O.S. Engine OS4A407010 Cover Plate for GGT10 crank case mounting part  [OS4A407010]

Cover plate for GGT10 engines

This cover plate is a direct accessory intended for RC-scale O.S. Engine GGT10 use, serving as a crank case closure and mounting interface. The description focuses on compatibility, installation considerations, and the role this part plays in engine tuning and service routines.

Compatibility: Designed for GGT10-series engines, the plate matches the case profile and mounting points used on that engine family. Before fitting, verify bolt pattern alignment and mating surface condition to ensure a correct seal.

Installation notes: Remove the engine from the model or secure it in a vise with soft jaws, clean mating faces, and check for old gasket material. Use the manufacturer's recommended torque values for case fasteners, tighten progressively in a cross pattern to avoid distortion, and inspect for any thread damage before final assembly.

Tuning and service role: While small, the cover plate contributes to case rigidity and proper alignment of internal components, which can affect compression and crankshaft stability. During routine maintenance the part is commonly examined for wear or damage that could lead to leaks or misalignment.
