Proper care in installing and aligning will permit couplings to operate to full capacity, compensate for misalignment, and
provide very good service life.
1. Inspect shafts and hubs bores and make sure they are free from burrs. Check for the proper t of the keys to the shafts
and hubs.
2. Fit the couplings hub(s) so that the shaft end(s) is/are ush with the machined face of the ange. If the hub is bored for
interference t, the hubs should be heated then quickly positioned on the shaft. Do Not spot heat or heat above 300°F
as it may cause distortion.
3. Move the equipment to be connected into position. Set the gap to the required “D” dimension. See Fig. 1 or 2.

ASSEMBLY
4. Assemble the coupling using gures 1 or 2 as a guide. Do not drive or force bolts into position. All nuts must be tight-
ened to the value shown in Table I with lightly oiled threads.
TABLE I (Lightly oiled threads)
ALIGNMENT
5. After preliminary alignment and complete assembly, secure a dial
indicator to one hub as shown in gure (3) and indicate face of the
other hub or adapter as shown. Indicator mounting is optional.
6. Rotate the coupling to nd minimum indicator reading. Set the
indicator for zero reading.
7. Again, rotate the coupling 360° to check misalignment.
8. Adjust position of connected equipment until indicator reading is
within the allowable variation shown in Table II.

TABLE II Total indicator reading inches.
IMPORTANT: To ensure unlimited life re-check alignment after a short period (one to two hours)
of actual running. At this time also re-torque bolts and nuts to values to Table I. If
equipment is portable this should be done each time the equipment is moved.
WARNING
ROTATING EQUIPMENT IS POTENTIALLY
DANGEROUS AND MUST BE PROPERLY
GUARDED. THE USER SHOULD COMPLY
WITH APPLICABLE SAFETY CODES IN
ACCORDANCE TO OSHA STANDARDS.
