When maintenance requiring disassembly of the power end is performed, the following
clearances should be checked to see if they are within factory specification or within
maximum allowable limits. Additional clearance is allowed for component wear. This
additional clearance is a maximum of .002 inches of total diametral wear that can be
added to the clearance values in Table 6. For radial clearance, use ½ of the total
diametral value.
All dimensions are shown in Inches.
