For Type G62 couplings,
use a spacer bar equal in thickness to
gap specified in Table 4. For Type G66, use a spacer bar equal
in thickness to the “X” dimension specified in Table 4. Insert bar,
as shown above, to same depth at 90° intervals and measure
the clearance between bar and hub face with feelers.
The
difference in minimum and maximum measurements must not
exceed the INSTALLATION ANGULAR limit specified in Table 4.
4 Offset Alignment
Clamp a dial indicator to the rigid hub as shown (on the flex hub
for Type G62) and rotate the hub one complete turn. The total
indicator reading DIVIDED by two must not exceed the
INSTALLATION OFFSET limit specified in Table 4. For the
ANGULAR check, sweep the face of the adjacent hub as near the
OD as possible. The total indicator reading must not exceed the
ANGULAR limit in Table 4. Realign coupling if necessary.
CAUTION:
Consult applicable local and national safety codes
for proper guarding of rotating members. Observe all safety
rules when installing or servicing couplings.
5 — Insert Gaskets and Assemble Coupling
Grease the hub teeth. Insert gasket between brakewheel and
flanges as illustrated and bolt parts together. For G62, assemble
sleeves with lube holes approximately 90° apart. Use only the
fasteners furnished with the coupling. IMPORTANT: Tighten
fasteners to torque specified in Table 4.
6 — Lubricate
Remove all grease plugs from side of flanged sleeves. Fill with
recommended grease until an excess appears at an open hole;
then insert plug. Continue procedure until all plugs have been
inserted.
CAUTION:
Make certain all plugs are inserted after
lubricating coupling.
7 — Assembled Coupling Alignment Check
The alignment can be checked without disassembling the
coupling as shown at left. Determine “W” by measuring
distances “W”max. and “W”min. between flex hub and sleeve
using a depth mic or feeler gages. The difference between
“W”max. and “W”min. must not exceed the “W” value given in
Table 4. Check “W” at each coupling end.
