tension cylinder until grease, free from air,
comes out of the grease plug. Securely
tighten the grease plug. Do not overtighten.
9 Continue to pump grease into the grease zerk
fitting just until the idler wheel moves. Check
the track tension.
10 If necessary, continue to pump grease into
the cylinder until the track has proper tension.
Component damage hazard.
Do not over tighten the track.
Over tightening the track will
cause the machine to lose
power during operation.
Note: If the track becomes too tight, loosen the
grease plug on the cylinder to remove grease and
loosen the track.
11 Clean up any grease that may have spilled.
12 Check the torque of the track assembly
fasteners. Refer to Specifications,

Manufacturer specifications require that this
procedure be performed every 50 hours.
Maintaining proper track tension and properly
torqued fasteners is essential to good machine
performance and service life. The machine will not
operate properly with a track that is incorrectly
tensioned. Continued use of a machine with
incorrectly tensioned tracks may cause component
damage.
1 Thoroughly clean the track assembly of any
dirt, rocks, clay, etc.
2 Chock the tracks at one end of the machine to
prevent the machine from rolling.
3 Center a lifting jack of ample capacity
(20,000 lbs / 10,000 kg) under the drive
chassis between the tracks at the other end of
the machine.
4 Lift the machine until the tracks are off the
ground and then place jack stands under the
drive chassis for support.
