If you have one belt that is going bad, replace them all simultaneously. You don't want to have to do this job again in the near future.
Almost every early SL Kent comes across needs new front wheel bearings. These get so neglected and hardly ever replaced. We are offering a very high quality kit as shown above that will include free grease for your new wheel bearings.
Inspect for adjustment and tension. If you disconnect the cable from the throttle linkage and there is no spring back pressure then the cable is broken.
New o-ring seal installed.
This accumulator was unique in the mid to late 1970s. It was used on all 6.9s but only some 450 V8 models. That is why you MUST know which type you have BEFORE ordering. You can clearly see the two threaded holes coming into the front of the accumulator housing.
Almost NLA. As a safety preventative measure, replace this hose if it shows signs of hardening or cracking. This hose is under 90 psi; if it cracks and spews fuel, you can have an instant engine fire.
30 light bulbs total in this assortment. PLEASE NOTE: These may not be every bulb you will need for every model, but you will have extras on hand. These cars are OLD, and most of the bulbs need to be replaced. They even start to loose some of their intensity over time.
High quality fast break in pads with special coated anti-squeal pad bonded to the back side of the pad. We include 4 new sensor wires and a small ceramic brake pad grease to lube the pad edges and the pins. ( no need to lube the back side).
These plugs will NOT work on your original injectors. They will ONLY work on our new replacements (see below). These plugs are a good alternative to the damaged originals on your D-Jetronic fuel-injected engine only if you are installing our new injectors.
This is what you need as the final touch to get your later 450 engine to run smoothly. New Distributor cap, Bosch or Bremi rotor, and new Bremi wires. If you need spark plugs as well please order separately. See related products below
New tensioner as shown. No specific instructions are available but this can be installed from outside the engine once you get access the the hold down bolts.
This video applies to both K-jetronic and KE-jetronic fuel injection engines on Mercedes from 1976 to 1993.. Let's say you just acquired an old gas engined Mercedes and you just can not get it to run right and or even get it to start.
Nice to have a few extra 13mm sockets around. This is the first tool that gets lost when working on old Mercedes. The tall shoulder inside helps to hold the nut or bolt in a position to make it easier to start the threads.
Think age here. Many of these shifters on our classic Mercedes are starting to get loose inside the shifter, and when the old bushings fail, you will get a lot of slop side to side when you shift between gears. Note: These bushings are different from the bushing that go on the shift levers.
This is a great kit for your 350SL, 450SL, 450SLC, 380SLC, 380SL, and 560SL from 1972 to 1989.
The leads are black and red and three feet in length. The alligator clips can be removed to give you other options on how you use them.
These are the critical seals that go on the D-jetronic fuel injectors. If they leak air, your engine with idle high, start poorly and run lean, which can damage the pistons. We recommend you replace these whenever you remove and replace the injectors.
In this 13-minute CIS training video, Kent will walk you through the steps recommended by Mercedes Benz to fully test the operation of the EHA valve on 1984 to 1993 4, 6, and 8-cylinder engines with KE-jetronic fuel injection.
This high-quality meter can test all types of automotive electrical circuits, but Kent has discovered it is particularly well suited for testing Bosch KE jetronic fuel injection components on those CIS models from 1984 to 1993.
Often rotten and torn. Replace with new when working on your fuel delivery system. PLEASE NOTE: These are included when you purchase any of our fuel pump delivery kits.
Replace your old and worn knob with this inexpensive genuine Mercedes part.
After completing the pressure test on your CIS engine, you discover a problem. But how can you find out how to isolate and fix it? This is going to require some research on your part. Start by learning how the system works and how each component plays a part.
In this video, you will see how the gauges are hooked up to a 560SL and how the pressures are read. The length of this 30-minute shows the detail Kent has put into filming all the critical components of doing a KE-Jetronic fuel system pressure test.
This video is specific to K- jetronic fuel-injected engines from 1976 to 1985. This includes the 350, 450, and 280 engines in the R107, W116, W123, and early W126 gas Mercedes. In this 29-minute video. Kent will show you how to hook up the gauge, run the fuel pumps, and complete the test.
There are a few factory recommend procedures and tests you should do before you do an actual pressure test on a CIS fuel-injected engine. In this 20-minute training video, Kent will walk you through these procedures step-by-step.
