REP-TAT-P-1111-13 Measuring all cylinders
NOTE:
The description is for one component only. The procedure is identical for all further components.
Measuring a cylinder
Prerequisite
Cylinder path is cleaned.
Check
- Adjusting measuring screw to nominal dimension of cylinder bore.
TECHNICAL DATA SPECIFICATIONS
| Cylinder bore | ||
| Diameter of cylinder bore | 82.007 mm... 82.014 mm | |
| Permitted irregularity of the cylinder bore | 0.01 mm | |
| Permitted conicity of the cylinder bore | 0.01 mm | |
| Permissible total wear tolerance between piston and cylinder bore (engine operated) | 0.15 mm | |
- Insert internal measuring device into measuring screw and set to zero.
- With the internal measuring device, measure the cylinder at the following points and check the deviations from the nominal dimension.
- Lower third of the cylinder bore in direction of travel,
- Lower third of the cylinder bore transversely to direction of travel,
- Middle third of the cylinder bore in direction of travel,
- Middle third of the cylinder bore transversely to direction of travel,
- Upper third of the cylinder bore in direction of travel,
- Upper third of the cylinder bore transversely to direction of travel.
