Charging dimensions for a suspension cylinder which has been purged Charge with oil ... 25.4 mm (1.00 inch) Full charge of oil and nitrogen ... 170.0 mm (6.69 inch)Note: Use FT1680 Gauge Block in order to achieve the dimension for the full charge of oil and nitrogen. See Testing and Adjusting, "Suspension Cylinder (Front) - Purge and Charge" for the charging procedure. (1) Torque for the 20 nuts ... 940 35 N m (693 26 lb ft) (2) Shim ... 4.47 0.08 mm (0.176 0.003 inch)Note: See the steering system Testing and Adjusting, "Front Axle - Install and Adjust" in order to determine the thickness that should be installed.
Personal injury or death can result when working with the strut rod.Sudden release of the spindle from the strut rod or the snapping of a bolt when removing the plate can result in injury.Loosen all bolts one-half turn, working around the plate in a circular pattern. Perform this again and again until the torque is released for the bolts.
(3) Final torque for eight bolts ... 680 35 N m (502 26 lb ft)Note: Perform the steering system Testing and Adjusting, "Front Axle - Install and Adjust" before you install these bolts. (4) Valve assembly Torque for the charging valve ... 14 1 N m (10.3 0.7 lb ft) Torque for the valve cap ... 7 1 N m (62 9 lb in) (5) Torques for 30 bolts Static inspection torque for 30 bolts ... 60 N m (44 lb ft) Assembly torque for 30 bolts ... 135 20 N m (100 15 lb ft) (6) Apply 8T-9014 Silicon Sealant prior to assembly. (7) Torque for the ten bolts ... 135 20 N m (100 15 lb ft) (8) Outside diameter of piston (two lands) ... 201.17 0.13 mm (7.920 0.005 inch) (9) Inside diameter of the tube ... 203.25 0.13 mm (8.002 0.005 inch) (10) Inside diameter of gland (three places) ... 178.18 0.03 mm (7.015 0.001 inch) (11) Outside diameter of rod ... 177.72 0.05 mm (6.997 0.002 inch) (12) Fill the lower cavity with 7X-7664 Grease after assembly. (13) Apply a coat of 4C-5593 Anti-Seize Compound before assembly with the spindle.Note: Approximately 13.8 L (3.6 US gal) of SAE 10W oil with the current service classification is necessary in order to charge a cylinder.Note: If the front suspension cylinder is disassembled, reassemble the cylinder only in the vertical position.The charging medium for suspension cylinder is dry nitrogen.Internal volume ... 5.937 L (362 in3)Charged pressure ... 1200 kPa (175 psi)Service pressure ... 3500 kPa (500 psi)Bursting pressure ... 35000 kPa (5075 psi)Charged safety factor ratio ... 29:1Service safety factor ratio ... 10.2:1
