HYDRAULIC MAINTENANCE
There are four items of routine maintenance associated with the hydraulic system of the V-18 II. With proper
maintenance the hydraulic system of the V-18 should provide years of reliable service.
1. OIL FILTER
- Ten micron filtration of the hydraulic oil is provided by a spin on type filter 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
consumption will be very low and it should be unnecessary to add oil more often than at filter changes. Add oil
only to the top line on level gauge. The hydraulic tank capacity is 8 US gallons.
NOTE:
The V-18 II is shipped from the factory with Conoco Super Hydraulic 46 oil. Generally any brand of
recognized mineral hydraulic oil with the same properties should be compatible with Conoco Super Hydraulic 46
oil, but to avoid any risk we suggest staying with Conoco Super Hydraulic 46. If it is desirable to change brands,
it is necessary to drain the tank and to fill to1/3 with the new oil. Operate through several full strokes of each
cylinder, drain the tank again, and finally fill 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 temperature should never exceed 160 F°.
4. OIL PRESSURE
- Oil pressure is factory set to 650 psi and should not require further attention.
Hydraulic tank and manifold assembly are
mounted on a door located on the infeed
side of the base. The level and tempera-
ture gauge is found on the front of the
door.
