Adaptor Fixing Screw CSM3X8 - O.S. Engine OS22826131  [OS22826131]

Engine Adaptor Fixing Screw Details

The O.S. Engine OS22826131 adaptor fixing screw is intended as a replacement fastener for securing adaptor assemblies on model engines. The CSM3X8 identifier in the product name specifies the screw form commonly used with adaptor flanges and couplings.

This part may seem minor, but it is necessary when rebuilding or servicing adaptor interfaces to maintain alignment between the adaptor and the engine output. It is used wherever the original hardware calls for a CSM3X8 fixing screw.

Prior to completing installation, verify thread engagement and seating depth for your particular adaptor and crankcase to prevent interference. Routine checks during engine maintenance help catch loose hardware and ensure steady adaptor alignment under operation.
