Oil change caps replacement

Replacement of oil-removal caps VAZ is carried out in a certain order. First of all, the wire from the negative battery terminal is disconnected . Then remove the toothed pulley from the camshaft. Then the head cover of the unit is removed.

After that, unscrew the fixing nuts of the "ground" wires and remove the tips from the studs. After that, it is necessary to unscrew the nuts and the bolt in the fastening of the back cover on the head of the unit. Pay attention to the O-ring installed under the head of the bolt. Further, it is necessary to unscrew the nuts at the front and rear bearing housings and the camshaft evenly. After that, both cases are removed. If the key is located in the groove of the camshaft loosely, then it should be removed (not to lose).

The following actions will be the following: removal of the camshaft from the head of the block and the stuffing box from the camshaft.

Then the crankshaft must be turned to place the piston, which corresponds to the oil-removable caps of the VAZ, is located at the dead point (top). After the candle is turned out, it is recommended to insert a tin rod through the hole between the valve and the piston. So the valve does not fall down.

Using a special device, you should compress the valve springs, then use the tweezers to remove the biscuits. Then remove the upper spring plate, the outer and inner valve springs.

The replacement of the oil removable caps starts with the pressing of the valve plug guide. To do this, install the collet of the special tool. After installing it on the cap, you should hit the hub sharply on the hub, and then on the handle of the handle of the device used. If there is no device, you can use the pliers. It should be said that in this case, replacing oil-removable caps will become a relatively time-consuming task. When the work is done with pliers, the applied force must be applied exclusively upwards. The main task is to prevent cranking, so as not to damage the guide bushings.

The oil-removal caps are replaced after removing the spring from them. So you can avoid damage while passing through the grooves on the valves under the crackers.

Replacement of oil-removal caps is carried out with the use of engine oil. Before installation, the elements are recommended to be dipped into it. Then it should be installed in the mandrel.

After installation, you should carefully press the cap into the bottom plate until it stops. After that, it is necessary to install the spring (if it was removed).

All actions should be repeated for each cap.

In the reverse order of removal, it is necessary to install a valve plate and springs. Using a special device, you need to put biscuits. They should take place in the grooves of the stem valve. In order to compact the biscuits (that they sit in their place), you should gently hammer the ends of the valves through the metal rod.

The cams and camshaft necks must be lubricated with oil (motor). The support surfaces intended for the camshaft neck in the cylinder head and bearing housings should also be treated.

Installation of a camshaft in supports of a head of the block carry out so that the cams in the first cylinder had a direction aside from valve pushers.

The sealant should be applied to the head of the unit. Sealed should be the area of the extreme camshaft supports.

Then it is necessary to install the camshaft and bearing housings, to put the washers on the studs, to wrap the nuts. Tighten fastening is necessary in two stages. It is necessary to first tighten the nuts before touching the bearing housings to the surface of the head. In this case, it is necessary to ensure that the guide bushings enter completely into the holes of the bearing housings. After this, the nuts are tightened permanently. Then all the details are set in the reverse order of removal.
