HMT36FA pump losing flow or piston shoes making noise at high pressure on your ZX200-3 or ZX210-3? A worn 8099321 piston slipper allows the shoe to tilt off the swash plate, causing rapid internal leakage and scoring the barrel bores. RITO supplies this Handok-grade piston slipper set to restore the flat shoe-to-plate contact that keeps the HMT36FA pump efficient.

In Stock8099321 Piston Slipper (Piston Shoe) for Hitachi HMT36FA piston pumps on ZX200-3, ZX210-3, ZX225, ZX240 and ZX200-5G excavators. The piston shoe maintains hydrostatic film contact with the swash plate across the full stroke. Its flat bearing face diameter, retainer clearance and bronze slipper material must all be correct to avoid the tilting that re-scores a new swash plate within hours.

| Condition | 100% New Aftermarket OEM Quality |
| Packaging | Wooden Case Reinforced Carton Neutral Packing Customized Box |
Bearing face lapped to Ra 0.2 and flatness within 1 micrometre, establishing the hydrostatic oil film that prevents dry metal-to-metal contact at high swash plate pressure.
Slipper retainer bore machined to HMT36FA OEM clearance, preventing the slipper tilt that causes edge loading and swash plate scoring.
Phosphor-bronze alloy selected to Handok specification for conformability against the swash plate surface, extending service life under HMT36FA peak pressure cycles.
Supplied in sets to allow complete rotating group replacement, eliminating the mixed-wear condition that results from fitting new shoes alongside worn pistons.
FAQ
Q: How do I know when the 8099321 piston shoes need replacing on my ZX200-3?
A: Pump case-drain flow test shows above-spec leakage, swash plate shows radial scoring marks from slipper edge loading, visible bronze debris in the drain oil, and pump makes a knocking sound at high pressure during stall tests.
Q: Should I replace the swash plate at the same time as the 8099321 piston shoes?
A: If the swash plate shows scoring or groove marks from slipper edge loading, replace it together with the piston shoes. New shoes on a scored swash plate will immediately develop the same edge loading pattern.
Q: How many piston shoes does the HMT36FA pump have?
A: The HMT36FA uses 9 pistons. Replace all 9 shoes as a set. Mixing new and worn shoes creates uneven load distribution that accelerates wear of the new shoes and re-scores the swash plate.
Q: How to confirm 8099321 fits my ZX200-3 HMT36FA pump?
A: Match the existing slipper part number 8099321 and confirm pump model is HMT36FA. Provide pump serial number to our team for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.

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.
