Re manufactured BMW M135I & M140I Rear Differential with Wavetrac LSD (2.81) Auto Gearbox
DESCRIPTION:
We provide the highest quality Re-Manufactured Genuine BMW differentials.
The differentials are built with genuine OE components, bearings are a modified item to resolve the fault in design, fully stripped down, cleaned using our in house ultrasonic cleaner, tolerances, preload spec and contact mesh checked along with all new seals, and non consumables replaced.
Units are checked fully and tested before dispatch.
PROCESS:
Most BMW axles from 07 onwards were manufactured with a friction welded ring gear and open differential. This can cause some headaches for installation concerning vehicle downtime while the factory differential/ring gear is separated by precisely machining the parts away.
The Crown wheel and pinion get a full overall, all preload shims custom ground in house to a 1 micron tolerance, along with perfect backlash to accommodate the new differential housing. This differential is now ready as pictured for immediate dispatch.
Complete ready built Wavetrac Differential just add oil
Wavetrac ATB LSD
ARP Ring Gear Bolts
New, Genuine BMW Axle Seals
Backlash Setup to OE Tolerances
Precisely Machined Ring Gear
You will need to spec oil, for this application we advise for Motul Competiton 75w140.
The Differential has been completely reworked from top to bottom, new pinion bearings these will not be replaced from other dealers! seals and non consumables, spool and planetary gears replaced. Retrim of the gearing to correct tolerances, reassemble gear kit with correct backlash, pinion depth and gear contact mesh to GearLab spec. New hardware and fully ultrasonic pumpkin and rear case along with pinion flange cut and ground.
Each Differential is individually setup correctly to Gearlab specification and tolerance’s.
WORKMANSHIP:
The workmanship and attention to detail that goes into one of our Differential builds is bar non you will not find any corners cut here. We pride our selves on our gearbox builds not only internally but externally and guarantee our boxes for 12 months on fitted units.
All Differentials are built by hand in house, every part is scrutinized and inspected and nothing is left to chance. My Differentials are fully Re-Manufactured units which means all serviceable parts are replaced.
I find my self more and more repairing Differentials that have apparently been reconditioned months prior to find out that all that may have been changed is the absolute minimum or nothing at all.
All preload and pinion shims custom ground in house to a 1 micron tolerance.
A properly rebuilt automotive part.
Rebuild includes full strip and cleaning of internal oiling system, with modifications to increase oil flow if required.
The item has been completely disassembled, cleaned and examined for wear and breakage. Worn out, missing or non-functioning components have been replaced with new or rebuilt components. It is the functional equivalent of a new part and is virtually indistinguishable from a new part.
WARRANTY:
We’ll also guarantee our work for 1 years, or 12,000 miles (whichever comes first) on fitted Differentials, 6 months / 6,000 miles on ‘take-away’ units and 3 months for all auxiliary parts.
SHIPPING / LOGISTICS:
The Differential will be shipped directly to you on a half pallet, please observe how the Differential is secured and fastened to the pallet. This will help you when it’s time to return your old Differential.
Shipping price advertised is for a one way shipping to your desired destination, and does not include the Collection of your old Differential. This can be arranged at an extra cost.
UK Mainland Shipping is covered.
Scottish Highlands and Northern Ireland post codes available at an additional cost.
SURCHARGE:
The surcharge is additional to the purchase price, therefore it is required before the Differential is shipped. The surcharge amount is £350 and maybe refundable once you’re old Differential is received.
The old Differential needs to be unmolested and serviceable, what this means is that the Differential needs to come complete not stripped or dismantled, and must have no holes or damage to the case.
If your Differential is leaking oil from the case or has no drive, then its safe to say that the Differential is most likely non serviceable. In this case the £350 surcharge will not be refundable.
EXCHANGE PROCESS:
All Differentials are sold on a exchange basis, therefore your old Differential is required, the exchange process is designed in away to make it convenient for the buyer. Once the new gearbox has been received simply refrain all packaging and securing fixings, these will assist you when returning the old Differential. The return of the old Differential is at a cost of the buyer, it is the responsibility of the buyer to return the Differential in a safe and secure method with the packaging provided.
(The exchange process can be handled by us for an additional cost, usually the same price as the shipping to you.)
DEPARTURE:
All Transmissions are bespoke and built to order, there for there can be down time before the Differential is shipped. We aim to get most Differentials shipped within 3 days of the purchase date.
(This can be extended considerably if the Differential is a bespoke item and requires a build slot.)
OPENING HOURS:
Our workshop hours are 9.00am – 5.00pm Monday – Friday and 9.00am – 1pm Saturday.
