4.  Inspect  the  shaft  (9)  and  sleeve  (16)  for 

grooves or pitting, replace if any are found. 
Ensure  the  shaft  bearing  fits  are  within  the 
tolerances in Table 4. Also, check that shaft 
runout does not exceed the values in Table 
5. 

5.  Inspect the bearing frame (13) and pedestal 

(14) for cracks. Remove all loose foreign ma-
terial  from  inside  the  frame.  Ensure  that  all 
lubrication passages are clear. 

6.  Inspect  stem  plate  (23)  for  pitting  or  wear 

greater than 1/8” deep, and make sure that 
the gasket surface is clean. 

7.  Inspect  the  bearing  housing  (6)  for  cracks 

and pitting. Check that the bore is within the 
tolerances. Replace bearing housing if bore 
exceeds these tolerances. 

8.  Inspect  the  bearings  (5  &  10)  for  contami-

nation or damage. If bearing damage is not 
from normal wear, correct the problem be-
fore using pump. Do not reuse bearings.
