Related Parts and Hardware

To install this pad, you will need 2 bolts with M12 threads. We also recommend replacing other slide pads in the arm (often paired with smaller square pads 9R-8235) and using appropriate telescopic boom grease.

⚠️ Safety Warning

Operating with worn slide pads leads to excessive play in the telescopic arm. This causes imprecise bucket movements, jerking during extension, and in extreme cases, direct metal-on-metal contact between arm sections. This leads to irreversible and very costly damage to the machine's structure.

Part Role in the Machine and Failure Diagnostics

The 9R-8231 slide pad is a large, rectangular friction plate in the telescopic excavator arm. It allows smooth movement of the inner section relative to the outer section, absorbing the main pressure forces during operation.

  • › Excessive play (wobble) of the extended arm section.
  • › Loud grinding and squeaking when extending/retracting the telescope.
  • › Visible deep scratches on the inner arm section (sign of missing pad).
  • › Pad worn below safe thickness.

🔧 Expert Guide: Key Installation Tips

  1. Verify Dimensions: This is a large rectangular pad (200x110mm) with 100 mm hole spacing. Check if you don't need the smaller square version (9R-8235).
  2. Cleanliness: Thoroughly clean the arm of sand and old grease before installing new pads. Contamination drastically shortens their life.
  3. Play Adjustment: After installing new pads, it is necessary to adjust the telescopic arm play according to the service manual.
  4. Lubrication: Apply a suitable lubricant (often dry sprays or special pastes for telescopes) to ensure smooth movement.
