1. Remove all accessories and assemblies with their attaching parts as is necessary so that tool set J
7593-03 inay be used as shown in Fig. 5 and in A of Fig. 9.
Tool set J'7593-03, designed for use with standard size bearings, may be used to remove and install 0.010 inch
undersize and 0.020 inch undersize bearings by reducing the pilot diameter of the pilot J 7593-2, installer J
7593-3, remover J 7593-5, installer J 7593-6, and installer J 7593-15. The pilot diameter of these tools should
be reduced by 0.020 inch. This reduction in tool diameter does not materially effect usage on standard size
bearings. If the tools are used frequently, however, it may be advisable to purchase additional standard
pieces. Reduced diameter tools have not been released.
2. Insert the small diameter end of pilot J 7593-2 into the end bearing.
3. Then, with the unthreaded end of shaft J 7593-1 started through the pilot, push the shaft through the
block bore until the end of the shaft snaps into remover J 7593-5.
4. tIow drive the end bearing out of the cylinder block. The nearest intermediate and/or center bearings
can be removed in the saine manner. The large diameter end of pilot J 7593-2 will fit into the camshaft bore
and is used when removing the other end bearing and any remaining bearings.
