BLOWER RELIEF VALVE
The relief valve is a constant pressure style meaning the pressure will remain at a minimum of 6 psi when
popping open because of high excessive pressures. High excess pressures are generally caused by plugged
or kinked hoses. Check the function of the valve as indicated next.
Once weekly, plug feeder outlet or end of material hose with blower only running. The spring loaded relief
valve 34 should open. Cycle valve several times by plugging and unplugging feeder outlet or hose to clear
the valve of any build-up of dirt or material. Be sure the air bleed control valve 15 is fully closed.
Note pressure reading on the air gauge
30
at the moment the spring
loaded valve relieves. The indication should be 6 psi. The pressure
reading will drop the moment the spring loaded valve pops while the
blower is still running because the valve is designed to dump full blower
air capacity. Any significant difference over 1.0 psi should be reported
to the factory. Never attempt to readjust the spring loaded relief valve
without consulting the factory.
CAUTION: Do not grease or oil since the relief valve will not function
other than completely dry.
ROLLER CHAIN IDLER ASSEMBLY
Spray a light misting oil on all mechanisms that make up the auger
drive chain idler assembly
48
and airlock feeder drive chain idler
assembly
49
. For any reassembly that may occur, make sure that
the idler arm swivels freely without wobble and that the spring is
compressed to a 1" length between the two control washers.
The spring length is 2-1/2 inches non-compressed.
OGURA ELECTRO-MAGNETIC CLUTCH
This clutch has no scheduled wear replacement parts and can only be replaced whenever field failures may
occur. Extensive testing was performed at the factory and CTMW feels it has found a very suitable clutch
that will provide a long service life.
CLUTCH TORQUE ARM
Check the condition of the torque arm assembly that retains the clutch field assembly from rotating. Look
for elongated holes in the arm, worn bolts, and worn bushings.
