|
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. 5.42). 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. 5.43). 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 to the oil seal lip steering rack along its entire circumference. Recommended fluid: PSF-3.
| Fig. 5.44. Install the gland into the housing of the steering mechanism
|
With a special tool (09431-11000), install the seal into the housing of the steering mechanism, as shown in Figure 5.44.
ATTENTION Note the direction of the lip seal. Use only a new oil seal. |
Apply the recommended hydraulic fluid to the oil seal bearing bush steering rack along its entire circumference. Recommended fluid: PSF-3 Install the oil seal on the bearing sleeve rail.
Apply the recommended hydraulic fluid to the O-ring and install it in the bearing bush steering rack with a special tool (09431-11000) (Fig. 5.45). Apply recommended grease to the teeth of the steering rack.

| Fig. 5.47. Installation of the bearing sleeve and rail travel stop rail
|
Insert the rail into the housing of the steering mechanism, and then install the bearing sleeve rail and rail travel stop (Fig. 5.47). 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 snap ring.
ATTENTION After installation, the ends of the locking ring should not be visible through a hole in the hull of the steering mechanism (Fig. 5.48). |
Apply the recommended hydraulic fluid and the recommended grease to the pinion gear and the valve assembly and place it into the housing of the steering mechanism (Fig. 5.49). Recommended fluid: PSF-3. Recommended lubricant: SAE J310a, NLGI ?��2 general purpose.

|
Install the ball bearing with a special tool (09222-21100) (Fig. 5.50). Set pinion and valve assembly into the valve body.
Install the oil seal with a special tool (09432-21601) (Fig. 5.51). Install the snap ring using the snap ring pliers.
Turn the drive pinion clockwise until it stops and tighten the self-locking nut (Fig. 5.52).
ATTENTION Always replace a new self-locking nut. |
Put into a "rubber" sealant (semydrying sealant) on the threaded portion of the plug and tighten to the specified torque (Fig. 5.53). Tightening torque cap: 50-70 Nm. Tighten cap in two places by the core.
Install the new lock washer and the tie rod. Stake the edge of the lock washer in two places on the steering draft (Fig. 5.54).

| Fig. 5.55. The sequence of installation of the components in the housing of the steering mechanism
|
Install the liner, rail fence, spring lock rack and cover rail stop in the housing of the steering mechanism in the sequence shown in Figure 5.55. 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 cap rail stop torque of 20-25 Nm. Remove the cover rail stop about 20 degrees and tighten the lock nut caps lock rails rated torque. Tightening torque lock nut: 50-70 Nm. After adjustment, replace the cover stops rack with a lock nut.
ATTENTION If within the specified value of the angle of rotation to adjust the torque of the pinion gear does not work, check or replace parts and caps lock rail stop rail. |
Install and tighten the mounting tubes of the steering mechanism to the specified torque, then replace the rubber feet using a special glue (adhesive). Apply recommended grease to the place of installation of small clamp on the protective cover of steering draft (in the groove on the traction). Recommended lubricant: SAE J310a, NLGI ?��2 general purpose. Install a new high collar of a protective cover of steering draft.
NOTE Before installing a protective cover of steering draft is always replaced with the new high collar of a protective cover. |
