INSPECTIONM37SCM
TIR ROD SWING TORQUE INSPECTION
(1) Swing the tie rod ten times hard.
(2) Point the tie rod end down, then attach a spring balance as
shown in the illustration to measure swing resistance
(swing torque).
Standard value: 9
- 55 N (2 - 12 Ibs.)
[0.5 - 3 Nm (4 - 26 in.lbs.)l(3) If the swing resistance exceeds the standard value, replace
the tie rod.
(4) If the swing resistance is less than the standard value, the
ball joint may be reused as long as it is not loose and
operates smoothly.
POWER CYLINDER SLIDE RESISTANCE CHECK
(1) Place the piston in a neutral position.
(2) Wrap a wire around the tie rod end, then measure slide
resistance with a spring balance as shown in the illustration.
Standard value: 67 N (15
Ibs.) or less
(3) If the slide resistance exceeds the standard value,
replace,the power cylinder.
(4) If the slide resistance is less than the standard value, the
power cylinder may be reused as long as it is not loose and
slides smoothly.
