PERFORMANCE ORDER

1. Remove a head of cylinders. In engines in volume of 2,0 (DOHC), 2,5 and 3,0 liters remove camshafts and pushers.
	2. Compress in turn a spring of each of valves the special tool and remove konusny plugs. Remove plates of springs and a spring.
	3. By means of flat-nose pliers remove epiploons of rods of valves and remove saddles of springs.
	4. Remove valves. Combine valves and details corresponding to them in the separate numbered bags.

Carefully clean a head of cylinders and a detail of valves.

Cleaning

PERFORMANCE ORDER

1. Clean off the remains of old laying from a head surface.

2. Clean off a deposit from surfaces of chambers of combustion and wash out a head solvent. Clean valves.

3. Clean internal channels of a head.

Check

HEAD OF CYLINDERS

PERFORMANCE ORDER

1. Attentively examine a head on existence of cracks and other damages. At detection of cracks, it is necessary to replace a head.
	2. By means of a ruler and щупа check deformation of a surface of a head, if necessary a head it is necessary to process on the machine. For this purpose address to experts.
3. Examine saddles of valves in combustion chambers. If they cracked or scorched, it is necessary to replace them. For this purpose address to the expert. If saddles are only slightly scratched, they and a head of valves need to be processed abrasive structure.
4. If directing plugs of valves are worn-out, it is necessary to replace them. Measure diameters of rods of valves and internal diameters of directing plugs. Calculate a gap and compare the received size to technical requirements. If the gap exceeds admissible limits, replace plugs or valves. For this purpose address to the expert.

VALVES

PERFORMANCE ORDER

1. Examine heads and saddles of valves on existence of wear, scratches and cracks. Check, that the rod of the valve was not bent. At detection of strong wear it is necessary to replace valves.
	2. Measure diameters of rods of valves in several places if the received results strongly differ from each other, it means that the rod is worn-out and it is necessary to replace the valve.
	3. If heads and saddles slightly scorched, they can be ground special abrasive paste. To reach full tightness between the valve and its saddle, it is necessary to grind adjoining surfaces of the valve and a saddle. Put special abrasive paste on a valve head, insert it on a place and by means of the special tool turn in the parties.

DETAILS OF VALVES

1. Examine springs of valves on existence of damages and compare their length to length of new springs. If necessary replace springs.

2. Check, that springs were straight lines.

Assembly

PERFORMANCE ORDER

	1. Grease rods of valves and insert valves on places.
	2. Establish a spring saddle.
	3. Establish the protective plug of an epiploon.
	4. Establish an epiploon of a rod of the valve.
	5. Hammer an epiploon into place.
	6. Establish springs and plates of springs.
	7. Compress springs and establish konusny plugs.
8. Establish a head of cylinders.
