SPOOL - CAP (Hyster HY0288473)

A damaged spool cap can cause fluid leakage and loss of control in the valve assembly. The spool cap serves as a sealing and retaining component for the valve spool, ensuring proper alignment and containment of pressurized fluid. This aftermarket replacement part references Hyster catalog number HY0288473. The cap's mechanical function is to secure the spool within its bore while providing a sealing surface. A common failure consequence is external leakage, which reduces system efficiency and may lead to erratic operation. During routine service, a worn cap may allow contamination ingress, accelerating internal wear. Verify the serial number or application, then call (562) 693-7748.
