If anyone has ordered a quaife rear end, can you let me know what came with it? I appears in all the web pictures that there is no ring gear. I can't imagine it running without one. Did the pinion gear come with it? What else did you have to purchase to installit? I would imagine that a professional installation would be preferable. I would appreciate any answers any one may have.

Thanks,
Bob Joseph

Thanks, Baz ...

That would be appreciated. Also, confirm with Quaife what modifications/adjustments are needed to use the LSD with a non-specified differential -- for example, if Quaife says its LSD is for the 3.44, what would it take to make it fit with the 3.67 and vice versa?

hi talked to mark (sales) and he says they are making 25 diffs (some are on back order )and they are to replace the orig fitment so if you are going to use a crown wheel that was not 3.44 then i think you will need to talk to rally bob about a spacer

Makes the one that I sold for $625, seem like a bargain. Bill H., you got a deal! What's new in Wisconsin?

Later....

It was a bargain all right. I foresee a new thread in the near future about installing a Quaife LSD...

If 3.18/3.44 Quaife, then 4mm spacer!

Install?? I thought it would be a simple plug n' play, right? LOL

I'll probably get a Quaife LSD. I have discussed the installation with three local sources -- Crew Chief/mechanic (SCCA Mustang, Ford Focus rally car), a Drive Shaft/Differential shop, and an engine builder/restorer (probably the best, but his fee-structure resembles that of an attorney's -- he bills when he has dreams about working on your engine/car -- I've been there). Although I'll have someone else do all the skilled/tech stuff, I'm sure I'll have lots of questions for you folks.

A question for Otto, Bob, and others -- Is the 4mm spacer available or will that have to be fabricated? Also, I assume that I will need the OGTS shim kit, axle seals, gaskets, and possibly bearings (axle and carrier). Anything else?

Baz, thanks again for checking with Quaife.

The 4 mm spacer will have to be custom. Years ago Mantapart produced them, and I used to have my own made locally and used to sell them through C & R as well. I don't have any left however...
If you want to have one made locally I can mail you a blueprint of the spacer however.

Bearings are gonna be a big expense, the hard-to-find suckers are the pinion bearings. Axle bearings aren't too bad, and the differential side bearings are reasonable too. But the pinion bearings are Opel-specific. Alternatively, I';ve used the Isuzu impulse pinion and differential bearings, and they worked just fine, plus they're 1/4 the price. You need an Opel crush sleeve and pinion lock nut though, the Isuzu one doesn't fit an Opel ring and pinion. HTH.

Sounds like a real good reason to use the complete Isuzu gear set - nut, crush sleeve and all. Though I have usually replaced the crush sleeve, in other diffs, with a presisely made solid spacer so that the crush sleeve's perchant for colapsing further in severe use can be avoided.

BTW: "bearingsuk" on eBay, UK can supply complete Manta A & B diff bearing sets

Agreed Jim, the Isuzu stuff is generally a lot more available and certainly cheaper. I did find that the Opel pinion nut is a better fit even on the Isuzu pinion gear however, the OD of the Isuzu nut is larger and I had to grind a socket to fit within the housing.

Thanks for the link BTW! A lot of guys in Europe and the UK have been saying it's getting harder to find those bearings....these cars ain't gettin' any younger!

4mm Spacer

I'm also goin to order the LSD unit, and I guess I will need the 4mm spacer also. I would gladly split the tooling cost, If you get me one too.

Sounds good. The blueprint arrived a day or so ago while I was away. Thanks, Bob. I will take it to a local machine shop Monday for his perusal. I'll keep you posted.

4mm spacer

Let me know what it costs or if you can get a group price, I may be interested in getting one.

Thanks,

Sorry that I couldn't get back to you sooner. I was hospitalized with pneumonia (I thought it was just the flu) Sunday morning and was released only this afternoon (Wednesday). {Hey, Vickie/Allen, aren't you guys glad I canceled out on Saturday's "Opel gathering."}

I will try to get some costs for making the 4mm spacer in the next day or so. Dave, I paid $1,350 (listed at $1,495 by Quaife NA) which includes shipping/handling. As far as a quaife "group buy" (three or more) ... Bildon Motorsports ([email protected]) will knock off only $20-30. Maybe you can cut a better deal. I ordered mine last week and it's due in a couple weeks ....

Got word back from Quaife. We're expecting your diff to arrive in about 2 weeks.

I already got my eyes pooked

at Quaife NA, mine should also be getting in soon. I'm in no hurry for the spacer as I don't plan to put it in for a month or so. but let me know how it goes..

Quaife Installed

Finally installed the Quaife. I checked through four rear ends in my parts stash and the last one was a 3.67. Took the Manta to the track the next day for T&T and took off over 3 seconds on my previous best time

. However, some of the better time came from advancing the timing from 30deg to 36deg. But I could definitely notice the "pull" out of the turns. BTW ... you don't need the 4mm spacer when the Quaife is installed with the 3.67. The 3.67 ring gear is a bit thicker (4mm to be exact) than the 3.44 ring gear. All that was needed was a small shim between the carrier bearing and the housing. Also, you don't have to count the teeth on the ring gear to determine if it's a 3.67 -- if the ring gear is thicker than your 3.44, then it's probably a 3.67 or > ... another way, if you can find it, is the gear ring is stamped with the number of teeth (I found that after I had the gear out and cleaned). The pinon gear in both the 3.44 and 3.67 have 9 teeth.

Next race is this weekend ... the real test.

Thanks to Baz, RallyBob, Otto and others who provide advice and info.

Almost 11 months later but LSD is in...

It took awile but the LSD Unit was finnaly installed... Car is still not running, but in a couple of months we will test the results.

Lessons Lerned:
1. The Quaife carrier will only accept the 3.67 gears(No Spacer), the 3.44 gears are too Fat and do not fit. I had the spacer on hand, but could not be used. If I was mounting 3.67 gears onto a 3.44 carrier then yes I would have needed it.

2. Finding 3.67 gears was hard, but this forum put me in touch with the right people, (Thanks Dave M.)

3. Once you have all the parts everything seems easy.

4. Four Months between Dissasembly and Reassembly, made it hard to remember were, and how parts whent together. (Thank God for FSM Sacans)

5. Hiring an experenced Mechanic with proper credentials, is a plus. Or in my case a necessity.
