7442T32 Mercury PISTON

Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
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.
If necessary, remove the brackets for the Clean Emission Module (CEM). Refer to Disassembly and Assembly, "Support and Mounting (CEM) - Remove and Install" for the correct procedure.
If necessary, remove the air cleaner bracket. Refer to Disassembly and Assembly, "Air Cleaner- Remove and Install" for the correct procedure.

Remove nuts (12) from valve mechanism cover (9). Note: Loosen the nuts evenly in order to avoid distortion of the valve mechanism cover.
Remove sealing washers (13) (not shown) from the studs.
Remove valve mechanism cover (9) from valve mechanism cover base (15).
Remove gasket (14) (not shown) from valve mechanism cover (9).
If necessary, remove connection (11) from valve mechanism cover (9). Note: Make temporary marks on the connection and the valve mechanism cover to show orientation of the connection for installation purposes.Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 3 g03339525
Ensure that valve mechanism cover (9) is clean and free from damage. Clean the gasket surface of valve mechanism cover base (15).
If necessary, install connection (11) to valve mechanism cover (9). Tighten the connection to a torque of 20 N m (177 lb in). Ensure that the connection is correctly orientated.
Install a new gasket (14) (not shown) to valve mechanism cover (9). Ensure that the gasket is correctly seated into the recess of the valve mechanism cover.
Position valve mechanism cover (9) onto valve mechanism cover base (15).
Install new sealing washers (13) (not shown) onto the studs.
Install nuts (12) finger tight.
Tighten evenly nuts (12) to a torque of 14 N m (124 lb in). Note: Tighten the nuts evenly in order to avoid distortion of the valve mechanism cover.
Repeat Step 7 in order to ensure nuts (12) achieve the correct torque values.
Illustration 4 g03339524
Connect harness assembly (4) to harness assembly (10). Install harness assembly (10) to clip (5).
Connect hose assembly (2) to close circuit breather canister (6) and valve mechanism cover (9). Ensure that the hose clamps are correctly orientated.
Securely tighten hose clamp (1) and hose clamp (3) for hose assembly (8).
Connect hose assembly (3) to close circuit breather canister (6). Ensure that the hose clamp is correctly orientated.
Securely tighten hose clamp (7).
If necessary, install the brackets for the Clean Emission Module (CEM). Refer to Disassembly and Assembly, "Support and Mounting (CEM) - Remove and Install" for the correct procedure.
If necessary, install the air cleaner bracket. Refer to Disassembly and Assembly, "Air Cleaner- Remove and Install" for the correct procedure.
