g. Loosen setscrews (5) and remove the hubs (4) from the shafts.
h. Remove seals (3).
i. Using emery cloth remove any burrs or scars from the shafts.
a. Slide the seals (3) on the shafts.
b. Slide the hubs (4) on the shafts but do not secure setscrews (5).
c. To align coupling hubs perform the following steps.
Insert a spacer bar, 0.125 inch of equal thickness, to the same depth at 90o intervals between hubs.
Insert a feeler gauge between the spacer bar and the hub and measure the clearance. The
difference in minimum and maximum measurements must not exceed the angular limit of 0.010
Set a straight edge squarely across both hubs at 90 intervals and check with feeler gauge. The
clearance must not exceed the offset limit of 0.010 inch.
Secure setscrews (5) in hubs (4) and repeat steps (1), (2) and (3) above. Realign coupling as
d. Pack the gaps between hubs and grooves with grease.
When grids are furnished in two or more segments,
install them so that all cut ends extend in the same
direction to permit easy cover installation.
e. Spread grid (2) lightly to pass over coupling teeth and tap in place with a soft mallet.
f. Pack spaces between and around grid with grease and wipe excess flush with top of grid (2).
g. Position seals (3) on hubs (4) to line up with cover (9) grooves.
h. Position gaskets (6) on flanges of lower cover half.
i. Assemble covers (9) so that the match marks are on the same side and install four cover bolts (8) with
