NOVEMBER SPECIAL: BUY ONE AND GET THE SECOND FOR HALF PRICE! (If you don't have two cars you should carry a spare in your trunk - failure of this part has proven to be the number one reason your Benz will quit and won't crank over to restart).

This tune up kit fits the 6 cylinder twin cam engine in the 1990 to 1993 300SL, the 1990 to 1992 300CE coupe, and the 1992 to 1993 300SE 140 Sedan. Why this tune up kit and why do I call it run insurance? Let me explain:

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!

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:

Front suspension overhaul is almost always left until one has fixed everything else on the car. We know that most owners can live with some looseness in the suspension, especially when you consider the age of the 116 chassis. But if you want to restore that great Mercedes factory feel and ride (that we all love!) there is no short cut but to replace all the rubber and wear parts in the lower section of your front suspension. NOTE: This kit does not include the upper control arms as we have found many have already replaced those as they often fail first. If yours have not been replaced and you want the full deal, then we recommend you also order those separately. CLICK HERE.

This seal and gasket kit will solve your problems with any external or internal (into the engine) leaks at the hydraulic pump (location at the front of the cylinder head). If your hydraulic fluid is disappearing from the tank and you can't see any leaks in your rear suspension - then it is possible the shaft seal of your pump is bad and fluid is leaking into your engine oil (and yes, this is not good!). This same pump is used on all Mercedes self-leveling suspension systems from the late 1970's up through 1991. Your pump will need to be removed from your engine in order to install new seals and gaskets. You should have correct fluid (Mercedes type) and a new fluid filter on hand before you begin.

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!

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.

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.

With diesel fuel approaching $5.00 per gallon you cant tell me you are not interested in this subject. I know you may have lots of questions. To begin you must decide if you really want to do this!

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:

If you run or plan to run B20 to B100 biodiesel or SVO / SVO blend (straight vegetable oil) I highly recommend you do not count on just your factory filter to provide proper filtration. Our Stanadyne FM 100 filter has a much larger capacity and better water separation capability than the factory filter. This will give you better filter life and better performance over a longer period of time. This filter is much easier to change on the road and less messy that the factory filter. It fact it is the easiest filter to change of any of the competition aftermarket filters by far. No tools are required - only the twist of your wrist! It has proven to outperform any Racor Fitler on the market for less money and less hassle!

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.

Have you been trying to find the right hose kit to upgrade your current WVO conversion. I know you want something that can handle biodiesel when you run it and you want something that can hold up to your boost heater. You also want to get rid of your ridiculous barbed fitting and cheap hose clamps that keep cutting into your fuel hoses!

Now you can order this kit and solve all those nagging problems once and for all! This kit contains:

This is the super fuel hose we have been waiting for! Finally a hose that meats all the needs for running, gasoline, ethonol, diesel, biodiesel, and heated SVO in less than ideal environments. There is nothing else like it on the market today.

Now you can buy it in any length you want! Order here by the foot. This is the super fuel hose we have been waiting for! Finally a hose that meats all the needs for running, gasoline, ethonol, diesel, biodiesel, and heated SVO in less than ideal environments. There is nothing else like it on the market today.

Hard to find original braided hydraulic fuel hose for your 123 wagon. I find this hose to be rotten and needing replacement on almost all 123 wagons I see come into the shop. Enough length included for one replacement. Comes with two new high quality (non-cutting) German hose clamps.
