3.6.6 Oil Filter
Service Period : Oil and oil filter elements should be changed every 1500
hours. If regular quality viscosity checks or oil analyses are done with
satisfactory results, then longer periods of 3000 hours may be justified.
CAUTION: Do not use other than original oil filter element, as this will void all
warranty.
Equivalent oil filters are not necessarily satisfactory and may not have similar
seals, pressure rating or internal valves.
3.6.7 Lube Oil Pressure Adjustment
There are two relief valves in the crankcase. The first is situated in the oil pump
housing and is set at 65psig to protect the oil filter element. The second is
situated in the rear main bearing housing and is set at 50 - 55psig. This is to
relieve the oil from the seal housing and to ensure that the rear seal is cooled.
3.6.8 Oil Relief Valve Setting
Instructions
Cautionary Notes
Theory
1/. There are two oil pressure relief valves
fitted to the Rhino compressor. One is
located in the oil pump housing the other
in the flywheel bearing housing
(mechanical seal housing).
Both oil pressure relief valves are
adjustable by way of an Allen headed cap
screw located on the bottom edge of these
housings.
The relief valve in the flywheel bearing
housing should lift first to maintain
desired oil pressure. The oil pressure relief valve in the
flywheel housing must be fitted with a
lighter spring than that used in the relief
valve in the oil pump housing.
This ensures that there is oil pressure at all
parts of the lubrication system, and that
oil flows through the mechanical seal
cavity (aids in cooling)
Setting the Oil Pressure
2/. Screw both oil pressure adjusting screws
