4.17. Replacement of the forward bearing of a primary shaft of a transmission

The forward bearing of a primary shaft of a transmission functionally concerns transmission and plays a role of a forward support of a shaft. But this bearing is located in a nest of a cranked shaft of the engine, therefore its replacement is described in the given section.

At deterioration or jamming of this bearing because of a greasing lack there is an effect of "conducting" coupling – the complicated gear change.

It be required to you: a special pusher of the bearing (at absence take advantage of make-shifts: greasing Litol-24 and sawdust), a hammer, a screw-driver.

On sale there is a considerable quantity of strippers for выпрессовки this bearing (inertial, цанговые, etc.). However not always they are had near at hand. The offered way with use of make-shifts in most cases leads to demanded result, as bearing landing in a nest of a cranked shaft rather weak.

1. Remove from the car a transmission and coupling (section 5 "Transmission" see).

2. Remove a flywheel (Removal, installation and дефектовка a flywheel »see«).

3. Prepare for выпрессовки the bearing a mix in a volume parity 1:1 from greasing Litol-24 and sawdust, having mixed them before reception of a homogeneous mix.

THE NOTE Mix volume – not less polyethylene cover from a 3-litre jar filled completely.

4. Fill with a mix an internal cavity behind the bearing.	5. Оправкой for a centering of a conducted disk выпрессовывайте the bearing, periodically adding a mix in process of a bearing exit...

6.... To its full exit from a nest.

THE PREVENTION After application of the specified method the bearing is not suitable to the further use and is subject to obligatory replacement.

7. Clear a nest of the bearing of a mix.

8. Through approaching on external diameter of the bearing the mandrel запрессуйте the bearing against the stop.

THE PREVENTION It is inadmissible запрессовывать the bearing, putting effort to an internal ring. In this case the bearing will be inevitably damaged.

9. Establish the removed details and knots in an order, the return to removal.
