O.S. Engine OS28162000 Crankshaft for GT15 Engines  [OS28162000]

GT15 Crankshaft Technical Summary

This crankshaft is a replacement component for the GT15 line by O.S. Engine and is identified by model number OS28162000. It functions as the rotating assembly core inside compatible GT15 engine variants and is intended for maintenance, repair, and rebuild tasks on model engines.

The description focuses on practical fit and function rather than marketing language: the crankshaft is intended to fit GT15-series engines used in radio-controlled applications and is aimed at hobbyists with experience in engine disassembly and reassembly. No road-vehicle application is implied.

Installation notes and tuning role: fitting this crankshaft normally requires a full engine teardown to access the crankcase, inspection of bearings, and correct endplay adjustment. As the primary rotating part it influences balance and smoothness, and is relevant when addressing wear-related vibration or restoring engine geometry in RC engines.

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