The prevention

Special tools and details which at you can and not to be are necessary for carrying out of a partition and check of a head of cylinders. Therefore if you the fan will buy much more economically a new head than to waste time on a partition and repair of the old.


1. Remove a head of cylinders, camshafts and pushers of valves.
2. Before to remove valves prepare the separate numbered bags to combine in them valves and details corresponding to them.
3. Compress a spring of the first valve and remove clamps by means of a magnet. Remove a spring plate, a spring and a spring saddle.
4. Get the valve from a head. If the valve does not pass through directing plug, smooth out edges of the end of a rod of the valve an emery paper. Take an epiploon of a rod of the valve from the directing plug.
5. Do similar procedures with other valves.
6. After you have disassembled a head, it is necessary for cleaning and checking up.


1. Clean off all traces of old linings from surfaces of a head and wipe its solvent.
2. Clean the adjournment formed in internal channels and apertures of a head. If rust adjournment have blocked water channels of a head, address to the expert.
3. By means of a suitable tap and compressed air clean carvings in apertures of bolts of a head.
4. Will brush carvings of adjusting pins of inlet and final collectors.
5. Wash out a head in solvent and dry up it.
6. Wash out in solvent valves and their elements. Dry up all details.



1. Examine a head on presence of cracks, traces of leak of a cooling liquid and other damages. At detection of cracks, the head is necessary for processing on the machine tool if too strong, a head it is necessary to replace damages.

2. By means of a ruler and measuring probeа check up deformation of joined surfaces of a head. If deformation exceeds admissible limits a head it is necessary to process in a specialised workshop.
3. Examine saddles of valves if they are damaged, address to the expert.

4. Measure a backlash between a rod of the valve and the directing plug by means of the measuring device. Instrument readings are necessary for dividing into two and you receive backlash size. If the backlash exceeds the admissible limits, it is necessary to replace directing plug of the valve.


The prevention

All works connected with maintenance service of valves demand special knowledge and the special equipment and consequently should be given the expert.

Check of deterioration of valves

1. A valve emphasis

2. Flutes of clamps of a spring

3. A valve rod

4. A valve facet

5. A valve edge

6. The final valve

7. The inlet valve

1. Examine facets of valves on presence of deterioration, deformation, the cracks, the burnt sites and other damages. Check up rods of valves on presence of the wiped sites and cracks. Check up, whether rods are bent. At detection of any damages valves are necessary for processing in a specialised workshop.
2. Measure width of an edge of the valve. If the received size less than admissible limits, it is necessary to replace the valve.


1. Examine springs of valves on presence of deterioration and damages. Measure length of springs. If length of any spring less than the limit specified in technical characteristics, replace it.
2. Check up, that springs were straight lines. If necessary replace the deformed springs.


1. Grease directing plugs and rods of valves with engine oil and insert valves into a head of cylinders.

2. Oil epiploons of rods and establish on the places. Epiploons of rods of inlet and final valves differ from each other. Epiploons of final valves have ledges in the top part.
3. Establish saddles of springs, springs and plates of springs.

4. Compress springs and establish clamps, if necessary put on clamps hermetic.
