Zenoah K281742001 Crankshaft Assembly G450PU (W/O PACKING)  [K281742001]

Crankshaft assembly for G450PU

This Zenoah K281742001 crankshaft assembly is an RC-scale replacement part labeled for the G450PU engine family and supplied without retail packing. It serves as the rotating core inside the engine case and is used when restoring engine smoothness after wear or damage to the original crank. The listing identifies the part by model number and part name only, compatibility is drawn from the G450PU designation in the product title.

Installation involves standard engine disassembly and reassembly procedures for glow-style RC engines; during service check connecting rod alignment, bearing seats, and crankshaft end float before final assembly. The component's role in tuning is limited to restoring internal mechanical integrity rather than altering performance characteristics, so balance and bearing condition are primary inspection points after fitment.

When receiving this part verify the model number K281742001 matches your engine documentation and inspect for concentricity and visible damage before installation. If further confirmation of fitment is required consult the engine manufacturer or your parts supplier for cross-reference information.

This crankshaft is intended as a direct replacement component for G450PU-designated RC engines, intended for maintenance and rebuilds; confirm compatibility with your specific engine serials before proceeding.
