Check

HEAD OF CYLINDERS

PERFORMANCE ORDER
1. Carefully examine head surfaces on existence of cracks and damages. At detection of any damages address to experts.
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.

CAMSHAFT

PERFORMANCE ORDER
1. Examine cams and necks of bearings of a camshaft on existence of wear and damages. If necessary it is necessary to make replacement of a camshaft, a head and covers of bearings.

2. Measure a free wheeling of a camshaft by means of the special measuring device.
3. Check a lubricant gap of each bearing of a camshaft.
4. Clean solvent bearings and covers of bearings. Establish shaft on places. Put on each bearing a strip of measuring plastic. Establish covers of bearings and tighten bolts of covers.
5. Unscrew bolts and remove covers. Compare width of the compressed strip to the measuring table. If necessary replace a camshaft or a head of cylinders.
6. Clean off the plastic remains.

VALVES

PERFORMANCE ORDER
1. Examine heads and saddles of valves. If heads and saddles slightly scorched, they can be ground the most special abrasive paste, but it is better, if you address to experts.
2. Measure diameters of rods of valves.
3. Check a gap between a rod of the valve and the directing plug if it exceeds admissible norms, address to experts.
4. Examine springs of valves on existence of damages and compare their length to length of new springs. If necessary replace springs.
5. Check, that springs were straight lines.

Assembly

PERFORMANCE ORDER
1. To reach full tightness between the valve and its saddle, it is necessary to grind adjoining surfaces of the valve and a saddle.
2. Put special abrasive paste on a valve head, insert it on a place and by means of the special tool turn in the parties.

3. Establish saddles of springs.
4. Oil rods of valves and insert them on places.
5. Put on rods plastic caps.
6. Establish epiploons of rods and remove protective caps.
