Assembly Procedure for SWQ Couplings
After ensuring that the equipment is aligned properly, follow the instructions below for assembly. For SWQ Couplings, take the spacer jaw body assembly with the inside & outside rings without elastomeric elements. Insert spacer assembly in the steps provided in the adapters. Tighten the bolts with the recommended torque. Wrap the snap wrap(s)/insert cushions of required size in the space between jaws. Then slide the outer ring over the snap wrap(s)/cushions accordingly and fix it to the hub with the help of screws/bolts along with the washers.
