Well, over the past 2 months my car started feeling weird. It gave a nice clunk when you would disengage the clutch, and would clunk real hard on heavy shifts. I figured the differential was going out, and I was right. But I didn't expect it to go out like this, especially this early

*Story*
I was leaving school, I hopped in and fired my car up. As I put it into reverse and let the clutch out I got the usual hard clunk, no big deal. I put it into first gear and started to take off, the parking lot was completely snowpacked, so I just went straight into second. As soon as I let out the clutch, the car caught traction, jerked a little, and then wouldn't move. That is when I got out and gears and metal pieces on the ground.

Pictures-

I couldn't believe it blew off the whole part where the linkages bolt up


All the parts that I found, the sun gears and most of the case was on the ground, but the pin and a large section of the case was lodged into the differential area


The pin, I am assuming this caused it


And one of the sun gears, alot of wear on the inner part from what it looks like


Basically I am screwed. This was a mint S1 tranny on my b16 setup. I think what caused this was from 7 Grand launches on 10 inch wide slicks with a 50 shot of nitrous. I hadn't known about the technique of preloading the tranny, so alot of stress probably took place on the launches.

I want to see If i can just replace the diff side of the case with a new one with a good diff already in it, does anyone know how hard this would be?

!!!!Damn!!!!
you did all that on a mint tranny, that is rediculous....WOW holy poop on a stick dude.... that right there is wack

 

Not exactly mint if the transmission was bad/was going bad.

Or did you mean to say that it was mint before your dragstrip launches?

Confused here

 

omg that might have done it rofl

 

ouch . . ???

 

another mint b16 cable tranny down the drain, no wonder theyre getting so hard to find

Mint as in it used to be perfect, and even after the diff started going bad all the gears were perfect. Absolutely no grinds.

 

my ls tranny did the same thing

 

slammin' gears.

 

As if....Thats just wrong.

But it obviously wasn't mint if it then exploded on you?

No, I mean the gears and syncros were mint, as in they didn't grind any gears like 90% of the cable trannies out there. Kind of like having a mint condition s2000 straight off of the lot. Then you go drive it at 140 and jump it off a cliff into a tree. The car was mint.

 

You win.

 

That failure comes from doing one wheel wonders all the time.

You think so? In the burnout box the car always smoked both tires. I just think it was the extreme stress being placed on the differential by not preloading the clutch.

Yes, yes I did

 

"I hadn't known about the technique of preloading the tranny"

Can you please explain this preloading technique?

 

I've been told this and it happened to me so I tried to pass on the same information but most people still pay no mind to it.

Pre 92 cable B-series tranmission (S1, J1, Y1) have a weak link in the non-lsd equipped tranny's. It's the differential pin, 92+ rectified this problem by using a hardened pin. I've serached this before couple of years ago on Honda-Tech, I forgot who the name was, but they had enough insight about this problem.

I serached after my J1 exploded while doing 80 on the freeway in Cali leaving us stranded about 100 miles away from home in 03. Never raced the CRX at the tracks, we just did typical driving since the motor was installed back in 99. The diff pin went and sent the spider gears shooting out the casing. Just like your pic.

I should have read the warning people were giving. Change you're diff, put in an LSD, etc.........I learned the hardway, but I ended up buying a JDM YS1.

 

^^^ Yup ! Pulled my s1 tranny after the first funny clunk and the diff pin was broken. Wow glad i got it in time. Sorry for you loss.

 

damn thats a big hole

Sure, when dragracing and you are at a complete stop ready to launch, you hold the button down on your ebrake and pull it up so your car cannot move. You then rev your car up with the clutch in to your desired RPM. You then let the clutch out just enough so that the car does not move, but load is being placed on your tranny and axles, then when you want to take off, let off of the clutch and the e-brake at the same time.

****, the donor tranny I am getting my diff is another open diff s1. Is it possible to put in the hardened pin from the newer trannies to get rid of this problem, I don't have enough cash to get a LSD.

Being that I'm in Hawaii I have the stock YS1. But these clowns here don't want to listen to me.

 

i did the exact same **** trying to go up a steep hill from a stop

its normal

That failure does look to be burnout related. Destruction from shock usually results in stripping the teeth from the pinion gears or the FD ring and pinion.

 

That exact same thing happened to me last week except mine only put a hole in my tranny case about the size of a dime and i could still drive it. There was wear on the pin in mine too, but not nearly as much as yours. I wonder if it's a honda-wide problem, because my tranny is d-series (zc/si hybrid).

I took the tranny apart and looked at all the gears and made sure that no teeth were nicked or missing. I had other trannies so I put made a new final drive by putting the pin and sun gears from a dohc zc tranny into a usdm si differential (the si tranny was showing wear on the pin and sun gears, but the dohc zc looked good yet). I then got new differential bearings and one other bearing that didn't look too good got replaced while it was apart. And logically I put everything in a different tranny housing. When all was said and done, it could've sucked worse because I only paid $80-$90 for the bearings and I did all the work myself.

Good luck fixing yours.
