ACTION REQUIRED

Show/hide table

If the hydraulic performance is slow, jerky, and/or the hydraulic power feels low, inspect the components in the 276-0155 or 253-7766 Valve Group (the implement pump compensator valve) for damage. If any components show signs of damage, replace them with the appropriate group of parts listed above. Tighten the 165-9407 Plug to 100 Nm in order to prevent future loss of pre-load. Refer to the machines service manual as needed.
