⚠️ Safety Warning

Replacing stabilizer leg components requires the rear of the machine to be lifted and secured. Always use certified axle stands with an appropriate load capacity. Never rely solely on the machine's hydraulics. Use safety glasses and gloves.

Service Recommendation: Ensure Maximum Lifespan

For a complete joint 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

Thrust washers are sacrificial components designed to wear out to protect the much more expensive metal parts of the stabilizer leg. Ignoring worn pads leads to play, which causes the machine to "rock" during digging and can lead to damage to the stabilizer rams.

Replace the wear pads if you notice:

  • Excessive play (knocking) on the lowered stabilizer legs.
  • Inability to take up the play by adjusting the lower wear pads.
  • The machine is unstable and "rocks" when operating the backhoe arm.
  • Visible cracks or excessive wear of the old pads.

Peace of Mind Guarantee: Why Choose Our Offer?

An unstable machine means imprecise and unsafe work.

The cost of replacing a set of wear pads is negligible compared to the risk of damaging a ram or having an accident. Secure your machine – order a complete GX-AFTER set and work on a stable and secure foundation.

Expert's Guide: Key Installation Tips

  1. Check mating surfaces: Before installing new pads, thoroughly clean and inspect the stabilizer leg surfaces. If they are worn or have burrs, they should be ground smooth.
  2. Replace as a set: Always replace all wear pads on one stabilizer leg (lower and upper) at the same time to ensure parallel alignment and even load distribution.
  3. Choose the right thickness: We offer wear pads in different thicknesses (5mm, 6.4mm, 7.4mm) to compensate for the play created by the natural wear of metal components.
  4. Lubricate the surfaces: Before assembly, lubricate the sliding surfaces with a dedicated compound to ensure smooth operation.

Frequently Asked Questions (FAQ)

1. I have a lot of play on the leg, and the adjustable pads are fully tightened. What does that mean?

If play still exists despite the lower adjustable pads being fully tightened, it indicates that both the wear pads and the metal guides on the leg itself are excessively worn. In this case, in addition to replacing the pads, the leg itself may need to be rebuilt (by welding and machining) or replaced with a new one (part no. 128/G3070).

2. Do I have to replace the pads on both sides of the machine at the same time?

It is not absolutely necessary, but it is recommended. The legs wear out at a similar rate. Replacing the full set of pads on both sides ensures even stability and avoids a repeat repair in the short term.

3. What material are these pads made of?

They are made of a high-quality polymer with high abrasion resistance and a low coefficient of friction, often referred to colloquially as "Teflon," although technically it is most often polyamide or polyacetal.
