What should technicians check when a Liebherr LR622, LR622B, LR632, or LR632B has weak or slow hydraulic functions?
When a Liebherr LR622, LR622B, LR632, or LR632B crawler loader develops weak travel or working-hydraulic performance, technicians should systematically inspect fluid condition, filters, hydraulic pressures, pumps, valves, controls, and related components rather than replacing parts based only on symptoms. The service manual contains dedicated sections for travel hydraulics, working hydraulics, and hydraulic components to support systematic diagnosis.
These systems and sections are documented in available listings for the LR622/LR622B/LR632/LR632B workshop manual.
