Times for Implement Drift for Boom, Stick, Bucket and the Bottom Dump
Note: The following values are for the maximum allowable drift with the oil temperature at 38°C (100°F).
Boom in RAISED Position
Start with the stick and boom cylinders at full extension. The allowable drift is 60.0 mm (2.36 inch) in 5 minutes.
Stick OUT
Start with the stick cylinders in the fully extended position for the front shovel. Start with the stick cylinders in the fully retracted position for the mass excavator. The following values are the maximum allowable drift in 5 minutes.
- Mass Excavator ... 60.0 mm (2.36 inch)
- Front Shovel ... 40.0 mm (1.58 inch)
Bucket in CURLED Position
Start with the bucket cylinders at full extension. The following values are the maximum allowable drift in 5 minutes.
- Mass Excavator and Front Shovel ... 50.0 mm (1.97 inch)
Bottom Dump in CLOSED Position
No specification is available.
Travel
The maximum drift in 100 m (328.1 ft) must not exceed 8 m (26.2 ft).
Times for Implement Drift at Other Oil Temperatures
Note: The minimum allowable time for the cylinder drift at other oil temperatures is specified in Illustration 1. The specified time is for the value of the drift which is given in "Times for Implement Drift for Boom, Stick And Bucket".
