Works on most 116, early 107, 114, 115 and early 123 models from the early 70s up to the end of the 1970s. This is a replacement for the Bosch rectangular voltage regulator (see image below) those cars that use an internal voltage regulator.
This book explains how a parallel pre-glow system works and how to properly test it using inexpensive electrical testing equipment. If your PENCIL style glow plugs are not working properly, you need to find the cause BEFORE you start buying parts.
If your early door lock actuators do not have any cracks in the rubber diaphragms, but they just won't hold vacuum - it may be possible to fix them by taking them apart and cleaning and resealing the outer lip of each diaphragm.

This is a must-have if you have a prized Benz or any car you don't drive often!! If you let any of your cars sit for long periods ( generally over 30 days) without driving them, you can ruin your battery, especially if you let it go completely dead.
January 2019 notice: This filter is now available only in very limited quantities and may not be readily available in the future. This is why we are not able to include it in our full fluid flush kit ( See related products below) This is an often neglected filter.
When an old Mercedes ( or any other car for that matter ) has sat idle for over a year it can be a challenge to get it safely back on the road again. If it has sat idle for more than 5 years you may find it difficult to even get the engine running.
Kent modified this puller and developed a procedure to remove the front crank seal race so the job could be affordable from the DIY mechanic. This costs less than half the cost of the factory tool.
Unless the engine has been overhauled most of these old 6 cylinder gas engines of the '60s and very early '70s are running around with their original front crank seal. Take a look under your car if you have one - I bet it will look a lot like the engine in the video below.
Watch the video below to understand what this kit can do. Ensure your injection pump is thoroughly cleaned and lubricated before starting the engine after long storage.
The digital PDF instructions will walk you through the install and detailed photos will visually assist you step by step. PDF is 4 pages long.
When any part of the overboost protection system fails, your turbo diesel engine can lose power or start to smoke too much.
VERY high-quality socket as shown.
These transmission pans get "out of shape" due to over-torquing the bolts. That crushes the stops (see below), and when that happens, it is very hard to get the pan seal not to leak. Your best option if you are doing a transmission service is to replace the pan.
If you have any Mercedes model with hydraulic self leveling suspension from the early 70's up to the early 1990's this is the correct fluid to use. High quality Meyle or Febi Bilstein product. Any other type of fluid can damage the seals and score your pump.
Watch the video below to understand what this kit can do. Kent used it on his 6.3, which had sat outside and had not run in 18 years. The 6.3 injection pump is rare, to say the least, and can be very expensive to overhaul. Treat it with great care!
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):
If your transmission is shifting too soon it can really rob your car of power and acceleration. If it is shifting too late it can be very loud and annoying and even affect fuel economy.
With the long lead provided (12+ feet) you can hook up to your car battery and go around the car and test the operation of various electrical components.
If you own a Mercedes with the M116 V8 engine (expect 1980 to 1982 380 engines with single low chains) timing chain failure can really ruin your day! If the engine it turning at high speed when this happens, it can destroy the engine.
When an old Mercedes ( or any other car for that matter ) has sat idle for over a year it can be a challenge to get it safely back on the road again. If it has sat idle for more than 5 years you may find it difficult to even get the engine running.
You can save a lot of money if you can rebuild your old brake calipers, especially on some older models. If you can just get the pistons out of the housings, most calipers are rebuildable, unless they have been subject to road salt or have sat exposed to the weather for years without use.
Yes, YOU can fully drain all your transmission without using any type of "power flush." Full detailed video instructions are included. This kit is easy to connect and the process is quick and clean. Watch Kent's YouTube video below for full details.
Kent is a firm believer in using these strong magnets inside a transmission pan to help extend its useful life.
They should be placed toward the rear of the pan as shown in the picture below.
This video only applies to our injector pressure tester. Kent will show you how to attach the capture bottle and fittings to your older Version 1 or Version 2 pressure tester. Video is free with purchase of the conversion kit.
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.
Many uses for this quality hard steel tool including removing W123 and early W126 motor mount bolts.
New Fuel tank sending unit o ring. If you need to remove your sending unit to test or clean, it is a good idea to replace o-ring.
Fits 116 107 123 and 126 Chassis from 1977 to 1991.
This video will walk you step-by-step through the proper procedures for doing a full compression test on your older V8 Mercedes Engine.
Most owners do not have a big enough hex wrench to remove the fuel tank screen on those models that had the fuel tank right under the rear trunk floor. But the screen does need to be removed, inspected and cleaned due to the age of these cars.
If you own a Mercedes with the M117 V8 engine timing chain failure can really ruin your day! If the engine it turning at high speed when this happens, it can destroy the engine. If it happens at low speed, you may get away with removing the heads and replacing some bent valves.
The bowden cable runs from the transmission to the throttle linkage on many Mercedes from the early 1980's up through the early mid 1990's. When this cable fails or is out of adjustment the transmission will either shift too early or too late.
Buy a spare to carry in your trunk! FITS THE FOLLOWING: Late 107 and 116, 123, 126 up through 1991 and 201 and 124 chassis to through 1989. ALSO FITS 1990-1993 300D 2.5 AND 92-93 190E 2.6 ONLY!
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.
ALERT! ALERT! 10 years after I first started warning about this, I saw it again in my shop on Feb. 20, 2011. Seems to be happening even more now as these radiators age. I loosened up the upper hose clamp on this 123 300TD radiator and it just fell off.
This kit will allow you to replace the critical worn parts inside the early 603 U.S. made Garrett T3 turbochargers. This kit will not work if your engine has a KKK turbo made in Germany. The only way to tell which turbo you have is by visual inspection.
In this 15-minute video, Kent will show you step-by-step how to safely remove the Bowden cable without damaging it and how to install it to get the proper connection. This is not as easy as it looks, and you can break it if you are not careful.
Very good used cast iron exhaust manifold as shown. Has been painted but please do not expect paint to hold up to heat over time.
This is a great solution to what is sometimes a nagging problem. This heavy duty and flexible and adjustable plastic spacer can be put on the top or bottom radiator to prevent chafing in and area where it might come in contact the the engine or the radiator.
In this 28-minute instructional video Kent with show you how to do a compression test on your own Mercedes gas engine and explain how to interpret the results. It is very important you do this procedure BEFORE "throwing" parts at your engine trying to fix a performance problem.
2 large style clamps to be used on upper and lower radiator hoses. Use these to replace your thermostat or water pump without having to drain all your coolant out of the radiator. Works on medium size coolant hoses also.
This is a must-have if you attempting a caliper rebuild on one with stuck pistons. If you own one of our injector pressure testers here is a great add-on that will allow you to use the tester to remove stuck pistons from old brake calipers.
Diagnose door lock problems on 1977 to 1985 240D 300D 300CD 300TD 280E 280CE. For all 123 chassis cars with vacuum door locks from 1977 to 1985. Now you can finally fix those pesky vacuum door locks yourself!
With these old gas fuel injectors, sometimes you just have to "back flush" the insides to restore them to peak performance. There is no guarantee that back flush cleaning will restore every old gasoline mechanical fuel injector. Some are just plain worn out.
I have used a lot of different clamping tools over the years to prevent fluids from leaking out when removing coolant, fuel, or brake fluid hoses. Most work ok. Some are hard to use in tight places. Many do not stop every last drip from coming out of the hose.
In this 10 minute video class Kent shows you what you should initially look for when checking out an older Mercedes for sale. He routinely does a quick 3 to 5 minute walk around to determine if the car passes his priority three part test.
Those three areas on inspection are:
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.
APPLIES TO: The first general automatic climate control was introduced in 1977 in the U.S. market.
