heat-shield washer stuck!

Submitted by futbolpol on 27 June 2008 - 11:09am.

76 MB 240D [115]: I've removed the injectors and replaced the nozzles but I can't get the heat-shield washer out of 1 of the chambers. I've applied WD40, 'Liquid Wrench', diesel fuel, and biodiesel in an attempt to lubricate the chamber; I've tried prying the washer out with several instruments [which worked with 1 of the others that was also stuck], but I've only succeeded in mangling the washer itself, which remains stuck to the bottom.

Any ideas about cleaning agents to use or other techniques to try?

'76 300D will not reverse

Submitted by tnhand1022 on 19 June 2008 - 9:56am.

Automatic transmission. When I drop it into reverse the engine just revs as if it were in neutral. Park and drive are just fine, drove it 50 miles to home after the security guard pushed me out of the parking space. I've got two different mechanics saying I need a new transmission, but a guest staying at my inn says it might just need a reverse pin adjustment. Can anyone explain what this is to me? Or has anyone else out there had this problem? Thanks! Nicole

combu kit 3/8

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!

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.

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

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?

Price: $9.50
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 0,10 MM 6 Pc. Shim Washer Set for Diesel Injector Pressure Adjustment

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 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.

A/C compressor, '76 240D [115 chassis]

Submitted by futbolpol on 30 May 2008 - 10:10am.

One thing I've never tried to mess with myself is A/C. The mechanic who recently checked out my non-functional system said the compressor was ruined because a previous owner had converted it from R12 to R134. This didn't surprise me, based on what I've read on these forums, but what did was his categorical remark that replacing it with a used or rebuilt compressor wouldn't do. That struck me as unrealistic and perhaps also just mistaken. Can anyone with experience with used or rebuilt compressors confirm or deny whether these are a viable option on old Mercedes? Are there any details I should pay particular attention to when looking for one?
