STC100 SVO conversion.
NOTE: This is custom-built in our shop after an order is placed. PLEASE ALLOW 5 to 7 working days before it can be shipped. Alternatively, you can order the "UNIVERSAL KIT" which is in stock for immediate shipment. You can assemble this yourself as it yields the same results and save $$$.
The B1 piston assembly is not easy to remove and then reinstall. Because of the length of the two big springs behind the cover, it takes a tool that has a lengthy throw.
We modified this slide hammer puller set in our shop so it will work in removing two key components in the 722.3 and 722.4 automatic transmissions. Getting the B2 piston and sleeve out of the case can be a real bear without this tool. With it, it comes out quickly and easily.
You will need a 12-point DEEP socket. That is the only thing that will work. Most impact sockets are six-sided. The best way to remove this nut is with a big impact wrench with the transmission locked in park. So you will need a quality heavy-duty socket. This one is made in the U.S.A.
Take a very close look at the picture. These are all the gaskets and seals you will need to replace if you open up your 722.3 transmission that was produced from 1981 to 1990 for all 6 and 8-cylinder passenger cars that had a displacement of 3.0 liters or more.
This piston is not new. The outer sealing ring has been replaced, and the shaft polished. It is in excellent condition. This will work on the 722.3 transmission, but NOT the 722.4 smaller transmission found in some 1985 to 1995 models. The piston diameters are different.
These are the additional components required to run your old Mercedes diesel on dual tanks (DTC) when using Kent's conversion kits or methods.
Fits 300D, 300TD, 300CD and 300SD from 1981 to 1985. Hard now to find good ones. This is the only one we have. This is the actual part you will receive.
HUse this wiring adapter Kent designed to connect to one of the fuse posts in your fuse box to give you a "keyed" on-and-off power source for an electrical component you wish to install. The video below will give you more details.
FITS 1981 to 1985 5-cylinder W123 engines ONLY. Not "perfect" but above average used condition.

Excellent used clean switch as shown for late 300TD. This is the actual one you will receive. New bulb installed. BUSTER
GOOD working part as shown. Holds a strong vacuum. You will need to use your rod and cover lock to make this work.

Fits 1981 to 1984 300TD turbo and 1982 to 1984 300D and 300CD and 1981 to 1984 300SD with air filter mounted on engine. This is the actual part you will receive.
When it is time to change the rear end fluid, why not get rid of your old rusty drain plug(s) and replace one or both with stainless steel plugs?
This only applies to Mercedessource conversion kits installed or being installed on the W116 300SD, all W123 diesels, and the 1981 to 1985 W126 300SD. In this xx-minute instructional video, Kent explains the hose routing you will have to change, the extra hoses you will have to add, and the fuel
Good connector with soft rubber. Not cracked. See the picture below to show the location.
In this 15-minute on-demand video, Kent will explain how to use his injection pump de-gunking kits to clean out an old pump and to check the flow rate between each delivery valve. Watch the YouTube short video below to get an overview of these kits.

If you are a diesel enthusiast, these are a must-have for your collection. These have become rare and hard to find in this condition. Not perfect, but above average. These will teach you the basics!
This is a must-have tool if you own a 1970 to 1991 M116 or M117 V8 engine. It will also work on older six-cylinder gas and four and 5-cylinder engines from the 1960s up through 1985. Note: The included video instructions only cover removal and installation of the pin.
Very hard to find in good condition. This came off an 85 wagon with a trap oxidizer, air filter mounted off the engine behind the right headlight, and fluid tank for the SLS mounted on the left side of the engine compartment. The hoses are longer than the standard 1981 to 1984 turbo wagons.
ONLY one available. New as shown.
Kent's instructions for replacing the real seal in this style pump. Make sure your pump is all aluminum ZF pump, or this seal will not work. Total run time: 14 minutes. An 8-inch C-clamp will be required to complete the installation.
A BIG C-clamp like this is pretty handy to have around your shop, but it is a must if you plan to open up your 1980s-era ZF aluminum power steering pump.
Good working parts as shown. Oil pressure unit has been REMOVED. PARTS ONLY.
This 10-minute by Kent Bergsma will help you install an oversized filter mounted on an aluminum bracket in the engine compartment of your old 1977 to 1985 Mercedes diesel for the purpose of running vegetable oil. This video is included free with the purchase of our kit below.
These 8-minute video instructions are now included with Kent's basic and deluxe Version 3 fuel injection pressure tester. You will learn some tips and tricks on how to pressure test a 1976 to 1985 fuel-injected V8 engine using one of our test kits.
The front and rear seals in both the manual and power sunroofs are the same, but the procedure to remove and replace the sunroof panel differs.
This is the actual part that will ship. We will include a new block mounting gasket and new cap shaft o-rings. BUPS
See below for excerpts from these pdf download instructions:
We have only seen one of these, and it came off a 150,000 mile 1977 240D. I am sure it would fit the 1978 and 1979 240D, but it would not be original. Study the pictures carefully. Note the different cap designs with long center bolt. BUPS
These instructions are specific to the axle boot replacement kit we sell but can also be "generic" in application to most models with rubber axle boots. They come as a PDF in a 2-up format.
The original hex bolts are soft metal, and they round out easily. This makes it slow and tediously to adjust your door strikers. Torx is much better than Hex! Old Allen has passed on...
You will need a Torx T45 bit to install these.
Often not done, but you will regret not adding this correct SACHS grease to you clutch input shaft splines! Regular grease with not stand up over time.
A high quality bearing. It is a good idea to replace this anytime you have the transmission. Remember it spins a lot!
In this short 3-minute video, Kent will show you a trick that few know about. You can get those tapered shaft ball joints ( like to find on tie rods and control rods) loose without damaging the rubber boot. It can be faster and less painful than using traditional methods.
This is a very common failure item on the OM617 turbo diesel engines. There are two reasons why it bends or strips. 1) The original threaded adjusting rod is made of a VERY soft metal.
Kent has come up with a new repair kit that will permanently fix your sagging and sloppy inside door pulls. This applies to all W123 and W126 chassis. New ones are very expensive if you can find them. Good used ones are getting harder to get.
Tired of that sagging chrome door pull on your 123 or 126? My new kit will fix this problem permanently, and the handle will be better than when it left the factory. Watch the video below and Kent will explain what is in the kit and give you a before and after demonstration.
WARNING READ CAREFULLY: If your vacuum pump recently broke apart there may be a reason for it other than just a vacuum pump fatigue failure. When these pumps break up inside there is usually a problem with the drive mechanism inside the diesel engine.
H4 headlights are still brighter ( see below) but these are your best option if you are on a budget. Easy to install. Video instructions included.
These are actually a little brighter than the originals, and they look correct on the older Mercedes.
Now, you can put newer style "pencil glow plugs" in your early W123 300D 300CD and 300TD by following the instructions written by Kent Bergsma. Kent walks you through the process, explains some of the pitfalls, and winds up showing you the finished product. These are the instructions.
Buy the tools with the variety pack of LED dash bulbs and save $$$. Included are 2 bright white, 2 amber, 2 red, and 2 blue bulbs. You will receive video instructions on how to use the tools and how to change the bulbs. Watch the YouTube video below to get a quick overview.
To read or download in a 2-up format. Kent will walk you through the steps of adjusting the valve clearances on your older 190D, 200D, 220D, 240D, 300D, 300CD, 300TD, and 300SD. This procedure should be done every 12,000 miles. Two special wrenches are required.
