10 October 1984 Mr. Kandy Burlison ' From: John Holz Subject: NON-ASBESTOS BRAKE . LININGS Mining Engineering has completed the program to incorporate non-asbestos lining material on all production non-disc brake ap plications. The disc brakes applied to mining shovels and draglines have always used sintered metal linings and do not contain asbestos. All brake drawings that did specify asbestos lining material have been changed to non-asbestos material and released. A tabulation showing the "old" vs. "new" (ie, asbestos vs. non-asbestos) part numbers is attached. Brake part numbers already specifying non-asbestos material did not change. The non-asbestos lining material specified for drum brakes is P&H 3022, and the purchased non-asbestos lining material for propel "V" brakes is described by the vendor H.K. Porter as specification NA104. The new non-asbestos brake Linings were released to supersede the old asbestos linings, with instructions to use up existing stock of asbestos material. It is imperative to establish a system to identify and exhaust the existing stock of asbestos linings at the stocking level to insure a complete conversion to non-asbestos lining across the board for mining equipment as quickly as stock wilL permit. . Material Management is requested to inform Engineering which pro duction stock order non-asbestos linings will become effective for the various brake assemblies in order to be able to state this effectivity in sales and marketing efforts. In keeping with the policy to eliminate asbestos lining materiaL from the complete mining equipment product line, brake linings for older non-production brakes should be changed to non-asbestos material before they are re-purchased for stock replenishment. Upon notification, Engineering will advise Purchasing the new Hamischfeger P&H SCF-P&H-1975 10 October 1984 - Page 2 NON-ASBESTOS BRAKE LININGS material and part number to order non-asbestos linings and will release new or revised drawings incorporating the new lining material. /jkh Attach: Brake Tabulation cc: H.
