To remove the cylinder head, perform the following operations:
1. Remove the seven screws fastening the cover-stud head
cylinders, remove kryshkui disconnect the high-
voltage from the distributor to the spark plugs.
2. Turn the crankshaft clockwise to the position
in which the piston of the first position in TDC tsilindranahoditsya
the compression stroke (both valves closed), and the label 2 on the pulley
crankshaft is aligned with the edge of the pin sktanovochnogo
asterisks on the bottom cover drive mechanism timing
The first label (when reckoned in the direction of rotation
crankshaft) is used when installing the moment
ignition, and the second label
corresponds to the TDC.
3. Remove the eight bolts holding the top cover stars
and remove the cover (see "Removing and installing the top cover stars
Drive Timing ").
4. Remove the four screws fixing the driven sprocket drive
Timing and remove the asterisk from the shaft, not severing it from
chain (Fig. 9 and 10). In order to avoid jumping the chain with teeth
its stars, together with a chain link wire.
When disconnected the chain drive but not yet removed from the block
cylinder head, crankshaft, or can not carry through
camshafts in any direction, even at
very slight angle. Failure to do so
can cause damage to the valve head by
their xcontact with the bottom of the piston.
5. Remove the 10 nuts to remove the cylinder head
When removing the head rotate the crankshaft is unacceptable,
as by the friction of the rings mirror cylinder liners can
rise, and a hard face nazhny
shells hit scum or corrosion products block walls shirts
cylinders, the remaining water in the jacket after the block
drain the coolant.
This would violate the seal sleeve on the edges.
To avoid this, after removing the head liner to secure the block
Planck-holders mounted on the studs (11).
6. Remove the rubber sealing anchoring the cylinder head.
After checking and replacing worn and damaged parts
usianovka and fastening the cylinder head to block
in the reverse order.
1. Carefully inspect the head gasket
cylinders and rubber-cork under the head cover.
Damaged or badly crimped gasket replaced.
2. Cylinder head gasket prior to installation on
block brush on both sides of a special graphite lubricant for
protection from stick to
planes of the head and cylinder block.
3. For uniform compression across the surface lining
and warning of dangerous strains stud fastening nut block
Tighten the cylinder head in the sequence shown in Figure 12.
4. The final tightening nuts bolts fastening the head
cylinders produce a torque wrench, torque
9.0-10.0 kg * m
However, before you install the cylinder head must be
pre-set relative angular position
crankshaft and camshafts.
To do this, making sure that the preserved pre-
installation of the first cylinder piston at TDC
at the end of the compression stroke, rotate the camshaft until
As long as the risk on the flange of a camshaft
(Fig. 13) is established against the mid-tide
the front pillar of a camshaft.
POS of the cylinder head can be installed
on the cylinder block and mounted on it.
