Pic. 2.178. Installing the piston on the ring: 1 - ring; 2 - clamp
Install the ring B10 and the piston supported by the ring on the prism (oriented in the correct position) and fasten all parts with a clamp (pic. 2.178).
Make sure the piston pin bore is aligned with the B10 ring bore.
Lubricate the centering mandrel and piston pin with engine oil.
Insert the piston pin into the assembly and check if it rotates freely. Center the piston if necessary.
The following operations must be carried out quickly to prevent the connecting rod head from cooling.
When the piece of solder reaches its melting point (turn into a drop):
- remove a drop of solder;
- insert the centering mandrel into the piston;
- insert the correctly oriented connecting rod into the piston;
- quickly lower the piston pin until the centering mandrel rests on the bottom of the tool.
Make sure that the piston pin does not protrude from the piston in any position of the connecting rod.
