This is a very common problem on the W123. The wood will just fall off someday. Worse when the car is left outside or in a hot climate.
Replacing a distributor cap is easy right. No problem?? If it were I would not get so many emails and why the engine won't run right after changing the cap and rotor. This is a short eight and a half minute video but the tips I share could save you some big headaches.
It is hard to find the right motor mount bolts for the 116 diesels. They have to be good hard steel and just the right length. We have provided locking washers to install with the bolts so they will not loosen up.
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 on-demand instructional video was filmed to go with Kent's new fuel tank sending unit service kit launched in June of 2020. This is not a complete video on the subject of fuel level sending units. For the complete video see related products below.
If your fuel gauge stops working or is not reading accurately, many times it can be repaired by removing it from the fuel tank, taking it apart and giving it a good internal cleaning of the contact points, float shaft, and wires.
We have been talking about this for years. It was Ryan who got a friend to make this for us. It is a very high-quality vinyl with a special stick adhesive that "breathes" and does not allow bubbles to get trapped during application.
This 11-minute instructional video will show you how to set up and use a digital tach to check the idle speed of your diesel engine and how to use the tools in Kent's kit to adjust the idle speed on 1977 to 1985 four and five-cylinder diesels ( not 190D ).

This 23-minute video will demonstrate how Kent repairs some small rust spots inside the fender wells of a W116 sedan. Disclaimer: This method of repair is not recommended for large rust holes under the car or for holes that have been caused by road salt.
When the motor won't move the window down you can not get to the bolts that hold the regulator to the glass. So then how can you get it out of the door! What a pain! In this xxx minute video Kent will show you what you need to do in order to get a "stuck" power window regulator out of a door.

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.
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.
In this video, Kent will show you how to safely and cleanly remove the fuel from the tank on your older Benz. You will need to drain the fuel anytime you replace the back end hoses, the tank filter screen, the fuel pump or the fuel filter.

Good used rocker arm assemblies as shown. This is the actual set you will receive.
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.
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.
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?
In this video, Kent will walk you through the steps needed to convert your older Brake Bleeder tank to one that can continue to bleed brake systems as well as pressure test radiators and cooling systems.
This was a good working unit before taken apart. All the internal parts are very usable. This will give you some repair spares for the future.
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.
If you are experiencing hard starting or unexplained loss of power, your engine's lift pump could be failing.
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.
Many uses for this quality hard steel tool including removing W123 and early W126 motor mount bolts.
Good used set of long mounting bolts as shown.
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.
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.
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

This video will cover the use of my custom plastic tool to safely remove the steel center section for the outside aluminum housing with rebuilding your older style SLS ( Self Leveling Suspension) hydraulic pump. No other instructions included here.
This price is for TWO nuts as shown. If you find you can not accurately adjust one of your older diesel engine valve clearances it usually means the threads on the lower adjusting nut are stripped. New ones are getting harder to find so we are offering good used as an alternative.
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.

This video will not only save the condition of your door panel, but it will save you a lot of time and frustration when you go to replace a door panel after doing maintenance inside your door. Those old plastic film liners always seem to be torn, ripped, and downright ugly.
We know that many of you own multiple Mercedes, including both gas and diesel models. If you own one of Kent’s fuel injector pressure testers you no doubt will want to test all your applicable mechanical fuel injectors in both types of older engines.
In this short video, Kent will give you an overview on setting up and using Version 3 of his bench mount CIS gasoline injector pressure tester.
This video is specifically for setting up and using Kent's newest version of his diesel fuel injector bench mount tester. It does not contain any information on the actual process of cleaning or rebuilding a fuel injector.
This is for number FOUR cylinder on the four and five-cylinder engines. No leaks. It may need to be straightened slightly for installation.
This is for number THREE cylinder on the four and five-cylinder engines. No leaks. It may need to be straightened slightly for installation.
