G450PU Replacement Crankshaft Assembly K281742001 - Zenoah  [K281742001]

Replacement crank for G450PU engines

This Zenoah K281742001 crankshaft assembly is an RC-scale replacement part identified for the G450PU engine family and shipped without retail packing. It functions as the rotating core inside the engine case and is used when restoring smooth operation after wear or damage to an existing crank. The listing identifies the unit by its model number and G450PU designation for compatibility reference.

Installation follows standard disassembly and reassembly steps for glow-style RC powerplants; during service check connecting rod alignment, bearing seating, and crankshaft end float prior to final assembly. This component is intended to restore mechanical integrity rather than change tuning characteristics, so bearing condition and balance are the primary post-fitment checks.

On receipt confirm the model number K281742001 matches your engine records and inspect the crank for concentricity and visible damage before installation. For cross-reference information or fitment confirmation contact the engine maker or your parts supplier.

This crankshaft is supplied as a replacement for G450PU-designated RC engines for maintenance and rebuild work; confirm compatibility with your specific engine serials before proceeding.
