Note: Drive shaft end-float at fi nal drive position mus t no t allow coupling hub faces t o contact,
or the coupling shroud to bind.
Preliminary Alignment
To get within di al indicator ra nge, roughly a lign the equipm ent as shown in Figure 37 and as
described below.
Place a straight edg e across the OD of one coupling to the OD o f the other. Measure t he gap
between the straight edge and the OD of the second coupl ing with a feeler gage. T hen , by
adding or removing shims at each corner, raise or lowe r the equipment by the mea sured
amount.
In a similar manner, measu re the shaft offset from si de t o side and jack the equipmen t over
as required to correct.
