If you are going to buy or have just purchased an older 5 cylinder Mercedes Diesel (1975 to 1985) the first thing you need to do is a good physical exam of the engine. It is even better to do this BEFORE you purchase the car to prevent surprises and pain in your wallet. Check out what happened to us recently in our PROJECT DRIVEWAY restoration by CLICKING HERE!

I have gone through a lot of pain dealing with leaks in SVO conversion systems. Vegetable oil has an amazing wicking ability and will leak out of the slightest thread flaw. This is particularly true if you use iron pipe fittings or fittings of dissimilar metals.

This is the tool I love to use when troubleshooting engine operating temperature problems. You can stand back and aim the beam right on a spot on the radiator or engine to get an exact temperature reading. This can indicate whether or not your radiator is plugged and confirm if your temperature gauge is accurate or not.

If you are running SVO it can give you accurate readings of the temperature of your oil - both during filtering and coming out of your boost heater.

Features:

High Quality (made in USA) brass two way fuel rated valve with brass fittings for 3/8 inch fuel hose. Can be used to select between two fuel tanks or as a control valve for your loop or return fuel with running on SVO. Comes with two straight non-barbed hose fittings and one 90 degree fitting. This will allow max flexibility in how you route your fuel hoses. NO instructions included.

This will allow max flexibility in how you route your fuel hoses. NO instructions included.

If you have read very many of my manuals and instructions you already know how much I detest Silicone Gasket Sealant. I know there are places for silicone (ie bath tub caulking, etc), but it should not be used on internal combustion engines!

Applies to all Mercedes, PON FIN Pre 1960, 190SL, 110, 111, 112, 113, 114, 115, 108, 109, 107, 116, 123, 126, 201, and 124 chassis. Here is a kit you will love to have around the shop.

Kent has packaged together four of his most popular signature series products that will allow you to service, overhaul and tune your diesel fuel injectors yourself. All together these are key to helping you understand how your fuel injectors work, how to inspect and clean them, how to install new performance Monark injector nozzles, and how to balance tune them for maximum power and fuel effeciency.

These include the following items: Click on each one to read more.

Fuel Injector Pressure Bench Tester 

Diesel Injector Cleaning and Testing Procedures 

Diesel Injector Cleaning Brass Tool Kit 

These thin shim washers can be added to an existing injector shim to meet the thickness required to increase release pressure. Buy using a thicker shim along with 1 to 3 thin shims you will be able to make a number of different thicknesses within the 0,20 mm range. This kit contains six each of thin 0,20 mm washers.

These thin shim washers can be added to an existing injector shim to meet the thickness required to increase release pressure. Buy using a thicker shim along with 1 to 3 thin shims you will be able to make a number of different thicknesses within the 0,10 mm range. This kit contains six each of super thin 0,10 mm washers

If you are adjusting your injectors and your pressure reading is low you may only have to add one or two of the thin washers to bring the pressure up to spec. If your pressure reading is too high you will need to go down in thickness by choosing a think shim you have available and adding 1 or 2 thin (or any multiple you like) ones to build the thickness required. We also supply thin washer sets in 0,05 and 0,20 mm sizes.

One of the more challenging aspects of adjusting the release pressures on your diesel fuel injectors is finding the exact thickness shim washer you need to make the proper spring pressure adjustment. If you try to do it with just one shim per injector you end up needing a large assortment of all sizes of shims ranging from 0,80 mm to 1,95 mm. And knowing Murphy’s law all too well, you will end up needing the shim size that you do not have.

You are looking at the worlds first production diesel mechanical fuel injector bench tester available in the U.S. for under $200. These are built in Mercedessources own shop to control quality and production demands. This bench mount tester will allow you to economically test the spray pattern and fine tune (balance) your fuel injectors at home. With the injector fitting included it will work on all Mercedes diesels from the early 1960's up to 1993. It will also work on any mechanical Bosch type fuel injector with adjustable pressure release function - altough you may have to come up with your own adapter to attach the injector to the tester. (manufactured up to the mid 1990s). Assembled with special FLUTTER GUARD pressure gauge to stabilize needle bounce.

This is a 3 piece scribe and pick tool set - great for marking aluminum and steel.

Heat shrink tubing is very handing to have if you are doing any wire connections or splicing. This tubing can go over the splice or solder joint and when heat is applied from a heat gun it will shrink right down tight to the joint and protect it from shorts and corrosion.

