Highlights

NRP aftermarket top roller CA423 replaces a worn upper carrier roller on compatible Case crawler undercarriages. Positioned above the track frame, it supports the returning track chain and helps keep it on its running path during travel and grading. Each price covers one top roller.

Key Features
  • Upper Track Support — Supports the return run of the track chain above the track frame.
  • Track Guidance — Helps keep the returning chain aligned as it travels between the sprocket and idler.
  • Replacement Reference — Uses CA423, cross-referenced to Case R33594, for the listed mounting applications.

Key Features

Direct Replacement: Replacement top carrier roller using part number CA423 for compatible Case equipment.

Upper Track Return: Supports upper track return and helps guide carrier roller movement on compatible crawler dozer undercarriages.

Case 1150 Dozer Fitment: Designed for listed Case 1150 crawler dozer carrier roller applications.

Smooth Roller Operation: Supports smooth rotation to help reduce vibration, noise, and unnecessary track wear.

Part Number & Fitment Check: Part number CA423 can be used to confirm compatibility. Verify your machine model and existing top carrier roller before ordering.
