2.1.10. Replacement of forward epiploons
|
|
All epiploons are established by sponges inside (to the engine). |
Engines M10 and М30 (with a distributive chain)
Forward epiploon of a cam-shaft (only for M30 engines)
|
|
- Remove only the top cover of a distributive chain (see. Section Removal and installation of covers of a distributive chain).
- Prop up a cover two wooden whetstones and beat out an epiploon from the back party by means of a hammer and a screw-driver. Be careful, trying not to damage in the course of work an opening for an epiploon.
- Cover external diameter and sponges of a new epiploon with universal greasing and establish an epiploon in a cover by means of a hammer and a replaceable head with a diameter, slightly smaller, than external diameter of an epiploon.
- The rest of installation make as it should be, the return to removal.
|
|
Forward epiploon of the crankshaft (engines M10 and М30)
|
|
- Remove a pulley of the crankshaft and a damper of krutilny fluctuations (see. Section Removal and installation of covers of a distributive chain).
- Carefully take an old epiploon from a cover by means of a big screw-driver. Be extremely careful not to damage a screw-driver an opening for an epiploon or the crankshaft. Wrap up a screw-driver sting an insulating tape to prevent possible damages.
- Clear an opening for an epiploon in a cover, cover external edge of a new epiploon with engine oil or universal greasing. Also grease epiploon sponges with universal greasing. Using a replaceable head with a diameter, a little smaller, than external diameter of an epiploon, carefully establish a new epiploon into place by means of a hammer.
|
|
- If available there is no suitable replaceable head, the short piece of a pipe of big diameter will approach.
|
- Check an epiploon after installation to make sure that the spring round inside of sponges of an epiploon did not jump out.
- The rest of installation make as it should be, the return to removal.

|
Engines M20 and М40 (with a distributive belt)
Forward epiploon of a cam-shaft (engines M20 and М40)
|
|
- Remove a distributive belt and a cam-shaft asterisk (see. Section Removal, survey and installation of a distributive belt and asterisks of its natyazhitel).
- Only on the M20 engine give two screws and remove a casing of an epiploon of a cam-shaft from a head of cylinders, pulling together and at the same time turning it forward and back.
- Only on M20 engines prop up a casing two wooden whetstones and with the help hammers and screw-drivers take from it an epiploon. Be very careful not to damage an epiploon casing.
- On M40 engines take an epiploon from a head of cylinders by means of a screw-driver, trying not to damage a surface of a cam-shaft or an opening for an epiploon.
- Cover sponges and external diameter of a new epiploon with universal greasing.
- On M40 engines wrap up a sticky tape the cam-shaft end to protect a new epiploon from damage by an adjusting flute during its installation.
|
|
- Accurately put a new epiploon on a place and at first press it a hand that it entered into an opening. Establish an epiploon in a casing or a head of cylinders (that is provided) by means of a hammer and a replaceable head with a diameter, a little smaller, than external diameter of an epiploon. On M40 engines remove a sticky tape from the cam-shaft end.
|
- On M20 engines replace a sealing ring of round diameter in a back part of a casing of an epiploon and pull epiploon sponges for the cam-shaft end. Establish screws and tighten them with demanded effort.
- The rest of installation make as it should be, the return to removal.
|
|
Forward epiploons of cranked and intermediate shaft (M20 engines)
|
|
- Remove a distributive belt and pulleys of cranked and intermediate shaft if are provided (see. Section Removal, survey and installation of a distributive belt and asterisks of its natyazhitel).
|
|
We recommend to replace a distributive belt each time at its removal. |
- Give bolts and nuts of fastening of a forward cover to the block of cylinders. Do not forget to give three bolts from below, holding a forward part of the pallet of a case on the lower part of a forward cover.
- Carry out a thin sharp knife between laying of the pallet of a case and a forward cover, separating thus laying from a cover. Be very careful not to damage and to soil laying that you could use it again then.
- Destroy laying hermetic between a forward cover and the block of cylinders, обстучав a cover a hammer with rubber brisk or a usual hammer, having put wooden whetstone. Do not push anything between a cover and the block not to damage a laying surface.
- Using a scraper, remove all traces of a material of old laying from interfaced surfaces of covers and the block of cylinders.
|
|
Be extremely careful not to damage and to scratch soft aluminum surfaces. Besides, try not to damage and not to soil laying of the pallet of a case. On sale are available, and there can be useful, special solvents for removal of laying. After complete removal of a material of laying of a surface of laying it is possible to degrease, having wiped them a rag moistened in suitable solvent. |
- Prop up a cover two wooden whetstones and beat out an epiploon from the back party by means of a hammer and a screw-driver. Be careful, trying not to damage in the course of work an opening for an epiploon.
- Cover external diameter and sponges of a new epiploon with universal greasing and establish an epiploon in a cover by means of a hammer and a replaceable head with a diameter, slightly smaller, than external diameter of an epiploon.
- Apply a thin film RTV type hermetic on a surface of laying of the pallet of the case, interfaced to a forward cover. Put more hermetic on regions where laying adjoins to the block of cylinders.
|
|
If laying of the pallet of a case is damaged, instead of complete replacement of laying you can try to cut off its forward part where it adjoins to the block of cylinders, then to cut off a forward part of new laying that it was just the same size. Cover an internal surface of the pallet a piece of rags, then clean off all traces of a material of old laying from interfaced surfaces. Attach a piece of new laying to the pallet by means of special gluing substance, then put RTV hermetic as it is described at the beginning of this paragraph. |
- Grease both parties of new laying with RTV hermetic, attach a forward cover to a forward part of the engine, carefully getting epiploons on cranked and intermediate shaft. Get bolts and tighten them with demanded effort. Tighten bolts one by one according to the crosswise scheme to make it evenly.
|
|
At first tighten bolts of fastening of a forward cover to the block of cylinders, then bolts of fastening of the pallet of a case to a cover. If laying acts over connection of a cover with the block or forms folds in connection of a cover with the pallet, cut it that it stood correctly. |
|
|
After RTV hermetic drawing assembly should be finished within 10 minutes to be in time before hermetic hardening. |
- The rest of installation make as it should be, the return to removal.

|
Forward epiploon of a cranked shaft (M40 engines)
|
|
- Remove a distributive belt and a crankshaft asterisk (see. Section Removal, survey and installation of a distributive belt and asterisks of its natyazhitel).
- Take a segment shponka from a flute on the crankshaft end.
- Notice the provision of an epiploon, then take it from a forward cover by means of a screw-driver, but try not to damage an opening for an epiploon or a crankshaft surface. If the epiploon became attached, drill two small openings in a metal part of an epiploon and by means of two саморезов take an epiploon. Do not forget to remove all metal shavings.
- Cover external diameter and sponges of a new epiploon with universal greasing and establish an epiploon in a cover by means of a hammer and a replaceable head with a diameter, slightly smaller, than external diameter of an epiploon. Make sure that the epiploon rose into place exactly.
- The rest of installation make as it should be, the return to removal. Do not forget that it is recommended to replace a distributive belt - see. Section Removal, survey and installation of a distributive belt and asterisks of its natyazhitel.
