If you are going to work on your diesel fuel injectors, you are going to need a torque wrench. If you are going to tighten your alloy wheel lug bolts properly, you should use a torque wrench. In fact, if you do your own work, you should have a 1/2-inch clicker torque wrench in your toolbox.
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.
This is another small "frustration" for W123 diesel owners. The fuse box cover is mounted flat to the firewall behind and to the left of the brake booster. You can not just pull it straight out nor can you just push it straight back on.
We also carry this in other sizes. See related products below.
This is a very handy smaller torque wrench to have in your toolbox. Perfect for spark plugs. It will do fuel injectors but is not quite big enough to torque wheel lug bolts. Range is 5 to 80-foot pounds. The case will be black rather than red.
Tightens and Removes Collar Nuts on 220D 240D 300D 300CD 300TD 300SD 300SDL 190D 2.2 1969 to 1987. Works on most Mercedes diesel engines up through 1987 only.
Any time you are removing and replacing your fuel injectors you will need to change the return hose and the heat shield crush washers. If you don’t, you will have leaking hoses and possible compression leaks at the injector nozzles.
Works on 110, 115, 116, 123, 201, 126 and 124 diesel engines 200D 220D 240D 300D 300CD 300TD 300SD 190D 300SDL. We have found that over half of the deep sockets we test will not go over some of the longer injectors.
I figured out why the spark plugs in these V6 engines don't seem to ever get changed.
With this deluxe kit, you can reduce frustration and save big when doing it yourself. Watch the videos below to learn more!
5/25/22 update: The precision nozzles included are now made for us by Wolfswerke-sachsen ( same company and same nozzle that was formerly branded as Monark). Yes!
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.
5/25/22 update: The precision nozzles are now made for us by Wolfswerke-sachsen ( same company and same nozzle that was formerly branded as Monark). Yes!
New head gasket set. Fits all 5 cylinder TURBO diesel engines only from 1978 to 1985 including 300D, 300CD, 300TD and 300SD. Comes complete with all gaskets only as shown in the picture. Valve stem seals, chain tensioner gasket, thermostat housing gasket, and valve cover gasket are NOT included.
Here is another diesel item I strongly believe should be replaced as a preventative measure. Water pumps do not last forever and when they go, it is usually when you are on a trip - right? I feel they should be changed every 100,000 miles.
Fits 115 116 123 and 126 chassis diesel engines, non turbo and turbo, to 1985. This includes the 220D, 240D, 300D 300TD wagon and 300D/300SD turbo engines. Most thermostats only last a few years and should be changed for optimal diesel performance.
For all MBZ diesel engines 1950 to 1999. Designed by Kent Bergsma. These are built at Mercedessource to control quality and production demands. Each one is tested here in our shop before shipping.
Why is this so important? It is primarily due to the age of these cars now and the fact that lurking problems can be hidden from visual inspection. There is not ONE diesel that Kent has looked at in the last five years that does not need this service! Even ones with under 150,000 original miles.
8/2022 Update: We have modifed a new wrench for this kit so it may not look the same as that shown in previous YouTube videos, but it will do the same or even better job! We do sell the water pumps individually, but we decided to offer this complete kit to make a diesel pump installation go easie
Includes Kent's four detailed videos on every aspect of this job! This is our combination kit for DIY installation of a new front crank seal in an OM 616 four-cylinder and OM617 five-cylinder NON-turbo diesel engine. The price if purchased individually is $174.00.

FITS THE FOLLOWING: All Mercedes Diesel engines from 1968 to 1999. This includes 115, 123, 116, 126, 201, 124 and early 140 chassis. Also 210 Chassis E300D to 1999, 220D 240D 300D 300TD 300CD 190D 300SD and 300SDL.
When was the last time you knocked one of your vacuum lines off around the oil filter housing, only to discover when you tried to reattached it that the fittings or hose were swollen and would just not stay connected?
These steel cupped heat shields go under the rubber mounts to help deflect heat and grease away. In most cases (unless your engine is severely shaking) they will prolong the life of the rubber mounts.
Excellent used flywheel. Has good gear teeth for starter motor.
Almost all Mercedes gas and diesel engines from the late 50's up to the early '90s used pressed in steel pins to hold the timing chain guide rails in position (inside the engine block).
