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 and a half of research 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 at least 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:

Set of 12 for 1990-1996   

Set of 11 for 1997-2002   

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 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.

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.

They also used the same eco-junk "biodegradeable"  insulation in the lower engine harness and the ETA (electronic throttle actuator). 

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

I usually stock the following wiring harnesses:

c280              2024407905,  202 440 7905

S600 / SL600 1405404705, 140 540 47 05  - All v12, I usually have at least 1 available, you may also need the under hood body harness, this harness is highly susceptible to heat due to close quarters. I do have one! I also harve throttle bodies (ETA) for v12's.

*** Twice in May 2014 Mercedes dealers were WRONG on the actual wiring harness used on 2 different 1994 / 1995 e320, DO NOT rely on your VIN number for the part you need, email me for parts tag location and pictures.

One full set of five Mercedes lightweight "steelie" Aluminum  Wheels 

W113 W121 280 SL 113 14" x 6"  rims                                   set  of 5

Lemmerz 1465-3 / MB  part number 1234001502 

Each wheel weighs 11 pounds, which is approximately a 12 pound savings per wheel in un-sprung weight as compared with the equivalent steel wheel.  Note:  these wheels are the extremely rare 6" x 14" wheel (in contrast to the more common 5 1/2" x 14" wheels).
