It is recommended that the swivel be removed from the supporting loading arm prior to any seal maintenance. All torsion spring pre-load must be removed from torsion-spring prior to any swivel joint disassembly. Step 6: Align flange with body and press surfaces together. Thread flange bolts with Nord-Lok™ washers into tail and torque to amount shown on chart. Nord-Lok™ washers come as an assembly bonded together from the factory. It is important that the correct orientation be preserved for proper function. Step 2: Remove all split flange bolts on the side of the swivel attached to the free-moving end. With the bolts loosened, support this side of the loading arm along with any other parts attached to it that might move freely when the bolts are removed. Remove bolts, starting with lowest on flange, leaving top bolts for last. Be careful not to damage sealing flange module face and bolts. There are two different serration patterns on each side of the washer, with two washers in an assemb The coarser serrations must face inward and | Step 3: Once the now-detached arm has been secured and put out of the way, remove the three (3) O-rings and two (2) O-ring spacers. Inspect and cle: machined surfaces to that there are no nick scratches or Step 7: Press static seal into swivel body outer groove, followed by placing purge seal inside recess created by tail and body. Set seal spacer ring inside purge seal, followed by main seal. Set SST smooth-bore ring inside main seal, then cap entire seal/spacer combination with sealing flange. Torque bolts to specified value.
