Hydraulic Pump - R129 SL-Class 1990-2002
There are two options for placing your order:
1. (Most affordable) You send in your malfunctioning R129 Hydraulic Pump, and Top Hydraulics rebuilds it.
- The rebuild includes electric motor replacement or rewinding if necessary, service of hydraulic valves, and upgrade of internal seals in the pump to eliminate current or future pressure loss or internal bypass. Three years warranty.
OR
2. (Fastest) Expedited Core Exchange Option where Top Hydraulics ships parts from our inventory first
($500 plus a $200 Refundable Core Charge).
- Option 2 means that you get a rebuilt & upgraded pump from Top Hydraulics' inventory first, then you ship back your original part for credit of your $200 core refund. Top Hydraulics ships the pump as pictured. You get a pump that has been rebuilt to outlast and outperform OEM.
Please note: Model year 1997 is a transition year and may have the earlier version pump P/N: 1298000748, or the later version pump P/N: 1298001448 used from late 1997 through 2002. The later version pump is more complicated and costs an additional $100 for rebuild & upgrade service.
Rebuild service includes upgrade of internal seals, relay replacement, service of filters, service of pump gears, service of electric motor, service of solenoid where applicable, and replacement of pump gears and/or electric motor and/or solenoid if necessary. Extensive bench testing ensures your pump exceeds OEM factory specs before we ship the pump back to you. This includes pressure test, flow test, and extended load test.
Some applicable pump part numbers are:
A129 800 00 48 aka 1298000048
A129 800 05 48 aka 1298000548
A129 800 07 48 aka 1298000748
A129 800 14 48 aka 1298001448
A124 800 23 48 aka 1248002348
Special arrangements may have to be made for abused pumps (such as victims of floods or fire or previous repair attempts).
If you select optional core exchange, please note: The pump ships with reservoir filler cap or vent (as applicable to the model number), with mounting frame, and with relay. There are several versions of hydraulic pumps for the R129 SL-Class, and they are generally not compatible with each other. Please verify the part number on your pump, such as 129 800 00 48, 129 800 07 48, 129 800 14 48, or similar. Top Hydraulics will ship your pump once you have given us your original pump's part number. The core refund will be reduced or retained if there are parts missing, or if there is significant damage from abuse on the core, such as results from DIY repair attempts or severe corrosion.
Shipping is in a USPS Priority Mail Large Flat Rate Box, and the domestic shipping charge is $20.

For Customs clearance, you must declare a value on the package you are sending us. Please note: parcels with a declared value under US$750 enter the US without incurring taxes, duties or clearance fees. Considering that you are sending us broken parts for repair, it is most reasonable to declare a value under US$750. You can insure your parcel only up to the amount that has been declared as the value for customs, so your best insurance is good packaging. It is extremely rare that parts get lost on the way to us.
Please be sure to drain or cycle all fluid out of your parts, then wrap them in plastic, so that the parcel does not get soaked in oil. It is generally a good practice to double box pumps or sets of cylinders because heavy parcels take quite a beating in international transit unless you are using a premium carrier such as FedEx. Clearly, you don't want to just stick a part into a cardboard envelope without any further protection or buffering. Buffer your parcel well inside so that parts don't rattle around or the parcel gets crushed from others on top of it. Ideally, tape all around all surfaces of the parcel, which generally provides excellent protection against losing components that are trying to escape through small holes in the cardboard.
We use FedEx International Priority for almost all outbound international shipments, as they tend to offer the fastest and most secure service. Due to our shipping volumes, our rates for return shipping your parts via FedEx International Priority are typically equal to or cheaper than Postal Service. We cannot offer shipping labels for your shipment from you to us - you will have to shop around for the best option to ship your parts to us.
In the rare event that you feel you have to declare a value over US$750 on your parcel shipping to us, please understand that we will need to be reimbursed for any importation fees or duties incurred. You agree to this by accepting our terms and conditions when you place your order. On high value parcels, we are typically charged an Entry Prep Fee (currently about $25) plus 2.5% tax on the declared value of the package, there are oftentimes delays in customs, and it can take a while for us to receive the actual customs invoice.
Depending on the parts you are sending us, your customs declaration might say "hydraulic cylinder for repair" or "hydraulic pump" for repair. Please note that DHL does not like to carry hydraulic parts or used car parts in some countries. If your carrier asks for the "harmonized code or tariff" of the parts you are shipping, those are 841221 for linear actuators (cylinders) and 841360 for pumps.
At Top Hydraulics, we pride ourselves on providing new and remanufactured parts with unmatched quality and longevity.
It is very rare that our parts fail. Obviously, we are only human and we could have made a mistake or one of our components might indeed have had a hidden defect. Please contact us first when you suspect that you have a warranty case, so that we can try to help right away. It could be that the failure you are experiencing is caused by a different component or that the installation was not quite proper, so we like to be in touch first to go over the situation with you.
Unless stated otherwise, there is a 3 year warranty on all new and remanufactured parts provided by Top Hydraulics. This warranty is transferable. All parts manufactured or rebuilt by Top Hydraulics have unique markings, so there is no additional paperwork needed to transfer a warranty. The warranty does not cover labor, direct or consequential damages. The warranty is void when the parts have been abused or have been installed incorrectly, or when brake fluid or stop-leak additives have contaminated your hydraulic system..
You will have to send your failed part(s) back to Top Hydraulics for a warranty evaluation. In the extremely rare case of failure on rebuilds or new parts shipped or provided by Top Hydraulics, Top Hydraulics' warranty covers only parts and is limited to rebuilding the products previously shipped by Top Hydraulics, or replacing them, or refunding the rebuild fee at Top Hydraulics' discretion. If the failure was our fault, then we will refund reasonable shipping costs, as well.
