Folksvagen Sharan/Sharan repair>> Engine VR6>> Cranked shaft and radical bearings>> Epiploons of a cranked shaft
Forward and back 4 (fig. 85 see) epiploons of a cranked shaft should be changed after each removal of a cranked shaft or flanges of epiploons. Replacement of epiploons is spent, as a rule, with application of the special tool with observance of necessary safety measures. At detection of smudges of oil in the locations of epiploons their replacement is made. Replacement of epiploons can be spent on the established engine.
Removal of a forward epiploon of a cranked shaft is spent in a following order:
- Block a clamp a cranked shaft in a motionless condition and include transfer;
- Turn out a fastening bolt гасителя fluctuations which will tighten the moment 450 Н·м. On HUNDRED «Volkswagen» for this purpose usually use a clip;
- For removal of a forward epiploon:
- Turn out internal part A (fig. 86) a stripper 3203 approximately on three turns (about 4 mm) from an external part and fix a stripper in this position by adjusting screw B;
- Grease a carving head of the tool and put on it as it is possible further on an epiploon;
- ослабьте adjusting screw B also twist an internal part of the tool, with uniform pressure until the epiploon will not be squeezed out;
- Clamp a stripper in a vice and remove from it an epiploon nippers.
Removal of a back epiploon of a cranked shaft carry out in a following order:
- Remove a transmission, coupling and a flywheel;
- Establish the lever (fig. 87) a stripper 2086 on a flange of a cranked shaft and with its help remove a back epiploon;
- If the stripper 2086 is not present, the back epiploon can be removed by means of a screw-driver, thus it is necessary to watch, that the cover of an epiploon has not received damages;
- If the engine is removed, turn away a cover of a back epiploon and remove it together with an epiploon. Then from within beat out an epiploon from a cover.
Epiploon installation on the removed engine
At epiploon installation on the removed engine execute the following:
- Grease a working surface and an outer side of an epiploon with engine oil and it is cautious запрессуйте it in a cover so that the external surface of an epiploon has completely come inside. Working as a hammer, be cautious not to deform an epiploon;
- Cautiously spread a cover of an epiploon with the imposed lining on a cranked shaft and bolts fix it on the block of cylinders. Bolts tighten on a circle in regular intervals.
Epiploon installation on the engine
At installation of a forward epiploon on the engine execute the following:
- Put on directing plug 3266/1 (fig. 88) the special adaptation on a neck of a cranked shaft, grease the internal and external parties of an epiploon with engine oil and put on it directing plug;
- Put on directing plug 3266/1 other plug 3266 same tools (fig. 89) and tighten a bolt гасителя fluctuations of the cranked shaft, located on the centre until the epiploon will not sit down on the place;
- After installation of a forward epiploon remove all parts of the tool.
At installation of a back epiploon on the engine execute the following:
- By means of a hammer spread an epiploon on a cover. Be cautious and try not to damage a working edge of an epiploon;
- The adaptation 2003/1 (fig. 90) or metal circle with an aperture in the centre for edge of the cranked shaft, fixed by bolts in carving apertures of a press disk of coupling, in regular intervals tightening both bolts, запрессуйте an epiploon.
After installation of a forward or back epiploon on the engine all further works on assemblage are made in sequence, return dismantling, depending on what replacement of an epiploon has been made.
