Type: Hydraulic cylinder bore seal kit (piston/barrel seals only — not a complete rod + bore kit)
Bore: 90mm
Weight: 0.08 lbs
Cylinder Applications: Loader bucket tilt, backhoe stabilizer, backhoe thumb, skid steer bucket (RH/LH) — verify your specific cylinder and serial number before ordering
Note: This is the bore seal kit only. A separate rod seal kit may be required for a complete cylinder rebuild. Verify your cylinder number and machine serial number before ordering.
Condition: Aftermarket replacement part
Common Use Case or Symptoms: Use when the cylinder is bypassing internally — loss of lift or curl force, slow or drifting loader/backhoe movement under load, or cylinder rod extending under its own weight with no control input — all indicate worn or failed bore (piston) seals. Internal bypass does not typically cause visible external leaking; a rod seal leak requires the companion rod seal kit. Replace bore seals when internal bypass is confirmed through a cylinder drift or bypass test.
