OPERATION&MAINTENANCE MANUAL
The gear transmission system consists of timing gear for crankshaft, timing gear for
cam shaft, timing gear for fuel injection pump and one inertia pump.
Fig9: timing gear meshing signs
Each timing gear is marked with timing gear except the gear for hydraulic pump.
Tooth position is the gear shall be in corresponding position, ( the gear marked with
number shall be in the middle of th4e gears adjacent numbers), to ensure mutual motion
relation of the parts, see figure 9 for detail. When installing gear for fuel injection pump
separately, the angel of advance for oil supply shall be met first, and no mark is
necessary, if marking is required, marks of the said three positions shall be aligned.
Special purpose tools are employed for assembling and disassembling for timing
gear of the crankshaft maybe installed by utilizing the two M8 screws on the wheel spoke
of the gear and serrated screws. Slippage positioning is employed for timing inertia gear
and the body. The timing gear of fuel injection pump is installed at the advance for oil
supply, which is fixed on the cam shaft of the fuel injection pump, only by unscrewing two
M8X35 bolt should we take out the gear for fuel injection pump.
7、fuel and governing system
Seventh. Fuel and speed adjustment system is the mail operational parts of the
diesel, which includes fuel conveying pimp, diesel filter, oil blowout pump, adjuster,
