6.11.1. Removal

GENERAL INFORMATION

Sequence of removal of covers of bearings of a camshaft on the 4-cylinder engine
First of all covers of bearings No. 1, 3 and 5 (light shooters), and then covers of bearings 2 and 4 (dark shooters) act in film.

Sequence of removal of covers of bearings of a camshaft on the 5-cylinder engine
First of all covers of bearings No. 1, 2 and 6 (light shooters), and then covers of bearings 3, 4 and 5 (dark shooters) act in film.

Sequence of removal of covers of bearings of a camshaft on the 6-cylinder engine
First of all covers of bearings No. 1, 5 and 6 (light shooters), and then covers of bearings 2, 3, 4 and 7 (dark shooters) act in film.

PERFORMANCE ORDER
1. Remove a camshaft asterisk.
2. Check that covers of bearings of a camshaft are numbered, beginning from a driving chain.
3. Unscrew bolts of fastening of covers of bearings of a camshaft (see fig. Sequence of removal of covers of bearings of a camshaft on the 4-cylinder engine, Sequence of removal of covers of bearings of a camshaft on the 5-cylinder engine, Sequence of removal of covers of bearings of a camshaft on the 6-cylinder engine).
Prevention

Observe the follower a nost of unscrewing of bolts of fastening of covers of a camshaft in order to avoid camshaft damage.


Four-cylinder engines

PERFORMANCE ORDER
1. Gradually and evenly weaken bolts of fastening of covers of bearings of a camshaft No. 1, 3 and 5 and remove covers.
2. Gradually in diagonal sequence weaken bolts of fastening of the second and fourth covers of bearings of a camshaft on a turn half for each pass before complete unscrewing of bolts. It is necessary for gradual and uniform removal of pressure of klapanny springs on a camshaft.
3. Remove a camshaft from a head of the block of cylinders.

Five-cylinder engines

PERFORMANCE ORDER
1. Gradually and evenly weaken bolts of fastening of covers of bearings of a camshaft No. 1, 2 and 6 and remove covers.
2. Gradually in diagonal sequence weaken bolts of fastening 3, 4 and 5 bearings of a camshaft on a turn half for each pass before complete unscrewing of bolts. It is necessary for gradual and uniform removal of pressure of klapanny springs on a camshaft.
3. Remove a camshaft from a head of the block of cylinders.

Six-cylinder engines

Arrangement of a persistent half ring for adjustment axial люфта a camshaft

PERFORMANCE ORDER
1. Gradually and evenly weaken bolts of fastening of covers of bearings of a camshaft No. 1, 5 and 6 and remove covers.
2. Gradually in diagonal sequence weaken bolts of fastening 2, 3, 4, and 7 covers of bearings of a camshaft on a turn half for each pass before complete unscrewing of bolts. It is necessary for gradual and uniform removal of pressure of klapanny springs on a camshaft.
3. Remove a camshaft from a head of the block of cylinders.
4. Remove a persistent half ring регулиров ки axial люфта a camshaft from a back cover of the bearing of a camshaft (see fig. An arrangement of a persistent half ring for adjustment axial люфта a camshaft).
5. Take hydraulic pushers of valves from nests in a head of the block of cylinders. Arrange hydraulic pushers vertically in capacity with pure engine oil so that it was possible to establish them on the places.
