5 — Offset Alignment
Align so that a straight edge rests squarely on both hubs as
shown above and also at 90° intervals. Check with feelers. The
clearance should not exceed the INSTALLATION OFFSET limit
specified in Table 1. Tighten foundation bolts and repeat Steps
4 and 5. Realign coupling if necessary. Use a dial indicator if
hub extension is too short for accurate use of a straight edge.
6 — Insert Center Plates Into Spacer &
Assemble Coupling
Position Center Plate in both ends of spacer counterbore. If
Center Plate diameter is stepped, assemble small diameter
side into spacer. Position spacer (with Center Plates) between
hubs. (For GL32-4, insert the gap disc between each hub and
spacer). Insert gasket at each flange connection and assemble
sleeves to spacer. Use only the fasteners furnished with
the coupling.
IMPORTANT: Tighten fasteners to torque specified in Table 4
on Page 6.
7 — Lubricate
Insert a lube fitting into one lube hole and remove opposite
plug for venting. Fill to ONE-HALF of the amount of lubricant
specified in Table 1. REPEAT the procedure for other half
coupling and then INSERT ALL LUBE PLUGS. IMPORTANT:
Over lubrication may restrict the sliding action of the coupling.
BI-ANNUAL MAINTENANCE
Re-lubricate coupling if using general purpose greases. If
coupling leaks grease, is exposed to extreme temperatures,
excessive moisture or frequent reversals; frequent lubrication
may be required.
ANNUAL MAINTENANCE
For extreme or unusual operating conditions, check coupling
more frequently.
1. Check alignment per Steps 4 and 5, Pages 4 and 5. If the
maximum operating misalignment values are exceeded,
realign the coupling to the recommended installation
values. See Table 4, Page 6, for installation and maximum
operating misalignment values.
2. Check tightening torques of all fasteners.
3. Inspect seal ring and gasket to determine if
replacement is required.
4. Re-lubricate coupling if using general purpose grease.
