G This manual includes illustrations of the packing sets for each model pump Generally once the plunger has been removed from the pump the packing can be exposed for removal by completely removing whatever device is used to tighten the packing i e the packing or stuffing box nut or gland There will be various amounts of metal rings and packing components depending upon the type of packing and the model of pump refer to appropriate illustration or chart After the removal of all rings and equipment from the stuffing box thoroughly clean it and inspect for damage which might keep the new packing from working properly If the stuffing box is in satisfactory condition install the new packing as per the appropriate illustration It is a good idea to lubricate new packing with a light oil prior to installation Most of the standard packing used in pumps should be tightened with the original equipment packing wrench while the pump is running under normal operating pressure After a two or three hour run in check the packing for tightness and re adjust as necessary Packing should be checked for tightness on a periodic basis but it is not a good idea to attempt to periodically tighten the packing as part of routine maintenance This tends to wear out the packing prematurely When the packing leaks in an excessive amount it should be replaced There is no value in constantly re tightening leaking packing If your pump is equipped with optional spring
