JCB Transmission Output O-ring 45x4mm - OEM 10/907473
The OEM-quality gearbox output sealing O-ring is a static and dynamic sealing element used in the drive systems of JCB JS series excavators. It is responsible for maintaining a tight seal at the interface between the gearbox housing and the output shaft, preventing gear oil leaks and protecting the internal mechanism from water, dust, and external contaminants.
Technical Specification:
- Dimensions: 45 mm (internal diameter) x 4 mm (thickness/cross-section).
- Application: Drive gearbox output shaft sealing.
- Material: Elastomer with high resistance to abrasion and high oil temperatures.

Workshop Tip: An oil leak from the gearbox output area often indicates wear of the O-ring or oil seals. When replacing the seal, it is essential to inspect the shaft surface—any scratches or pitting can lead to rapid damage of the new component. Before installation, it is recommended to lubricate the O-ring with fresh gear oil to prevent twisting or pinching during seating in the housing.
