243299 Volvo.Penta O-ring

At operating temperature, the engine coolant is hot and under pressure. Steam can cause personal injury. Check the coolant level only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand. Remove the fill cap from the radiator slowly to relieve pressure. Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to prevent personal injury.
3. Drain the coolant from radiator into a suitable container. The capacity of the cooling system is 30.0 liters (8 U.S. gallons).
At operating temperatures, the oil tank is hot and under pressure. Hot oil can cause burns. Remove the fill plug only when the engine is stopped and when the fill plug is cool enough to touch with your bare hands.
Identify all hydraulic lines as they are removed for reinstallation purposes. Cap and plug all lines and fittings to prevent any contaminants from entering the system.4. Release the pressure in the hydraulic system by slowly loosening the fill cap located on the top of the hydraulic oil tank.5. Drain the hydraulic oil from the hydraulic oil tank. The capacity of the hydraulic oil tank is 80 liters (21.1 U. S. gallons). Use steps 6 through 14 only if the machine is equipped with air conditioning. 6. Disconnect two electrical connectors (2).7. Remove the bolt from air conditioner compressor strap (1).8. Remove bolt (3) and remove air conditioning unit. Move the air conditioning unit out of the way. 9. Remove three clamps (4) from two hose assemblies (5). 10. Turn shut off valves (8) off.11. Disconnect two hose assemblies (7) from shut off valves (8). Plug hose assemblies immediately.12. Remove clamp (6) from two hose assemblies (7). 13. Remove clamps (9) from two hose assemblies (5) and (7). 14. Remove clamps (10) from two hose assemblies (5) and (7). 15. Disconnect air indicator tube (11) from the hydraulic oil tank frame.16. Loosen the clamp, and remove coolant hose (12) from the top of the hydraulic oil tank frame.17. Remove the three bolts that fasten air cleaner bracket (14) to the hydraulic oil tank frame.18. Remove oil level indicator (13).19. Disconnect two fuel lines (15) from the engine. Cap and plug immediately. 20. Disconnect three electrical connectors (16).21. Disconnect three wires (17) from the fuel shutoff solenoid.22. Remove the cable ties that fasten wiring harness (18) to the engine. Move the wiring harness out of the way.23. Disconnect four hose assemblies (19) from the steering pump. Cap and plug immediately. 24. Disconnect wire (20) from the engine heater.25. Disconnect electrical connector (21).26. Disconnect two wires (22) from the alternator.27. Remove the cable ties that fasten wiring harness (23) to the engine. Move the wiring harness out of the way.28. Loosen the clamp, and remove coolant hose (24) from the engine. 29. Remove five wires (25) from the starter.30. Remove the nut, and remove cover (26) from the starter.31. Remove the remaining two wires from the starter. 32. Disconnect hose assemblies (27) and (28) from the vibratory pump. Cap and plug immediately. 33. Disconnect two hose assemblies (29) from the vibratory pump. Cap and plug immediately.34. Disconnect two electrical connectors (30). 35. Disconnect hose assemblies (31) and (32) from the propel pumps. Cap and plug immediately. 36. Disconnect hose assemblies (33), (36), (37) and (39) from the propel pumps. Cap and plug immediately.37. Remove the cotter pin and pin that fastens control cable (38) to the propel pump. Loosen the jam nut and remove control cable (38) from the bracket. Move the control cable out of the way.38. Mark electrical connectors (34) for assembly purposes. Remove the screws that fasten electrical connectors (34) to the control valves on the propel pumps. Remove the electrical connectors from the propel pumps.39. Remove the cable ties that fasten wiring harness (35) to the pumps. Move the wiring harness out of the way. 40. Attach a Tooling (A) and a hoist to the engine as shown. Remove four mounting bolts (41), and remove engine (40) and the pumps as a unit from the machine. The weight of the engine and pumps as a unit is approximately 726 kg (1600 lb). For the installation of the engine, reverse the removal steps. After the engine has been installed, fill the cooling system with coolant to the correct level. Fill the hydraulic oil system with hydraulic oil to the correct level. See the Operation & Maintenance Manual, Form No. KEBU7503, for the correct procedures.End By:a. * tilt operators platform or lower cab*This procedure is in the Machine Systems Disassembly & Assembly module, Form No. KENR7037.
