Blade Carrier Removal; Blade Carrier Installation - Schulte FX-1800 Operator's Manual

BLADE CARRIER REMOVAL

Remove cotter pin and loosen slotted nut on gear box shaft. Loosen but do not remove the nut until the blade
carrier is loosened. Use a suitable two-jaw gear puller to pull carrier off tapered gear box shaft. If gear puller is
not available use long bar inserted through blade bolt access hole with end against rotor bar. Strike opposite
end of bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process.

Blade Carrier Installation

Clean the taper and splines on both the blade
carrier and output shaft. Castle nuts and cotter
pins are used to tighten the cutter pans to the
splined shaft on the cutter gearboxes. A cone
washer is used between the nut and the gearbox
main shaft. The washer must cone down towards
the nut. A flat washer may be required if the hole
on the shaft and the slots on the castle nut do not
line up.
The slots on the underside of the blade carrier
must line up with the hole on the gearbox shaft so
the cotter key can be inserted. To aid in alignment,
mark a line on the bottom of the gearbox shaft,
parallel with the cotter key hole.
Rotate the blade carrier until the slots are parallel
to the mark. The pan may need to be spun 180° so
the splines match.
A 2-1/16" socket can be used to torque the M36
nut to 600 ft-lbs(814 Nm) dry assembly. 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(814 Nm)
dry assembly. Install new cotter pins when
retightening these nuts.
It is important that the retaining nut be checked
after a few hours of operation then periodically.
Retightened if necessary.
AVOID PERSONAL INJURY. DO NOT work under cutter without support blocks to keep
the frame from falling. Mnt-R-0006
