To run the engine with one unit cut-off , and assuming that the unit’s running gear is not disturbed , is as follows:
- The particular unit fuel pump roller will be lifted off its cam and fuel to the pump cut off.
- The hydraulic connection to the exhaust valve shut or blanked and the roller lifted off the
Cooling oil connection to and from the piston will be blanked or cut off.
The indicator cock of the particular unit kept open to reduce the back pressure.
Starting air connection to the manifold as well as the pilot valve on distributor will be blanked or cut off
The engine speed should be arranged at such an RPM such that vibration levels are not severe and the scavenge pressure matches with the T/C operation avoiding surge condition.
