Zenoah K281742001 Crankshaft Assembly for G450PU (No Packing)  [K281742001]

G450PU crankshaft replacement unit

The Zenoah K281742001 crankshaft assembly is presented as a replacement component for engines bearing the G450PU designation and is delivered without consumer packaging. It serves as the central rotating assembly inside the crankcase and is typically fitted when the original crank shows wear or mechanical damage. Compatibility is drawn from the G450PU label in the product title and the model number is provided for confirmation.

Fitting requires standard engine service procedures for glow-type RC motors; during rebuild check connecting rod seating, bearing fit, and crankshaft end float before final assembly. This part's primary purpose is to restore internal mechanical function rather than provide tuning gains, so ensure bearings and balance meet service limits after installation.

When you receive the part, confirm the stamped or listed model K281742001 matches your replacement requirement and inspect for runout and surface damage prior to installation. If you need fitment verification, contact the engine manufacturer or your spare parts supplier for advice.

Intended as a direct replacement for G450PU-specified engines to assist with maintenance and rebuilds; always double-check compatibility with your specific engine serials prior to fitting.
