Soft Foot; Drive Belts; Pulleys - Fluke PRUFTECHNIK PULLALIGN Bedienungsanleitung

Notice
Such problems must be corrected before proceeding with
pulley alignment.

Soft foot

Inspect the moveable machine for 'soft foot'. Feeler gauges can be
used under a loosened foot to measure the gap. Shim the machine
foot with the largest amount of gap (the amount indicated with
the feeler gauges) until no reading is larger than 0.05 mm (0.002"
or 2 mils). Use PRÜFTECHNIK PERMABLOC
shims. Severe 'soft foot' can distort the machine frame when
bolted down, causing damage to seals and bearings of the
machine. It could also lead to high vibration on the machine
bearings.

Drive belts

Belts are easily replaced by simply moving one pulley toward the
opposing pulley. Belts must be replaced with new identical belts.
Belts must never be forced onto a pulley as this will damage the
pulley or affect the tensile properties of the belt. For a multiple-
belt drive, all belts must be replaced together.
Only belts from the same manufacturer should be combined
together, preferably a factory-matched set. The replaced belt must
be examined for any noticeable defects such as cracking, gouges
or crumbling, and for signs of slippage - which is indicated by
glazing.
The condition of the worn belt is a good indication of the type of
misalignment or other problem that might be in play. Belts must
be changed as soon as undue wear is detected.
New belts must be properly stored. They should be kept in a cool,
dry place with no exposure to direct sunlight or heater drafts.
They must not be hang from single pegs.

Pulleys

If installing new pulleys and belts, ensure you have the correct
belt–pulley combination and the correct size belts.
If aligning existing pulleys, inspect the pulleys and belts with a
sheave gauge to ensure they are not worn. Worn components
must be replaced.
