ELECTRICAL AR 3271687 - Caterpillar

Removal Procedure
Start By:
Disconnect the crankcase breather or remove the crankcase breather. Refer to Disassembly and Assembly, "Crankcase Breather - Remove".
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
If the valve mechanism cover is equipped with a heat shield, remove the heat shield.
Illustration 1 g01353908
Typical example
Remove bolts (1) and (3) from valve mechanism cover (2).
Remove valve mechanism cover (2) from the valve mechanism cover base.
Remove joint (4) from valve mechanism cover (2). Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Thoroughly clean the valve mechanism cover. Clean the mating surfaces of the valve mechanism cover base.
Illustration 2 g01353908
Typical example
Install a new joint (4) to valve mechanism cover (2). Note: Ensure that the joint is fully seated into the groove of the valve mechanism cover.
Illustration 3 g01269961
Typical example
Ensure that harness assemblies (6) are not in contact with the rocker arms or in contact with the valve mechanism cover base. Position valve mechanism cover (2) onto valve mechanism cover base (5). Ensure that harness assemblies (6) are not trapped during the assembly procedure. Install bolts (1) and (3).

Tightening sequence for the valve mechanism cover
Tighten bolts (1) and (3) in the numerical sequence that is shown in Illustration 4. Tighten the bolts to a torque of 6 N m (53 lb in).
If the valve mechanism cover is equipped with a heat shield, install the heat shield. Tighten the bolts to a torque of 9 N m (79 lb in). End By:
Connect the crankcase breather or install the crankcase breather. Refer to Disassembly and Assembly, "Crankcase Breather - Install".
