Problem
Probable Cause
Remedy
Cannot obtain horizontal (Side-
to-Side) alignment, angular or
parallel
Driver feet bolt bound. Loosen pump hold down bolts and slide pump and
driver until horizontal alignment is achieved.
Baseplate not leveled proper-
ly, probably twisted.
Determine which corner(s) of the baseplate are high
or low and remove or add shims at the appropriate
corner(s) and realign.
Cannot obtain vertical (Top-to-
Bottom) alignment, angular or
parallel
Baseplate not leveled proper-
ly, probably bowed.
Determine if center of baseplate should be raised or
lowered and correct by evenly adding or removing
shims at the center of the baseplate.
3.7 Grout baseplate
1.
Clean areas of baseplate that will contact grout. Do not use oil-based cleaners because grout will
not bond to it. Refer to grout manufacturer’s instructions.
2.
Build dam around foundation. Thoroughly wet foundation (Fig. 15).
3.
Pour grout through grout hole in baseplate, up to level of dam. Remove air bubbles from grout as it
is poured into place. Non-shrink grout is recommended (Fig. 15).
