Removal, check of a state and installation of camshafts

REMOVAL

 PERFORMANCE ORDER

1. Uncover heads of cylinders (see the Section Removal and installation of covers of heads of cylinders), a gas-distributing belt and cogwheels (see the Section Removal, check of a state and installation of a gas-distributing belt and cogwheels of the GRM drive).
2. Remove the ignition distributor (see the Head Elektrooborudovaniye of the engine).
3. Remove assemblies of yokes (see the Section Removal, check of a state and installation of assembly of yokes).

4. Remove the EGR valve (see the Head Engine management) for the purpose of ensuring access to a back plate of fastening of a camshaft.

Before taking camshafts, measure their axial side play.

5. Remove a plate of the holder of a back camshaft.

6. Accurately take a camshaft from a head of cylinders, trying not to damage its cams and necks.

CHECK

 PERFORMANCE ORDER

1. Remembering an order of ustanovkiotdelny details, make dismantle of assembly of yokes, then priboltit the axes exempted from components on the regular places in a head of cylinders. Tighten fixture with the demanded effort.

2. Fix the dial measuring instrument so that its plunger rested against a camshaft end face. Take away a shaft back against the stop (the end of the lever wind with an adhesive tape in order to avoid damage of working surfaces of a shaft), nullify the measuring instrument, then shift a shaft against the stop to the opposite side. Consider indications of the measuring instrument, write down result and compare it to standard requirements to an axial side play of camshafts (see Specifications). If the read instrument exceeds the limit of admissible range, the shaft is subject to replacement.

3. Having checked an axial side play, remove axes of yokes, then take a shaft from a head of cylinders. Measure diameters of necks and height of cams. Verify results of measurements with requirements of the Specification (for V6 engines). Visually estimate degree of wear of shaft, - pay attention to such things, as scratches, teases, cavities and signs of an overheat.

Pay attention to difference in an arrangement of cams on forward and back camshafts.

INSTALLATION

 PERFORMANCE ORDER

1. Remove back covers of a gas-distributing belt from both heads of cylinders for the purpose of ensuring access to epiploons of camshafts.

2. Replacement of epiploons has to be made every time when dismantling head/dismantle of shaft. Extraction of old epiploons is made by a poddevaniye by their special tool, or a screw-driver with a flat sting.

3. Oil sponges of a new epiploon pure motive, then put it perpendicularly in the nest on the same depth on what the old epiploon was put. As a mandrel for landing of an epiploon it is possible to use a face head of the corresponding size, or a piece of a pipe of suitable diameter.

4. Carefully wipe the rags moistened in acetone a camshaft, beds of its bearings in a head of cylinders and covers, and also yokes of the drive of valves. Try to remove completely the slightest traces of slime and dirt. For rubbing of components use only pure nevorsyashchuyusya rags. Grease necks and cams of a shaft with special assembly greasing and accurately establish a shaft on regular places in the head.

5. Grease and establish a new sealing ring on a plate of the holder of a shaft. Priboltite a plate on the regular place on a head of cylinders.

6. Working in a similar manner (see paragraphs 4 and 5), establish the second camshaft in the head of cylinders.
7. Working as it should be, the return to a dismantle order, establish all remained components on the places. Check installation of valvate gaps, in case of need make their adjustment (see the Head Nastroyki and routine maintenance).
8. Start the engine and check it for existence of leak of oil through epiploons of camshafts. Let's the engine work within about five minutes on small turns for the purpose of removal of air from assemblies of proofreaders of valvate gaps. Make sure of serviceability of functioning of the unit.

The first five minutes after primary start the valvate mechanism will work with the increased noise. If noise level then does not decrease, it can indicate defect of one of proofreaders of valvate gaps.
