Replacement of epiploons

Right epiploon of a bent shaft

 PERFORMANCE ORDER

1. Remove a cogwheel of a bent shaft (see Removal and installation of cogwheels of a belt of the GRM drive).
2. Measure and write down the landing depth of an epiploon.

3. By means of a suitable hook take an epiploon from the casing. Alternatively, drill or puncture couple of openings in a face surface of an epiploon, screw in them self-tapping screws and take an epiploon, having grasped with nippers heads of screws.

4. Clear a casing of an epiploon and carefully remove from walls of a nest and a pin of a shaft all roughnesses and teases capable to lead to failure of a new epiploon.
5. Oil sponges of a new epiploon pure motive, then accurately put it on former depth in a nest in a casing (the opened end inside). As a mandrel use a replaceable head of the corresponding size or a piece of a pipe of suitable diameter (the mandrel has to rest only against the firm outer edge of a face surface of an epiploon). For protection of an epiploon wind a pin of a bent shaft with a thin adhesive tape and put on it assembly of a casing with an epiploon.
6. Remove an adhesive tape.
7. Establish into place a cogwheel of a bent shaft (see Removal and installation of cogwheels of a belt of the GRM drive).

Left epiploon of a bent shaft

 PERFORMANCE ORDER

1. Remove a flywheel / a driving disk (see Removal, check of a state and installation of a flywheel / a driving disk).
2. Perform the procedures described in subsection the Right epiploon of a bent shaft, subitem 2 — 6 with that difference that this time the epiploon is put by external sponges outside. If sponges at installation of an epiploon are turned out, straighten them by means of a suitable hook. Try not to damage an epiploon.
3. Establish into place a flywheel / a driving disk (see Sensors of level, pressure and temperature of motive oil - the general information).

Right epiploon of the camshaft

 PERFORMANCE ORDER

1. Remove a camshaft cogwheel (see Removal and installation of cogwheels of a belt of the GRM drive). In effect, there is no need of full removal of a gas-distributing belt, however it is worth to remember about high probability of pollution it oil.

2. Having hooked a suitable hook, take an epiploon from the casing. Alternatively, the epiploon can be taken by means of self-tapping screws (see subsection the Right epiploon of a bent shaft, item 3).

3. Carefully clear a casing of an epiploon and a surface of a pin of the camshaft.
4. Oil sponges of a new epiploon pure motive and put him on a shaft pin (the opened end forward). For protection of sponges the pin should be wound with an adhesive tape previously.
5. By means of a suitable mandrel press an epiploon in the casing aflush with a face surface of a head of cylinders. Use a bolt of M10 which should be screwed in a carving opening in a shaft end face, washers and a piece of the pipe suitable on diameter.
6. Establish into place a camshaft cogwheel (see Removal and installation of cogwheels of a belt of the GRM drive).
7. If removed, establish a gas-distributing belt (see a GRM drive Belt - the general information, removal, check of a state and installation).

 

Left epiploon of the camshaft

Consolidation of the left pin of the camshaft is made means of the sealing ring put in a flange of a face plate. The epiploon is not provided. Replacement of a sealing ring is made by a plate otbolchivaniye from a head of cylinders.
