Wheel Lift Cylinders and Wing Cylinders
There are no setup procedures or maintenance items on
these cylinders.
Disk Gang Disks
1. Replace the disk blades when the diameter is 17
inches or less.
It will also be necessary to check and tighten the disk
gang arbor bolts to prevent excessive wear.
After 12 hours initial operation, tighten the gang arbor
bolts to 600 to 800 ft-lb.
Note: A torque of 600 ft-lb would be equivalent to using
a 4 foot wrench with a 150 pound person hanging
freely on the end.
A torque of 800 ft-lb would be equivalent to a 200
pound person using a 4 foot wrench.
Note: When reassembling the disk gang, it may be
necessary to add a 1-3/8” machine washer
(FW-0138) in order to align the cross-drilled hole in
the shaft with the slots in the castle nut.
