1 Screw the connector (1) into the sparkplug housing hole and insert pressure into the compression chamber (min. 5 bar)
Only if cylinder head installed. Use assembly board if cylinder head removed.
2 Fit the guide sleeve (3) into the cylinder head and screw and align the bracing tool (2) in the cylinder head
S05.30-3006-01
3 Assemble the lever thrustor (5)
4 Place the assembly cartridge (4) inside the guide sleeve (3), hook the lever (5) in the bracing tool (2) and rest it lightly on the two bearing bolts of the assembly cartridge (4).
5 Apply slight pressure to the lever thrustor (5) and at the same time slowly turn the knurled screw of the assembly cartridge (4) to the right (arrow) until it is felt to fit properly into the gap of the valve collets.
S05.30-3007-10
6 Press lever thrustor (5) down as far as a stop (arrow). After this, exert slight pressure with your finger on the knurled screw of the assembly cartridge (4) (arrow).
Lever thrustor (5) should press as vertically as possible (sectional view) on the assembly cartridge (4) in order to avoid the assembly cartridge (4) jamming. Should the travel of the lever of the thrustor (5) not adequate, the clearance to the cylinder head can be enlarged by inserting the bracing tool (2).
7 Slacken assembly cartridge (4) and lever thrustor (5) and take off. The valve cotters are removed automatically.
