Fabricated Tools are required for the disassembly and assembly of the variable speed fan drives that are described in the References. Table 1 identifies the Fabricated Tools and the corresponding Illustrations. The illustrations provide the dimensions for making the Fabricated Tools.
The Fabricated Tools that are identified in Table 1 can be used to service the variable speed fan drives that follow: the former 100-8105 Fan Drive Gp, the former 129-9494 Fan Drive Gp, the former 133-5969 Fan Drive Gp and 163-2592 Fan Drive Gp. The Fabricated Tools that are identified in the References are the Fabricated Tools that are identified in Table 1.
The Fabricated Tools that are identified in the Service Magazine, 30 March 1998, "Use FT2461 Pressing Bar, FT2462 Pressing Tube, FT2463 Ring, FT2464 Plate, FT2465 Plate, FT2466 Mounting Plate, And FT2467 Rotating Plate To Disassmeble and Assemble Variable Speed Fan Clutch" and the Service Manual, SENR8603, "Variable Speed Fan Clutch" can NOT be used to service the 163-2592 Fan Drive Gp .
If a former variable speed fan drive must be rebuilt or repaired, the former variable speed fan drive should be replaced by a 163-2592 Fan Drive Gp .
Note: All of the Fabricated Tools that are identified in Table 1 are made of SAE 4140 steel.
Note: After the new tool is fabricated, mark the number (FTXXXX) of the Fabricated Tool on the tool.
