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.
