What is the purpose of a wrist pin bushing?

A wrist pin bushing sits in the small end of the connecting rod. It creates a precise, low-friction interface for the piston's wrist pin, allowing the piston to pivot smoothly as the engine runs.

Why is proper fitment of the wrist pin bushing important?

Correct clearance is vital. Too much play can lead to knocking noises and accelerated wear on both the bushing and the wrist pin. Too little can cause binding and premature failure.

Does this bushing come with a wrist pin?

No, this part is just the bushing itself. The wrist pin and connecting rod are separate components and are not included with this part number.
