Drive Coupling Alignment
QSI 245-750
These QSI units are direct coupled between the airend
and the drive motor through the use of a transition piece.
Realignment of the coupling is not necessary.
QSI 1000-1500
It is necessary to check and correct the coupling
alignment between the compressor and the motor. This
service is vital to the life of the motor and compressor
bearings and must be performed after the unit has been
installed in its final location and prior to start-up. If the
unit is ever moved from its original site, the alignment
must be checked again. The QSI series compressors
utilize a two piece flexible element bolted to steel hubs
on the compressor motor shafts. The following steps will
ensure a properly aligned coupling:
1) Tag and lock out all power to the unit.
2) Remove coupling guard.
3) Unbolt and remove one-half (1/2) of the flexible
element. Leave the remaining half bolted to both
steel hubs.
4) Using one of the existing 3/8” bolt holes in the
compressor hub, attach a dial indicator mounting
stud or bolt in firmly.
5) Attach a dial indicator to the mount with the
necessary hardware to allow the indicator plunger to
contact the motor hub.
NOTICE!
Four viewpoints need to be checked. Angular and
parallel, as view from the top. Angular and
parallel, as viewed from the side.
Do not operate the unit without both coupling halves and
guards in place.