To do proper system testing on CIS fuel injection, you must find a way to get the fuel pump or fuel pumps to run continuously without the engine running. This can not be done by just using the ignition key. In this 15-minute training video, Kent will show the options available to do this.
This video will help you decide if you want to try to do a fuel pressure test yourself. It is a fairly simple DIY job but will all the confusion and misinformation on the internet; one would believe it is a complicated process that is hard to understand.
6 black plastic clips as shown. Have these on hand any time you need to remove the two vent grills under the windshield
These will fit W108, W109, and W111 with the very early 3.5 V8 engines only. WARNING: MAKE CERTAIN your current injectors are yellow at the top. A restocking fee will apply if you pl
Let's face it. These fuel tanks and now 50 years old and most are not squeaky clean inside. There is a fuel tank screen that will catch most particles if the screen is in good shape. But I have found that it will not catch the very fine rust particulates that are so common in these old cars.
PLEASE NOTE: Wire color may be all red or all black (depending on stock on hand) .
As of early April, 2026, Kent has decided to revise his fuel-system pressure-test kits. New versions will be more engine-specific and include additional features to help you conduct thorough, accurate tests of your fuel injection system.

People call these two units pressure regulators, but really only one of them is. In this xx minute video, Kent will explain how these are different, what each one does, how to adjust them, and how to test them with a hand pump vacuum tester.
In this 8-minute video, Kent will show you how to quickly depressurize your D-Jetronic fuel system before doing any injector service, replacing any hoses, or hooking up our fuel pressure tester.
In this xx minute instructional video Kent will walk you through the process of hooking up the gauge, taking the proper readings at idle and at rpm, adjusting the regulator, checking for internal leaks, and depressurizing before removal.
In this 12-minute instructional video, Kent will show you how he installs the rear hood seal on the hoods of the R107 and the C107 built from 1972 to 1989.
Very important part for fresh air supply any time heater or ac is running.
This procedure is necessary when you install a new master cylinder or allow fluid to completely leak out of your master cylinder.
In this 30 minute instructional video Kent will use a 1972 300SEL 4.5 to show you how to remove the master cylinder with minimal spillage, how to install the tank and bench bleed a new master cylinder, and how to reinstall it with minimal brake fluid spillage while protecting your car's paint.
These will also fit the 1972 U.S. version 350SL with the 4.5 engine. Just make sure of the correct color. WARNING: MAKE CERTAIN your current injectors are blue/green at the top. A restocking fee will apply if you place an order in error. These are for the 4.5 engine only.
Here is a 15 minute video that can really help you if you have small coolant leaks around your idle air valve. You will learn how easy it is to break the bolts when removing this valve, and your option to fix it.
In this 14 minute instructional video Kent will demonstrate how to remove and install a new thermostat in a 450 engine. Here you will see how tight it is to get install in a 300SEL 4.5, but other V8s will have better access.
In this 12 minute instructional video, Kent will demonstrate how to remove and replace the viscous fan clutch in a 1972 300SEL 4.5. Other topics covered will be cleaning and corrosion prevention. This video is included free with the purchase of our fan clutch install kit ( see below).
This covers power sunroofs on the W111, W108, W114, W115, C107 (SLC), W116 (including the 1980 W116 sedans) and the early W123 (1977 to 1979). Are you dealing with any of these sunroof problems? Stuck roof, broken drive gears, bad cable, no lubrication, brok
In this 33-minute instructional video, Kent will show you how to convert your old points ignition to an efficient modern electronic ignition. Rid yourself of those old high-maintenance distributor points forever.
This is one part that is very subject to corrosion and leaks around the base. When the actual part fails, included our new stainless bolts that won't corrode with instructions on how to carefully get the old corroded bolts out.
Most of the older 450 engine fan clutches are still original on most of the older unrestored V8 models from 1970 to 1980. If you are having problems with your 450 V8 running hot check the friction in your clutch. They are often worn out as they seem to never get changed.
This is seldom replaced. If you engine is taking over 15 minutes to get up to full operating temp then your thermostat is probably worn now. We got you covered with kit. We will get you the extra hardware, supplies and video instructions so you have the confidence to do this job yourself.
