In order for our electronic ignition to work properly and to work at peak performance, you must have a good ignition coil with no internal resistance and a good ballast resistor with a resistance of between 1.2 and 1.9 ohms.

Do not let anyone convince you to install some super platinum, iridium or kryptonite spark plug in your old Benz. They are just not capable of handling the richer fuel mixtures associated with these older engines.

When changing the front crank seal on your older 6 cylinder Mercedes you may or may not need to replace the sealing race that goes on over the front of the crankshaft.

When doing a compression test you must properly seal the inner surface of the pre-chamber with the fuel injector hole adapter. Copper washers work the best for this to ensure a 100 percent seal. Do not use the engine's heat shield washers.

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.

Excellent used emergency stop lever as shown with good rod bushing and C-clip included.

FULL set of 12 new spark plugs for your V6.

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.

If your V8 is running hot or temp gauge is moving you may have a bad sending unit. Located at the front of the engine. Easy replace. Drain one gallon of coolant out of the radiator before removing it. 

This is a common failure item that can leave you stranded. Better to replace it with an improved new part BEFORE your engine quits cold. You can do it yourself with the right tools and instructions. Watch Kent's YouTube video for an introduction to the problem and why this kit is needed:

Super clean. Removed from a low mileage 4.5. Look at how clean it is inside and there are no loose timing chain marks. Just clean with solvent, blow off and install. You won’t find them this nice very often.

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.

Do not let anyone convince you to install some super platinum, iridium or kryptonite spark plug in your later model R107 SL V8. They are just not capable of handling the richer fuel mixtures associated with these older engines.

Good used rocker arm assemblies as shown. They come with stretch bolts but washers are missing.

Check the picture closely. This is exactly what you will receive.

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?
