What is the purpose of a wrist pin bushing?

A wrist pin bushing, also known as a connecting rod bushing, sits between the piston pin (wrist pin) and the connecting rod. Its job is to create a smooth, low-friction surface for the pin to rotate within, allowing the piston to articulate freely as it moves up and down.

Why is proper clearance important for wrist pin bushings?

Correct clearance is vital for oil flow to lubricate the pin and bushing, and to prevent excessive wear. Too much clearance can lead to knocking noises and damage, while too little can cause binding and overheating.

Are these bushings sold individually or as a set?

The provided information indicates this is a single part number for a wrist pin bushing. Typically, these are sold individually, and you would need to order the quantity required for your specific engine build.
