Item #16 of the piston shown in the illustration is a/an __________. MO-0011

Correct Answer: Option D — thrust plate or thrust washer

Thrust plates or thrust washers absorb axial forces and maintain proper side-to-side clearance within articulated or carrier-type piston assemblies. Item 16 specifically points to this bearing surface, which manages lateral thrust loads generated by connecting rod angularity during engine operation.
