5-Cylinder OM617 Mercedessource Diesel Fuel Injector Nozzles w/ Heat Shields

German made for us by Wolfswerke-sachsen ( same company and same nozzle that was formerly branded as Monark). Machined for the 1986 and 1987 OM603 six-cylinder engine (see explanation below).

The Monark nozzles #120 are all gone, never to be remade. We do have a few hundred #128 nozzles still available. Kent and Kaia got together and started questioning why they would not work in the OM616 and OM617 engines. So in May of 2024 Kent decided to put them to the test.

1972 to 1987 Bosch Long Diesel Fuel Injector Critical Replacement Parts - Used

Other than the nozzle itself, these are the critical parts that wear out internally and can cause leaks and misfiring.

When “rebuilding” an old Bosch mechanical fuel injector, replacing the nozzle is usually enough get it working again at peak performance. But sometimes you will run into a fuel injector that just won't fire right nor product a correct fan spray pattern.
