Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Transmission>> Automatic transmission>> Transmission maintenance
To units on which reliability and durability of transmission first of all depend, belong a cooler of transmission liquid with the filter and the liquid receiver with the mesh filter of the rough cleaning, located in the pallet from the bottom party of a case. If necessary liquid plum from a transmission case, and also for access to the receiver of liquid and other details of the block of valves the pallet can be removed.
At big run of the car tightness of epiploons of flanges of differential owing to what fall of level of oil in the main transfer is possible can be broken. If necessary it is possible to replace epiploons, without removing a transmission.
The cooler represents the two-chamber heat exchanger located in the top part of a case of transmission. On one chamber of a cooler cooling liquid from the engine, and on another — transmission liquid that promotes maintenance of thermal balance circulates. If the temperature of transmission liquid exceeds temperature of cooling liquid, heat is transferred to the last and the temperature of transmission liquid decreases. The cooler does not demand periodic service. Exceptions are leakage of cooling liquid or cooler damage.
In need of cooler replacement (fig. 8.73) surely replace sealing ring laying.
The filter of transmission liquid was established on cars 1990 and the beginnings of 1991 of release, but in February, 1991 release of these details stopped. Replacement of elements can be carried out in the specialized centers "Volkswagens" to the period before the next maintenance.
At removal of the filter wrap up rags its basis not to spill liquid on a case. To turn on the filter of transmission liquid follows for a fringing in the top part of the case, or a tape stripper for an otvorachivaniye of the oil filter of the engine. Remove the filter, previously having waited while liquid will not flow down from the filter back in a cooler. Wipe a place of a prileganiye of the filter a pure fabric and wrap a bolt with new ring laying.
Block of valves and liquid receiver
The pallet, the receiver of liquid and the block of valves are placed in the lower part of a case of transmission (fig. 8.74) . Before installation of the receiver of liquid previously establish laying in a seat.
At installation of the pallet track correctness of laying of consolidation on a contour round the pallet. Before a tightening of bolts be convinced available remote plugs on all four angular openings.
Epiploon of a flange of a semi-axis
It is possible to replace epiploons of flanges of a semi-axis, without removing transmission. Removal of a flange needs a VW 39 type stripper, приворачивающийся by bolts to a flange and a removing flange at the expense of ongoing effort.
Replacement of an epiploon of a semi-axis carry out in the following order:
turn out a six-sided key bolts of fastening and disconnect the internal hinge from a flange;
take a dustproof cover and remove the spring lock ring holding a flange on a shaft. By means of a stripper press a flange from a shaft;
take an epiploon from a flute by means of a stripper of VW 681 or having accurately hooked it a screw-driver. Try not to scratch thus a flute surface under an epiploon or an adjacent surface;
fill a cavity of a new epiploon with universal greasing then press an epiploon into place before complete landing (see fig. 8.75 );
check wear existence on the surface of a flange interfaced to an epiploon. At too big development replace a flange;
establish a flange into place by means of the adaptation with a bolt which is rolling in a leading shaft (fig. 8.76) ;
put on a flange shaft a new lock ring from an end face. Without making big effort, establish a ring before dense landing in a shaft flute;
attach the hinge to a semi-axis flange.
