O.S. Engine OS28162000 Crankshaft GT15, crankshaft for GT15 RC engine  [OS28162000]

GT15 crankshaft overview

This crankshaft is an RC-scale replacement part labelled for the GT15 line from O.S. Engine and identified by model number OS28162000. The piece functions as the rotating assembly core inside compatible GT15 engine variants and is intended for model engine maintenance, repair, and rebuild tasks.

The article focuses on technical clarity rather than marketing claims: the crankshaft is described as a part designed to fit GT15-series engines, used within radio-controlled model applications, and intended to be installed by hobbyists familiar with engine disassembly and reassembly. No road-vehicle use is implied.

Installation considerations and tuning role: fitting this crankshaft typically requires full engine teardown to access the crankcase, careful bearing inspection, and correct endplay adjustment. As a rotating component, it affects balance and smoothness of engine operation so it is relevant when restoring engine geometry or addressing wear-related vibration in RC engines.

Use this crankshaft when replacing a worn or damaged rotating assembly in GT15-series RC engines, and follow manufacturer service procedures for bearing replacement, seal seating, and torque specifications during reassembly.
