Installation
cap/breather. The filler cap may be located in the adapter
casting between the UP and DN ports, next to the DN port on
the motor side, or in the reservoir.
The type of fluid must be compatible with the Nitrile (Buna
N) seals used on the power unit, and must comply with the
recommendations of the manufacturers of the component
parts. Acceptable fluids include standard Automatic
Transmission Fluid (ATF) and most mineral based hydraulic
fluids with viscosities between 32 cSt (150 SSU) and 64 cSt
(300 SSU) at 38°C (100°F). For fluids other than these, contact
Parker Oildyne with the details. If users wish to use alternative
oil, hydraulic fluid or ATF, they are warned to check that they
have the same properties as those recommended.
Parker
Oildyne takes no responsibility if unapproved alternatives
are used.
Reservoir Filling
The filler location may be between the UP and DN ports as
shown in 1) below, next to the DN port on the motor side as
shown in 2) or in the reservoir as shown in 3), 4) and 5):
1) Will be either a 1/8-27 NPT thread with an 11 mm (7/16 in) hex
head or a 1/4-18 NPT thread with a 14 mm (9/16 in) hex head.
Tighten until snug. See below:
2) A breather/dipstick is installed in 108/118 Series Power Units
using the ‘A’ and ‘B’ reservoirs in a vertical configuration. The
dipstick head requires a flat-blade screwdriver with a blade
width of between 9-13 mm (.35 to .5 in). After filling, with the
dipstick tightened all the way in, loosen the dipstick by 1.5 turns
to enable the breather function. See below:
3) 1/4-18 NPT thread with a 14 mm (9/16 in) hex head. Tighten
until snug. See below:
4) The cylindrical steel reservoirs have filler/breathers with a
3/8-18 NPT thread. The head of the breather is circular allowing
the breather to be removed and installed by hand only – no tools
are necessary. Tighten until snug. See below:
5) The rectangular plastic reservoirs have a filler/breather
which is a ‘push in/pull out’ design, installable by hand – no
tools are required. See below:

Vertical Mount (approximate)
In general, when filled to about 12 mm (.5 in) from the filler port
location.
Exceptions:
A and B reservoirs filled to “FULL” mark on dipstick.
P, Q, R and S tanks filled to the shoulder below the filler/
breather. See below:

In general, when filled to about 12 mm (.5 in) from the filler port
location.
Exceptions: when the filler port is located between the UP and
DN ports, fill until oil just becomes visible. See below:
