Check the extendable stick for slop. Shim the extendable stick pads in order to maintain an acceptable fit and reduce slop.
Note: Do not apply an excessive amount of a silicone based lubricant. Dirt can be attracted to the lubricant and dirt can cause abrasion to the pad assemblies and wear to the pad assemblies.
The extendable stick pads do not normally require any lubrication. If the extendable stick becomes noisy, a small amount of a silicone based lubricant may be applied.
Adjustment for Top Upper Wear Pad
- Extend the extendable stick to one half of the fully extended position.
- Move the stick and move the boom down against the ground. This will take pressure off the wear pad.
Show/hide table
Illustration 2 g00635137 - Remove the bolts that secure the wear pad. Slide the pad toward the boom. There will be enough space in order to remove the pad. Either replace the wear pads or stack shims behind the pad.
- Shim the wear pad to
1 mm (0.04 inch) .
Note: In order to make adjustments to the remaining upper wear pads, refer to Disassembly and Assembly Manual, SENR1209, "Stick, Extendable Stick, Extendable Stick Cylinder".
- Extend the extendable stick out until there is enough clearance in order to remove the pads.
Show/hide table
Illustration 3 g00635788 - The side pads (1) can be shimmed without moving the stick or without moving the boom.
- Adjust the boom and adjust the stick in order to take pressure away from the top pad (2). Adjust the wear pads by shimming or replacing. Shim the wear pads to
1 mm (0.04 inch) . - Adjust the boom and adjust the stick in order to take the pressure away from the lower pad (3).
Note: Place the bucket on the ground. Apply slight pressure toward the ground with the stick. Shim the lower pad or replace the lower pad.
