Installation
11. Screw the candles by hand until they touch the cylinder head, and then tighten them with a force of 25 Nm.
Attention! Install the spark plug wrench strictly perpendicular, avoiding distortion, so as not to damage the ceramic insulator.
12. Check up ignition coils, having wrung out tips of spark plugs with a plastic wedge. Spark plug tips and coil springs must not be damaged or deformed.
13. Reinstall the spark plug tips and make sure the rubber tips are firmly seated on the tips. Nozzles must not be deformed. In the event of a loose fit of the nozzle, protection against breakdown of the spark plug insulator is not provided.
14. Establish the block of coils of ignition together with tips on candles and fix the block.
15. Connect the multi-pin plug and secure it.
16. Screw in the ignition coil block mounting bolts and tighten them with a force of 20 Nm.
17. Fix the holder of the coil unit with a tightening torque of the bolts of 8 Nm.
18. Connect and secure the crankcase ventilation hoses.
19. Reinstall the cover of the ignition coil unit and secure it with bolts. Attach the crankcase ventilation hose to the holder.
Upgrading the Thread of the Spark Plug Socket
Attention! If it turns out that the thread of the socket on the cylinder head where the spark plug is screwed in is damaged, then this thread must be renewed. For cutting new threads, BERU offers a suitable set of tools. Using a special drill, turn off the damaged thread. The cylinder head does not need to be dismantled for this. Then cut a new thread in the socket and screw in the spark plug with a special sealing insert. Inserts provide firmness of landing of candles and the required level of compression.
