Blade Carrier Removal
Cutter pans should be removed from top side by pounding on pan bar through the bolt access hole.
Blade Carrier Hub Installation
Clean the spines on both the blade carrier and output shaft. Position carrier on the gear box output shaft and
install flat washer and 1" hex nut. Tighten nut holding blade carrier to minimum 600 ft. lbs for the Wing Sections
and 450 ft. lbs for the Center Section, strike the carrier on the hub several times with a heavy hammer to seat
the hub. Use a suitable spacer over the nut to prevent damage to the nut and threads. Retighten the nut to 600
ft. lbs. for the Wing Sections and 450 ft. lbs. for the Center Section. Install and spread a new cotter pin when
retightening these nuts.
NOTE: Always recheck gearbox output shaft slotted blade carrier retaining nut torque after a few hours opera-
tion.
Avoid personal injury. Do not work under cutter without support blocks to keep frame from
falling.
SKID SHOES
Wing skid shoes are replaceable and should be checked and replaced as required.
SLIP CLUTCHES AND SHEAR BOLTS
Each of the three drive shafts running out of the divider box has both a slip clutch and shear bolt to protect it
from overload conditions.
Damp or wet conditions, and periods were the machine is not in use can cause the slip
clutch liners to bond to the slip clutch plates. As a result the shear bolts protection the
drivelines may break.
Shear Bolt breakage indicates that the Slip Clutch has seized. Always free up the slip clutch
when replacing a shear bolt or the driveline will be damaged.
Shear Bolts sizes are as follows:
Wing Shaft
M10 x 55 Metric
Center Shaft
M8 x 45 Metric
If the mower has been left unused for a period of time, e.g. a week, or in damp, wet
conditions, the clutch springs should be backed off. The mower should be run to ensure that
the clutches are slipping, then the springs should be tightened down to the heights indicated
in the following illustration.
As slip clutch liners become worn the clutch springs may have to be adjusted. By tightening or loosening the
bolt running through the clutch springs the releasing torque of the clutch can be set. If the bolt is set too tight
the slip clutch will not slip and damage to the universal joint shafts will occur. Setting the bolt to loose will cause
excessive slipping and the friction plates will wear out quickly.
Refer to the following illustration and set he height of the clutch springs as indicated. Tighten nuts following an
alternation cross pattern. Check that the height is constant for all springs. Mnt-R-0183
