5-STEP

With all bolts loose align machine to where it looks

aligned by eye. Set up laseralignment system.

Measure, diagnose, and correct Soft Foot with the

assistance of the laser system and feeler gauges.

Measure and correct alignment of the machine

to achieve the final alignment to the required targets within tolerances.

Print the report to document

the alignment.

With feeler gauge find obvious gaps and fill them with shims, taking care of any rough soft

foot condition.

Aim to have all soft foot readings within 2 mils (thou).

Save the alignment file.

The goal is to minimize any coupling strain, and ensure

that the machine is alignable.

Replace damaged shim packs with new, corrosion and crush resistant shims.

Re-tighten bolts to 100% torque.

Ensure the misalignment is less than 15 mils (thou)

at the coupling.

Visual inspection of the foundation, grout,

and baseplate.

Take two sets of measurements to

ensure repeatability.

Clean up: remove rust, scale, paint, dirt from under

and around the feet.

Safety: Lock-out and tag-out of the machines, etc.
