A precision-made adjustment shim, a key component of the telescopic backhoe arm system. It is installed under the lower extendadig wear pads. Its function is to take up play and correctly position the lower wear pads on which the extending section slides. Made of durable steel, it ensures proper support for the pads and smooth operation of the telescopic boom. 4 pieces are used per machine.

Replacing backhoe arm components requires the arm to be immobilized and secured. Always use the service lock and certified axle stands. Never rely solely on the machine's hydraulics. Use safety glasses and gloves.
For a complete refurbishment, always replace the upper and lower wear pads at the same time. To ensure perfect sliding and corrosion protection, coat the wear surfaces with a dedicated lubricant like HYPTRON - Wax Grease SHIELD. Remember to also regularly grease the pins and bushings with HYPTRON grease with MoS2 additive.
Adjustment shims are crucial for correctly setting the clearances on the telescopic boom. Worn or cracked shims cause the wear pads to not sit correctly against the arm, leading to play, jerky extension, and can result in damage to the extender ram.
Replace the shims if:
An unstable telescopic boom means imprecise and unsafe work.
The cost of replacing a set of wear pads is negligible compared to the risk of damaging the extender ram or the arm itself. Secure your machine – order a complete GX-AFTER set and restore the factory rigidity and smoothness to your telescopic arm.
Not always. The play on the telescopic boom is controlled by the entire system of wear pads and shims. Replacing only one type of component will not yield the desired result and will cause accelerated wear of the new parts. A complete set should always be replaced.
2. What should I use to lubricate the extendadig slides?For this type of sliding friction, it's best to use specialized products like a wax-based grease (e.g., HYPTRON - Wax Grease SHIELD), which creates a durable, dry lubricating film that does not attract dirt and dust.
3. What material are these shims made of?They are made of high-quality steel, resistant to deformation and abrasion.
