    INTRODUCTION Torque Bolt types NOTICE: Use tools appropriate for the work to be done. Makeshift tools and procedures can create safety haz- ards. For loosening and tightening nuts and bolts, use the correct tools. Avoid bodily injury caused by slipping wrenches.
  • Page 22 INTRODUCTION Bolt tightening order When tightening two or more bolts, tighten them alternately, as shown, to ensure even tightening. SMIL13CEX0149EA A Equally tighten upper and lower alternately B Tighten diagonally C Tighten from center and diagonally 48005326 27/04/2016...
  • Page 23 INTRODUCTION Service recommendations for split flange 1. Be sure to clean and inspect sealing surfaces. Scratches/roughness cause leaks and seal wear. Unevenness causes seal extrusion. If defects cannot be polished out, replace the component. 2. Be sure to use only specified O-rings. Inspect O-rings for any damage.
  • Page 24 INTRODUCTION Nut and bolt lockings Lock plate NOTICE: Do not reuse lock plates. Do not try to bend the same point twice. Cotter pin NOTICE: Do not reuse cotter pins. Match the holes in the bolt and nut while tightening, not while loosening. Lock wire NOTICE: Apply wire to bolts in the bolt tightening direc- tion, not in the bolt-loosening direction.
