Measure cylinder bores

B01.40-0006-06

1 Cylinder liner

2 Dial gage

3 Gage for inside diameters

4 Outside micrometer

A, B Measuring direction in the cylinder liner

I Measuring point above the reversing point area of the first piston ring (wear-free area)

II Measuring point at the reversing point area of the first piston ring (highest wear area)

Check

1

Clean the cylinder liner (1) inside.

2

Check the cylinder liner running surface (1)

The running surfaces must not present signs of excessive wear and/or deformations.

Indications for checking cylinder liner damages caused by penetration of impurities

AH01.40-B-0001-01A

Measuring

3

With the micrometer (4), set the dial gage (2) and the inside diameter measuring gage (3) to the diameter of the cylinder liner (1)

Install the dial gage with 5 mm pre-load.

Outside micrometer

Gage for inside diameters

4

Measure the inside diameter of the cylinder liner (1) in the no-wear area (I) and set the dial gage scale (2) to “0”.

Measure at measuring point (I), above the reversing area of the first piston ring, in the directions (A) and (B).

*BE01.40-B-1001-03D

5

Measure the wear in the running surface of the cylinder liner (1), in the reversion area (II) of the first piston ring

Measure in the measuring point (II), area of highest wear, in the directions, longitudinal (A) and transversal (B).
