YSF4024 Piston Wrist Pin Compatible with DZ160 - YS Engine  [YSF4024]

Maintenance guidance for DZ160 wrist pin

The YS Engine wrist pin YSF4024 is supplied as a replacement component for DZ160 model glow engines, providing the crucial pivot link between piston and connecting rod. It is offered as a service item rather than a tuning upgrade and is recommended when the original part is worn or during scheduled engine servicing.

Operationally the wrist pin locates the piston on the small end of the connecting rod and must permit free pivot while keeping minimal play. Before fitting, confirm the wrist pin diameter and piston boss clearance on your DZ160, ensure circlips or retaining rings are fit for purpose, and remove any burrs to prevent scoring of mating parts.

Fitting notes: follow standard RC glow engine assembly practice, lightly lubricate the contact surfaces with appropriate engine oil, and rotate the assembly by hand to confirm smooth action and correct alignment prior to final reassembly. Correct fitment of this wear item helps maintain steady engine performance when tolerances are observed.
