21. NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened component life.
NOTICE
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting and repair
of the product. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component
containing fluids.
Dispose of all fluids according to local regulations and mandates.
Note: Either Tooling (A) can be used. Use the Tooling that is most suitable. Care must be taken in
order to ensure that the fuel injection pump timing is not lost during the removal of the front gear
group. Carefully follow the procedure in order to remove the gear group.
1. If the air compressor is equipped with a hydraulic pump, remove the hydraulic pump. Refer
to Original Equipment Manufactures (OEM) for the correct procedure.
2. If the engine is equipped, with an air compressor remove the air compressor. Refer to
Disassembly and Assembly, "Air Compressor - Remove" for the correct procedure.
3. If the engine is equipped with only a right-hand side hydraulic pump, remove the hydraulic
pump. Refer to the OEM for the correct procedure.
4. Use Tooling (A) in order to rotate the crankshaft so that number one piston is at top dead
center on the compression stroke. Refer to System Operation, Testing and Adjusting,
"Finding Top Center Position for No.1 Piston" for the correct procedure.
Note: Do not use excessive force to install Tooling (D). Do not use Tooling (D) to hold the
