Product: Complete orbitrol (steering unit) seal kit
For orbitrol part number: 35/410700
Applications
This complete orbitrol seal kit is designed for the hydraulic steering systems used in JCB machinery. The seals ensure internal tightness of the orbitrol, allowing precise metering of hydraulic oil to the steering cylinder and smooth, predictable steering response.
Worn or damaged seals cause internal pressure loss, reduced steering accuracy and external oil leaks. Replacing the seal kit is a standard and recommended overhaul procedure that restores full steering performance without the need to replace the entire orbitrol unit.
Function and Fault Diagnosis
Orbitrol seals are responsible for correct hydraulic oil distribution to the steering cylinder chambers. Seal wear typically results in:
⚠️ Safety Warning
A leaking or internally worn orbitrol is a serious safety risk. Loss of steering control may occur suddenly, especially during road travel or heavy-duty operation. Always rebuild the orbitrol in clean conditions and strictly follow manufacturer service procedures.
