2. Insert the lower seat 18, valve springs 21.
3. Before installing the guide gasket 20, it is necessary to install a special plastic sleeve on the valve stem (is included in the gasket kit), to facilitate the transfer of the gasket lip through the channels on the valve stem without damaging it.
4. Insert the guide seal through the valve stem and press it onto the guide by hand or using a metal tube (photo 1.121). The tube should have an outer diameter approximately equal to the outer diameter of the seal. Remove the plastic sleeve.
5. Place springs 21 and upper cup 2 on piston rod 19, then compress the spring with the tool and place conical safety catches 3. It is often easier to insert the safety catches by lubricating them from the inside with grease. This way they will not fall out of the grooves during installation.
6. Repeat the steps for the remaining valves. When finished, tap the end of each valve stem with a brass hammer to seat the fuses. The head should lie on its side so that the valves do not hit the table.
