3.3 Shaft Alignment
 In order to achieve optimum service life of the coupling, shafts must be aligned.
 Initial misalignment should not be more than 25 % of maximum misalignment
(Refer Table 3).
Table 2 : Method of misalignment
Method
Parallel/Radial
Angular
1
Using dial gauge
Using dial gauge
 Clamp dial gauge on driven hub
 Note the reading at each quarter rotation of hub by rotating one end.
 P or X is half the Total Indicated Reading (TIR) shown on dial gauge
2
Using straight edge
Using verinier calliper
 If the field constraints do not permit to use dial gauge then alternatively use
straight edge & vernier calliper to measure parallel and angular alignment
respectively.
