Adjusting Cover, Locknut (Adjusting Cover) Assembly Note
- Apply screw locking agent to the screw area of the adjusting cover, and assemble to the gear housing.
- Tighten the adjusting cover with a tightening torque of 20-29 N.m {2.1-2.9 kgf.m, 15-21 ft.lbf} and then loosen.
- Tighten the adjusting cover again with a tightening torque of 5.9 N.m {60 kgf.cm, 52 in.lbf} .
- Return the adjusting cover to 10-20° using the SST .
- Combine the SST
with the torque wrench, then measure A and L as shown in the figure.
- A: Length from the center of the locknut to the grip.
- L: Length of the torque wrench.
- Recalculate the torque by using torque formulas, then lock the adjusting cover against rotation and tighten the locknut (adjusting cover) using the SST
.
CAUTION:
- If a tool is installed to the SST (49 E032 308), install it perpendicular as shown in the figure. If it is installed incorrectly, the SST will readily come off the locknut which could result in damage to the locknut during the servicing.
Tightening torque
- 20-29 N.m {2.1-2.9 kgf.m, 15-21 ft.lbf}
TIGHTENING TORQUE SPECIFICATIONTorque unit Formula N.m N.mx[L/A] kgf.m kgf.mx[L/A] ft.lbf ft.lbfx[L/A] - Measure the rotational torque of the pinion shaft using the SST
and a pull scale.
Pinion shaft rotation torque
- Center of rack ±90°: 1.4-1.8 N.m {15-18 kgf.cm, 13-15 in.lbf}
- [Pull scale reading: 14-18 N {1.5-1.8 kgf, 3.2-4.0 lbf}
- Except center of rack ±90°: 2.1 N.m {21 kgf.cm, 19 in.lbf} or less
- [Pull scale reading: 21 N {2.1 kgf, 4.7 lbf} or less
- If it is not within the specification, remove the locknut and loosen the adjusting cover, and then repeat Steps 2 to 6.
