Alltech KEENAN MechFiber340 - Wheel and Elevator Maintenance; Annual Wheel Hub Maintenance; Rear Feedout Elevator Maintenance

Revision G04 July 2018
8.9 WHEELS
1. Each year lever o the hub cap, remove the split pin and castle nut and
remove the hub.
2. Check seals, bearings, brake shoes, springs, studs, and all other
internal parts.
3. Replace worn parts, re-grease and ret.
Note:
When re-tting the wheels, tighten the castle nut until resistance is felt (do not
over tighten). Release the castle nut 1/6 of a revolution, check for movement in
the hub, and if none, re-t the split pin.
At the end of the feeding season wash the machine down thoroughly preferably
using a power washer. Grease or oil all lubrication points and open the drain
bung on the bottom of the machine.
Changing a wheel
• Park the mixer wagon on level ground and apply the handbrake.
• Fit chocks to opposite wheels to prevent machine movement during the
operation. Loosen the wheel nuts with a wrench but do not remove the nuts at
this stage.
• Jack up the mixer wagon underneath the axle until the bottom of the wheel is
o the ground. Remove the nuts completely and slide o the wheel.
• Ret the wheel ensuring that the centre of the wheel is properly located on the
hub and hand tighten wheel nuts.
• Lower the machine and tighten the nuts to the recommended torque using
suitable equipment.
• Check the wheel nuts for tightness after 1 hour of use, repeating on a weekly
basis.
8.10 REAR FEEDOUT ELEVATOR (WHERE FITTED)
An elevator system requires regular maintenance in order to achieve optimum
performance. Every week the elevator needs to be checked to make sure that
the belt is running straight and not wearing unevenly on one side. If the belt is
not running straight then adjust the tension by adjusting the tensioner nut on
the side and run again to check.
The elevator surface needs to be kept clean at all times in order to avoid feed
building up and falling into the rollers during operation. Do not allow old feed to
build up on the sides of the belt.
Each week ensure that the bearings are greased as per gure 18 below. Ensure
that the elevator is free moving in each direction and there is no feed caught
in the slideways. Replace belts and side rubbers when they become worn
otherwise elevator will not function properly. Refer to the Rear Feedout Operator
Manual Supplement for spare parts, maintenance and operation.
