6.3 Checking Sideplate Clearance
1.
Remove the bearing housing caps, fit the shim packs and then
refit the bearing housing caps leaving a clearance of 1-2mm
between the caps and the sideplates.
2
Repeat the exercise of tightening each bearing housing cap,
and recording the DTI reading. Repeat for the opposite end
of the compressor keeping the first end tightened.
6.4 Checking the
‘Float’
NOTE
To increase the clearance
shims are removed and to
decrease clearance shims
are added.
With the sideplate clearances set, a final check of the
machine is to check the
‘float’.
1. Push the rotor toone end.
2. Zero the DTI on the end of the shaft.
3. Push the rotor to the opposite end and record the
reading.
This reading should equal Free Movement Check
(Section 6.1) minus both fixed clearance
measurements (Section 6.3)
NOTE
After clearance setting, turn
the rotor to check that the
blades fall freely from the
rotor slots. 6 blades will
drop on a 360
˚ turn.
