11.3.5. Replacement of bearings of back wheels
|
|
- Block forward wheels, then поддомкратьте a back of the car and reliably establish it on axial support. Disconnect the external hinge of equal angular speeds from a drive flange (see. Head Transmission line). Support the external end of a power shaft a piece of a wire - do not allow it to hang, since it can damage the internal hinge of equal angular speeds.
|
|
- Take a lock level which holds a nut of a flange of a drive. Having hooked the lever edge of a lock level, pull out it by means of pair of nippers.
|
|
|
- Lower the car on the earth and release a nut of a flange of a drive, but yet do not remove it. You will need a long breakage.
|
|
|
Do not try to release this nut when the car costs on axial support. The effort necessary for holiday of this nut, can fall down the car from support. |
- Release bolts of fastening of back wheels, again поддомкратьте a car back, reliably establish it on axial support and remove a wheel.
- Remove a brake support and a brake disk (see. Head Brake system). Suspend a support on a piece to a wire that it did not disturb work.
|
|
- Give a nut of a flange of a drive. By means of a suitable stripper remove a drive flange.
|
|
|
- By means of a kiyanka beat out a rotary pin from the bearing. If the internal holder of the bearing acts in film together with a rotary pin (such often happens), use a stripper to remove a holder from a pin. If she does not act in film even a stripper, carry a pin in a workshop and выпрессуйте it from a holder.
|
|
|
- Take the big lock ring holding the bearing to its case.
|
|
|
... then by means of a big replaceable head or a suitable piece of a pipe pull out the bearing from the case.
|
- Installation generally repeats removal procedure upside-down, but remember the following:
|
|
- Establish the new bearing by means of a big replaceable head or a suitable piece of a pipe with the external diameter corresponding to diameter of an external holder of the bearing. Do not press an internal holder. Make sure that the bearing rose on the place against the stop. Establish a lock ring and be convinced that it correctly costs in a flute
|
|
|
- Dealers of BMW use special adaptations (No. No. 23 1 1300, 33 4 080 and 33 4 020) for installation of a rotary pin in the bearing since the smooth piece of a rotary pin between a flange and its shlitsevy piece usually впрессован and beats out an internal holder of the bearing at pin installation. You, however, can establish a pin and without these adaptations, using only an old internal holder and a piece of a pipe in length of 13 mm with internal diameter of 38 mm.
|
|
|
- At first insert a rotary pin into the new bearing so that the piece with a carving seemed from an internal holder. Get a nut and tighten it while shlitsevy the piece of a pin will not rest against a nut. You should hold a pin flange the lever or a big screw-driver during a nut tightening.
|
|
|
- Give a nut, establish your piece of a pipe centered on an internal holder, get a nut and again tighten it while it will not rest in a shlitsa.
|
- Remove a nut, establish an old internal holder, get a nut and again tighten it against the stop in a shlitsa. Give a nut, remove an old holder, establish a piece of a pipe, again establish an old holder, get a nut and tighten it against the stop in a shlitsa. Remove a nut, an old holder and a pipe. Establish a drive flange, get a nut and reliably tighten it, but do not try to tighten it up to the end while the car is not lowered on the earth.
- Establish a wheel and lower the car on the earth before tightening a nut of a rotary pin with demanded effort.
- Other part of installation is made as it should be, the return to removal.
