CYLINDER PERFORMANCE TESTS
NOTE:
All tes ts ar e performed with sta ndard boom, ar m and b ucket configuration. The bucket
should be empty.
BOOM CYLINDERS TEST
The starting points for the tes t a re wi th th e boom an d ar m extended away from the excavator, an d th e
bucket c urled in ward. T he ar m cylinder sh ould be ful ly r etracted; boom and b ucket c ylinders must be
extended. Test movement in both directions, several times, and average results for both Power Mode S and
Power Mode H.
ARM CYLINDER TEST
Start with the boom up and the arm cylinder fully retracted. Test movement in both directions several times,
between the “ crowd” a nd “ dump” pos itions, an d average the r esults o f bot h tes ts, i n bo th s tandard an d
extra-duty power modes.
Bucket Cylinder Test
Start with the b oom up a nd th e te eth o f the b ucket h anging vertically, 5 00 m m ( 1-1/2' to 2') ab ove th e
ground. Dump and crowd the bucket several times, and average results, for both standard and extra-duty
power modes
Measurement in Seconds
HYDRAULIC CYLINDER NATURAL DROP TEST
To check boom and arm cylinder tightness against the sp ecified performance standard for new cylinders,
put a full load of dirt in the bucket and move the attachment cylinders so that the arm cylinder is extended
20 mm to 50 mm (1" to 2") and boom cylinders are retracted the same amount, 20 mm to 50 mm (1" to 2").
The top of the bucket should be approximately 2 m (6' to 7') off the ground.
Turn off th e engine and measure cylinder drop after 5 mi nutes. Maximum cylinder dr ops are as follows:
boom and bucket 20 mm (0.787"); arm 40 mm (1.57"); and blade 10 mm (0.39").
