smg hydraulic pump rebuild manufacturer

Renew your worn or burn"t out SMG pump with our remanufactured units! Our remanufactured pumps are disassembled, thoroughly cleaned and reassembled with all new components.

Pentosin CHF 11S is a synthetic high performance hydraulic fluid for life-time application in modern vehicle aggregates. Pentosin CHF 11S is especially designed for hydraulics in the automotive industry with the highest technical requirements such as in: power steering, level control, shock absorber, hydro-pneumatic suspension, stability and traction control, hydraulics for convertible tops, central lock systems, etc.

BBA-Reman can repair your BMW SMG Pump. This is far more than just a motor replacement and involves the re manufacture and testing of the entire unit. For M5 and M6 SMG units we are able to offer a repair service, whereas for the more common M3 SMG units we also offer an exchange service for those wanting to get their E46 SMG’s back on the road with little to no delay. We also offer a repair service for the rare BMW SSG pumps.

The BMW M3 SMG pump is a self-contained unit with a motor, pump, solenoids and pressure accumulator. The M5 and M6 Getrag units are a similar setup, albeit in two units, linked hydraulically.

In most cases, the reason for this is the worn electric motor that drives the hydraulic pump in the hydraulic unit. In addition, the gap losses in the hydraulic system increase enormously at high temperatures .

The worn out original motor is exchanged for Burkhart Engineering"s "Plug & Play" replacement motor. The new motor is equipped with the required pins and seals and can be pinned directly into the original BMW wiring harness. This motor is OEM quality and help you to aviod the alternative of having to buy a new hydraulic unit worth thousands. The Burkhart Engineering SMG unlocking tool greatly simplifies the replacement of the electric motor of the SMG II hydraulic unit and allows pins can be pushed out to the rear without damaging the connector or pins.

Further to this, the hydraulic unit may no longer be able to keep up with the pressure build-up. Burkhart Engineering have developed their own high performance hydraulic oil which will keep the pressure built up and react as much as 25% faster than with normal Pentosin CHF 11s.

Do not operate the motor outside the hydraulic unit. Furthermore, the engine should not be dismantled again after it has been installed. The tight fit of the motor can damage it when it is removed.

The repair kit can only achieve the desired improvement in an otherwise fully functional unit. If, for example, the piston accumulator has a defect or no longer has the required preload pressure, this must also be replaced. The "salmon" SMG relay (BMW part number 12631742690) is also highly recommended to be replaced.

Burkhart Engineering, based in southern Germany, is a BMW specialist renowned worldwide for its expertise with the E46 M3 SMG2 transmission system. Through countless repairs and a refreshing approach to the problems the SMG system can present, Burkhart has since developed a range of rebuild kits and upgrades to make SMG ownership a worry-free experience.

The Burkhart Engineering SMG Hydraulic Pump Repair Kit can not only repair your pump, but also improves it to be ready for high temperature track use, traffic jams and hot summer weather.

In most cases this is caused by a worn electric motor, which drives the hydraulic pump in the SMG unit. Further the gap leakage in the hydraulic system increase massively during high temperatures. If additionally many hydraulic consumers are working (clutch slave cylinder and gearbox actuator), the hydraulic unit no longer produces enough pressure – for this issue Burkhart Engineering High Performance Hydraulic Fluid offers a huge improvement.  The pump runs on pressure up to 25% fasterthan using the conventional Pentosin CHF 11s.

The old motor can be replaced by the new one as a plug and play swap. The replacement motor is equipped with the required pins and seals and can be directly installed with the original wiring loom. These are brand new spare parts in OEM quality –  the alternative to save you from buying a complete new SMG hydraulic unit.

This Repair Kit only works if the rest of the hydraulic unit is functional. The accumulator for example needs a defined preload pressure. Should this not be the case, the accumulator has to be replaced, too. In Burkhart Engineering’s SMG-Wiki you can find instructions about how to check the preload pressure in the accumulator.

This part is listed by BMW as BMW part number 21532229715 (21-53-2-229-715) and is described as a rebuilt SMG Hydraulic Pump with Pressure Accumulator for E46 M3.

The SMG pump on the SMG (sequential manual gearbox) equipped E46 M3 is a very well known failure point. It"s really not a question of IF your SMG pump will suffer a failure, but when. Typically, the SMG pump lasts somewhere in the neighborhood of 100k miles, but they have been known to fail with much less miles.

This is a rebuilt SMG pump with a new electric motor. The assembly has been rebuilt MLR Engineering - experts in SMG and hydraulic pumps with over 30 years of experience and their own tried and proven solutions to SMG problems.

A core charge applies to this purchase. The $450 core charge is included in the price shown. The supply of original parts for rebuilding keeps the final purchase price low. The core must match the part that was supplied in terms of fitment, type, application, accessories, and hardware. Damaged or modified cores will not receive a refund. A core charge can only be refunded once the core has been inspected and approved. Click here for our Core Policy.

In most cases the reason for this is because of worn electric motor, which drives the hydraulic pump in the hydraulic unit. In addition, the gap losses in the hydraulic system increase enormously at high temperatures. If many hydraulic consumers are now active (clutch slave cylinder and transmission actuator), the hydraulic unit can no longer keep up with the pressure build-up. We have ours for that Burkhart Engineering High performance hydraulic oil developed. The required system pressure we up to 25% faster built up than is the case with the normal pentosine CHF 11s.

The worn original engine can "Plug & Play" exchanged for our repair engine. The replacement engine is equipped with the required pins and seals and can be pinned directly into the original BMW wiring harness. It is a replacement part OEM quality. The alternative to avoid having to buy a new hydraulic unit.
