23.3. Bearing of a forward nave

Check

Use of the indicator of hour type for measurement axial люфта the bearing of a nave of a forward wheel

PERFORMANCE ORDER
1. Tighten the parking brake, then lift a forward part of the car and fix on supports. Remove the corresponding forward wheel.
2. Screw in two bolts of fastening of a wheel with thick washers in openings from two opposite parties of a brake disk.
3. Using a drift or a screw-driver, remove a protective cap from the central part of a nave. If at removal of a cap there was its damage, it is necessary to replace it. At existence remove a spring located on an axis of a nave.
4. Using an edge big a flat screw-driver, being careful, take away brake shoes from a brake disk so that they did not interfere with nave rotation.
5. Fix an arm of the indicator of hour type on the forward party of a brake disk and establish a measuring tip of the indicator in an end face of a pin of a nave (see drawing). Establish a scale of the indicator of hour type on 0. Having undertaken from two parties a brake disk, move it along an axis. By indications of the indicator of hour type determine axial люфт the bearing of a forward nave. If axial люфт the bearing exceeds admissible value, it is necessary to make adjustment.
6. If axial люфт the bearing of a nave of a forward wheel is in admissible limits, remove from a brake disk the indicator of hour type, then establish a spring and a protective cap into place. Establish a wheel, then lower the car on the earth and tighten bolts of fastening of a wheel the demanded moment. Several times press a brake pedal in order that brake shoes contacted with a brake disk.

4. Using an edge big a flat screw-driver, being careful, take away brake shoes from a brake disk so that they did not interfere with nave rotation.
5. Weaken tightening a bolt holding a nut of fastening of a nave from unscrewing.
6. Rotating a brake disk, gradually tighten a nut of fastening of a nave until when the brake disk will be turned with insignificant effort. From this point unscrew a nut of fastening of a nave approximately on a turn third, then strike on a nave axis with a kiyanka to reduce a bearing tightness.
7. Using the indicator of hour type, measure axial люфт the nave bearing. If necessary make adjustment axial люфта the nave bearing, rotating a nut of fastening of a nave. After adjustment tighten tightening a bolt fixing a nut of fastening of a nave from unscrewing by the demanded moment of a tightening.
8. If axial люфт the bearing of a nave of a forward wheel is in admissible limits, remove from a brake disk the indicator of hour type, then establish a spring and a protective cap into place. Establish a wheel, then lower the car on the earth and tighten bolts of fastening of a wheel the demanded moment. Several times press a brake pedal in order that brake shoes contacted with a brake disk.
9. Repeatedly measure axial люфт the bearing of a nave of a forward wheel.
