These are the only people I found that dealt with Cusco LSD's. These guys are very knowledgeable and customer service is excellent. They were very accomodating when it came to getting the rebuild kit as fast as possible. I reccomend these guys to anyone that needs something from Cusco!!

I hope I'm not violating any rules here by giving them some praise.

So last night my friend and I tackled taking the trans out of the car, cracking open the trans and disassembling the differential. We've done trans' before but this was the first diff. All in all it went quite well, the diff was alot easier to take apart then I thought it would be.

I spoke with Cusco this morning they said the rebuild kit is about 220 bucks it will take 60-90 days to get here from Japan or I can spend another 100 bucks and get it shipped within 8-10 business days which is what I'll end up doing.

After inspection of the synchros and bearings, they all seemed in good shape I think I might get by only replacing the clutch discs.

Now for the pics.

The trans and working station












The Diff




Diff Internals






The Problem










Good Times!!


Old Faithful!! Electric Impact


Dirty spoom "breaks"


The Bat Cave


Good Info:


So thats it, in about 8-10 business days I will have an update and the complete rebuild and driving impression. I love this diff!! I would like a ride in someone with and ATS in the future, I've heard there is nothing to complain about with them!

Thanks for looking, let the questions and comments roll!!

I think you guys need a new beer choice. Bud flavored water sucks...

 

BL is the beer of choice. My friend doesnt drink or eat anything else

 

You need some real beer to work on cars...
All that stuff will do is interupt and make you have to ****....

How did you end up determining it was a cusco LSD? I know you questioned it for a while.

 

Dude....I cant even drink beer and work on my **** at all
Props... looks like fun G/L with the rebuild

 

so i take it you werent at the pre hin meet last saturday

 

i dont understand differentials. where do those clutch disk things go and what do they do/how do they work? what made you decide to rebuild it? what were the symptoms that told you it needed to be rebuilt?

I second this. Budwieser doesn't have a single product I can drink :barf:

Nice work though. Looks like fun.

Searching the interweb, I finally found pics that looked exactly like this.

I was there for a little while but left to go to the Osbourne Park autocross.

8 of the discs slide into the diff casing then you put that spaceship looking thing in there and then 8 more discs. Only one set of the discs seemed to be damaged decently.

Those discs allow the diff to give when cornering. Its like a welded diff but no binding in the corners. With both wheels off the ground, if you spin one the other will go the same way. If you and I push opposite ways we will only fight ourselves.

 

Subscribing!

I'll rebuild my ATS LSD before next season hopefully.....!

(Although the the tranny is out of the car right now, I'm not going to spend the $...)

I was really suprised how easy it was. I spoke with ATS, his are only 250 bucks and it only takes about 5 business days.

 

just read this for clarification. it has pretty pictures too.

lol, I made my friend read that yesterday!!

 

Where do you buy your new disk or rebuild kit ? i need to make the same for my EF9 cusco LSD ...

 

1-888-591-6277 is the number to an IL place that can get them.

 

Good stuff, definitely looking forward to your post-rebuild impressions.

Lol, there's 2 of them in that garage. One is an 88 and the other is somewhat stock. Also two 4-wheelers, both 400, one with a 440 kit.

 

Does anyone have dealing with cusco? I spoke with NAPSUSA, they have to send out pics to Japan and see if they have the rebuild parts. Apparently next week is a holiday in Japan. I'd like to get them ordered and shipped before that holiday!!!

 

have you thought about upgrading to the sealed diff bearing instead of reusing the tapered ones?

No, Info???

Just buy the sealed bearings instead of the tapered, the shims are the same - you will probably have to re-clearance the diff but its much easier. Just tap the outer races out of the case, and install with the sealed bearings.

 

Whats the difference, other that ones sealed and ones not. Where do I get sealed bearings? Will honda have them?

 

All LS transmissions, and GSR/ITR after 2000 got sealed bearings.

The difference is they're a lot easier to set the clearance on, and IMO a more durable design.
