Why Does My Diesel Engine Run So Badly? - JULY PROMO

Item: SRCLET-WDRB
Price: $9.95

Run_Badly_S.jpg

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?

View Product
Thin shim 0,20 x 6

These thin shim washers can be added to an existing injector shim to meet the thickness required to increase release pressure.

thin shim 0,10 x 6

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.

Variable 30 Pc. DIY Shim Washer Kit for Diesel Injector Pressure Adjustment - NEW!

variable shim kit

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.


monovalve failure? 87 190dt constantly blowing hot air

Submitted by backlipper on 14 May 2008 - 11:25am.

I have an 87 190dt that is constantly blowing hot air regardless of climate control setting- on or off. Any suggestions? I have seen threads on other sites that pointed to the monovalve. Kent, if it is the monovalve have you written a repair book for the 201 chassis yet?

1989 190e Drivers Seat and the Left Rear power window do not work

Submitted by rolands.benz on 11 May 2008 - 4:35am.

May 11, 2008

Dear Benz Guru and wise one,

I just purchased a 1989 190e with 152,000 miles.

Here are issues I found out.

1) The power drivers seat do not work. It will only slide forward but not backward, and the upper recline does not move forward.

2) The Left Rear power window do not work at all.

3) The Drivers door does not Lock/Unlock at all.

4) The headlights flash and a clicking sound under the front passenger dash side occurs when unlocking and locking the car with the passenger door lock.

5) The hood and car top clear coat has peeled off. I was thinking of a whole car paint job with Earl Scheib or MAACO auto paint. The original paint color is a light blue metallic. I was thinking of having the car repainted to a light grey color. Your thoughts please.
