Shacman X3000 TRUCK GRAMMER Seat Damper 6739159
FUNCTION
1. Vibration Absorption and Damping: As the core shock-absorbing component of the seat suspension system, it utilizes hydraulic damping principles to effectively absorb and control vertical vibrations and impacts acting on the seat, thereby preventing road irregularities from being directly transmitted to the driver's body.
2. Delivering a Smooth Ride: Working in conjunction with the seat's air suspension system, it rapidly attenuates seat rebound and oscillation, ensuring the seat remains relatively stable even on rough terrain and significantly enhancing comfort during prolonged driving.
3. Protecting Seat Structure: It cushions against excessive movement within the seat suspension system, minimizing fatigue damage to the air springs, mechanical springs, and other seat components, thereby extending the overall service life of the entire seat system.
Installation Location
It is installed beneath the driver's seat suspension system, positioned between the seat baseplate and the seat frame.
Its upper end connects to the upper seat frame (swinging structure) via a bolt or ball joint.
Its lower end connects to the lower seat baseplate or suspension base via a bolt or fork-end lug.
It operates in parallel with the seat air suspension bag to collectively absorb vertical vibrations.

Daily Maintenance Suggestions
It is recommended to inspect the unit every 10,000–20,000 kilometers or every 3–6 months (whichever comes first), in conjunction with routine vehicle maintenance.
Inspection Items:
Check the surface of the damper for any signs of oil leakage (oil stains are a common indicator of aging).
Observe whether the seat exhibits excessive vertical bouncing or a sensation of "bottoming out" (a hard impact) when driving over rough terrain.
Check if the mounting bolts or pins at both ends of the damper are loose.
Check the seat assembly as a whole for any abnormal noises.
