13.5 Dual Chop Sieve Removal
Raise the blade beam and lock it in the upper position by
entering the bale chamber and sliding two bars through
the 19mm (¾”) diameter holes in the slides.
Remove the bale restraint beam as detailed above.
Remove the six M10 bolts that hold the sieve to the mid
body panels. Remove the six cup square bolts retaining
the screen to the support beam. The sieve can then be
removed by rolling it over the crossbeater.
Refitting is the reverse of the above.
13.6 Crossbeater Shear Bolts
To replace the shear bolt, open the left hand hinged drive
chain guard to gain access to the shear sprocket. Grease
the sprocket hub before replacing the shear bolt with a
shear bolt of the correct grade.
Feeder Bedders 7100, 8100, 8500, 9500 & 1010
Grade 10.9 Bolt M8 x 50 mm
Dual Chop Machines 7150, 8150 & 8555
Grade 8.8 Bolt M8 x 50 mm
NOTE: Under no circumstances should a higher grade or
larger diameter shear bolt be fitted. Should this happen,
damage to the gearbox could occur and warranty will
be invalidated.
13.7 Gearbox
Check the oil level in the rotor gearbox and bed chain
drive gearbox (where fitted) monthly.
After 50 hours of use the gearbox oil should be drained
and replaced with new oil. To drain the oil, remove any
guards, remove the drain and filler plugs and allow it to
empty. Waste oil should be collected and disposed of at
an oil recycling facility approved by the local authorities.
Refill the gearbox with SAE90.EP gearbox oil.
The oil capacity of the gearboxes:
Rotor gearbox 5 litres (1.3 US gallons).
Bed chain gear box 2.5 litres (0.55 US gallons).
13.8 Drive Chains
Apply chain lubricant or oil twice weekly to these chains.
13.8.1 Automatic lubricator
Where an automatic chain oiler is fitted, oil will be applied
to the chain and is controlled by a solenoid valve that
turns on when the bed chain is being operated. Rate of
oil application can be altered by turning the knurled knob
underneath the reservoir, to decrease application rate turn
in a clock wise direction.
Refill the reservoir with 2.0L of HVI 22 Anti Fling Oil.
13.8.2 Bed Chain Drive (7100 to 8555 models)
To tension the bed chain drive, remove the chain guard
on the right hand side of the machine, release the 2
clamp bolts on the motor mounting plate. Using the
tensioning bolt provided jack the motor mounting plate
until the chain has 12mm movement midway between the
sprockets, see Figure 12.
Figure 12. Chain tension.
13.8.3 Layshaft To Crossbeater Chain
To tension the layshaft to crossbeater chain drive, open
the hinged drive chain guard and loosen the four bolts
retaining the layshaft. Slacken the clamp bolt on the
layshaft universal joint. Slacken the M16 locking nut on
the tension bolt and tighten the tension bolt until the
deflection midway between the sprockets is correct, as
listed in Table 5. Tighten the tension bolt locking nut and
the four layshaft bearing retaining nuts. Tighten the
layshaft universal joint clamping nut and bolt before
finally closing the chain guard.
13.8.4 Lower To Upper Crossbeater Chain (9500 &
1010 models)
For the lower to upper crossbeater chain, open the
guard, slacken the tensioner roller mounting bolt in the
centre of the roller and turn the tension screw on the
adjuster clockwise until the deflection midway between
the sprockets is correct, as listed in Table 5. Retighten
the roller mounting bolt and close the guard.
Table 5. Chain Deflection.
13.9 Swivel Chute
The chute is rotated by means of a gear and ring gear. It
is important that this is well greased. To apply grease to
the ring gears there are 4 grease nipples on the mounting
flange.
The deflector ram has 2 grease nipples, one on each
pivot bush.
13.10 Hydraulics
CAUTION: Before attempting to dismantle any of
the hydraulic system, the tailgate and deflectors
must be fully lowered to prevent injury from the
unexpected lowering of these components.
13.10.1 Filtration
If the oil becomes contaminated then this can result in
failure of the hydraulic circuit. An inline pressure filter is
available if oil contamination is regularly happening.
