On the M112 V6 and M113 V8 engines this is the most common failure item that can leave you stranded. Better to replace it with an improved new part BEFORE your engine quits cold.
Diesel idling too fast. Diesel idling too slow. Diesel shaking at idle. Transmission jerks with shifting from Park to Drive. These are some of the symptoms that might indicate your engine's idle speed is not adjusted correctly.
This is a very critical and very neglected filter located inside the fuel tank.
Since new original style pumps are no longer made, this is the best way to finally fix your old fuel pump leaks and poor performance. This kit is designed specifically for the W108 and W109 small V8 sedans.
This is an above-average used bumper, as shown. It's not perfect. Study the pictures carefully. Chrome is clean and bright, and there is no major corrosion on the front or back, where you usually find severe aluminum corrosion.

Fits all 380SL and 380SLC from 1981 to 1985. This flexible fuel hose connects the outlet of the fuel filter to the metal hard fuel line going from the rear of the 380SL to the engine compartment. This hose is hard to install and hard to inspect.
High-quality fuel filter for your later model R107 SL. With the right tools and knowledge, you may not need to drain your fuel tank to replace this filter ( replacement should be every 30,000 miles for peak performance. Watch Kent's video below for installation tips.
These are three inexpensive parts that seem to never get replaced when they wear out. If "mechanics" miss these items. Are you losing coolant? Are you losing windshield washer fluid? Do you have unsightly oil on your right valve cover?
Hard to believe we took so long to come up with this tool. It was Gerson's genius that made it happen. The secret turned out to be the hook that keeps the tool in place while stretching out the rubber donut. Wow! What a cool tool.
Best engine oil filters for your classic R107 or C107. As seen on Cherry.
This socket is the correct size to use with our R107 Fuel Tank Screen Removal Tool ( See below:). It is a heavy-walled 27 mm black impact grade socket made in the U.S.A.
These will fit all 1976 to 1991 4.5, 3.8, 5.0 and 5.6-liter V8 engines with Bosch C.I.S fuel injection.
Do not let anyone convince you to install some super platinum, iridium or kryptonite spark plug in your SL V8. They are just not capable of handling the richer fuel mixtures associated with these older engines.
Socket is now black (impact grade). This is a tool that Kent first thought about making 20 years ago. While installing shock absorbers in his 380SL he had finally had enough - so it was back to the machine shop to come up with a new tool.
The R107 and C107 plastic shift bushings are very common parts that need to be replaced more often than not. Can you believe it is the exact same part that was used on all models for over 25 years! It is an inexpensive part that can cause big problems if it breaks out.
For many years, we were receiving frantic requests from customers asking for help with removing the fuel tank filter screen from their 1971 to 1989 350SL, 450SL, 380SL, 500SL, or 560SL (the same issue also applies to all SLC coupes). Until recently, we did not have a solution other than to tell

Improve the ride, handling, and safety of your 1986 to 1989 107 SL convertible and coupe. Yes, shocks play a big part in safety and people often do not know this. Old shocks just wear out slowly so you may not "feel" the problem until you install new Bilsteins!
Improve the ride, handling, and safety of your 1972 to 1985 107 SL convertible and coupe. Yes, shocks play a big part in safety and people often do not know this. Old shocks just wear out slowly so you may not "feel" the problem until you install new Bilsteins!
These are very high-quality brake pads and fit many different models. Brake pad paste included. Watch the video below to see why these are Kent's favorites.
These are simply the best for your old Benz. They fit all W126 300SD and R107 380SL from 1981 to 1985. They also will fit the W126 380SE, 380SEL, and 500SEL from 1981 to 1985. Very heavy to ship. Watch the video below to see why these are Kent's favorites.
Newly rebuilt driver and passenger side front calipers WITH NEW CERAMIC ( low dust ) brake pads. Fits all W123 chassis 240D 300D 300CD 300TD 280E 280CE 1977 to 1985. Please note there is NO HASSLE CORE CHARGE.
Works on the following: 6 cylinder gas MFI engines 1959 to 1972, 6.3 and diesel engines 200D 220D 240D 300D 300TD 300CD and 300SD through 1985.
