Precision piston pin for GT22 power units

The O.S. Engine OS28206000 piston pin is a precision replacement component for GT22-series nitro engine assemblies. Acting as the wrist pin between piston and connecting rod, it is supplied as a service part for regular maintenance and measured tuning work typical of fuel-powered RC models.

Installation notes: examine the piston boss and small-end bearing or bushing for wear prior to installation, press the pin in with correct alignment, and verify unobstructed piston movement within the cylinder before completing the rebuild. Use a light lubricant compatible with nitro engines to prevent scoring during the initial starts.

Compatibility and performance: fitting a new piston pin reduces lateral piston play and can prevent scoring of the cylinder wall, maintaining compression and consistent operation through heat cycles. When replacing the pin, also inspect piston rings, small-end components, and connecting rod play to support dependable engine performance.

How do I verify OS28206000 is correct for my GT22?

Confirm your engine is a GT22 and cross-check the OS28206000 part number with the official parts diagram or supplier reference to ensure the pin matches your engine configuration.

Which checks are recommended when fitting the pin?

Inspect mating surfaces, ensure the small-end fits the connecting rod, apply a light nitro-safe lubricant, and confirm the piston moves freely before final assembly to avoid binding.

Should I replace other components at the same time?

It is advisable to check piston rings, small-end bearings or bushings, and connecting rod integrity while the engine is open to prevent repeat disassembly and ensure reliable running.
