All the ports in the body of valve erly ground in its cylinder, using oil onlyto grind the same. After packing ringhas been thoroughly fitted to its cylinderthe brass plug should be put back in pis-ton, as the leaving out of this plug willdestroy the quick-action feature. All the parts, including the slide valvebody, should be thoroughly wiped out withrags. Do not use waste. The conditionof the slide valve should be noted, and ifnecessary it should be faced. Care shouldbe taken if the exhaust slide valve has beenremoved for facing purposes that in re-placing the same on the piston stem o. should now be thoroughly blown out andtriple valve cylinder should be thoroughlycleaned with waste saturated with kero-sene. Feed port should not be feed grooves should be thoroughlycleaned out. It is also important to no-tice the small port in the vent valve piston,which should be well cleaned, as it is veryessential that this port be opened so it canperform the function intended. The brassplug in the vent valve piston should notbe removed only when a new packing ringi* applied. Then this plug should be re-moved so that packing ring can be prop- have the small shoulder or the end thathas the exhaust port nearest the slidevalve facing the auxiliary side of the pis-ton. The long shoulder should be nextto the graduating valve. This is veryimportant, as it will be impossible to retainair in the brake cylinder if the slide valveis put in a reverse position.
