Piston :

Piston and pin are supplied to market after careful testing and checking. Each piston is provided

with its pin. They are lubricated with protective oil and then packed. Our company has seen no

necessity to manufacture pistons and pins in different colouring. It is recommended to equip

each piston with its own pin and cylinder that are packed in same box. Fitting of pistons must

be done according to signs and directions which are on top of the piston.

Pin :

According to the features of material and tolerance standards, pins are produced and assembled

to the pistons. Tolerances can differ for each type of piston which also• depends on experiences.

The performance of the engine is directly influenced by how pin is assembled on the piston and

connecting rod. The regulation with shrink fit has changed to lighter pin fit and general view

using this way. If the pin is manufactured with oversize dimension, pin hole must be warmed

up before fitting. Never fit and replace the pin by using force. The shrink fit must be done by

using suitable tools and equipments. The circlips are also assembled to the piston, as a result

it is introduced in this way of packing.

Rings :

Rings must be installed with great care. Opening the rings more than necessary midht cause

permanent deformation which will also influence the performance of the engine. Rings must be

installed according to their number and in suitable angles.

General :

Pistons that are manufactured MOGESAN factory are ready to install into suitable liners and

connecting rod without needing extra functions. All external matters, dust, foreign substances

must be cleaned from honed cylinder, block, crankshaft and cylinder head before fitting. Oiling

matters can be dried because of long time period. In this case the piston and pin must be

recleaned and oiled. To berakin piston should run the engine with %70-80 power and revolution.

Oil and oil filter must be changed in proper time and according to intervals.

INSTALLATION PROCESS OF CYLINDER LINERS

The are two types of cylinder liners which are produced :

* Dry Liners * Wet Liners

Installation of wet cylinder liners :

The bores and in particular the seats in the cylinder bloks must be carefully cleaned. Insert

the cylinder liners before final installation without sealing rings. Control and chech the movement

and correct seating. For final installation use soap on the sealing rings to slide in the cylinder

liner easy into the engine block. Aft er fitting the liner with the appropriate sealing rings check

the cylinder diameter and the collar.

Installation of dry (semi) cylinder liners :

Before the liner i•s installed into the cylinder liner block must be carrefully cleaned and checked

for for dimensional accarycy and distortion. The cylinder liner must be pressed with power

between 3000 kg and 5000 kg into the block. It is important that the bore is circular and

cylindrical. And it must be rehonned without any movement from the axis.
