13.5 Bale Restraint Beam Adjustment And Removal
To adjust the bale restraint beam(s) remove the two M12
bolts located in the holes on both sides of the restraint
beam, and loosen the third bolt in the slot. Reposition
the bale restraint beam by aligning the necessary holes,
replace and tighten bolts.
To remove, take the weight of the bale restraint beam
using a suitable lifting device. Remove the 3 bolts from
each end before extracting the bale restraint beam.
Refitting is the reverse of above.
13.6 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.
13.7 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 & 8550
Grade 8.8 Bolt M8 x 50 mm
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.
13.8 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).
13.9 Drive Chains
Apply chain lubricant or oil twice weekly to these chains.
13.9.1 Bed Chain Drive (7100 to 8550 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.
13.9.2 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.
