To access the two idler wheel slide as-
sembly grease nipples the wheel must
be removed. A exible grease gun hose
with a 45
o
tting is required to apply the
grease.
Hydraulic tank and manifold assem-
bly are mounted on a door located
on the infeed side of the base. The
level and temperature gauge is
found on the front of the door.
HYDRAULIC MAINTENANCE
There are four items of routine maintenance associated with the hydraulic system of the V18 APC. With proper mainte-
nance the hydraulic system of the V18 APC should provide years of reliable service.
1. OIL FILTER - Ten micron ltration of the hydraulic oil is provided by a spin on type lter mounted on the tank
return line as shown below. The element should be changed every 500 working hours or a minimum of at least
once per year. Suitable replacement elements are:
CANFLO - RSE-30-10
GRESEN - K-23018
LHA - SPE-15-10
ZINGA - AE-10
2. OIL LEVEL - Oil level should be maintained in the upper half of the level gauge. Normally the rate of oil consump-
tion will be very low and it should be unnecessary to add oil more often than at lter changes. Add oil only to the
top line on level gauge. The hydraulic tank capacity is 8 US gallons.
NOTE:
The V18 APC is shipped from the factory with Texaco Rando HD 46 oil. Generally any brand of recognized mineral hy-
draulic oil with the same properties should be compatible with Texaco Rando HD 46 oil, but to avoid any risk we suggest
staying with Texaco Rando HD 46. If it is desirable to change brands, it is necessary to drain the tank and to ll to 1/3 with
the new oil. Operate through several full strokes of each cylinder, drain the tank again, and nally ll the tank with the new
brand.
Recommended replacement oils:
Chevron - AW Hydraulic Oil 46
Texaco - Rando HD 46
Mobil - Mobil DTE 25
Esso - NUTO H46
Shell - Tellus 46
3. OIL TEMPERATURE - Oil temperature is indicated by a thermometer
contained in the level gauge. Oil temperature during steady operation
should stabilize at about 50 - 55°F above room temperature. Thus in a
70°F shop one might expect an oil temperature of about 120°F. Oil tem-
perature should never exceed 160 F°.
OIL PRESSURE - Oil pressure is factory set to 900 psi and should not require
further attention.
