Product Operate Guide

Common faults and manifestations

① Return sleeve wear

→ Walking weakness, reduced pressure, and increased internal leakage.

② The clearance between plunger fittings is too large

Vibration, increased noise, and decreased efficiency.

③ Wear or detachment of sliding shoes

The roughness of the distribution plate, if severe, can lead to the scrapping of HST.

④ Spring fatigue

The return speed of the plunger decreases, manifested as:

Slow vehicle movement

Heat increase

Reduced system efficiency
