  1. Compare measured pin OD and small-end ID (or specified clearance checks) with the workshop manual limits
  2. Judge clearance only by how quietly the engine idles after assembly
  3. Use a tyre pressure gauge reading as a substitute for pin measurements
  4. Skip measurement if the piston pin slides in by hand with no comparison to limits
