GENERAL / Tightening Precautions for Spilt Flange IMPORTANT: 1. Clean the sealing surfaces. Check if the scratches / roughness that cause leaks and damage of O-ring are found. 2. Use only specified O-rings. Inspect O-rings for any damage. Do not file the O-ring surfaces. When installing O-ring into a groove, use grease in order to hold O-ring in place. 3. While tightening the bolt by hand, check that flange is installed to the port correctly. Do not pinch the O-ring. 4. Tighten the bolts alternately and diagonally, in order to ensure even tightening to the specified torque. 5. Do not use air wrenches.
Using an air wrench often causes tightening of one bolt fully before tighten the others, resulting in damage to O-rings or uneven tightening of bolts. Nut and Bolt Locking Lock Plate IMPORTANT: Do not reuse the lock plates. Do not try to bend the same point twice. Split Pin IMPORTANT: Do not align the holes in the bolt and nut while loosening. Tighten and align anytime. Do not reuse the cotter pins. Wire IMPORTANT: Attach a wire to bolts in the bolt-tightening direction. Do not reuse the wire.
