Only two plugs are available. These are best for spares with an engine that already has fast pencil plugs installed. They fit 4-cylinder flat head diesel 636 engines built in the 1950s. These Monark ( made in Germany ) pencil-style fast-heat glow plugs can replace the loop-style plugs in the OM 636 diesel engine, whether it be in a Mercedes, a boat, a refrigeration unit, snow plows, or some farm equipment.
Product Details
NOTE: The instructions included with this kit will explain the installation process in an older Mercedes. If you are operating an OM 636 engine that is not in a Mercedes diesel passenger, you may need to install a resistor that will lower the voltage to 9.5 volts under load. In any case tests of the electrical system are required to ensure the delivery voltage is in the proper range. In most Mercedes installations, the dash glow indicator (resistor) is enough to keep the voltage in check. If it is not working properly then an alternative ballast resistor may be required to keep the glow plugs from burning out prematurely. No warranty against burn-out!
OM 636 Diesel Engine:

- 4 German made Monark Glow Plugs specifically for the OM 636
- 3 Heavy wires to connect the glow plugs in parallel along with nuts
- Installation instructions
Comparing the old with the new style glow plug:
DISCLAIMER: NO WARRANTY AGAINST BURNOUT IF OPERATED WITHOUT A PROPER RESISTANCE IN THE WIRING THAT REDUCES THE VOLTAGE TO A MAXIMUM OF 9.5 VOLTS UNDER LOAD
