A high-quality 9R-8231 rectangular boom slide pad by VICORTEX. This is a wear pad made of durable polyamide material, used in the telescopic arms of older CAT backhoe loader series (e.g., 428B, 428C). It features dimensions of 200x110 mm, a thickness of 17 mm, and two mounting holes with an M12 thread spaced at 100 mm.
By choosing VICORTEX products, you rely on quality and reliability crucial for your machines. Created for demanding conditions, they offer excellent durability, minimizing failure risks and costly downtime.

| Caterpillar (CAT) | Backhoe Loaders | 416B, 416C, 420D, 424D, 426B, 426C, 428B, 428C, 428D, 430D, 432D, 436C, 438B, 438C, 446B, 446D |
The list above is for reference. It is crucial to verify the dimensions (200x110 mm, 100 mm spacing) on your machine.
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.
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.
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.
