O.S. Engine OS4A402000 Crankshaft GGT10 Engine Crank Shaft Part  [OS4A402000]

GGT10 Crankshaft for RC Engines

This crankshaft is an RC-scale replacement part listed as O.S. ENGINES CRANKSHAFT GGT10 and identified by model number OS4A402000. It is intended for use with engines designated under the GGT10 name, serving the core role of converting piston motion to rotational output within glow RC engines.

In service, the crankshaft affects rotational balance and interacts directly with the crankcase, bearings, connecting rod and flywheel; when replacing this part, inspect mating surfaces and走珠軸承 for wear, verify axial and radial fits, and confirm endplay and sealing surfaces before final assembly. This description assumes the part will be used on RC engines only.

Use this crankshaft as a direct service replacement when restoring engine rotation quality or after bearing and crankcase work, and always verify fit and clearances against the specific GGT10 engine assembly prior to running.
