CARRIER-PLANETARY 8D2532 - Caterpillar

Removal Procedure
Start By:
Remove the inlet air control (NRS Induction Mixer). Refer to Disassembly and Assembly, "Inlet Air Control (NRS Induction Mixer) - Remove" for the correct procedure.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g02173456
Disconnect plastic tube assembly (2) from the crankcase breather on valve mechanism cover (7). Refer to Disassembly and Assembly, "Crankcase Breather - Remove" for the correct procedure.
Remove bolt (3) from clip for tube assembly (4).
Remove bolt (5) from clip for tube assembly (6).
Remove bolt (8) and position pressure sensor manifold (1) away from valve mechanism cover (7).
Remove bolts (9) from valve mechanism cover (7).
Remove valve mechanism cover (7) from the cylinder head. Note: Remove the valve mechanism cover vertically in order to avoid damage to the electronic unit injectors.

Remove gasket (10) from valve mechanism cover (7). Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 3 g02173457
Thoroughly clean all gasket surfaces of valve mechanism cover (7). Clean the gasket surfaces of the cylinder head.
Inspect gasket (10) for damage. If necessary, install a new gasket to valve mechanism cover (7). Note: Ensure that the gasket is fully seated into the groove of the valve mechanism cover.

Illustration 6 g02002834
Ensure that harness assemblies (12) are not in contact with rocker arms (11) or cylinder head (13). Note: Install the valve mechanism cover vertically in order to avoid damage to the electronic unit injectors.
Position valve mechanism cover (7) onto cylinder head (13). Ensure that harness assemblies (12) are not trapped during the assembly procedure.
Install bolts (9).
Tighten bolts (9) in the numerical sequence that is shown in Illustration 6. Tighten the bolts to a torque of 9 N m (79 lb in). Repeat Step 6 in order to ensure correct torque.
Position pressure sensor manifold (1) onto inlet elbow. Loosely install bolt (8).
Install bolt (3) to clip for tube assembly (4).
Install bolt (5) to clip for tube assembly (6).
Tighten bolt (8) to a torque of 22 N m (195 lb in).
Tighten bolt (3) and bolt (5) to a torque of 22 N m (195 lb in).
Connect plastic tube assembly (2) to the crankcase breather on valve mechanism cover (7). Refer to Disassembly and Assembly, "Crankcase Breather - Remove" for the correct procedure. End By:
Install the inlet air control (NRS Induction Mixer). Refer to Disassembly and Assembly, "Inlet Air Control (NRS Induction Mixer) - Install" for the correct procedure.
