🔍 Key Concepts

• Study how the piston pin is held in place relative to the connecting rod in the left-hand section view. • Look closely at the area just below the piston crown for a possible heat dam (a groove or undercut used to reduce heat transfer to the ring belt). • Check whether the piston itself can rotate, or if a separate carrier/thrust washer or bushing is the rotating part on the pin.

💭 Think About

• On the illustration, does any bolt actually pass through or clamp directly to the piston pin, or is it securing another part that holds the pin? • Where is the groove or undercut located in relation to the top ring and piston crown, and what function would that shape serve? • Which component appears to be the one rotating on the pin: the piston, a carrier/boss around the pin, or the connecting rod small end?

✅ Before You Answer

• Verify whether the bolt shown at the small end is attached to the pin itself or only to a carrier yoke around it. • Confirm if the groove near the top land of the piston is separated from the ring belt, indicating a heat dam feature. • Determine if the piston skirt is keyed or fixed to any part that would prevent rotation, or if it appears free to turn relative to the carrier or thrust washer.
