O.S. Engine Connecting Rod Plate OS4A407020 GGT10 Replacement for RC Engines  [OS4A407020]

Replacement connecting rod plate for O.S. engines

This O.S. Engine OS4A407020 connecting rod plate GGT10 is an internal service component for O.S. model engines, designed to replace the connecting assembly plate during engine rebuilds or when restoring correct clearance between the crank and rod.

When fitting this plate treat it as an internal engine service task: remove the engine from the model, disassemble the crankcase per the engine manual, inspect mating faces and bearings, position the plate in the correct orientation and apply the specified torque values, then confirm free rotation before completing reassembly. Use recommended threadlocker and clean lubricant where the engine documentation specifies.

As a maintenance item the connecting rod plate supports proper rod alignment and oiling passages; while not a primary tuning component, it contributes to smooth running and reliable operation. Check the plate and its mating surfaces when investigating vibration or internal noise as part of routine fault finding.

Keep spare plates on hand for scheduled overhauls and replace the component if wear or distortion is found to preserve engine longevity in scale RC applications.
