gauges and a micrometer. Small wooden wedges can be inserted between the shaft and the I.D. 
of the stuffing box to hold the shaft in place. 
 
4. 
Follow step 2-B and bring the coupling (shaft) alignment to within .002” TIR. DO NOT
READ OFF OF THE PUMP COUPLING AS IT IS A SLIP FIT TO THE SHAFT, Read the shaft! 
Once the alignment has been completed and the motor hold down bolts are tight, set the coupling 
lift using 4 coupling bolts. Set up a dial indicator and read the lower shaft runout below the pump 
coupling and above the stuffing box ext. You should read .005” or below. If you read higher than 
.005” uncouple the unit and rotate the motor coupling one bolt-hole, recouple, read the lower 
shaft runout again. Repeat until the lowest runout number is achieved and then complete the 
coupling procedure. 
 
 
10.3 Gasket eliminator application.
Gasket eliminator is an anaerobic gel flange sealant loctite 515 which is ready to use and cures 
at room temperature when it is isolated from air contact. 
Gasket eliminator (Loctite 515) is used for sealing metal faces or flanges and provides resistance 
to pressure immediately after assembly of flanges. 
 
10.3.1 Directions for use on stainless steel and other passive surfaces 
For best performance surfaces should be clean and free of grease. 
Apply an aerosol layer of Loctite 7649 primer over both surfaces to be joint in order to activate 
the surface 
Apply Loctite 515 manually as cord way over one surface to be joint 
Flanges should be tightened as soon as possible after assembly to avoid shimming. 
 
10.3.2 Directions for use on carbon steel surfaces
For best performance surfaces should be clean and free of grease. 
Apply Loctite 515 manually as cord way over one surface to be joint 
Flanges should be tightened as soon as possible after assembly to avoid shimming.
