Removal
PERFORMANCE ORDER
1. To disconnect from the accumulator a weight wire.
2. To remove the handle of the lever of a gear change.
3. To remove (depending on the equipment version) the average console or a shelf about the gear change lever.
4. To remove an external casing of the lever of a gear change after its detachment from the holder, and also an internal casing with the holder after unscrewing of a framework of the holder from the floor tunnel.
5. To unscrew the lever of a gear change from a back part картера transmissions.
6. To prop up a coupling pedal.
7. In an engine compartment to remove forward left and right acoustic isolation.
8. To remove the top casing of a radiator.
9. To unscrew the top bolt of fastening of a starter and to disconnect a weight wire.
10. To prop up the engine a jack.
11. Under the car to remove the bottom acoustic casing of the engine.
12. To disconnect a metallo-rubber connector from a longitudinal beam.
13. To disconnect a forward reception pipe from a final collector, having unscrewed nuts of its fastening.
14. To disconnect propeller a shaft from a flange of a leading gear wheel of the main transfer, holding hairpins with tool Torx that they were not unscrewed from a flange of the main transfer at unscrewing of nuts of fastening of a shaft, and also to disconnect the average bearing карданного a shaft from a body arm.
15. To disconnect the spherical hinge карданного a shaft from a flange of a transmission and to take propeller a shaft.
16. To prop up a transmission by means of wooden брусков.
17. To remove the holder of a suspension bracket of a transmission.
18. To lower a transmission.
19. To lower the engine. Its head of the block of cylinders should not contact to brake pipelines thus. In case of need it is possible to establish wooden брусок between a head of the block of cylinders and a face-to-face partition.
20. To disconnect the external mechanism of a gear change.
21. To disconnect a cable of a speedometer and a wire from the switch of fires of a backing.
22. To take spring защедку and to disconnect a cable of coupling from plugs of deenergizing of coupling.
23. To remove a sheet partition картера the couplings, located between the block of cylinders of the engine and a transmission.
24. To unscrew the remained two bolts of fastening of a starter and to remove a starter.
25. To unscrew 3 bolts of fastening картера couplings to the block of cylinders of the engine.
26. To disconnect a transmission from the engine and to take it from below the car.

Installation

PERFORMANCE ORDER
1. To delay plugs of deenergizing of coupling back and to fix their wire in this position.
2. To cover with a thin layer of special greasing Ford (N 5021439) шлицы a primary shaft.
3. To attach a transmission to the block of cylinders of the engine (3 bolts).
4. To insert into apertures two bolts of fastening of a starter.
5. To establish a sheet partition between the block of cylinders of the engine and картером boxes.
6. To tighten bolts of fastening of a sheet partition.
7. Then to execute actions in return sequence in relation to process of removal of a transmission, paying attention on:
       – Observance of the necessary moments of a tightening of carving connections;
       – Transmission filling by necessary quantity of corresponding oil;
       – Check of tightness of a transmission.

The prevention

Before installation of the rubber elastic hinge карданного a shaft on a transmission flange it is necessary to check up, whether hairpins on a flange are correctly fixed. In case of detection that hairpins are turned, them it is necessary to unscrew, clear their carving, to put on a site of the carving which are screwed in in a flange, two drops of the means protecting from unscrewing (for example, Loctite 270) to tighten these bolts in 5 minutes the moment of 80 Nanometers and to wait for 30 minutes for preservative hardening.
