Dismantling, assembly and installation of the steering mechanism

Check and adjust before disassembly

Replace the jaws plates of soft metal (brass or aluminum plate) to prevent damage to the steering mechanism and secure the latter in the grip (Fig. 5.36).

Checking the total torque pinion steering mechanism (preload shaft pinion steering)

To check the total torque pinion steering with a special key, rotate the gear rack and pinion steering mechanism within one revolution during a 4-6 (Fig. 5.37).

The total torque pinion steering (nominal value): 0.6-1.3 Nm.

If the measured value is not within the standard value, you must first adjust the position of the lid lock the rack and then check the total pinion torque steering.

If the total pinion torque can not be adjusted, check the cover of the stop, the spring stop and focus the rack and replace parts as needed.

Checking the resistance to rotation of the hinge of steering draft

Take turns 10 strong tie rod.

With the help of a spring balance to measure the resistance to the rotation of the hinge tie rod (Fig. 5.38).

Drag torque hinge of steering draft (nominal): 8-22 h (2-5 Nm).

If the measured value exceeds the standard value, replace the tie rod assembly.

As soon as the end of the retaining ring out of the groove housing the steering, turn the travel stop rack counter-clockwise and remove the retaining ring (Fig. 5.50).

Remove the O-ring with the bearing sleeve rail (Fig. 5.51).

Remove the gland bearing sleeve rail (Fig. 5.52).

Tapping with a plastic hammer striker gently remove the drive pinion and valve assembly from the valve body (Fig. 5.53).

Using a special tool, remove the oil seal and the ball bearing from the valve body.

Using a special tool, remove the seal from the housing of the steering mechanism (Fig. 5.54).

Checking the steering rack

Check for wear or damage to the teeth of the rack.

Check the contact surface for the installation of the gland in the absence of excessive wear or damage.

Check the straightness of the rack (no bending or twisting) (Fig. 5.55).

Check the O-ring for excessive wear or damage.

Check the oil seal in the absence of excessive wear or damage.

Check the teeth of the pinion for wear or damage (Fig. 5.56).

Check the contact surface for the installation of the gland in the absence of excessive wear or damage.

Check the O-ring for excessive wear or damage.

Check the oil seal in the absence of excessive wear or damage.

Check for smooth rotation and lack of background noise during operation of the bearings.

Check for excessive play in the bearings.

Check loss of needles from the needle bearing.

Check for damage on the inner surface of the cylinder housing of the steering mechanism.

Check the protective covers for wear, cracks and breaks.

Assembly

Apply the recommended hydraulic fluid PSF-3 on the lip gland steering rack along its entire circumference.

Set restrictive washer and gland in the body of the steering mechanism, as shown in Figure 5.57.

Apply the recommended hydraulic fluid to the oil seal bearing bush steering rack along its entire circumference.

Install the oil seal on the bearing sleeve rail (Fig. 5.58).

Apply the recommended hydraulic fluid to the O-ring and install it in the bearing bush steering rack.

Apply recommended grease to the teeth of the steering rack.

Recommended lubricant: SAE J310, NLGI ?��2 general purpose.

Insert the rail into the housing of the steering mechanism, and then install the bearing sleeve rail and rail travel stop (Fig. 5.60).

Insert circlip opening stroke limiter rail through the opening in the housing of the steering mechanism, when openings are aligned. Rotate the travel stop rails and finally fasten the retaining ring (Fig. 5.61).

Using a special tool, set the oil seal and the ball bearing into the valve body (Fig. 5.62).

Apply the recommended hydraulic fluid to the pinion gear and the valve assembly, then install them in the valve body (Fig. 5.63).

Apply the recommended hydraulic fluid to the gland, and install it in the body of the steering mechanism. Install the valve body assembly, and O-ring on the body of the steering mechanism (Fig. 5.64).

Install the new lock washer and the tie rod. Stake the edge of the lock washer in two places on the steering rod.

Before installation, always replace the new lock washer (Fig. 5.65).

Install the liner stop, a spring and a cover rail stop in the housing of the steering mechanism in the sequence shown in Figure 5.66.

Put into a "rubber" sealant (semydrying sealant) on the threaded portion of the lid lock rails before installing.

Set the rack in the center position, then insert the cover rail stop in the housing of the steering mechanism. Using a special tool, tighten the lid stop rail to 15 N ?� m (Fig. 5.67).

Remove the lid all the way to 30-60 ?� rail and tighten the lock nut caps lock rails rated torque of 50-70 Nm.

Install and tighten the mounting tubes of the steering mechanism to the specified torque, then replace the rubber feet using a special glue (adhesive).
