Separately purchased hydraulic connecting rod/main bearing-caps cap screw torquing tool is required to achieve the additional 60° turn on the cap screws, see Figure 7-12 on page 7-7. b. See Page 5-6 for complete instructions. Separately purchased hydraulic connecting rod/main bearingcaps cap screw torquing tool is required to achieve the additional 110° turn on the cap screws, see Figure 7-12 on page 7-7. c. Use 8700 psig (600 bar g ) hydraulic pressure and 30 lb-ft (41 N·m) tightening torque on separately purchased piston rod tensioning tool G-12644. Tighten, loosen and re-tighten piston nut to be sure of proper tightening. See “Piston and Rod - Reassembly” on page 5-37. See “Ariel Tools - Separately Purchased” on page 7-4. PAGE 1 - 20 7/09

FOR MODELS: JGZ AND JGU SECTION 1 - DESIGN SPECIFICATIONS & DATA d. Use 2000 psig (138 bar g ) hydraulic pressure on separately purchased crosshead (balance) nut torquing tool G-12645. e. Minimum torque for recommended 1-3/4 in. – 5 TPI hold-down stud size to provide stress in stud of 55,000 psi (380 MPa). Stud must have an ultimate strength of 100,000 psi (690 MPa) or greater. If greater, increase torque, to stress stud to about 55% of the ultimate strength of the stud material, as specified by packager. Or use separately purchased hydraulic hold-down stud tensioner tool (G-12860). See Figure 7-13 on page 7-8. f. When studs are specified for cylinder applications, tighten stud-nuts to the same values as cap screws in similar applications.
