116, Diesel Engine

You have asked for it and we have delivered again. Now that all those old power steering pumps are leaking out the front seal we have come up with a kit that will allow you to replace the front seal of your pump at home without any special tools. This kit will work on all power steering pumps on 4 and 5 cylinder diesel engines from 1977 to 1985 (excluding the 190D 2.2).

Kit contains the following:

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:

Set of FIVE Rebuilt Bosch Fuel Injector Housings with high performance Monark Nozzles installed. Each injector has been bench tested and pressure balanced in our shop. All injectors are set to release pressures between 1900 and 1950 psi. This set of injectors will work in all 300SD 1978 to 1985 and all 123 300D 300CD and 300TD with turbo diesel engines.

Injectors will be shipped with new heat shield washers as shown. No instructions included.

NEW LOCTITE PRODUCT - AUGUST PROMO! 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!

These rubber end plugs can be used to cap off your vacuum on the end of a line or on certain components. FOR USE ON VACUUM SYSTEM ONLY. These are NOT to be used on fuel injectors.

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 were swollen and would just not stay connected? This is a L shaped fitting that fits 115, 116, 123, and 126 chassis.

This part allows you to properly adjust the belt tension on all 617 5 cylinder turbo diesel engines. It is common for the plastic block to break apart. When that happens you adjusting bolt will just spin without any affect on the belt tension. We only have a few of these available used.

This size freeze plug fits almost all gas and diesel engines from the early 70s up into the 90s. This includes all 61x and 60x diesel engines, the 103 gas engine in the 190E, 300SE and 300E. It also fits many V8 engines but you should measure your current plug to be sure. This part measures 34 mm in diameter.

We are seeing more freeze plugs rust out from the inside as these engines age. First sign will be a little rust ring around the outside edge of the plug, next sign will be slight coolant loss, and last sign may be catasropic engine over heat. Check your freeze plugs for any sign of deterioration NOW.

Complete R134a retrofit kit as shown to convert your A/C system.  Keep in mind this may not repair all problems with your current A/C system. This kit is designed to go into a good working system. There maybe other parts you will want to purchase such as receiver dryer, etc while doing this conversion. Consult with your local A/C specialist if you are unfamiliar with air conditoning systems.

PLEASE NOTE: We are supplying this inexpensive kit as a convenience to our customers. It will not come with detailed instructions nor do we offer support on how to convert your current system. That will be between you and your local A/C specialist.  

New German high quality Factory type engine oil filter. This is for one (1) filter in the box. Includes oil filter housing cap o-ring and oil pan bolt sealing washer. Does not include instructions. Fits all 123, 116 and 126 4 and 5 cylinder diesels to 1985.

This is one cool pre or final protection fuel filter. I have been looking for something like this for a long time. Not only is it all metal, just the right size, has a 60 micron large cleanable screen, but it can be taken apart by hand... and that is certainly a big plus when you are out on the road faced with a plugged-up filter!

PLEASE NOTE: THIS IS NOT A PRODUCT, JUST INFORMATION WE WILL BE PROVIDING ON THE WEBSITE. STILL UNDER CONSTRUCTION! This question could well be the number one request we receive from new customers. The question seems to be popping up frequently now as many people are buying these old diesels for the first time hoping to convert them to run on alternative fuel. It is a great idea and can be a rewarding endevour IF you find the right car to begin with and are willing and able to repair it yourself.

Running badly means poor performance. It happens sooner or later to EVERY diesel owner. The word "performance" is often used to describe how well a diesel engine runs once started. The principles discussed will cover all Mercedes diesels from the mid 1950s to the mid 1990s. Throughout this manual I will use this word to discuss a number of common problems. How performance is rated can mean different things to different people. In the following pages I will relate diesel performance to the following four criteria:

• How much power does it produce?
• What kind of fuel economy does it deliver?
• How smooth does the engine run?
• How much does the engine smoke?

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.

The injector heat shield washers on a diesel engine must be replaced anytime you remove your fuel injectors. These fit 240D, 300D, 300TD, 300CD, 300SD 1974 to 1985. CLICK HERE to view our nozzle kits.

Brand new Mercedes rear most (#5) metal fuel injector hard line. Fits all 5 cylinder diesels turbo and non turbo from 1977 to 1985

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 alumium 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.
