SANY Genuine Hydraulic Return Filter (B222100000233 / 60101256)
The SANY Genuine Tank-Internal Hydraulic Return Filter (B222100000233 / 60101256) is a critical component for SANY's legacy excavators. Positioned at the end of the main control valve return line, it captures metallic shavings and rubber fragments before they re-enter the reservoir, protecting pump and valve longevity.

Maintenance & Professional Installation
Guidelines:
Preparation: Retract all cylinders fully and bleed tank pressure before opening the cover.
Diagnostics: Inspect the old filter for metal shards—large amounts indicate impending pump/motor failure.
Seal Change: Always replace the housing O-ring with a new Viton seal.
Service Cycle: 500 hours (break-in), then 2000 hours (standard) or 1000–1500 hours (harsh/quarry conditions).
Air Purge: Run at low idle for 5 minutes post-installation to vent air before applying load.
