PA-32R

2-64. SERVICING HYDRAULIC SYSTEM. The general condition of the hydraulic pump and landing gear

actuating cylinders should be checked. Ensure that there are no leaks and that the line fittings are tight.
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 also be checked for leaks, kinks, and corrosion. Check the
tightness of the attachment fittings.

The gear back up extender actuator assembly is located beneath the floorboard of center seats and should
be checked to determine that it is operating properly. The diaphragm shaft may be operated by hand to
make sure that it is free to fluctuate and that the actuating arm and its components are operating freely.
Check the pressure housing assembly for cracks, breaks, or fatigue. Check to ensure that the hydraulic
valve and fittings are free of leaks.

Repair and check procedures for the hydraulic pump, cylinders and various components may be found in
Section VA of this manual.

2-65. 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 forward baggage
compartment.

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, add fluid, MIL-
PRF-5606, through the filler hole until full. Reinstall the filler plug and tighten.

NOTE: A small vent hole is located under the vent screw head. Retain 1/64 inch clearance between the

screw head and the small vent hole.

2-66. BATTERY.

2-67. SERVICING BATTERY. Servicing of the battery, which is located under the floor panel of the forward

baggage compartment, involves adding distilled water to maintain electrolyte even with the horizontal
baffles, checking cable connections, and checking for any spilled electrolyte that would lead to
corrosion. A check for proper fluid level and presence of corrosion should be conducted at intervals of
50 hours or 30 days, whichever comes first. When corrosion is found, at each 100 hour inspection or
every 90 days, the battery should be removed from the box, and the battery and box should be cleaned.
Removal, cleaning and charging instructions may be found in Section X of this manual.
