Pistons with connecting rods - assembly
Pistons and connecting rods are supplied separately and, if the cylinder block has been bored, you need to purchase pistons with rings and pins of the appropriate repair size.
CAUTION: The piston pin holes in the pistons are offset and it is important that when connecting the piston to the connecting rod, the mark on the piston head coincides with the mark (7) on the connecting rod.
The finger must be prepared for assembly in advance.
When checking, the finger should fit tightly into the piston bosses using the force of the thumb.
Before directly assembling the piston with the connecting rod, place the piston pin and guide sleeve on the holder, securing it with a bolt. The bolt must not be tightened too much to avoid it jamming.
Install the piston with the connecting rod on the prism of the device.
CAUTION: The piston and connecting rod timing marks must be located on the same side.
Insert the pin into the desired position using the tool of your choice. After pressing, check the correct installation of the pin, and also lubricate the pin through the holes in the piston bosses.
Install the pin retaining rings.
Now you can install the piston rings.
To check the correct assembly of the piston with the connecting rod, tilt the connecting rod at a slight angle, while the piston head should drop under its own weight.
