the hydraulic oil return line. Flow rating of the
fi
l-
ter must be equal to, or greater than, the maxi-
mum GPM at which the system will be operated.
IMPORTANT
Use only a
fi
lter that is speci
fi
cally intended for
hydraulic systems.
3.4.2 HYDRAULIC OIL RESERVOIR
3.4.2.1 DETERMINING
RESERVOIR
SIZE
In a conventional hydraulic system, minimum
tank size, in gallons, should be equal to the max-
imum GPM
fl
ow rate, times two (x 2).
3.4.2.2 DETERMINING
RESERVOIR SHAPE
The reservoir structure should be tall and narrow
rather than shallow and broad (
Figure 3-4
). A tall,
narrow tank is recommended because:
1. The oil level is well above suction line open-
ing, avoiding the possibility of drawing air into
the pump due to a vortex or “whirlpool” e
ff
ect
within the tank during operation
fl
ow.
2. Allows for better oil level tolerance level of
the system if vehicle operates at an unusual
(slightly o
ff
level) vehicle angle.
3. To keep return
fl
ow well below the surface so
it does not break the surface and cause aer-
ation (cavitation) of the oil.
3.4.2.3 MANDATORY
RESERVOIR
FEATURES
• The reservoir should incorporate the following
design features:
• In terms of location of the reservoir tank within
the hydraulic system, note that the hydraulic
pump’s inlet line (suction line out from the res-
ervoir to the pump) should be located near the
bottom of the tank, well below the oil level. The
suction line should protrude a minimum of two
(2”) inches into the reservoir to keep it away
from potential contaminant surface buildup.

NOTE:
The dimensions listed above are the minimum required clearance
distances needed for properly cooling the machine. Additinal clearance
room may be desired for easier acess for control and/or maintenance
functions.
IMPORTANT
Additional allotted dimensions/surroundings
space of package must allow for continu-
ous circulation of air around and through
the machine for cooling purposes. DO NOT
install in an enclosed area.
