TRACK TENSION ADJUSTMENT
Track must be tensioned enough to prevent de-tracking. Too much tension will cause increased wear on
roller, sprockets and drive motor bearings. There are two methods of measuring correct tension: Measure
the compression of the springs, or measure track sag.
To measure spring compression:
Loosen tension adjuster nut and lock nut completely. Measure free length of springs. Then tighten
adjuster nut to compress tension spring pair to a length of 5/8” (16mm) less than free length. Tighten lock
nut.
To measure track sag:
Lift the machine and raise the track off the ground. Measure the distance between either one of the central
rollers and track metal core bars and adjust track tension to get 1/2” (13mm) track sag.
To remove/replace track:
1.
Completely loosen tensioner nuts.
2.
Retract idler completely.
3.
Remove track from idler first, sprocket second and front roller last.
4.
Reverse procedure to replace track.
Adjust track tension per instructions and illustration.
