INSTALLATION OF DISASSEMBLED TYPE T31 STEELFLEX
®
COUPLINGS
1. MOUNT SHAFT HUBS · Lockout starting switch of prime mover. Mount shaft hubs on their respective shafts so that hub face is flush
with the end of the shaft. If hub is furnished for an interference
fit,
heat in an-Oil bath as instructed on Page 1. Position units for approximate distance
between shaft ends with minimum angular and offset misalignment.
2. MOUNT EACH HALF SPACER - Stretch the seal and carefully roll
it
over hub teeth into position. Carefully position each half spacer on register of flanged
hubs and fasten parts together. Torque fasteners to value specified below left.
3. GAP AND ANGULAR ALIGNMENT - Use a spacer bar equal in thickness to the gap as specified. Insert bar, as shown above right, to same depth at
90-
intervals
and measure clearance between bar and hub face with feelers. The difference in minimum and maximum measurements must not exceed the ANGULAR limit
specified in Table 1.
4. OFFSET ALIGNMENT - Align so that a straight edge rests squarely (or within the limits specified in Table 1) on both hubs and also at 90° intervals. Check with
feelers. The clearance must not exceed the OFFSET limit specified in Table 1. Tighten all foundation fasteners and repeat Steps 3 and 4. Realign coupling if
necessary. NOTE: Use a dial indicator for more accurate alignment.
S. INSERT GRID - Pack gap and grooves with lubricant before inserting grid. When grids are furnished in two segments, install them so that all cut ends extend in
the same direction. This will assure correct grid contact with the lug in the cover and permit cover installation. Spread the grid slightly to pass it-over the coupling
teeth and then seat it with a soft mallet. Pack additional grease between and around the grid and then wipe off the excess flush with top of grid.
6. COVER MATCH MARKS • Assemble the covers with the match marks on the same side. For vertical or inclined couplings, assemble the covers with the
match marks (and lugs) UP, or on the high side.
7. INSTALL COVER· Align seals with rover grooves. Position covers per Step 6 and insert gaskets at both joints. For Sizes 1020 thru 1070, position nut in hex
seats. insert all fasteners and torque to value Specified in Table 1. Insert pipe plugs.
8. LUBRICATION - Lubricate annually. Refer to Page 1 for recommended lubricant specifications and to Table 1 for amount of lubricant required. When lubricating
remove both pipe plugs and insert a standard lubrication fitting in one hole. When grease flows from the vent hole, replace both plugs. Wipe off excess grease.
