NOTE
On release cars till 2001 for adjustment of gaps of valves adjusting washers, and on release cars since 2001 — the pushers having various thickness are used.

Cars till 2001 of release
If gaps of valves differ from demanded values, adjust them.
Turn a cranked shaft of the engine in situation at which camshaft cams over the valve demanding adjustment, will be directed up.

(fig. 2.51)
. Compress tool handles, thus the pusher of the valve will be drowned down, and establish between edge of a pusher and a camshaft an emphasis

. Remove the special tool for an utaplivaniye of a pusher of the valve. An edge of a screw-driver or tweezers take an adjusting washer and by a micrometer measure its thickness.

If gaps of valves differ from demanded values, remove a camshaft (or camshafts) and pushers. By a micrometer measure thickness of a head of a pusher
(fig. 2.53)
.
All models
Determine thickness of a new adjusting washer or a pusher head by a formula:
N= T + (And — V),
where And — the measured gap, mm;
N — settlement thickness of a new adjusting washer or a head of a pusher, mm;
T — thickness of the removed adjusting washer or a head of a pusher, mm;
V\nominal gap, mm.
Choose an adjusting washer or a pusher with the thickness closest to settlement.
In spare parts adjusting washers in thickness from 2,5 to 3,3 mm with a step of 0,05 mm, and pushers in thickness from 5,060 to 5,740 mm with a step of 0,020 mm are delivered.
Release cars till 2001
Turn a cranked shaft of the engine in situation at which camshaft cams over the valve demanding adjustment, will be directed up.
Establish the special tool for a pusher utaplivaniye on a camshaft from spark plugs over a valve pusher
(fig. 2.51)
. Compress tool handles, thus the pusher of the valve will be drowned down, and establish between edge of a pusher and a camshaft an emphasis
(fig. 2.52)
. Remove the special tool for an utaplivaniye of a pusher of the valve. An edge of a screw-driver or tweezers take an adjusting washer if it was not taken earlier. Instead of it establish a new washer. Again establish the special tool for an utaplivaniye of a pusher of the valve. Compress handles of the special tool and remove an emphasis.
By Shchup measure a gap in a valve drive.
Repeat operations on replacement of adjusting washers on other valves demanding adjustment of a gap.
Release cars since 2001
Establish pushers with settlement thickness of a head, previously having greased them with engine oil. Also put a butter layer on the internal part of a pusher contacting to a rod of the valve.
Establish a camshaft (camshafts).
All models
Establish a cover of a head of the block of cylinders, screw spark plugs and connect to them tips of high-voltage wires or the ignition coil.
