Description

Caterpillar 303 CR Pin and Bushing Kit – Repair Kits by Position and Series

The Caterpillar 303 CR pin and bushing kit is a position-specific repair kit for various bearing and cylinder points on your machine's boom, lift arm, dipper stick, bucket, and linkage.

The kits differ according to position number and series (DMA 0001–0496, DMA 0497 and higher, MY3). In some cases, the contents are identical, while in others, the number of bushings, seals, or pins differs significantly.

Important: Please check the position number and series of your machine against the type plate or spare parts drawing before ordering.

Advantages of the Repair Kits

  • Perfect fit for Caterpillar 303 CR
  • Position-specific replacement instead of complete overhaul
