BY-PASS VALVE M BY-PASSVALVE HtGH PRESSURE STEAM Figure 145 Testing Low-Pressure Cylinder Packing. Engine on top quarter. Starting valve S open, as in Fig. 145. Reverse lever in back motion. This allows steam to flow through starting valve into low-pressure steam COMPOUND LOCOMOTIVES 3°9 chest P, thence through front low-pressure steam portR to front end of low-pressure cylinder J. If any steam shows at back low-pressure cylinder cockK, the low-pressure piston packing is blowing. Alwaystest low-pressure piston packing in this position. Testing Piston Packing Sleeve, Between BY-PASS VALVE BY-PASSVALVE J HIGH PRESSURE STEAM Figure 146 Engine on top quarter. Starting valve S closed, as inFig. 146. Reverse lever in forward motion. Thisadmits steam from high-pressure steam chest E, through steam port C, to back end of high-pressurecylinder F only. 310 LOCOMOTIVE ENGINEERING If steam now flows from front low-pressure cylindercock L, the piston sleeve G is worn and leaking, Starting Valve in Position for Working Simple, shows section through high-pressure valve, steamchest and starting valve. By-pass valve M removed,but having valve-cap replaced. For working simple,starting valve lever T should be vertical, which placesvalve S in forward position, opening both ports Nand O.
