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(s). Lower the tailgate to 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.
Single beater
shear bolt fails
repeatedly One or more bale restraint fingers bent
and interfering with crossbeater. Straighten or replace damaged bale restraint finger.
Twin beater
shear bolt fails
repeatedly Long dry material wrapping around
crossbeater(s) and bale restraint. Consult manufacturer.
Chute and rotor
blocks Chute exit blocked. Make sure material can leave the chute freely.
Rotor speed low. Check that slip clutch is not slipping
Select high rotor speed on gearbox
Swivel giraffe
chute blocks
Material not flowing smoothly. Raise deflector to improve flow and rotate chute to
achieve desired delivery position.
Rotor speed low. Check high rotor speed selected on gearbox.
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.
Bed chain no
longer operates
or only very
slowly. Failure
may be sudden
or intermittent. Dirt or contamination in the Bypass
Valve or the Pressure Relief Valve in the
flow control slice. Firstly, remove the Bypass Valve from the Flow
Control Slice inspect for contamination clean and
replace. If problem still exists, remove the Pressure
Relief Valve and inspect for contamination. If
problem persists or re occurs regularly replace tractor
hydraulic oil with new clean oil.
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.
Failure of pilot cartridge through
contamination
See section below.
Contact manufacturer for advice.
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 Oil leaking from
between slices
of the valve.
Clamping bolts loose. Check bolts through valve tightened to correct torque
specified in the maintenance section.
Interface seals damaged by either of the
above. Replace damaged seals.
