2

Mark the cylinder liner (1) to be removed in relation to the engine block.

3

Install the cylinder liner removal device (6) and remove the cylinder liner (1).

4

Remove the metal ring (3).

In the case of removing several cylinder liners and there are shims under the metal sealing rings, it is convenient to pay attention on the shim thickness of each cylinder. At assembly, install shims with respective corresponding measurement in each cylinder.

5

Remove the top sealing ring (2) and the sealing rings (5).

6

Clean the cylinder liner (1), specially the cylinder liner collar and the housing of the rings (2, 3 and 5).

Check

7

Check the cylinder liner (1) for cavitation and corrosion.

Cavitation: Is a form of erosion that may eventually arise in the cooling pressure line affecting the cylinder liner forming cavities. Cavitation is produced by the coolant in motion that forms steam bubbles. The oxygen contained inside these bubbles added to the continuous shock, corrodes the cylinder liner metal. The electrolytic process also contributes to aggravate the problem.

The following preventive measures inhibit cavitation: a - The use of coolant composed and prepared with specific products and in the correct mix proportion recommended by the manufacturer. b - The periodic control of the coolant's density to evaluate its concentration. c - The constant replenishment of consumed coolant utilizing the appropriate coolant and prepared in advance. d - Changing the coolant in the recommended periods. e - To maintain the engine temperature within the recommended operating range. f - To maintain the cooling system in perfect conditions and utilizing caps, hoses and other components in perfect conditions.

Corrosion is the oxidization formed around the cylinder liner in all its cooling area reached by the circulating coolant. Oxidization is caused by the prolonged contact with the coolant (not within specification) and may occur in the following circumstances: a - Lack of recommended additives in the preparation of the coolant. b - Incorrect proportion of the mix utilized in the constant replenishing.

Installing

20

Install in the housings of the engine block (4) the two bottom rings (5) dry and clean.

21

Install the metal ring (3) in the block (4).

*BE01.40-B-1015-03B

In the case there is a shim under the metal ring (3), install it in the housing of the cylinder liner collar in the block and next install the metal ring (3) (utilized in exceptional cases, in the case of having machined the housing of the cylinder liner collar).

*BE01.40-B-1016-03B

22

Install the dry and clean top ring (2) in the cylinder liner.

23

Install the cylinder liner (1) in the engine block (4).

Apply a film of engine oil around the cylinder liner (1).

If the cylinder liner is a new one, preferably install it in the block with the letter B-C-D or E (corresponding to the size) positioned to the engine front. This will be a reference to turn the cylinder liner 90 degrees in a future removal.

AR03.10-B-7021-02A

If the cylinder liner is used one, install it in the block offset 90 degrees from the original position.

24

Install the assembly device in the cylinder liner (7) and insert it in the cylinder.

25

Measure the cylinder liner (1) protrusion in the block (4).

AR01.40-B-9314A

26

Measure the cylinder liner (1) inside diameter (in the area of the sealing rings) in three points separated 60 degrees from each other.

In the case of an out-of-round above the specified values, remove the cylinder liners and check the rings.
