Part Numbers: 65516840, 65516740, 90774240
Common Failures & Diagnostics
Single function weak or slow movement: Caused by worn spool, overload relief valve, or pressure compensator.
Boom/arm drift: Test cylinder seals first, then inspect anti-drift valves.
All functions slow & low pressure: Check main relief valve, LS bypass valve, and unloading valve.
Jerky combined operation: Metal contamination, stuck pressure compensator, or LS shuttle valve.
External oil leakage between valve stacks: Failed O-rings.
High hydraulic oil temperature: Severe internal leakage or continuous relief.
Important: This is a heavy mining sectional CLSS valve. Pressure testing is mandatory before ordering valve assembly to avoid misdiagnosis.
