards would give you a clue about the cause of the failure? I doubt the race shop would have/take the time to examine all the little goodies.

 

, So I'm not the only one that breaks something in a way that no one has ever seen!!! When I break it, I break it good!

Clean it out yourself, not that hard.

You could get a magnetic drain bolt, then you can clean it everytime you change the fluid

 

Is that hole to the right normal?? I've never noticed that before. It looks to me as if the casing has a big ****** hole in it.

 

I noticed that to =/

 

First, The hole is normal .... That is how you get the pain in the butt spring clip in and out...

Second, Man, did Scott change the subject and now its all my fault???? Hhhmmmm i see a guy with a busted trans and i put the car back together wrong, that video will be very short in coming..

Third..... Hey Scott i have seen one of these fail like this before it was the result of a heavy hand when the trans was reassembled. the bearing's outer race gets cracked and what you have there is a result of it not being caught upon assembly. " done it my self so i am not throwing any stones here, so don't send me any hate mail "

 

See the long crack there on the out side of the bearing case? side loading the bearing did not seat all the way, hence the long crack through the case...
Like i said i have done this twice before i still have both bearings to prove it.....
Be sure to pull the lsd apart and get all of the hard metal out of it or it will lock up and you will be off track again " this time your own fault "
If you need help drop me a line.....

"Cracks" are normal on any casting, they are called flashing. They should be positive (higher than the base level) not negative (below the base line of the metal). Negative would be a result of the metal braking apart but positive is actually called flashing and is a result of cracks in the original mold that filled up with molten metal. You can take a drummel to them if you want but those are so small they aren't hurting anything.
If you have OCD or are a weight **** you can take a drummel to the outside of your trans and nock off all the flashing...

 

oh ****, i was looking for this thread the other day..... !

but I was looking for any user named "scott" or "scott @ grm" etc...

 

Thread from the dead.

It's been a sweet while, but the race shop I took the tranny to is in the peak of their season, so it was a backburner project for them for quite a while. That's what I get for not doing it myself, right D? Although they did do a chemical micropolishing of the gears (google Isotropic Superfinish) so we'll call that some value added. Since the whole shebang was apart anyway, the guy doing the rebuild suggested replacing a bunch of the springs and synchros and stuff to give it that like-new feeling; thanks again to Len at Baranco Acura for the parts hookup on that one, saved me much $ and had everything in stock.

The tranny is back together and sittign on the floor of my garage, hopefully I'll have it all back together by this weekend. Toda flywheel and ACT clutch are installed. I miss driving my R.
Pics and such on the GRM project car page HERE

 

Yeah it was good 'n broke, but the newly polished gears look pretty bling.
