⚠️ Safety Warning

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.

Service Recommendation: Ensure Maximum Lifespan

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.

Part's Role in the Machine and Failure Diagnostics

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:

  • Excessive play is found on the extended dipper arm, and the wear pads are new.
  • The old shims are cracked, deformed, or corroded.
  • There is uneven, jerky movement during extension and retraction.
  • Loss of precision when digging at full reach.

Peace of Mind Guarantee: Why Choose Our Offer?

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.

Expert's Guide: Key Installation Tips

  1. Check mating surfaces: Before installing new pads, thoroughly clean and inspect the arm surfaces. If they are worn or have burrs, they should be ground smooth.
  2. Replace as a set: Always replace all wear pads (lower and upper) along with the shims at the same time to ensure parallel alignment and even load distribution.
  3. Tighten evenly: Tighten the mounting bolts evenly to ensure proper pressure of the pad against the arm.
  4. Lubricate the surfaces: Before assembly, lubricate the sliding surfaces with a dedicated compound to ensure smooth operation of the entire mechanism.

Frequently Asked Questions (FAQ)

1. I have a lot of play on the extendadig. Will replacing just the wear pads be enough?

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.
