(1) The Crankshaft Turning Tool is used on the front pulley.
(2) This Tool is used in the aperture for the electric starting motor.Note: Either Tooling (A) can be used. Use the Tooling that is most suitable.
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.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Put identification marks on all hoses, on all hose assemblies and on all tube assemblies for installation purposes. Plugging all hose assemblies and tube assemblies. Plugging all hose assemblies and tube assemblies helps to prevent fluid loss. Plugging helps to keep contaminants from entering the system.
Do not disconnect the air lines until the air pressure in the system is at zero. If hose is disconnected under pressure it can cause personal injury.
Release the pressure from the air system. Refer to the Original Equipment Manufactures (OEM) for the correct procedure.
Drain the coolant from the cooling system into a suitable container for storage or for disposal. Refer to Operation and Maintenance Manual, "Cooling System Coolant - Change" for the correct draining procedure.
If the engine is equipped with a hydraulic pump on the rear of the air compressor, remove the hydraulic pump. Refer to the OEM for the correct procedure.
Use Tooling (A) to rotate the crankshaft so that number one piston is at the top center position on the compression stroke. Refer to Systems Operation, Testing and Adjusting, "Fuel Injection Timing - Check" for the correct procedure.Note: The air compressor must be timed with the engine to minimize engine vibration.
