CUTTER DRIVE BELT ADJUSTMENT.
The Cutter Drive is via a single 3V Belt.
The belt tension should be set to allow ¼ to 3/8 inch
deflection at a point midway between the Drive Motor and
Crankshaft Sheaves.
To adjust the tension:
• Loosen Drive Motor Mounting Bolt Locknuts ‘A’.
• Turn the Adjusting Nut ‘B’, ‘clockwise’ to in-
crease the belt tension.
• Turn the Adjusting Nut ‘B’, ‘counterclockwise’ to
decrease the belt tension.
• Tighten the Motor Mounting Bolt Locknuts.
CUTTER DRIVE BELT - REPLACEMENT.
• Remove the Cover Plate, on the opposite side to
the Drive Motor.
• Slacken the Drive Belt, (see above), and remove
the belt from the motor and crankshaft sheaves.
• Remove the R.H. Connecting Rod Cap ‘C’.
• To prevent the L.H. Connecting Rod from
‘bending’ when the Crankshaft Pillow Block
Bearing is pried ‘down’, loosen the Connecting
Rod Cap.
• Remove the Bolts ‘D’, from the Crankshaft Pillow
Block Bearing.
• Pry the Bearing ‘down’, away from the frame,
sufficient to allow the belt to be removed.
• Re-assemble in the reverse order. Check that the
Crankshaft is ‘square ‘ to the frame when
tightening the bearing bolts.
IMPORTANT
If there are Shims between the Crankshaft Bearing
and the Frame, ensure that they are in place when re-
assembling.
CONVEYOR MATS.
Rubber Mats are suitable for most conditions, and are the
preferred type. The Mintex Metal Mat is used in loose
‘stoney’ soil conditions.
The Rubber Mat is kept in alignment in the frame with the
Drive Sprockets at the top of the conveyor, and a Crown
Roller at the bottom of the conveyor. The Mintex Mat runs
on Sprockets, top and bottom. The Alignment procedure
is the same for both mats.
DRIVE SPROCKET SHAFT.
The L.H. Side Sprocket Shaft Bearing is adjustable to
ensure that the Shaft is at 90 deg. to the Frame, and the
mat is correctly aligned at the top of the conveyor.
• Loosen the Bearing Bolts ‘E’, until they are ‘snug’.
• Back-off the Locknut ‘F’, and turn the Adjusting
Bolt ‘G’, ‘IN’ to push the Bearing to the rear, or
tap the Bearing ‘forward’, as required to correctly
align the Sprocket Shaft.
