4 CYLINDER 220D 240D 190D 2.2 Monark Diesel Fuel Injector Nozzles with Heat Shields

Fits the following: All 4 cylinder diesel engines from 1968 to 1985, including 201 Chassis 190D 2.2. This is the critical inside wear part of the injector that delivers the fuel spray into the cylinder. Replace for better fuel economy, more power, easier starts, and less exhaust smoke.

We want to help you get your diesel performing better. If your injector tips are worn out here are my recommended replacements. These injector tips are made by Monark in Germany and they are designed with a finer mist pattern than that produced by the Bosch tips. My experience has shown that these tips work better (fuel burn) especially on higher mileage diesels with less than perfect compression numbers. On my own diesels I have also noticed less injector nailing (pinging noise) with these tips installed. Always replace the crushable heat shield washers when replacing your fuel injectors.

Fuel injector easily disassembled for nozzle replacement

Partial instructions are included - covers installing new nozzles in injection holders - but does not cover removal from engine or injector pressure balance testing. If you want complete detailed instructions for all things related to removing injectors, cleaning used injectors, checking spray pattern and balance pressure adjustment, then I would strongly recommend you purchase my complete manual Diesel Injector Cleaning and Testing Procedures.

Ideally you should pressure test and set the correct release pressure when installing new tips. If there is a Bosch repair facility near by you can have them do this testing/adjusting for you. You can install these tips without checking adjustment and in many cases they will fall into an acceptable pressure/spray pattern range. This might be preferable to badly worn out fuel injectors - but best to test pressures and balance injectors if you can.

New tip design produces spray pattern with better atomization (fine mist)

IMPORTANT NOTE: If you are running SVO WVO or B100 these have the highly touted DN OSD 261 specification. These have a newly designed tip for modern fuels. Bosch tips have some horizontal and vertical bores in the tip. These easily plug up with running SVO or B100. With these injectors you do not have that problem and they produce a finer spray pattern for better combustion. Many, including myself, have reported great results when running heavier viscosity fuel. I consider these a must have if you are running waste vegetable oil for fuel.

ADDITIONAL ITEMS NEEDED: Anytime you remove and replace your injectors you must replace the heat shield washers under the tips. FOUR HEAT SHIELDS ARE INCLUDED WITH THESE NOZZLES! You will also more than likely need to replace the rubber fuel return hoses connected to the injectors. Trying to reuse the old hardened hoses almost always result in leaks. We sell the injector return line in the factory braided style,, as well as in viton for biodiesel.

I recommend you have a torque wrench handy when rebuilding your injectors. If not we offer one at a great price. CLICK HERE to order.Use a torque wrench when cleaning or rebuilding injectors
