TOMAHAWK FAULT FINDING CHART – PART 2
Symptom Fault Possible Solutions
Shear bolt fails
repeatedly. Bolt bushes worn or damaged. Replace with new bushes.
Tailgate raised too high forcing bale into
crossbeater. Lower to tailgate allow material in bale
chamber to rotate freely.
Front half of large rectangular bale not
rotating freely. Lower the tailgate to allow material in bale
chamber to rotate freely and increase the bed
chain speed to encourage rotation of the front
half of bale.
Blades too aggressive. Reduce aggression of blades by sloping
backwards.
Single beater shear
bolt fails repeatedly One or more bale restraint fingers bent
and interfering with crossbeater. Straighten or replace damaged bale restraint
finger.
Chute and rotor blocks Chute exit blocked. Incorrect discharge rotor speed selected on
gearbox, check high rotor speed is selected.
Make sure material can leave the chute freely.
Material not flowing smoothly. Raise deflector to improve flow and rotate
chute to achieve desired delivery position.
Rotor speed low. Check that slip clutch is not slipping -
indicated by hot clutch assembly. Also
Increase engine speed.
Hydraulic valve fails to
operate Hydraulic connections to tractor faulty or
not connected. Rectify making sure pressure is applied to the
valve via the supply hose and that the return
line flow is not restricted.
Dirt or contamination in the
Bypass/Relief Valve in the flow control
slice. Firstly, remove the Bypass/Relief Valve from
the Flow Control Slice inspect for
contamination clean and replace. If problem
persists or re occurs regularly replace tractor
hydraulic oil with new clean oil.
Fit Inline Filter Kit.
Loss of operation of
rams and swivel slices.
Also operation of bed
in only 1 direction may
occur. Failure may be
sudden or deteriorate
slowly over a few days. Oil leaking from between slices of the
valve.
Internal failure in valve
Pilot cartridge contaminated.
Pilot manifold orifice blocked. See section below.
Contact manufacturer for advice.
Replace cartridge.
Replace manifold.
Oil leaking from
between slices of the
valve. Internal pressure in valve. Check return line hose connected and that
return line flow is not restricted by damaged
fittings or the tractor spool valve
Clamping bolts loose. Check bolts through valve tightened to correct
torque specified in the maintenance section.
Separation of slices in valve block as a
result of reverse oil flow (only when
connected to a double acting spool
valve). Fit return pipe to free flow return on tractor, or
fit check valve on outlet port to prevent
reverse flow.
Interface seals damaged by either of the
above. Replace damaged seals.
Control Box not
working Incorrect polarity on supply cable Reverse connections in supple cable
connection
