10.3 If annular ball bearing (25) has been re-greased proceed to paragraph 10.5. If annular ball bearing (25)
has been replaced proceed to paragraph 10.4.
10.4 Measure width of outer race of rejected and replacement annular ball bearing (25) using a 2" 3"
10.4.1 If both annular ball bearing (25) widths are equal within +/ 0.001", proceed to paragraph 10.5.
10.4.2 If both annular ball bearing (25) widths are not equal within +/ 0.001", bearing gasket must be
replaced. Remove gaskets using an awl being careful not to damage the housing. Clean housing to ensure
all gasket material is removed from the output housing.
10.4.2.1 Install new annular ball bearing (25) into output housing (26) with anti-rotation slots facing up.
Apply a small amount of Mobilgrease28 to outer diameter of bearing to facilitate installation into housing
assembly.
10.4.2.2 Using 3 to 4 inch micrometer and micing bar, measure and record dimensions A and B shown in
Figure 15. Dimension A is top of output housing to seal plate assembly mounting surface. Dimension B is
top of output housing to bearing outer race. Obtain dimensions at three different locations to ensure reliable
calculations.
