Alignment Troubleshooting
Problem
Probable Cause
Treatment
Unable to obtain horizontal
alignment, angular or parallel
Driver feet bolt bound
Loosen pump hold down bolts and slide
pump and driver until horizontal
alignment is achieved
Base plate not leveled properly,
Probably twisted.
Determine which corners of the
baseplate are high or low and remove
or add shims at the appropriate corners
and realign.
Unable to obtain vertical
alignment, angular or parallel
Base plate not leveled properly,
Probably tilted
Determine if center of baseplate should
be raised or lowered and correct by
evenly adding or removing shims at the
center of the baseplate.
