12.5. Rotary fist and nave of a forward wheel

Removal

Before removal of power shafts close towels all sharp sides about power shafts that will provide protection of covers against damages.

At removal of a power shaft be careful not to stretch the hinge of equal angular speeds as at the same time there can be a separation of internal elements of the hinge and to its possible damage. The CV JOINT and a protective cover have to be reliably protected when working with power shafts or about them.


 PERFORMANCE ORDER

  1. Remove a forward wheel.
  1. Remove the forelock, turn off a koronchaty nut and remove a washer of fastening of a power shaft to a nave of a forward wheel.
  1. Take the forelock and turn off a nut of fastening of a pin of the spherical hinge of a tip of steering thirst for a rotary fist. A stripper 09568–34000 squeeze out a pin of the spherical hinge from a rotary fist.

Fix by a cord a stripper for the closest element of the car.

  1. Remove a support and fix by a soft wire it on a forward rack.
  1. Measure by the indicator of hour type a beating and an axial gap of a nave of a forward wheel.
  1. Stripper 09568–34000 disconnect the spherical hinge of the lower lever from a rotary fist.
  1. Remove the rotation frequency sensor from a rotary fist.
  1. Note situation and turn out bolts of fastening of the lower part of a rack of a forward suspension bracket to a rotary fist.
  2. The kapron hammer beat out a power shaft from a nave of a forward wheel. If the power shaft densely sits in a nave of a forward wheel, spray impregnating aerosol solvent on area of shlits and then repeatedly screw a nut with a fillet so that it settled down flush with a shaft end face. Striking a nut with the brass hammer, beat out a power shaft from a nave.
  3. Remove a rotary fist together with a nave of a forward wheel.

Dismantling

 PERFORMANCE ORDER

  1. Turn out two screws and remove a brake disk from a nave of a forward wheel.
  1. Remove a lock spring ring.
  1. Install special tools 09517-29000, 09517-21500, as shown in the drawing.
  1. Turning the special tool, remove a nave of a forward wheel from a rotary fist.
  2. Remove the special tool and a dustproof ring.
  1. The special tool 09495-33000, 09551-31000 remove an internal ring of the bearing from a nave.
  1. The special tool 09495 – 33100, 09517–29000 remove an external ring of the bearing from a rotary fist.

Check

 PERFORMANCE ORDER

  1. Check a nave for lack of cracks and wear.
  2. Check a brake disk for lack of development and damages.
  3. Check a rotary fist for lack of cracks.
  4. Check the bearing for lack of cracks or damages.

Assembly

 PERFORMANCE ORDER

  1. Apply a thin film of jellied lubricant in an opening of a rotary fist and on an external ring of the bearing.
  1. Press with a mandrel 09495–33100 corresponding diameters press the new bearing of a wheel.
  • Do not make effort of a press for an internal ring of the bearing.
  • At installation always use the new bearing.
  1. Establish a spring ring in a groove of a rotary fist.
  2. Establish a dustproof ring.

  1. Press with a mandrel 09495–33100 corresponding diameters press a nave in the wheel bearing.

Do not make effort of a press for an external ring of the bearing.

  1. Establish a brake board.
  1. The special tool 09517-21500 tighten a nave to a rotary fist, having tightened adaptation bolt the moment of 200-260 N • m.
  1. Several times turn a nave that elements of the bearing were established on the places.
  1. Measure torque which needs to be put for a bearing provorachivaniye. Torque: no more than 1,8 N • m.
  1. If torque of 0 N • m, measure an axial side play of the hug bearing.
  1. If the torque exceeds the required value, so the bearing is incorrectly installed in a rotary fist and on a nave. Sort a rotary fist and repeatedly collect it. Axial side play of the bearing: no more than 0,008 mm.
  1. Remove the special tool 09517-21500.
  2. Establish a brake disk and fix it by screws.

Installation

 PERFORMANCE ORDER

  1. Installation is carried out to the sequences, the return to removal.

Tighten threaded connections the required moments in the following order:

Nut of fastening of a power shaft: 200–260 N • m
Nut of fastening of a pin of the spherical hinge of the lower lever to a rotary fist: 60–72 N • m
Nut of fastening of a rotary fist to stoyke:130-150 N • m

  1. Establish a rack and a power shaft in a rotary fist.
  2. Connect the ABS sensor.
  3. Establish a support.
  4. Tighten a nut of fastening of a pin of the spherical hinge of the lower lever to a rotary fist.
  5. Tighten a nut of fastening of a pin of the spherical hinge of a tip of steering thirst for a rotary fist and record it a pin.
  6. Establish a washer and tighten a koronchaty nut.
  1. Install the forelock.
  1. Establish a wheel.
