Illustration 2. Bill of Material Gasket Kit fiche.The gasket kit usage information fiche classify the kits by engine location: 1) Upper structure, 2) Upper, central and lower and front structures, 3) Rear structure and water pump, and 4) Engine and transmission oil cooler, brake oil cooler, engine oil lines, fuel system, air compressor, fan drive and front/rear take-off within these classifications. Gasket kit part numbers are listed on the microfiche according to machine model, machine serial number, engine arrangement number and engine serial number. The machines are listed in ascending order by machine size -- that is, D3 through D10 Tractors, then No. 12 through No. 140 Motor Graders through the complete product line.
You must know the machine model, machine serial number, engine arrangement number and engine serial number to obtain the number of the needed gasket kit. Locate the machine model on the microfiche. Next, match the machine serial number with the corresponding engine arrangement and serial numbers. See Illustration 3. Find the correct classification, and then check the B/M Gasket Kit fiche to determine the exact contents of each kit. See Illustration 4.
