Preparation

WARNING

Danger: Some gas can leak during the removal of the GAV. Do not

use equipment that can cause a spark. Make sure that all equipment

that can case a spark is not in the work area. This will prevent an

explosion, or a fire.

1) Stop the engine, refer to the Operation Manual, 0310

−

1 paragraph 3

2) Set to off the main bearing oil pumps (use the service pump for tests).
3) Make sure that the pressure in servo oil supply pipes is zero.
4) Make sure that the pressure in the gas pipe, high pressure pipe and lubricating

oil pipe is zero.

5) Make sure that the drain from the gas control valve is open.
