Note
Set the dial indicator in an upright position to the cylinder block.
Perform the measurement at 2 places for each cylinder as shown in the illustration, making a total of 8 measurements.
For the piston protrusion value of each cylinder, use the average of the 2 measurements of each cylinder.
| Protrusion |
|---|
| 0.005 to 0.255 mm(0.00020 to 0.01004 in.) |
Tech Tips
Measurement should be done at 2 locations, right and left sides of each piston head.
