Cover Plate Assembly GGT10 OS4A407000 for O.S. Engine Crank Cases  [OS4A407000]

Replacement cover for engine crank cases

The GGT10 cover plate from O.S. Engine is an aftermarket replacement part aimed at crank case repair and service tasks on model engines. It provides the external sealing face and mounting surface needed to enclose internal components and maintain alignment.

Use this cover when restoring a damaged face, renewing a worn assembly, or during maintenance that requires crank case access. Supplied as a complete cover plate unit to make part swaps quicker and reduce bench work.

Installation notes: the design follows original mounting interfaces and gives the necessary seating for common gaskets and seals used in RC engine crank case work. Ensure mating surfaces are clean and flat and that bolt holes are free of debris before final assembly.

A straightforward replacement to restore proper sealing and alignment on model engine crank cases during service and tuning.
