CYLINDER GP-HYDRAULIC 4998869 - Caterpillar

Removal Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g01342429
Typical example
Disconnect the breather hose from the separator for the crankcase breather. Refer to Disassembly and Assembly, "Crankcase Breather - Remove".
If the engine is equipped with a cover over the fuel system this will need to be removed.
Remove bolts (1) from valve mechanism cover (2).
Remove valve mechanism cover (2) from the valve mechanism cover base.
Remove joint (3) from valve mechanism cover (2).
If necessary, remove the separator for the crankcase breather from the valve mechanism cover base. Refer to Disassembly and Assembly, "Crankcase Breather - Remove". Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Thoroughly clean all mating surfaces of the valve mechanism cover. Clean the mating surfaces of the valve mechanism cover base.
If necessary, install the separator for the crankcase breather to valve mechanism cover (2). Refer to Disassembly and Assembly, "Crankcase Breather - Install".
Illustration 2 g01342429
Typical example
Install a new joint (3) to valve mechanism cover (2). Note: Ensure that the joint is fully seated into the groove of the valve mechanism cover.
Illustration 3 g01342430
Ensure that harness assemblies (5) are not in contact with the rocker arms of the valve mechanism cover base. Position valve mechanism cover (2) onto valve mechanism cover base (4). Ensure that harness assemblies (5) are not trapped during the assembly procedure. Install bolts (1).
