YS Engine YSF4024 Piston Wrist Pin for DZ160 RC Engine  [YSF4024]

Piston wrist pin for DZ160

This YS Engine wrist pin is an RC-scale replacement part intended for DZ160 model glow engines, serving as the mechanical link between piston and connecting rod. It is presented as a direct replacement component rather than a performance upgrade, useful when the original wrist pin shows wear or during routine engine rebuilds.

Functionally, the wrist pin locates the piston on the small end of the connecting rod and must run with minimal play while allowing free pivoting. When replacing, confirm the pin diameter and piston boss clearance on your DZ160 assembly, inspect retaining clips or circlips for secure seating, and remove any burrs before installation to avoid scoring the piston or rod.

Installation notes: use appropriate RC glow engine assembly practice, light lubrication with a suitable engine oil on fit surfaces, and rotate the assembly by hand to verify smooth movement and correct alignment before full reassembly. As a wearable spare part, the wrist pin supports reliable engine operation when matched to correct fit tolerances.
