Piston And Connecting Rod Inspection
- Check the oscillation torque as shown in the figure. Verify that the large end drops under its own weight with no resistance.
- If the piston shakes heavily or unsmoothly, disassemble the piston and connecting rod, then inspect the following: (See
PISTON PIN INSPECTION .)
- Clearance between piston pin outer diameter and piston pin hole diameter.
- Clearance between piston pin outer diameter and connecting rod small end inner diameter.
