Dismantling
Removal of hydraulic pushers of valves
|
And – a flute arrangement for supply of oil in a hydraulic pusher. |
PERFORMANCE ORDER |
1. Remove a head of the block of cylinders from the engine and clear its external surface of dirt. |
2. Remove a casing of the thermostat and the thermostat. |
3. Remove collectors from a head of the block of cylinders. |
4. Unscrew spark plugs and remove the ignition distributor. |
5. Remove camshafts. |
6. Using a rubber sucker, remove hydraulic pushers of valves. Do not overturn a head of the block of cylinders for extraction of hydraulic pushers at all. You store gidravl chesky pushers in a container with engine oil in vertical position. At the same time the flute for supply of oil in a hydraulic pusher has to be located from below (see the drawing). |
7. Remove yokes, blocks of axial pressure and hydraulic pushers from a head of the block of cylinders. Using the device for compression of a spring of the valve, squeeze each spring and remove crackers from a valve end face. Remove the device for compression of a spring and take a plate and a spring. Flat-nose pliers, being careful, take a maslootrazhatelny cap from a valve rod. Take the lower plate of a spring. |
8. When the spring of the valve is compressed and the cup of a spring is not removed from crackers, it is necessary to strike with the hammer through wooden whetstone a spring cup that will lead to release of crackers. |
9. Take the valve via the combustion chamber. Each valve you store in a separate plastic bag together with a plate springs, a spring, a nest of a spring and crackers for their further installation on the places. |

Check
PERFORMANCE ORDER |
1. Remove the remains of old laying from a head of the block of cylinders. |
2. Clear a deposit from combustion chambers, then wash up a head in the corresponding solvent. |
3. Clear of carbonaceous deposits of the valve, it is possible even with application of a wire brush. |
4. Carefully examine a head of the block of cylinders on existence of cracks and other damages. In the presence of cracks the head is subject to replacement. |
5. Using a metal ruler and the probe, check planeness of the interfaced surface of a head of the block of cylinders. At not planeness of more than 0,1 mm it is necessary to pereshlifovat a head, at the same time its height has to conform to requirements. |
|
|
6. Check a condition of saddles of valves. If they are burned, worn-out or have defects, they need to be replaced. If wear of a saddle of the valve is insignificant, they need to be ground in. Check the directing plugs of valves for wear, inserting into them a core of the valve and moving it aside. Movement has to be insignificant. If movement is excessive, take the valve and measure diameter of a core of the valve. If necessary replace the valve. If the core of the valve is not worn-out, so the directing plug which needs to be replaced is worn-out. Replacement of the directing plugs of valves should be made at service station. |
7. If saddles of valves have to be pereshlifovana, this operation needs to be executed after installation of new guides of valves. |
|
Assembly
PERFORMANCE ORDER |
1. Oil cores of valves engine and insert them on the places. Install the valve on those places where they were ground in. |
2. Install the lower cup of a spring. |
3. In a set of new maslootrazhatelny caps there is an adjusting plug which is installed on a core of the valve and protects working edges of maslootrazhatelny caps at their ustan ке. Install the adjusting plug on a valve core, lower a maslootrazh a telny cap in fresh engine oil and establish it on a valve core into place, being careful not to damage its working edges. For installation of maslootrazhatelny caps use a special metal mandrel. |
4. Establish a valvate spring and the top cup of a spring. |
5. Special adaptation squeeze a valvate spring and establish crackers in dredging of a core of the valve and grease them. Remove the device for compression of a spring. Repeat this operation on other valves. |
6. Knock with a hammer through wooden whetstone on a valve core end face in order that all elements of the valve accurately were established on the places. |
7. Establish hydraulic pushers of valves in a head of the block of cylinders on the same places where they faced removal. Before installation of pushers grease nests in a head of the block of cylinders with pure engine oil. At installation new hydraulic to a tolkata leu lower them in a container with pure engine oil and several times manually squeeze them to fill them with oil. |
8. Install camshafts. |
9. Screw in spark plugs and install the ignition distributor. |
10. Establish collectors, the thermostat and a casing of the thermostat. |
11. Establish a head of the block of cylinders. |
