The following charts show the latest usage of fuel nozzles and fuel injection pumps in 3056 Machine Engines.

Static Timing

The engine check angle must be used with the 9U-6188 Timing Fixture Group, and with the engine set with the number 1 piston at top dead center (TDC) on the compression stroke. The pump is checked with the pump set at the start of injection for the number 1 cylinder. (See your Service Manual).

The fuel pump code letters are included on the setting code stamped on the data plate of the fuel injection pump. Some fuel pumps may have the setting code stamped on a modification plate which is fastened to the flange of the pump. If a modification plate is installed, use the code letters stamped on this plate. A typical setting code is 2643C601BM/4/2860; In this example, the code letters are "BM" .