You want superior stopping performance as well as minimum brake dust on your wheels - then these pads are what you want. Watch the video below - they are also really pretty! :-)
Watch the video below to see how this special wrench is used on the three nuts holding the exhaust downpipe to the turbocharger exhaust flange.
When replacing the thermostat in your order diesel you may end up fitting a lot of corrosion. This kit will help you make sure you do not have any leaks when you install the new thermostat and will prevent corrosion of the housing bolts in the future.
This driver-side tail light is the best we have seen. No crazing, fading or cranks in the lense and the chrome is excellent. ALL METAL (not plastic) reflector and good used soft rubber seal included.
If you are experiencing minor coolant loss on your older model that has the cap on the radiator, it may because you do not have the correct cap. Not all caps are created equal as Kent will point out in the video below:
This is the type of radiator that will require this cap.
This is a hard-to-find adapter that will need if you have one of the early 1990s 5 and 6 cylinder turbo diesel engines. We machine this right here in our shop and it is designed to work directly with our OM61x compression tester ( see related products below):
Have you ever had a hard time finally a very small coolant leak? Do you find yourself adding small amounts of coolant but can not see any leak? Is there a funny smell coming from inside your Benz when you run the heater?
Kent jokingly mentions this has become a late W123 epidemic! You see this problem happening on all late model 240D, 300D, 300CD, and 300TD wagons.
This easy-to-install kit could do wonders for your older diesel engine. The lift pump is almost always forgotten when it comes to maintenance on the OM616 and OM617 engines.
It is a good working and tested unit, as shown. I believe the mounting plate is for an early W108 or W109. To fit your car, ensure you have three wires going to the unit. A brown wire will be attached to the bracket. The rubber coupling between the motor and drive unit is in good condition.
BACK IN STOCK!!! JUNE 2023
Kent has sourced 2 special Viton o-rings for the outer pump housing on these early djetronic Bosch electric fuel pumps. There are two orings that harden with age causing the pump to leak fuel at the outer end of the pump.
This kit includes two pump motor seals and two silicone plugs for the extra hole (if needed). Some tanks have only one pump, some have one pump and one plug, and some have two pumps. So we give you two or each for any combination you may run into and you may end up have a spare or spares.
Many uses for this quality hard steel tool including removing W123 and early W126 motor mount bolts.
This is a perfect fit for the O.E. copper sealing ring. You only need one but we sell these as a set of two so you will have a spare.
This is where this sealing ring is located. On top of the fuel injection lift pump and at the base of the hand primer pump:
This is a "must-have" kit when adjusting release "pop" pressures on older diesel mechanical fuel injectors. It is the internal spring "shim" thickness that determines the exact pressure required for the release of fuel at the tip of the injector.
Very high-quality steel. Original Napa branded.
This tool will allow you to remove a cylinder head pre-chamber on a 1990 to 1991 350SD 350SDL (126 chassis), 1990 to 1993 300D 2.5 (124 chassis), and 1992 to 1995 300SD / S350 (140 chassis). The special black fitting attached to the slide hammer is custom made in our shop.
On a regular basis, Kent and Gerson custom make tools to make certain jobs go easier and faster. So is the case with this long reach ratchet. It was developed to get glow plugs out of the older diesel engines without having to remove the hard lines.
This is our complete kit for an at-home DIY repair. Loose and worn out guide rod ball joint bushings are the most common front suspension problem on the W126 sedans and coupes. Check the condition of yours if you have not recently done so.
If you already have our complete repair kit and just need an extra set of seals (10) here you go. No instructions included.
You will receive two (2) five liter bottles more than enough to do a full oil change on any vehicle:
If you acquire an older Mercedes diesel and want to test those large Bosch injectors with your V3 gasoline bench tester, you will need 4 things to complete the conversion: 3000 PSI gauge, our new capture bottle to hold the larger injectors, injector sealing kit, and Kent’s written manual and vid
Please, what you see is exactly what will receive. These are mostly from OM616 and OM617 diesel engines and related transmissions and may NOT all be from the same vintage or chassis model. Study the picture carefully. Only one exactly like this.
