Planetary Carrier 148-4637 Fit Caterpillar Excavator E318C 318E 319C 319D 320C 320D 320D2

Product Name: Swing Planetary Carrier (Assembly) Reference Part Number: 148-4637, 148-4632, 148-4633… Compatible Machine: Caterpillar Excavator E318C 318E 319C 319D 320C 320D 320D2… Description: The Swing Drive Planetary Carrier is responsible for controlling the rotational movement of the machinery’s swing system. It is a mechanical assembly designed to control and facilitate the rotational movement of the upper structure of heavy machinery, particularly in construction and excavation equipment. This component is a vital part of the swing drive system, which is responsible for the pivotal swing or rotation of the upper structure, including the cab, boom, and other attachments. The primary function of a swing drive planetary carrier is to distribute and transmit power from the swing motor to the machine’s upper structure. This rotation allows the operator to position the heavy equipment accurately, enabling tasks such as digging, lifting, and maneuvering. The planetary carrier contains a set of gears that distribute the torque evenly, ensuring smooth and efficient rotation. Parts Lists: 1. 094-0584 [6] WASHER (40.3X72X1-MM THK) 2. 094-1509 [3] SHAFT-PLANETARY 3. 148-4733 [3] GEAR-PLANETARY (26-TEETH) 4. 114-1581 [1] SPACER (57.5X74X6-MM THK) 5. 148-4732 [1] GEAR-SUN (20-TEETH) 6. 093-1729 [2] RING-RETAINING 7. 148-4632 [1] GEAR-SUN (23-TEETH) 8. 191-2578 [1] CARRIER-PLANETARY 9. 7Y-1434 [1] SPACER (40X69.5X6-MM THK) 10. 148-4637 [1] CARRIER-PLANETARY 11. 148-4640 [1] RING-RETAINING 12. 148-4643 [1] BEARING 13. 095-1022 [1] BEARING-ROLLER 14. 148-4642 [1] SEAL-O-RING 15. 227-6228 [1] CAGE 16. 453-3447 M [6] BOLT (M12X1.75X40-MM) 17. 451-2182 [6] WASHER-HARD (13.5X25.5X3-MM THK) 18. 199-4561 [2] SEAL-LIP TYPE 19. 148-4636 [1] SHAFT-PINION 20. 148-4638 [1] HOUSING 21. 3K-0360 [1] SEAL-O-RING 22. 6V-7238 [1] VALVE-SHUTOFF (SWING DRIVE) 23. 148-4634 [3] SHAFT-PLANETARY 24. 095-0891 [3] PIN-SPRING 25. 148-4635 [1] GEAR-RING (73-TEETH) 26. 148-4633 [3] GEAR-PLANETARY (25-TEETH) 27. 7Y-0252 [6] BEARING AS-ROLLER 28. 094-0611 [6] WASHER (47.3X76X1-MM THK) 29. 095-0886 [3] PIN-SPRING 30. 094-1516 [3] BEARING-ROLLER 31. 171-9383 [1] SPACER
