12.10 TRANSMISSION OIL SYSTEM
The transmission sump case serves as the
reservoir for this system. The filler is located on
the upper right side of the transmission and is
accessible when the forward pylon fairing is
opened. Oil level sight gages may be viewed
through right side of pylon support structure in
cabin with aid of a light controlled by a push-button
switch. A sump drain valve is located directly
beneath the sump. An external filter, in return line
from oil cooler, is located inside pylon structure at
right side and has a red indicator which will be
visible when filter is in impending bypass
condition. Drain valves in oil collector lines are
accessible through bottom fuselage skin inboard
of F.S. 169.0. Refer to Table 12-1 (or MDL-D212-
725-1) for list of approved oils and for location of
filler. Maintenance practices are contained in
Chapter 63.
12.11 TRANSMISSION OIL SYSTEM -
SEEPAGE RATES
Main transmission oil seepage shall not exceed
two drops per minutes from any single source or
shall not exceed a total of 15 drops per minute
from all sources on transmission.
12.12 TAIL ROTOR GEARBOXES
Oil level in the intermediate and tail rotor
gearboxes may be checked on the sight gages
and replenished, as required. Intermediate
gearbox and tail rotor gearbox maintenance
practices are contained in Chapter 63. Refer to
Table 12-1 (or MD-D212-725-1) for list of
approved oils.
12.13 TAIL ROTOR AND INTERMEDIATE
GEARBOX OIL SYSTEMS - SEEPAGE RATES
Gearbox oil seepage shall not exceed 2 drops per
minute from any single source or shall not exceed
a total of 6 drops per minute from all sources on a
gearbox.
12.14 MAIN ROTOR HUB
Transparent plastic sight gauges are on grip and
pillow block reservoirs for checking oil level. Oil
level shall be maintained at one-half indication.
Refer to Table 12-1 (or MD-D212-725-1) for
approved lubricants.
12.15 STABILIZER BAR DAMPERS
CAUTION
ONLY USE HYDRAULIC FLUID (C-002) MIL-PRF-
5606 WHEN SERVICING THE STABILIZER BAR
DAMPERS. USE OF HYDRAULIC FLUID (C-072)
MIL-PRF-87257 IS NOT AUTHORIZED.
Check timing and service only as necessary
(Chapter 62).
12.16 HYDRAULIC SYSTEM
Access to hydraulic reservoirs is gained by opening
forward pylon fairing. The hydraulic system 1
reservoir is on right side and the hydraulic system 2
reservoir is on left side. Pressure and return filters,
with red pop-out indicators that will be visible when
filter requires change, are located in integrated
valve and filter assemblies in pylon. The hydraulic
system 1 integrated valve and filter assembly is
located at lower front center of lift beam. The
hydraulic system 2 integrated valve and filter
assembly is aft of lift beam on left side of pylon.
NOTE
When adding hydraulic fluid, the same specification
of hydraulic fluid already used in the system shall
be used. However, in circumstances where
emergency top-off or inadvertent mixing may occur,
it is acceptable to use hydraulic fluid of the other
approved specification. No further maintenance
action will be required. To change the specification
