Removal Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g03382451
Disconnect the breather hose from the separator for the crankcase breather. Refer to Disassembly and Assembly, "Crankcase Breather - Remove" for the correct procedure.
Remove bolts (1) and bolts (2) from valve mechanism cover (3). Note: The bolts are of two different lengths. Note the positions of the different bolts.
Remove valve mechanism cover (3) from valve mechanism cover base (5).
Remove gasket (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" for the correct procedure. Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Thoroughly clean all gasket surfaces of the valve mechanism cover. Clean the gasket 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" for the correct procedure.
