Doweling the motor (and driven unit) accomplishes the 
following: 

1. Restricts 

movement. 

2.  Eases realignment if motor is removed from base. 
3.  Temporarily restrains the motor, should mounting 

bolts loosen. 

 

The following procedure is recommended: 

a.  Check the alignment after the unit has been in 

operation approximately one week. Correct as 
necessary. 

b.  Using pre-drilled dowel holes in motor feet as 

guides, drill into the mounting base. 

c.  Ream holes in the feet and base to the proper 

diameter for tapered dowel pins.  Clean out the 
chips. 

d. Insert 

dowel 

pins. 

 
 

If force feed lubrication is used, flush lubrication lines 
thoroughly to make sure the lines are clean before 
connecting lines to bearing housings.  Be sure that 
bearing cavities are filled with oil to the proper level 
before starting.  See motor outline drawing to 
determine proper oil level.  Be sure that proper oil 
pressure and flow are provided by the supply system.  
Verify that the oil drain flow agrees with the factory 
requirements.  The orientation and size of oil drain 
piping supplied with the motor must not be altered.  Oil 
drain piping should be of the same size or larger from 
the motor piping to the oil sump.  Piping must slope 
downward. Pressure build up in the drain line between 
the oil sump and the motor bearing housing can lead to 
oil leakage.  Document readings for warranty 
information. 

 
 

When connecting 500/580 frame motors for oil mist 
purge, it is important to note that the drive and non-
drive end bearing cavities operate at different 
pressures. To avoid high or low oil levels, care should 
be taken when connecting the system so that cavity 
pressures are maintained.
