Engine crank case cover plate

The GGT10 cover plate from O.S. Engine is a replacement assembly intended for crank case repair and servicing on model engines. It provides the external mounting and sealing face that keeps internal components aligned and enclosed.

Install this part when the original cover is damaged, excessively worn, or when crank case dismantling is required for maintenance. Supplied fully assembled to reduce bench time and simplify the swap process.

Fitting guidance: the component is designed to match the original mounting interfaces and offers the seating needed for typical gaskets or seals used in engine crank case service. Ensure mating surfaces are clean, flat, and that bolt holes are unobstructed before final assembly.

A reliable replacement cover plate for restoring crank case sealing and alignment during repair and tuning operations.

How do I measure to ensure this cover is compatible with my engine?

Measure the bolt hole spacing and the gasket face diameter on your existing cover and compare to the replacement. Exact match of hole positions is required for correct fitment.

Can I swap this cover between different O.S. engine models?

Interchangeability depends on the specific O.S. engine model. Confirm mounting pattern and sealing face dimensions before transferring the part between different engines.

Any tips for a smooth installation?

Clean mating faces thoroughly, fit fresh gaskets or seals, and tighten bolts in a cross pattern to the engine maker's recommended torque for an even seal.

What checks should I perform after installing the new cover?

After assembly, run a brief test at low load to confirm there are no leaks and that engine behaviour is consistent. Recheck torque and sealing if any anomalies are detected.
