Piston And Cylinder Bore, Checking: Notes
WARNING: This page is about a different variant/trim than selected.
-- Measure approximately 15 mm from the lower edge at a 90° angle to the piston pin axis using a 75 to 100 mm external micrometer.
- Maximum variance from the specified size: 0.04 mm.
NOTE:
Check for wear on the piston shaft-coating and general coking.
The piston must be replaced if cracks have formed on the piston shaft.
| Piston Diameter In mm | |
|---|---|
| Specified size | 80.92 1) |
|
|
-- Using a :VAS6078 measure in a diagonal sequence at three positions laterally -A- and longitudinally -B-.
- Maximum deviation from the nominal dimension: 0.10 mm.
NOTE:
Pay attention to scratches and other abnormalities on the cylinder wall.
| Cylinder Bore Diameter In mm | |
|---|---|
| Specified size | 81.03 |
NOTE:
The cylinder bore must not be measured when the cylinder block is mounted on the :VAS6095A because the measurements may be incorrect.
