HYDRAULIC HOSES
The MMP4 is equipped with hydraulic hosing to
convey the hydraulic oil pressure and flow to
components that are operated by the hydraulic
control valve. These hoses are sized according to the
volume and pressure requirements of the
component. The hydraulic drive motor for the water
pump utilizes a 1 inch (-16) hose to direct the volume
of oil required to turn motor that drives the impeller
of the water pump at the rated speed. The hydraulic
cylinder hoses require a smaller volume of fluid and
do not require as large of a hose. The makeup oil
requirement for the lift cylinders (when the booms
move down) are low pressure and low volume. The
suction side of the hydraulic pump requires suction
rated hydraulic hose, this prevents the hose from
collapsing under suction loads.
INSPECTION
Inspect for damage, security, and leaks.
REPAIR
1. Remove and replace damaged hose assembly if
damage to outer covering is present or leaks are
present.
2. Replace hose assembly if hose end is
unserviceable due to leaks or damage.
