2.4 Method of levelling baseplate using wedges or shims
Level the baseplate by using a machinist's level on the machined surfaces of the pump and driver
pads. Levelling is best achieved by adjusting the shim pack thickness under each holding bolt.
Carefully raise the baseplate by using either the baseplate jacking screws provided or by levering
with a suitable pinch bar or by installing a low level hydraulic jack.
Adjust the shim pack thickness and lower the baseplate.
Repeat this procedure in a logical manner at each bolt position until the baseplate is both straight
and level. A degree of 0.0035 inch per foot (.25mm per metre) length is achievable on most units
with a maximum of 0.005 inch per foot. (.40mm per metre length).
When the baseplate is level, pull down the foundation bolts so they are snug. This may have
disturbed the baseplate, so re-check the levels.
Ensure that shaft alignment per Section 2.6 can be achieved prior to grouting the baseplate.
