For all 615 616 617 601 602 603 engines 1961 to 1995 - FREE SHIM PICK TOOL IS INCLUDED. Both myself and our customers are so impressed with the quality and performance of Monark Nozzles I wish I could convince everyone to install them in their Mercedes diesel. To tune them properly you will need a bench pressure tester and these adjustment shims (also made in Germany by Monark). Be sure to click on the links below to see what else you will need to rebuild and tune your fuel injectors. I work long and hard to make sure you have the very best parts, tools and supplies available to rebuild injectors yourself AND make sure it is done right! Kent Bergsma
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. This includes models 190D 200D 220D 240D 300D 300CD 300TD 300SD 300SDL and 350SDL. 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.
Kent has solved this problem with the release of his DIY Variable Shim Washer Kit. Geared specifically for the home mechanic who only occasionally needs to adjust injector pressures. Rather than having 70 to 100 different shims on hand you now only need 24 shims total to meet the variable requirements of adjusting one set of 4 to 6 injectors. Of course you will have extra left over. Keep in mind that in extreme cases of worn injectors there is a possibility this shim kit may not have all you need. We tried to balance the price and the assortment to meet most owners needs.
The key is using more than one shim to meet the total thickness requirement. Buy using a thicker shim along with 1 to 2 thin shims you will be able to make any thickness you need. This kit contains two each of EIGHT different thick shims that are bunched 0,20 to 0,30 mm apart from each other. Along with these 16 thick shims there are 8 of the thin 0.10 shim washers. 24 shim washers TOTAL are included. This will allow you to combine thick and thin shims to get just the thickness you need. ALL SHIMS have the same outside diameter which is 11.5 mm, so they can be used on other diesel injectors besides Mercedes that use the old mechanical fuel injectors for indirect injection. Kent even throws in his factory pick tool to get the shims out of the injector housing at no extra charge.
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 one of the thicker shims in this kit and adding 1 or 2 thin ones to build the thickness required. You have many variable options with this new kit. Comes in a nice plastic divider case, gloves, and a little treat to put a smile on your face.
To measure the thickness accurately you will need a good metric digital caliper. If you do not have one of these in your tool kit we offer one on this website for a very attractive price. Look below to view this caliper. We also carry a full tool kit for cleaning, tuning and overhauling your fuel injectors.
IMPORTANT NOTE: Using these hardened shims made in Germany is the VERY best way to accurately adjust your diesel injectors release pressures and to be assured that the adjustment will hold up over time!
Instructions not included. Instructions for using these shims to adjust release pressures is included in Kent's injector cleaning, overhaul and testing manual available separately. BONUS: This same shim kit is included in our delux diesel fuel injector overhaul kits. See related products below:
