To check parallel alignment
1.
Flexible couplings:
Place a straight edge across both coupling hubs at four points 90° apart. The unit will be in paral-
lel alignment when the straight edge rests evenly on both halves. See Fig. 9.

2.
"Spider-Insert" Couplings
Place a straight edge across both coupling hubs at four points 90° apart. The unit will be in paral-
lel alignment when the straight edge rests evenly on both halves. See Fig. 9.
3.
Flexible Spacer Couplings
Place a dial indicator on one hub and rotate that hub 360° while taking readings on the outside
diameter of the other hub. When indicator does not deflect more than .002" total, parallel align-
ment is achieved. See Fig. 10.