This circuit tester has a long 7 inch point to get into hard to reach places. Accordion cord extends up to 12 feet! Wow!

This is a set of metric nut drivers. It come in 7 different handy sizes and is even color coded. Sizes include 5, 6, 7, 8, 9, 10, and 11mm.

If you plan to change coolant hoses this is a must have labor saving tool. This is one cleverly designed tool. Could not have done it better myself. I actually use to make a couple different types before I found this one. If you have ever tried to remove a radiator hose corroded to an aluminum housing you know what I am talking about and you will love this tool. Great when changing radiator hoses, especially the short hose. 8 inches in length.

It will get those stuck radiator hoses loose and off in seconds...

I like this - permanent - threadlocker because it is super strong but can still be removed with a heavy handed breaker bar. This is a very large bottle for the price and is a must have for Mercedes diesel owners. I use it anytime I am doing major repair work on an engine or transmission. Great for front crank bolt, cam bolt, torque converter bolts, injection pump mounting nuts, front engine accessories, brake caliper bolts, front suspension, etc. Anything that you can just not afford to come loose.

This removable thread locker is probably the best that I have used. It has the best sealing cap and cures rapidly and reliably when confined between metal parts. Use it to lock threaded fasteners, nuts, bolts and screws from loosening. Extremely important in critical engine and suspension parts. This is the removable type (meaning that it can be easily removed with hand tools). Comes in small .20 Fl oz. bottle great for most small jobs.

Excellent for all work around diesel engines to prevent vibration failure and breakdowns. If you need the red more permanent type CLICK HERE.

This permanent thread locker is probably the best that I have used. It has the best sealing cap and dries hard in 20 to 60 minutes. Use it to securely lock threaded fasteners, nuts, bolts and screws from loosening. Extremely important in critical engine and suspension parts. This is the permanent type (meaning that it is possible to remove only when applying heat to 450 degress F - with propane torch) or a very heavy breaker bar. I like to use this one on brake caliper bolts as it is such a critical bolt.

Excellent when retaining bearings and bearing races, freeze plugs, rocker arm and main bearing studs, etc. Can fill gaps up to .007 and assures positive controlled locking.

Fits chassis 116 123 126 and 201 Diesels with PENCIL glow plugs, from 1978 to 1989. This little strip fuse is located in the Glow Plug Relay and can sometimes be the cause of your glow plug problems. Even if it appears to be good, we recommend that you physically remove it and inspect it for cracks or breaks before you replace the Relay! Sold in a 2 pack.

 

If you work around your Mercedes much this is a great tool to have. The quality is exceptional for the price. It will reset to measure in both inches and millimeters. For a limited time I will even include a spare button battery at no extra cost.

If you are going to test and tune your diesel fuel injectors this is a must have tool! It is the best way to determine the current thickness of the pressure adjusting shim washer in each injector and to help choose the proper replacement. We are committed to helping you service and overhaul this critical maintenance component.

As I have said elsewhere on this site, fuel injectors may be the most neglected maintenance item on the older Mercedes diesel engines. Just because they are working does not mean they are working well. And now with the cost of diesel fuel creeping up to $5.00 per gallon this is even more important than ever! You can work on your injectors yourself. It is not difficult, but you are going to need the right tools. I have put together this quality but inexpensive tool set for those who want to tune-up or overhaul their injectors on their own. If you are running SVO in your diesel you MUST take care of your injectors or your diesel will not take care of you. This tool set includes the following:

We have looked far and wide for the right size WVO HD pump pickup filter and have finally found it. Our criteria was it had to be all metal, had to be not too small or too big, had to take fitting for 3/4 inch hose, had to have a bottom surface to mount a stand pipe, and had to be easily cleanable. Now comes with three cleaning brushes, a plastic stand pipe that you can glue on if needed and pictorial instructions loaded with tips.

If you are installing a dual tank conversion in your Mercedes you are going to need a way to allow the hoses to enter the trunk somewhere. The best way to do this is to use a hole saw to cut one or two round holes in the spare tire will in bring in the coolant hoses and/or fuel hoses. The hoses can be protected from chaffing with tape and then sealed with Silicone to prevent water and dirt from entering your trunk. Yes, I know these hole saws are not meant for metal - and that is why you need this cheap set. No need to dull your expensive hole saws. Once or twice on metal and the saws are done. But then you wont be using all the sizes in this kit so you will end up with extras for future wood projects around the house.
