DZ160 Piston Wrist Pin - Precision Fit YSF4024 by YS Engine  [YSF4024]

DZ160 wrist pin specification

This YS Engine wrist pin, model YSF4024, is a replacement component for DZ160 glow engines that forms the mechanical link between piston and connecting rod. It is supplied as a direct replacement rather than a performance upgrade and is ideal when the factory pin shows wear or when you are performing routine engine rebuilds.

The wrist pin locates the piston on the small end of the connecting rod and should operate with minimal play while allowing free pivoting. Before fitting, verify the pin diameter and piston boss clearance on your DZ160, inspect retaining clips or circlips for proper seating, and remove any burrs to prevent scoring the piston or rod.

Installation notes: follow accepted RC glow engine assembly practice, apply light lubrication with a suitable engine oil to contact surfaces, and rotate the assembly by hand to confirm smooth movement and correct alignment before completing reassembly. As a wearable spare, the wrist pin helps maintain dependable engine operation when matched to correct tolerances.
