CR-01 One-Piece Rear Hub Technical Upgrade - TAMIYA CR01-19/LB by 3Racing  [CR01-19/LB]

Technical overview

This one-piece rear hub is presented as a precision replacement for CR-01 chassis applications where a single-unit hub simplifies reassembly and reduces variables in rear axle mounting. It is intended to provide a consistent mounting surface for rear wheels and associated driveline components on scale crawlers and trail trucks.

Compatibility is confined to CR-01 platforms that share the stock rear hub mounting and axle layout. Prior to installation, verify axle diameter, hex engagement, and set-screw locations against the hub to ensure correct mechanical interface and preload conditions.

Service and install notes: remove the rear wheel and hub assembly, extract the existing hub from the axle, and inspect axle journals and mating faces for scoring or deformation. Align the replacement hub on the axle hex, secure using the appropriate hex fasteners, and torque to the CR-01 chassis specified values. Apply thread locker selectively when reusing metal screws for sustained off-road operation.

A technically focused replacement hub for CR-01 models to maintain consistent rear mounting and simplify axle service procedures; validate fitment and follow chassis torque data for reliable operation.
