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 - CYLINDER BORE SPECIFICATION
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.
