Pic. 2.115. Measuring the inner diameter of the bushing of the upper head of the connecting rod
Using a dial gauge, measure the inside diameter of the connecting rod bushing (pic. 2.115).
- The standard diameter is 22.005–22.017 mm.
- The limiting diameter is 22.017 mm.
Calculate the clearance between the piston pin and bushing.
- The standard clearance is 0.005–0.011 mm.
- Limit clearance - 0.05 mm.
If the clearance is greater than the maximum, replace the bushing. Replace piston and piston pin assembly if necessary.