Have you noticed your Mercedes diesel sedan is recently shaking more at idle. Maybe you are noticing new vibrations that were not there before. You may have also noticed the engine makes some clunking noise when you shut it off. When was the last time your rubber motor mounts were changed.
Fits 115 and 123 chassis 220D and 240D to 1983. Check yours for staining around the gasket. Also check nuts for tightness. These symptoms may indicate a leak. This is an important maintenance item! I have seen bad leaks as well as completely loose intake and exhaust manifolds.
Fits all Diesels from 1965 to 1985
If your diesel engine is starting to shut off very slowly or maybe not at all and you know your vacuum system is ok, it may be time to replace the vacuum fuel shutoff valve located at the rear of the injection pump.
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.
Lubro Moly Diesel hi test fuel additive that does far more than just add lubrication to the fuel. Formulated for the new low sulfur diesel fuel. Contains an additive against injection pump and injector wear.
New turbo charger turbine shaft and exhaust turbine wheel as shown. This part has been highly balanced and is ready for installation. Make certain your compressor wheel is not bent or damaged as that could throw it out of balance. Comes with new shaft nut.
Includes Kent's four detailed videos on every aspect of this job! This is now becoming one of the most common oil leaks in 1968 to 1985 diesel engines. Let's face it.
Set of 10 fuel injector sealing washers. Also know as heat shield crush washers. Fit 1984 to 1999 Mercedes aluminum head 60x. diesel engines 4, 5, and 6 cylinder (190D, 300D, 300TD 300D 2.5 300SDL 350SD S350 and E300D).
COHLINE BRAND
New heavy duty water pump complete with gasket that fits all 190D 2.5, 124 chassis 300D, 300TD and 300D 2.5, 126 chassis 300SDL and 350SD and SDL, and 140 chassis 300SD and S350D. No instructions at this time.
Fits all W116, W123, and W126 Turbo Diesel 5 cylinder 300D and 300SD engines from 1981 -1985 as well as M110 6 cylinder engines from 1977 to 1985. This is a brand new Lower engine Oil Pan and Gasket. Remove and inspect your oil pan if it has been badly dented.
Two replacement levers as shown. NOTE: Often the valves are still ok but the lever is worn off.
This is now becoming one of the most common oil leaks in 1968 to 1985 diesel engines. Let's face it. These engines are getting older and the rubber seal is wearing and becoming more brittle with time.
While working on the fuel injectors of a 240D this week, Kent finally decided he had had enough. After 20 years of fighting those fuel injector return hoses he decided he just had to come up with a tool to make the job easier. 2 hours later the tool was designed and the prototype made.
This is the best way to determine if the expensive injection pump is going to work for old 4 AND 5-cylinder diesel engines that have not run in years. Watch the video below to understand what this kit can do.
Kent's procedure uses the factory recommended "drip tube method" but with a "twist." He has devised a way to get accurate and consistant IP timing results while trying to get the drip tube to drip at one drip per second exactly when it should!
PLEASE NOTE: This is a wiring kit ONLY. You will need special FAST glow plugs and glow plug wires to complete a successful installation. This kit will not work with your orginal lopped-end series glow plugs.
In a perfect world your diesel would not leak a drop of fluid. Unfortunately, with the age of your vehicle, it may not be economically possible to eliminate every leak. Sometimes you may just have to live with some leaks.
Can be installed on the following models: Please read carefully. All Turbo 116 and 126 300SD 1978 to 1985. All 123 turbo and non turbo 240D 300D 300CD 300TD 1980 to 1985. 1984 to 1989 201 190D. 1986 to 1991 126 300SDL 350SD and 350SDL. 1986 to 1993 124 300D and 300TD.
Version 4 update 2/22: New color and style but still does the same job. This is one of the key tools you will need to remove stubborn pre chambers from the cylinder head of your old diesel engine.
This came off a turbo engine but many don't know it makes your non-turn engine really spin! Excellent used working starter motor. This starter motor can also be fitted to the W123 240D and 300D non-turbo engines to make the engine turn faster for quicker starts in cold weather.
Damage to these is becomming more common as they engines age. If your fuel injectors are not firing fuel properly the ends of the prechambers cac burn right off causing all sorts of "weird" engine performance problems.
