23.4. Nave of a forward wheel
Prevention
The hug bearing of a forward wheel is pressed in a rotary fist therefore at removal there is a high probability of its damage and, perhaps, its replacement will be required.
Nave of a forward wheel
Removal
Use of the screw-driver for removal of a protective cap from a nave of a forward wheel
Removal of a spring from a nave axis
Weakening of the tightening bolt fixing a nut of a nave of a forward wheel
Unscrewing of a nut of fastening of a nave of a forward wheel
Repair
PERFORMANCE ORDER |
1. Take an internal ring of the external bearing from a nave. |
2. Remove a sealing ring from a back part of naves and then take an internal ring of the internal bearing. |
3. Establish a nave on the corresponding mandrel and, using the hammer and a drift, beat out an internal ring of the external bearing. At the same time do not warp a ring not to damage a bearing nest in a nave. |
4. Turn a nave and similarly beat out an external ring of the internal bearing. |
5. Clear a nave of dirt and lubricant and, using an emery paper, polish agnails on a nave. Check a condition of a nave for existence of cracks, wear and mechanical damages and, if necessary, replace. On models with anti-blocking system check a condition of a gear rotor of the sensor. |
6. Before assembly apply a thin film of lubricant on an external ring of the bearing and the interfaced nave surface. Also grease racetracks of an internal ring. |
7. Establish a nave on a mandrel and establish an external ring of the internal bearing in a nave. Using the tubular mandrel leaning on an external ring of the bearing, and a press press a bearing ring in a nave against the stop. At a press fitting do not warp a bearing ring. |
8. Turn a nave and similarly press an external ring of the external bearing in a nave. |
9. Establish an internal ring of the internal bearing. On a back part of a nave establish a sealing ring by working edges to the bearing. Fill bearings with the lubricant making two thirds of full volume of lubricant, then establish an internal ring of the external bearing. |

Installation
PERFORMANCE ORDER |
1. Apply a thin film of lubricant on a back part of a sealing ring of a nave and establish a nave on a pin of a rotary fist. |
2. Establish a persistent washer and screw a nut of fastening of a nave. |
3. Putting the clamp of fastening of a nave, press internal rings of the hug bearing on a pin of a rotary fist. After installation of a nave adjust an axial side play of the hug bearing. After carrying out adjustment tighten tightening the bolt fixing a nut of fastening of a nave from unscrewing. |
4. Establish a spring on a pin of a rotary fist. |
5. Establish on a nave a protective cap with lubricant. |
6. Establish a brake disk and, in the presence, the sensor of a forward wheel of anti-blocking system of brakes. |
