Custom made hydraulic cylinder seals for Mercedes


I was tired of trying to find high quality seals for my three 500SL's / R129 after the cylinders were already leaking after being rebuilt in April of 2008 (Nov 2012).


After over a year of research tried to find a maunfacturer in the US, only one would quote a price @ $35.00 each seal in quantity, and could not manufacture the smallest one. Tried having manufacturers in China that ended up being a huge waste of time and money, NONE of the seals were the correct size OR material.


I found a manufacturer in Europe that makes seals to my specifications (As a machinist since 1980 I have personally made very high precision parts for the Aerospace industry, and 3 out of the 4 seals are Non-standard size) out of a material that far exceeds the OEM and more than one well known rebuilder.


WARNING: No, you don't want to use some cheap ebay O-ring kit, they can't handle the high pressures, and are not made to seal moving parts.

If you have your cylinders rebuild from ANYONE, ensure they actually used the proper U-cup hydraulic profile, and proper material, they simply are the only seal that can handle 2000+ psi pressures of your hydraulic system.


I have all r129 top cylinders in stock and ready to ship for part numbers:


1298001672 (2- Windshield front lock cylinders)

1298002172 (2- Rear top lock cylinders)

1298000272 (2- Main top cylinders)

1298002072 (2- Tonneau cylinders)

1298000072 (Rarely used on some Rear top lock cylinders)

1298000072 ( 2- Tonneau lock cylinders 1990 -1996, only uses left side 1997-2002)

1298001772 (1- Left top bow cylinder)

1298001872 or 1248000272 (1- Right top bow cylinder)


Yes,  If you can remove them, you can rebuild them yourself.


You do need to be very careful not to scratch the piston rod, and DO NOT use a pliers/vise grips on the piston rod.


Never, ever use any hydraulic fluid other than MB hydraulic top fluid, EVER. Unless you want to replace the pump, solenoids and lines!


Here's a nice video removing, rebuilding and replacing the windshield top lock cylinders>>>

Full sets now INCLUDE special pin tool to remove rear bow seal retainer.


Currently I only have 2 full sets available for r129's:


These kits are designed for  Mercedes R129 years:

1993 - 2002 Mercedes-Benz SL280

1990 - 1993 Mercedes-Benz 300SL

1990 - 1993 Mercedes-Benz 300SL

1994 - 2002 Mercedes-Benz SL320

1990 - 1993 Mercedes-Benz 500SL

1994 - 2002 Mercedes-Benz SL500

1993 - 1993 Mercedes-Benz 600SL

1994 - 2002 Mercedes-Benz SL600


I don't sell single seals, when you replace one, the opposite side usually quickly starts leaking because it can't handle full pressure like the new one.

Hard to find Mercedes parts for sale:


Mercedes OEM aluminum cam oilers to replace the plastic ones that fail on 1993 and up M119 engine.

When these fail ( plastic cap pops off the end and oil leaks out).  This is a major cause of ticking and ruined cams, valves, lifters etc.

Mercedes ONLY sells the same crappy plastic oilers, why would you replace the with the same plastic crap?

These lifetime aluminum oilers cost less than the plastic, or a lot less than aftermarket aluminum.  These are used oilers that are throughly  ultrasonically cleaned and include new correct o-rings.

Part number  1191870087 - 119 187 0087 - 119 187 00 87


Used upgraded Mercedes engine wiring harnesses - all harnesses are rewrapped/repaired as needed, any broken connectors are replaced.


All new model cars from 1992-1995, some 1996 have "biodegradeable" wiring insulation that will fail. This causes all types of no-start, stalling, rough idle, limp home problems.

Starting in 1996 mercedes upgraded the wiring harnesses, this time they used high quality insulation.

Even some early 1996 OEM replacement harnesses used defective wiring!

I only sell used upgraded engine wiring harnesses manufactured after 1996, these are engineered to last the lifetime of your car. All harnesses are rewrapped/repaired as needed with broken or missing connectors replaced and checked end to end on every wire to ensure conductivity.


WARNING: They also used the same eco-junk "biodegradeable"  insulation in the lower engine harness - (oil pressure gauge starts acting up),and the ETA / throttle body - contact BBA to rebuild


You must check your current parts tag to order correct harness, DO NOT rely on the dealer or parts catalogs!
