HUB AS-YM 3089868 - Caterpillar

Removal Procedure
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.
Drain the coolant from the cooling system to a level below the water temperature regulator, into a suitable container for storage or for disposal. Refer to Operation and Maintenance Manual, "Cooling System Coolant - Change" for the correct draining procedure.
Remove the wastegate regulator valve. Refer to Disassembly and Assembly, "Wastegate Solenoid - Remove and Install" for the correct procedure.

Typical example
Loosen the hose clamps from the upper radiator hose and disconnect the upper radiator hose from water temperature regulator housing (1).
Loosen clamp (3) and disconnect exhaust gas recirculation (EGR) cooler hose (2) from water temperature regulator housing (1). Position the EGR cooler hose away from the water temperature regulator housing.
Slide the locking tab into the unlocked position and disconnect the wiring harness from coolant temperature sensor (4).
Remove bolts (6) and remove bolts (7) from water temperature regulator housing (1).
Remove water temperature regulator housing (1) from the cylinder head.
Remove gasket (5) (not shown).
If necessary, remove the coolant temperature sensor. Refer to Disassembly and Assembly, "Coolant Temperature Sensor - Remove and Install" for the correct procedure. Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Ensure that all components are clean and free of wear and damage. If necessary, replace any components that are worn or damaged.
Check the water temperature regulator for correct operation. Refer to System Operation, Testing, and Adjusting, "Water Temperature Regulator - Test" for the procedure to test the water temperature regulator. If the water temperature regulator is not operating correctly, the complete assembly must be replaced.
If necessary, install the coolant temperature sensor. Refer to Disassembly and Assembly, "Coolant Temperature Sensor - Remove and Install" for the correct procedure.

Typical example
Position gasket (5) (not shown) onto water temperature regulator housing (1). Note: Ensure that the gasket is correctly orientated.
Install bolts (7) to water temperature regulator housing (1).
Position water temperature regulator housing (1) onto the cylinder head.
Install bolts (6) to the water temperature regulator housing finger tight.
Tighten the bolts (6) and bolts (7) to a torque of 25 N m (221 lb in).
Connect hose (2) to the water temperature regulator housing and tighten clamp (3) securely.
Connect the upper radiator hose to water temperature regulator housing (1) and tighten the hose clamps securely.
Connect the wiring harness to coolant temperature sensor (4). Slide the locking tab into the locked position.
Install the wastegate solenoid. Refer to Disassembly and Assembly, "Wastegate Solenoid - Remove and Install" for the correct procedure.
Fill the cooling system to the correct level. Refer to Operation and Maintenance Manual, "Cooling System Coolant - Check" and Operation and Maintenance Manual, "Cooling System Coolant - Change" for the correct filling procedures.
