ARIEL BOLTING

REQUIRED TIGHTENING TORQUECAUTION

Bolting has been selected that will meet the strength, elongation, locking features and mechanical clearance required. The

proper bolting must be used and tightened to the torque values listed. Threads are to be clean and free of burrs. Use

petroleum lubricating oil or Lubriplate 630 on threads and seating surfaces, except for compressor piston rod-piston nuts

crosshead nuts; JGB/JGV main bearing cap stud-nuts; and JGS exhaust elbow to cylinder head cap screws use Never

Seez, and except where Loctite is specified. These torque values are for current production equipment, for older units

which have lower torque values specified do not assume higher values without consulting packager and/or Ariel.
