Installation

Doweling

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.

Inserting Dowel Pins

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.

Force Feed Lubrication

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.

Oil Mist Purge

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.
