Cam-shafts and regulators of a klapanny gap
|
|
- Do not turn cam-shafts or do not start the engine (i.e. valves should not work) about half an hour after repeatedly established hydraulic regulators of a klapanny gap and cam-shafts. As time is required in order that valves rose into place, engine start within half an hour after repeated installation can lead to the wrong gearing between valves or between valves and the piston.
- If air got to a regulator of a klapanny gap, the valve can publish a tapping sound at turning on of the engine after installation of a regulator of a klapanny gap. In that case start the engine on half an hour with a speed 2,000 – 3,000 revolutions per minute, and then air will be blown and knock will stop. If the sound of a postukivaniye not to stop, probably, a regulator of a klapanny gap the faulty. If it faulty, replace it. If it is not possible to define a faulty regulator aurally among 16 regulators, carry out 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 crest of a cam should not be on a checked regulator, and check, whether there is a gap between a cam and a regulator. If is, the regulator is faulty and should be replaced.

Diagnostics of noise of a regulator of klapanny gaps
Noise of a regulator of klapanny gaps can be caused by the air which has got to regulators of klapanny gaps, in the following cases:
- The vehicle staid about 24 hours and more.
- Replaced engine oil.
- Replaced or repeatedly established a hydraulic regulator of a gap.
- Major maintenance of the engine.
If you suspect that noise goes from regulators of klapanny gaps, carry out the following check.
|
|
- Check engine oil.
- If oil level low, add oil to a mark of complete filling on oil щупе.
- If color of oil changed or quality of oil worsened, replace it. Address to the Section Engine in Head Maintenance and greasing to receive recommendations about use of a certain type of oil.
- If leak is found, eliminate it.
- If pressure does not correspond to norm, lead it to norm.
- Turn on the engine on half an hour with speed of 2000-3000 revolutions per minute, and then air will be blown, and the sound of a postukivaniye to stop.
- If the postukivaniye did not stop, probably, the hydraulic regulator of a klapanny gap is faulty. If it is not serviceable, replace it. If it is not possible to determine a faulty regulator by knock among 16 regulators, check 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 crest of a cam should not be on a checked regulator, and check, whether there is a gap between a cam and a regulator. If is, the regulator is faulty and should be replaced.

- Remove the second chain of synchronization, having addressed to the Section the Second chain of synchronization and a natyazhitel of a chain in this Chapter.
- Remove the sensor of provision of a cam-shaft, having addressed to Head ignition System for the J20 engine.
|
|
- After will remove the second chain of synchronization, establish a key on the crankshaft, having turned the crankshaft. It it is necessary to prevent gearing between valves and the piston.
|
|
|
- Untwist bolts of a case of a cam-shaft in that order as it is specified in drawing, and take out them.
|
- Remove cam-shaft cases.

- Remove regulators of a klapanny gap (2).
|
|
-
Never assort a hydraulic regulator of a klapanny gap.
- Do not press on the regulator case, the oil being 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 leakage of oil. If you leave it on air, put it in its kovsheobrazny case the face down. Do not put it sideways or in the kovsheobrazny case the face up.

Wear of a cam-shaft
|
|
Put a cam-shaft between two V-shaped blocks, and measure its wear by means of the tsiferblatny indicator. If the measured wear exceeds specified below norm, replace a cam-shaft. Wear of a cam-shaft: limit: 0.10 mm (0.0039 inches). |
Wear of necks of a cam-shaft
|
|
|
|
- Check necks of a cam-shaft and cam-shaft cases about an ulceration, scratches, wear or damage. If any malfunctions are found, replace a cam-shaft or a cylinder head with a case. Never replace a cylinder head without replacement of cases.
|
- Check a gap by means of plaster solution. It becomes as follows.
- Clean cases and cam-shaft necks.
- Be convinced of that all regulators of a klapanny gap are removed and establish a cam-shaft on a cylinder head.
- Put a part of plaster solution for full width of a neck of a cam-shaft (parallel to a cam-shaft).
- Establish a cam-shaft case.

|
|
|
Do not rotate a cam-shaft with plaster solution inside. |
|
|
- Remove a case and by means of a ruler (2) on a surface of plaster solution (1) measure width of plaster solution in the widest place.
- Gap of a neck of a cam-shaft:
- norm: 0.045-0.099 mm (0.0018 – 0.0038 inches)

|
|
|
- If the measured gap 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.
|

|
|
|
- Check a regulator on existence of ulcerations, scratches or damage. If any defect is found, replace it.
|
|
|
- Measure internal diameter of a head of the cylinder and external diameter of a regulator to define a gap between a head of the cylinder and a regulator. If the gap exceeds norm limits, replace a regulator or a cylinder head.
