Cylinder Liner

Wet cylinder liner, is a changeable part which is a made from alloyed cast iron and it is inserted by sliding inside the cylinder block. Cooking liquid existed in the compartment of the cylinder block, surrounds the cylinder liner and cools is directly, and eventually it leads to the adjustment of the motor temperature.

Instruction of installment of cylinder liner

The method of repair or replacement of the cylinder liner

In case of the following defects the cylinder liner should be changed, otherwise it is repairable and correctable.

1) if the internal diameter with its geometric tolerances are out of range

2) cracking of liner edge

3) damage of the rubber grooves around the liner

4) the existence of corrosion or holes on the liner

5) the existence of crack or fracture on the liner

6) Existing the depth lines on the internal surface of the liner

Pulling out the cylinder liner

When taking out the cylinder liner a correct and suitable method should be used otherwise cylinder liner and block will be damaged.

1- pull out the piston and piston handle as in the time of assembly.

2- If reusing the busing is possible, make the place of cylinder block on which liner is placed.

3- Release the hoof of the tools taking out the liner

4- Place the hoof on the lower edge of cylinder liner

5- Rewind the screw on the tools in clock wise direction to remove the cylinder liner

6- Take out the sealing O rings around and below the edge of liner and dispose them

7- Remove the pulling tools from cylinder liner

Note: cylinder liner should be kept in an upright position. Cylinder liner which are laid on the side for a long time may run out and deformed so their installation on the motor not possible.

 

Cleaning the cylinder liner

Note: if the liners are not going to be installed for sometime, clean them gently with protective oil and store them in a clean and dry place in an upright position.

1) wash the new and used liners with a storage washer and warm water or steam and clean them with a non- metal haired brush

2) dry liner by the pneumatic pressure

3) cover the internal surface of the liner with a fresh motor oil

4) clean inside the liner by a clean cloth

5) if some dark spots are still seen on the cloth, repeats the steps 4-6 until no spot is seen on the cloth.

Controlling Cylinder Liner

1- Control cylinder liner for existing any crack, stroke or... and in case of observing any damage change it.

2- Control cylinder liner for surface cavity corrosions (in the used liner) and in the case of existing any hole change it.

3- Examine and control the edge of liner for cracking or stroking (especially in the used liners).

4- Control and check the sealing grooves (O ring) for stroke and damage.

5- Measure the external diameter of the liner.

6- Measure exactly the internal diameter of the liner in terms of the geometrical tolerances.

7- Also measure exactly the diameter of the liner edge.

Attention: cavity corrosion of the external surface of the liners are created by poor maintenance of the cooling system and if this problem isn't solved it may cause cylinder liner to be perforated and finally water and oil inside the engine will be mixed.

Note: at the time of installment of piston or new bush, it is very important that these two parts completely fit each other and there is no any clearance between the liner, pistons and rings edges.

Installment of the cylinder liner.

1- clean inside and outside the cylinder liner and wash the sealing ring grooves with a solvent liquid.

2- Remove and completely clean all rust and deposits on cylinder blocks and hermetic sealing surfaces.

3- Inspect the cylinder for fracture and deformation and control it by clock gauge because exiting any deposit on the site of liner or residues of the previous O ring and deformation of the block cause dysfunction of the engine.

4- First, control the new liners in terms of their dimension and assemble them without O ring. It should be noticed that in this state the liners to be mounted without much pressure, it should be mountable only by using hand force. The knob on the liner should be measured while it is positioned on its seat.

5- Take out liner from cylinder clock and mount its O rings. Take care the O rings not to be winded. O rings should be smeared with grease.

6- After mounting O rings, insert the liner by a special brush. Avoid enforcing much force when inserting liner.

7- After mounting liners into the cylinder vlock, measure and inspect liners again to be ensured from lacking any possible damage or crack during mounting.
