Replacement of a forward epiploon of a bent shaft


1. Remove a pulley of a bent shaft (see the Section Removal and installation of a pulley of a bent shaft), forward covers and a belt of the GRM drive (see the Section Removal and installation of a gas-distributing belt and cogwheels of the GRM drive).
2. Having accurately hooked two screw-drivers or big mount, remove a cogwheel from a shaft pin, - try not to damage the case of the oil pump.
3. If it is not possible to remove a wheel by a poddevaniye, it is necessary to drill couple of openings in its face surface, to cut in them a carving, and then to use a stripper of bolted type.

The drilled cogwheel is subject to replacement!

4. Remove an internal guide of a belt, - try to remember by what party outside it was established on a shaft pin, in case of need put the corresponding marking.

5. Having accurately hooked the small screw-driver, take an old epiploon from the landing nest, - try not to damage a shaft pin.

7. Manufacture adaptation for press fittings of a new epiploon of a piece of a pipe, a big flat washer and a long bolt in landing a nest. Outer diameter of a pipe has to be equal, or it is slightly less than outer diameter of an epiploon, it is necessary to chamfer keen edges. The carving of a bolt has to have the same size, as a bolt of fastening of a pulley of a bent shaft. The washer has to rest with guarantee against a face surface of a mandrel and provide a reliable support for a bolt head. Fill an epiploon in a landing nest, then install adaptation, screw a bolt in a shaft pin end face, and, tightening it a key, press an epiploon. As soon as the epiploon rests against a nest bottom, tightening of a bolt should be stopped.

8. Put on a shaft pin an internal guide of a gas-distributing belt (the concave party outside).
9. Make sure that the spline did not drop out of the groove in a pin.
10. Slightly grease with universal lubricant an internal surface of a cogwheel and put it on a shaft pin.
11. Installation of the remained components is made as it should be the return to an order of their dismantle. The description of the procedure of adjustment of effort of a tension of a gas-distributing belt is provided in Section 7. track that all fixture was tightened with the required effort.
