V. HYDRAULIC SYSTEM.
The hydraulic pump and landing gear actuating cylinders should be checked for leaks, tightness of line
fittings and general condition. The cylinder rods are to be free of all dirt and grit. To clean the rods, use an
oil soaked rag and carefully wipe them. All the hydraulic lines should be checked for leaks, kinks,
corrosion and attachment fittings for tightness and security. Repair and check procedures for the hydraulic
pump, cylinders, and various components may be found in Chapter 29.
W. SERVICING HYDRAULIC PUMP/RESERVOIR.
The fluid level of the reservoir of the combination pump and reservoir should be checked every 50 hours
by viewing the fluid through the filler plug hole in the hydraulic pump. Access to the pump is through the
panel at the left side of the forward baggage compartment.
A small vent hole is located under the vent screw head. Retain
.015 inch clearance between the screw head and the small vent
hole.
To check fluid level, remove the filler plug located on the forward side of the pump and ascertain that fluid
is visible up to the bottom of the filler plug hole. Should fluid be below the hole, loosen the vent screw and
add fluid, MIL-H-5606, through the filler hole until full. Reinstall the filler plug.
