9.1.3. Replacement of epiploons
The worn-out or damaged epiploons will lead to leaks. The lack of lubricant of transmission can cause hard gear shifting, unauthorized switching switching off of transfer and noise of transmission. As a result, this lack of lubricant will result in the accelerated wear and failure of components.
All three epiploons of transmission can be replaced without dismantling of transmission; two of them can be replaced even without removal of transmission.
If in an epiploon leak is supposed, then, working under transmission, attentively examine epiploons. Establish it on supports. For prevention of an otkatyvaniye of the car do not forget to establish an emphasis under back wheels.
Do not confuse leak of motive oil with leakages of transmission - gipoidny oil, for example, has a peculiar smell, and on it it can be easy отличимо from motive. If oil covers a forward part of the driveshaft, then either the epiploon of a shaft of the switch, or an epiploon of an output shaft proceeds. If oil is revealed on the coupling case bottom, then, probably, the epiploon of an entrance shaft proceeds (of course, the back epiploon of a bent shaft can also cause existence in the lower part of a case of coupling of motive oil). Every time having made the decision on replacement of an epiploon, first of all check ventilating the device in the top part of a case of transmission. The corked or damaged ventilating device can lead to increase in pressure transmission, and that oil will be squeezed out through epiploons. If just to replace an epiploon without clearing of the corked ventilating device, the new epiploon soon will also lead to refusal.
Epiploon of an output shaft

- Lift a front of the car and establish it on supports. For prevention of an otkatyvaniye of the car do not forget to establish an emphasis under back wheels.
- If it is necessary for ensuring access, remove system of release (watch Chapter the Power supply system).
- Remove the driveshaft (watch Chapter the Transmission line). If measures against creation of load of cardan hinges are taken, then the driveshaft can be not disconnected from the back bridge.
- Unbend ledges of a lock plate from their flutes and remove a lock plate. Holding a flange (if it is necessary, fix by a bolt a long plate), a face head of 30 mm with thin walls turn off a flange nut. Remove a flange from an output shaft. If necessary apply a stripper.
|
|
- The tool for removal of epiploons or the small screw-driver carefully pick up an old epiploon. Make sure that at extraction of an epiploon of deepening under an epiploon it will not be damaged.
|
- Apply a thin film of lubricant on a fillet of a new epiploon and clear the end of an output shaft. Put on an epiploon a shaft and slightly less outer diameter of an epiploon establish by carefully short piece of a pipe with outer diameter an epiploon into place.
- Establish a flange. For prevention of leaks apply sealant on the party of a nut turned to a flange. Tighten a flange nut with the effort specified in the Size table and adjusting data at the end of the Management. Pay attention that on Getrag transmissions the nut should be tightened in three stages. On ZF transmissions it is necessary to apply a compound for carvings on a carving. Establish a new lock plate and bend its ledges in the corresponding flutes.
- For the rest installation back to removal.

Switch shaft epiploon
|
|
- Perform the procedures of item 1-5 given above.
- On early models for a detachment from a shaft of the switch of a rod of the switch remove a lock ring of the plug, then a small punch beat out a pin.
- On late models for a detachment from a shaft of the switch of a rod of the switch establish the 3rd transfer, pull the spring plug back and beat out a pin.
- The tool for removal of epiploons or the small screw-driver pick up an epiploon (watch
the drawing). Make sure that at extraction of an epiploon, deepening under an epiploon will not be damaged.
- Apply lubricant on a fillet of a new epiploon, then put on an epiploon the end of a shaft of the switch. Hammer with a face head or a piece of a pipe of the suitable sizes an epiploon into place.
- Attach a switch rod to a switch shaft.
- Establish a flange (see above). For the rest installation back to removal.

Epiploon of an entrance shaft
|
|
- Remove transmission (look the Section Removal and installation of transmission).
- Remove the release bearing of coupling and the lever (watch the Head Stsepleniye).
- Remove bolts of the directing clutch coupling. On some models bolts not of the identical size therefore pay attention to an arrangement of bolts. Remove the coupling and all pro-rates under it.
|
|
Arrangement of bolts of the directing coupling (are shown by shooters). Getrag 265 transmission is shown. |
- The tool for removal of epiploons or the screw-driver take an old epiploon. Do not damage deepening under an epiploon.
- Apply lubricant on a fillet of a new epiploon and kill with a piece of a pipe of the suitable sizes him into place. If it is applied, replace a rubber ring of round section in a coupling flute.
- Clear fixing bolts and the condensed surfaces of the directing coupling, and also a carving under bolts in a case. On Getrag transmissions without ring of round section apply suitable sealant on the condensed surface of the directing coupling. Install the directing coupling and a pro-rate (pro-rates).
- Apply sealant on shoulders of bolts, establish bolts and tighten them.
- For the rest installation back to removal.

All epiploons
|
|
- Check the level of gearbox oil and, if necessary, add the recommended oil (watch Chapter Routine maintenance of the car).
- Lower the car, make control check and check existence of leaks.
