Gear Coupling Installation Instructions

1. Mount Flanged Sleeves, Seals & Hubs

Clean all parts. Grease the crowned gear teeth and O-Ring. Put O-Ring onto the shafts. Place the flanged sleeves with seal rings on the shafts, and mount the hubs on their respective shafts. Seal keyways to prevent leakage. Insert setscrews and tighten. Position the equipment in approximate alignment with hub gap as in Table 1.

2. Gap & Angular Alignment

Use a spacer bar equal in thickness to the gap specified in Table 1. Insert bar to the same depth at 90° intervals and measure clearance between bar and hub face with feelers.

3. Offset Alignment

Align the shaft with a straight bar, checking every 90°, referring to Table 1. Check with feelers. Make sure with a dial gauge to not exceed the offset limit.

4. Assemble Coupling

Insert gasket between the flanges and fasten the bolts, positioning the lube hole at 90°. Tighten fasteners to the torque specified in Table 1.

5. Large Size (over size 70)

Install the coupling as above. Remove all lube plugs and put recommended grease into the coupling until excess flows through an opened lube hole, then plug. Fill the grease until overflowing at the opened opposite hole.
