O.S. Engine OS44907000 Replacement Cover Plate for FSa-110  [OS44907000]

Overview: FSa-110 Cover Plate

The O.S. Engine OS44907000 cover plate provides a straightforward RC crank case replacement for the FSa-110 designation noted in the product title. It is intended purely as a service and sealing component to restore case integrity on compatible O.S. engines without claiming performance changes.

To install, access the crank case by removing the mounting hardware or cooling head if required, keep original fasteners and alignment dowels in place, line up the plate with existing openings, and secure it using the engine’s screw pattern. Use basic hand tools and moderate torque settings to prevent damage to the case threads.

As part of routine maintenance, the plate allows inspection and replacement of internal parts while preserving the intended internal alignment and timing geometry. Use this cover when carrying out leak checks, part changes, or scheduled service to maintain consistent engine assembly condition.
