335i Quaife LSD Installation Guide - Who Can Fit?

Hi Folks,

According to the tracking my LSD is now in Cork, I've dug up the installation guide from the email Birds sent me (see below), lots of warnings and cautions so want to make sure the person who fits this 100% knows what they're doing.

Any recommendations for someone that can fit it?

The guide:

Before You Start
Due to the extensive list of different final drives installed in BMW vehicles, particularly across different countries, there may be instances where a the LSD gearset offered differs dimensionally with the gearset installed in the vehicle concerned. It makes good sense, therefore, to check the gearset installed in the car at the earliest possible time. In most cases, it is possible to remove the rear cover of the final drive to check the critical dimensions before committing to the conversion.
The critical dimension is the crownwheel to bearing dimension, marked L4. This can be checked visually by offering the LSD up to the existing open differential. If there is doubt about the configuration, then check the BMW number as below.

BMW Part references, location on differentials

On a BMW "open" differential gearset, the last 7 digits of the part number are located on the rear of the crownwheel flange. (1 216 158) On a BMW LSD, the BMW part number is located on the clutch drum. (1 117 242)

These numbers are the only absolute references that can enable a match to a Quaife ATB LSD. In most cases these numbers can be observed by removal of the rear cover. In some cases, however, it may be necessary to remove the entire final drive.
If in doubt, please contact your supplier with the following information
Differential gearset part number.

Transmission Type
(Manual/Auto/SMG)



Replacing differential in final drive.

Removing and installing final drive- refer to BMW TIS for the vehicle concerned.

Caution! Under no circumstances should you alter the preload of the pinion bearings. In particular, on final drives with a large single nut that connects the cardan shaft to the pinion, you must not use the large castellated nut for bracing whilst disconnecting the cardan shaft.

It is assumed that in all cases, the technician responsible for the installation is competent, and has sufficient skills to work in a clean environment, and can carry out work to a perfect standard.


Drain off fluid.


Remove rear cover, and press off both drive flanges with a tyre iron.

Remove output shaft seals and bearing outer race circlips.

Clean out all oil and use clean working practices.

Caution! do not mix up bearing races and circlips. The preload of the pinion bearings, the backlash and tooth contact pattern will not have to be adjusted again provided the circlips and bearing races are reinstalled in their original positions, and the pinion assembly is not disassembled or altered in any way.


Remove complete differential gear set from casing.

Press off bearing Inner races. Ensure that the bearing inner races are retained with the matching outer races and circlips. If the vehicle has covered more than 50,000 miles, they might require replacement.

Press or tap off crown wheel (cold).



Installation.
Heat the crownwheel to 100 °C. (immerse in boiled water), and place it onto the Quaife LSD, taking care to align the bolt holes. Ensure no water remains in the bolt holes prior to installing the bolts. (risk of hydraulic locking)

Install the original crownwheel bolts using loctite 270.
Torque specification for bolts is 100Nm +10/ -0, then torque angle 30° +4/-0.

Press on bearing inner races to new LSD gear set.

Install LSD gear set into the casing, lubricate bearings with gear oil.

Crownwheel tangential clearance (drive pinion backlash) should be checked with a dial gauge according to BMW procedure. It should not be necessary to adjust with shims. BMW tolerance for a new differential backlash mm 0.06 to 0.14mm. (0.0024 to 0.0055in.). However, it is possible to run a differential with backlash of up to 0.20mm, but this may produce driveline backlash (exactly like the BMW M-Differential, which runs with 0.20mm backlash)


Before installation of the output flange, ensure the round wire snap ring is fully seated in the groove of the shaft so that both ends are fully recessed in the groove. This prevents lateral bending of the ring.


Lubricate the inside diameter with a small amount of anti-seize compound. Lubricate drive flange shaft with gear oil. Push in drive flange by hand and turn slightly until wire snap ring is heard to engage.


Clean the inside parts of the final drive, and the joint faces, then install rear cover using BMW sealant or gasket as appropriate.


Reinstall differential into car and fill with oil. Use BMW recommended or 75w 90 synthetic gear oil, but not LSD oil. Do NOT use additives or any other fluids designed to reduce gear friction. Our recommendation is Titan Sintopoid 75w90.


Test the final drive by running the car gently between full left and right turns to ensure oil is fully circulated. Drive the car normally for 10 miles before any aggressive use. No further running in is necessary.

I'd say your better off looking for a garage with some racing background of some description, there's a Murray Motorsport up in Dublin that do alot of racing, pretty sure they may even sell Quaiff stuff, I'd be confident they would be familair with fitting LSD'Ss but I've never used them for fitting so can't vouch for their work

Deane m,sport in mallow is ur best choice, give Mike a ring 0868794426

Hop on a boat and drive to Birds and let them fit it.

They could fit it in no time.

Would only be a couple of hours drive from fishguard to Birds near Heathrow.

That's a long way to go John :p

I got a quote from a reputable place for 375 euro including the oil. Does that sound about right?

If you can get it done for that money and they will stand over the work go for it.Did you try valdelis.

Valdas would be my preferred option but he's flat out at the moment. I have a few more people to ring tomorrow before I go ahead, but thankfully it looks like I won't be stuck anyway :)

Cheers folks! Any more recommendations meanwhile would be appreciated.

Why not hold out for Valdas, afterall you held out yonks for the new car :wink: I'd much prefer someone known and recommended, especially with an expensive piece of kit where the fit must be absolute.

I know you're only dying to get it fit now :D

Will see how I get on, I will be sure to only let someone who knows what they're doing at it anyway :)

I certainly am itching to get it fitted!

Deane m sport in killavullen is your best bet in cork. I had A fwd gearbox stripped by them before and a new bell housing fitted because I didnt have the gear to do the backlash myself.

You really don't need to travel the country to have work like this done. It's ridiculous to even suggest going to the UK.

That's 3 recommendations for Deane :) will definitely be giving him a call for a chat when I can get out of the office for a bit.

Why would you even want 2 travel 2 Dublin, when you have a person like Mike Deane who is known & highly respected in the rally, & drift scene, for many years in the same county as you.

Here is one going into a C63 in Birds this week.

But Andy, its rediculous to suggest going to the UK.

Like D'uh! :hehe!:

How come a C63 is getting a Quaife? An AMG surely has an LSD from the factory? Did the original diff go bang?

AMG cars generally dont have LSD's.

LSD is only an optional extra on the C63 with the performance pack.

If you read the thread, you'd see that Mike Deane only became apparent later on, and it looks like that's where Peter is heading to!

Didn't know that! 6.2L AMG V8 under the bonnet and no LSD doesn't sound like fun...

Can't really complain the 335i doesn't have a factory one so :D

Pete have you been in touch with xworks?

No doubt they're probably the best, but travelling to the uk to fit it would probably triple the cost between fuel, ferries and exchange rate
