Cam-shafts and regulators клапанного a backlash
|
|
- Do not turn cam-shafts or do not start the engine (i.e. valves should not work) about a half an hour after have repeatedly established hydraulic regulators клапанного a backlash and cam-shafts. As time is required that valves have risen on a place, start of the engine during a half an hour after repeated installation can lead to wrong gearing between valves or between valves and the piston.
- If air has got to a regulator клапанного a backlash, the valve can publish a tapping sound at inclusion of the engine after regulator installation клапанного a backlash. In that case start the engine on half an hour with a speed 2,000 – 3,000 turns in a minute and then air will be продут and knock will stop. If the sound постукивания not to stop, probably, a regulator клапанного a backlash the faulty. If it faulty, replace it. If a faulty regulator not probably to define on hearing among 16 regulators, spend the following check.
- About становите the engine also uncover cylinder heads.
-
Press a regulator a hand (having made effort less than 20 kg or 44 pounds), thus the cam crest should not be on a checked regulator, and check up, whether there is a backlash between a cam and a regulator. If is, the regulator is faulty and should be replaced.

Diagnostics of noise of a regulator клапанных backlashes
Regulator noise клапанных backlashes can be caused air which has got to regulators клапанных of backlashes, in following cases:
- The vehicle has staid about 24 hours and more.
- Have replaced engine oil.
- Have replaced or have repeatedly established a hydraulic regulator of a backlash.
- Engine major repairs.
If you suspect that noise goes from regulators клапанных backlashes, spend the following check.
|
|
- Check up engine oil.
- Oil level in маслосборнике
- If oil level low, add oil to a mark of full refuelling on oil щупе.
- If colour of oil has changed or quality of oil has worsened, replace it. Address to Section the Engine in the Head Maintenance service and greasing to receive recommendations about use of certain type of oil.
- If leak is found out, eliminate it.
- If pressure does not correspond to norm, lead to its norm.
- Include the engine on half an hour with a speed 2000 – 3000 turns in a minute, and then air will be blown, and the sound постукивания to stop.
- If постукивание has not stopped, probably, hydraulic regulator клапанного a backlash is faulty. If it is not serviceable, replace it. If a faulty regulator not probably to define on knock among 16 regulators, check up the following.
- Stop the engine and uncover cylinder heads.
- Press a regulator a hand (with effort less than 20 kg or 44 pounds), thus the cam crest should not be on a checked regulator, and check up, whether there is a backlash between a cam and a regulator. If is, the regulator is faulty and should be replaced.

Removal
|
|
- Disconnect a negative cable from the accumulator.
- Merge engine oil.
- Merge antifreeze.
- Remove маслосборник and a grid of the oil pump, having addressed to Razdelu Maslosbornik and a grid of the oil pump in this Chapter.

- Remove the gauge of position of a cam-shaft, having addressed to the Head System of ignition for engine J20.
|
|
- After will remove the second chain of synchronisation, establish a key on коленвале, having turned коленвал. It it is necessary to prevent gearing between valves and the piston.
|
|
|
- Untwist bolts картера a cam-shaft in that order as it is specified in drawing, and take out them.
|
- Remove картеры a cam-shaft.
- Remove cam-shafts.
- Remove regulators клапанного a backlash (2).
|
|
-
Never assort a hydraulic regulator клапанного a backlash.
- Do not press on the regulator case, the oil which is in the chamber under a high pressure, will follow.
- Lower the taken out regulator in pure engine oil (1) and store it there until will establish it repeatedly to prevent oil leak. If you leave it on air, put it in it ковшеобразном the case a face sheet downwards. Do not put it sideways or in ковшеобразном the case a face sheet upwards.

|
With the help a micromeasure measure cam height. If the measured height below norm, replace a cam-shaft. |

|
Deterioration of a cam-shaft
|
|
Put a cam-shaft between two V-shaped blocks, and measure its deterioration with the help циферблатного the indicator. If the measured deterioration exceeds specified below norm, replace a cam-shaft. Deterioration of a cam-shaft: a limit: 0.10 mm (0.0039 inches). |
Deterioration of necks of a cam-shaft
|
|
|
|
- Check up necks of a cam-shaft and картеры a cam-shaft on a subject изъязвления, scratches, deterioration or damage. If any malfunctions are found, replace a cam-shaft or a head of the cylinder with картером. Never replace a head of the cylinder without replacement картеров.
|
- Check up a backlash by means of a plaster solution. It becomes as follows.
- Clean картеры and cam-shaft necks.
- Be convinced of that all regulators клапанного a backlash are removed and establish a cam-shaft on a cylinder head.
- Put a part of a plaster solution for full width of a neck of a cam-shaft (in parallel a cam-shaft).
- Establish картер a cam-shaft.
|
|
- Twirl bolts картера a cam-shaft in the small portions while they will not be fastened with the specified rotating moment. The rotating moment of an inhaling: the Bolt картера a cam-shaft () — 11 Н•м (1.1 kg th, 8.0 pound on foot).
|
|
|
Do not rotate a cam-shaft with a plaster solution inside. |
|
|
- Remove картер and by means of a ruler (2) on a surface of a plaster solution (1) measure width of a plaster solution in the widest place.
- Backlash of a neck of a cam-shaft:
- Norm: 0.045 – 0.099 mm (0.0018 – 0.0038 inches)
- Limit: 0.12 mm (0.0047 inches)
|
|
|
- If the measured backlash of a neck of a cam-shaft falls outside the limits norm, measure internal diameter of a neck and external diameter of a neck of a cam-shaft. Replace a cam-shaft or knot of a head of the cylinder, depending on where the deviation from technical characteristics is more.
|
- Internal diameter of a neck of a cam-shaft (on an admission and on release)
- Norm: 26.000 – 26.033 (1.0237 – 1.0249 inches)
- External diameter of a neck of a cam-shaft (on an admission and on release)
- Norm: 25.934 – 25.955 (1.0211 – 1.0218 inches)

|
Deterioration of a hydraulic regulator клапанного a backlash
|
|
|
|
- Check up a regulator on presence изъязвлений, scratches or damage. If any defect is found out, replace it.
|
|
|
- Measure internal diameter of a head of the cylinder and external diameter of a regulator to define a backlash between a head of the cylinder and a regulator. If the backlash exceeds norm limits, replace a regulator or a cylinder head.
|
|
|
