Other Measurements
a
Travel Linearity.
The conditions for checking are that the vehicle should
have an approach of 5 metres and a travel distance of
20 metres; measurement is of the amount of deviation
after 20 metres between the reference line and track
shoe.
Approach the reference line and adjust the position of
the track shoe/travel direction against the reference line
in the first 5 metres, then without adjusting, allow the
machine to travel 20 metres, then measure the
deviation, then complete the same procedure in
reverse.
b
Slew Backlash.
1
The conditions for checking are to position the
bucket in the open position slightly above ground
and to stop the engine.
2
Gently push the bucket from the side and put a
mark on the ground, this becomes the 'Zero
Point'.
3
Then do the same for the opposite side of the
bucket and make a mark, the distance the
bucket has moved is the amount of
backlash.
Note:
If the front attachment is pushed from side to side
repeatedly or if there is leakage or the attachments are
loose,
correct measurement will not be possible.
If the attachments are loose, position a dial gauge on the
turntable bearing and measure the movement here.
