Tender Sieve Boxes
 |
There
are two sieve boxes mounted on the tender, one each side of the vehicle.
Their purpose is to ensure that no 'foreign bodies' in the tender tank
can pass to the injectors. Each of the
sieve boxes supplies water to one of the injector water taps.
In this view the driver's side sieve box is about to be lifted into position using wedges and crowbars. The shut off tap has yet to be fitted. |

The sieve box in position and secured by nuts and washers. The (now fitted) shut off tap, when closed, stops any flow of water from the sieve box to the injector tap. This means that the flap at the bottom of the sieve box can be opened, the sieve removed, cleaned and refitted without draining the tender tank. It also means work can be carried out on the injector without wasting water. |

Pipework fitted to carry the water forward to the injector tap via the flexible hose. |
