Track Adjustment
Caution! – Don’t loosen the valve body rapidly or excessively, otherwise the
grease in the tensioner will spray. Loosen the valve body carefully,
and don’t make the body and face against it.
– Don’t loosen the grease coupler.
– Important: if the crushed stones or soils are clipped between the
sprocket and track remove them after loosening the track.
– If the track is still too tight after tightening the valve body
anticlockwise, or it is still loose after applying the grease into the
grease coupler, this is abnormal.
– At this time, don’t try to remove the track or track-tension device,
because the high-pressure grease of track-tension device is
dangerous.
– Therefore, overhaul it or contact with your assigned dealer.
Notice! Adjust the sag of track.
– Points for attention for adjusting the track sag
– If the track sag is not within the desired range, loosen or tighten the track
as per the steps below.
– During the adjustment of track sag, lower the bucket to ground, and jack
the track on one side.
– Apply the same method to the track on the other side. Place the cushion
block under the frame every time to support the machine.
– After adjusting the track sag on both sides, move the machine forward
and backward several times.
– Check the sag of track again. If the track sag can’t reach the specified
value, continue to adjust it until it’s satisfactory.
– Loosen the track.
– In case of loosening the track, rotate the valve body
– slowly anticlockwise with a deep socket wrench, and the grease will be
drained out of its outlet.
– Rotate the valve body by 1 to 1.5 circles enough to loosen the track.
– If the grease can’t be smoothly drained, lift the track away from the
ground, and rotate the track slowly.
– After reaching the proper track sag, tighten the valve body clockwise.
– Tighten the track.
– If it’s necessary to tighten the track, connect the grease gun to grease
coupler, add in the grease until the track sag reaches the specified value.
