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 right rear side of the 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-H-5606,
through the filler hole until full. Reinstall the filler plug and tighten.
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.
ELECTRICAL SYSTEM.
Servicing the electrical system involves adding distilled water to the battery to maintain correct electrolyte
level and checking cable connections and for any spilled electrolyte that would lead to corrosion. The security
of all electrical connections should be checked as well as the operation of all lights, general condition of the
alternator and starter. All electrical wires should be inspected for chafing and bare wires. For detailed
information on this system, refer to Chapter 24 of this manual.
BATTERY.
Access to the battery is through the aft side of the baggage compartment on the PA-28RT-201T and located
in the engine compartment on the PA-28RT-201. The battery is enclosed in a thermoplastic box on the PA-
28RT-201T and a stainless steel box on the PA-28RT-201 with a vent system and a drain. The vents allow fresh
air to enter the box and draw off fumes that may accumulate due to the charging process of the battery. The
drain is clamped off and should be opened occasionally to drain any accumulation of liquid or during cleaning
of the box. The battery should be checked for fluid level but must not be filled above the baffle plates. A
hydrometer check should be performed to determine the percent of charge in the battery. All connections must
be clean and tight.
INDUCTION AIR FILTER.
REMOVAL OF AIR FILTER.
The location of the PA-28RT-201 filter is on the left side and just in front of the firewall. The PA-28RT-
201T filter is located just in front of the firewall above the turbocharg e r. Remove filter by the following
procedure:
1. Remove upper engine cowl.
2. Loosen studs and carefully move the cover assembly aside.
3. The filter is now free for removal. Clean or replace the filter.
