Power Steering Gear And Linkage: Disassembly

  1. Prior to disassembling, measure pinion rotating torque using Tools.
    • Tool numbers: KV48101100 (J26364) 
      • ST3127S000 (25765-A) 
    • Within +/-100° from the neutral position 
    • Average rotating torque: 0.6 - 2.0 N.m (7 - 20 kg-cm, 6 - 17 in-lb) 
    • Maximum torque deviation: 0.5 N.m (7 kg-cm, 5.8 in-lb) 
    • Except for above measuring range 
    • Maximum rotating torque: 1.9 N.m (19 kg-cm, 17 in-lb) 
    • Maximum torque deviation: 0.65 N.m (7 kg-cm, 6 in-lb)
