Installation of the starting valve in the cylinder head is carried out in reverse order. Renew 0-ring (9) and, if

necessary, packing rings (4). Tighten hex. nut (6) with socket spanner, while holding the starting valve (1) with

a screwdriver in the slot of the valve disc.

Counterlock hex. nut (7) with socket and hex. nut (6) by means of the socket spanner. Mount circlip (12).

Before placing on cover (8), check starting valve for easy movement.

In the case of improper locking of hex. nuts (6) and (7), there is a risk of the nuts loosening and the

starting valve falling into the cylinder. This can result in very serious consequential damage.

In the case of the V-type engines, starting valves are fitted in one bank of cylinder engine, and B1 to 8

of the 16-cylinder engine. The cylinder banks A1 to 6 and A1 to 8 respectively are provided with

blanking plugs.
