BACKHOE BUCKET CROWD CYLINDER STRUT INSTALLATION
0021
The backhoe bucket crowd cylinder is deployed while traveling on the highway, to prevent the backhoe bucket from rolling
open.
WARNING
You could be killed or injured if the backhoe bucket drops while you are working near it. Install the
support strut as instructed below before traveling on the highway. Failure to follow this warning
may result in injury or death to personnel.
Keep people away from the machine while you fit or remove the strut. You or others could be killed
or injured if the loader is operated while you are close to it.
You may have to climb onto the machine to fit or remove the strut. Take care, especially if the
machine is wet. Remove mud and oil before climbing onto the machine. Never work on the
machine with a load on the forks/buckets. Failure to follow this warning may result in injury or
death to personnel.
NOTE
Before fitting the support strut, remove any load on the forks, and empty buckets or work tools.
1.
Install the boom lock before installing the crowd cylinder strut.
2.
Crowd the backhoe bucket sufficiently to be able to insert the strut (WP 0004).
3.
Ensure the parking brake is engaged and the transmission is in Neutral (WP 0004).
4.
Stop the engine (WP 0005).
5.
Remove the excavator bucket cylinder travel strut (Figure 5, Item 6) from its stowage position on the spare wheel carrier.
6.
Place the strut (Figure 5, Item 6) around the cylinder piston rod as shown. Fix it in place with clamp and latch (Figure 5,
Item 7).
7.
Thread cable thru loop (Figure 6, Item 8) and connect cable to connector (Figure 6, Item 9).
CAUTION
Dump the bucket carefully, to prevent possible damage to the strut. Stop as soon as the weight of
the bucket is on the strut. Failure to follow this caution may result in damage to equipment.
NOTE
Screw caps together.
8.
To prevent any chance of the strut (Figure 5, Item 6) becoming loose or creeping down, the bucket should be dumped to
trap the strut in position (WP 0004).
