Excessive friction between piston shoes and swash plates drops pump pressure, causing slow excavator response and heavy fuel losses. Weak slippers crush or split under violent hydraulic spikes. For fleet operations using SK200-6 or DH220 machines, one damaged shoe triggers widespread metal grinding, ruining expensive main pump rotating groups.
