The replacement of the connecting rod and piston group with a pressed-in pin is carried out in the same sequence as the replacement of the connecting rod and piston group with a floating pin, but has one feature. The pin is installed in the connecting rod "hot", and is not fixed with retaining rings.
Warning! Connecting rod and piston group parts with a floating pin are not interchangeable with connecting rod and piston group parts with a pressed pin.
To complete the work you will need:
- device for pressing out the piston pin;
- piston pin installation mandrel;
- technical hair dryer (heat gun).
Disassembly
1. Remove the piston rings from the piston (see "Piston rings and connecting rod bearings - replacement").
2. Using the tool, press out the piston pin.
3. If there is no special device, the pin can be pressed out in a large bench vice using a mandrel. As a stop, we use a wooden block of sufficient thickness with a hole drilled in it for the pin.
4. Remove the piston from the connecting rod.
Assembly
1. We select pistons for cylinders and pins for pistons (see "Connecting rod and piston group with a floating pin").
Warning! The engine must be equipped with pistons and connecting rods of the same weight class.
2. Install the piston pin on the mandrel.
3. Clamp the connecting rod in a vice and heat its upper head to a temperature of 200-250°C using a heat gun.
4. Place the piston on the upper head of the connecting rod and center their holes with a mandrel.

Warning: When assembling the connecting rod with the piston, make sure that the marking on the connecting rod and the marking on the piston are on the same side.
5. Pressing the piston against the connecting rod head in the direction of the arrow, in one quick movement insert the finger into the holes until the mandrel stops against the piston.
6. Remove the mandrel from the finger.
7. Put the rings on the piston and install the piston into the cylinder (see "Piston rings and connecting rod bearings - replacement").
