Wrist pin for FZ110S - product notes

The YSF7329 wrist pin is supplied as a replacement part for the YS FZ110S engine family. It connects the piston to the small end of the connecting rod and is intended for use during model engine maintenance and rebuild procedures.

Prior to installation examine piston, rings, and rod for wear and ensure the pin is pressed in without canting to keep the piston concentric in the bore. Verify that circlips or equivalent retainers are seated correctly and use a light, glow-safe lubricant when breaking in the engine.

Replacing a worn wrist pin can help restore piston seating and ring seal, reducing unwanted play and aiding steady compression and running consistency without changing tuned settings.

Can I reuse the original circlips when fitting a new pin?

Reusing circlips is possible if they are undamaged and retain their spring tension, but best practice is to replace them to ensure positive retention and avoid failure during operation.

What technique reduces the risk of scoring during installation?

Use even pressure and a soft-jawed press or drift, support the piston correctly, and apply light lubrication. Avoid hammering directly on the pin or piston to prevent scuffing.

Is there any warranty or seller guarantee for this part?

Warranty terms depend on the vendor. Check the seller's product page for any guarantee or return policy details before purchase.
