4.3.3. Dismantling and assembly of a nave of a forward wheel assembled
Check of a technical condition
Check a nave condition, having paid attention to cracks and wear of a shlitsevy surface.
Check a condition of a rotary fist, having paid attention to cracks.
Check a technical condition of the bearing.
|
ATTENTION
In case of education люфта between an external ring of the bearing and a rotary fist or an internal ring of the bearing and a nave replace the bearing or the damaged elements.
|
Nave removal
|
ATTENTION
In case of nave removal surely replace a podshmpnik of a nave on new as at nave removal on a surface of a friction of the bearing damages are formed.
|
To remove a nave from a rotary fist, use the following special tool.
The adaptation for removal of a nave and the wheel bearing (МВ991056 илиМВ991355).
The adaptation for removal and installation of a nave of a forward wheel (МВ991017).
Rasporny plug (МВ991000).
Removal of the bearing of a nave
Crush an epiploon in two places so that pads special инструмета could grasp (from the outer side) an internal ring of the bearing of a nave.
|
ATTENTION
During removal (from the outer side) an internal ring of the wheel bearing be careful not to drop a nave.
|
Remove from a nave (from the outer side) an internal ring of the bearing of a nave, having used a stripper of bearings (МВ990810).
Establish on the nave bearing (from the outer side) an internal ring which was removed from a nave. Remove the wheel bearing, having used the special tool listed below. Handle (МВ990938). Opravka (МВ990935). The adaptation for removal of a nave and the nave bearing (МВ991056 or МВ991355).
Installation of the bearing of a nave
Grease the nave bearing with konsistentny greasing.
Put with a thin layer konsistentny greasing on contact surfaces of a rotary fist and the bearing.
|
ATTENTION
During a press fitting of the bearing of a nave put effort to an external ring. Otherwise the podshinik will be damaged.
|
Press the bearing by means of listed below the special tool.
Opravka for installation of saylent-blocks of a back suspension bracket (МВ990883).
The basis for installation of saylent-blocks of a back suspension bracket (МВ990890).
Check of the moment of forces of a friction on a nave
Fix a bolt and tighten a nut.
Tighten the special tool listed below the every moment and then запрссуйте a nave in a rotary fist.
The adaptation for removal and installation of a nave of a forward wheel (МВ991017).
Rasporny plug (МВ991000).
Turn a nave that the bearing occupied the situation.
Having used the special tool listed below, measure on a nave the moment of forces of a friction.
Dinamometrichesky key (МВ990685)
Special head (МВ990326)
Admissible value: 1,8 N · m.
The size of the moment of forces of a friction should not exceed admissible value, and rotation of a nave should be smooth.
Check axial люфта nave bearing
Having used the special tool listed below, measure axial люфт the bearing of a nave and check, whether соотвтествует it to admissible value.
The adaptation for removal and installation of a nave of a forward wheel (МВ991017)
Rasporny plug (МВ991000)
Admissible value: 0,05 mm.
If the nut is tightened the every moment of 245 ± 29 N · m, and axial люфт exceeds admissible value, the wrong installation of the bearing, a nave and/or a rotary fist can be the possible reason of it. Replace the bearing of a nave and establish it again.
Check of a technical condition
Check a condition of an internal surface of a rotary fist, having paid attention to wear and cracks.
Check a condition landing поврехностеи a nave and a brake disk of a forward wheel, having paid attention to wear and pollution.
