2.30. Check and adjustment of gaps in valves

GENERAL INFORMATION

Prevention

Adjustment of gaps requires special adaptation for an otzhatiya of pushers of valves (see below).


Disconnect the battery from weight, blow compressed air and turn out candles. Uncover a head of cylinders (see subsection 3.1.4 or subsection 3.2.4). Install the piston of the 1st cylinder in compression step VMT.

4-CYLINDER ENGINES

Check of gaps in valves on 4-cylinder engines

On 4-cylinder engines check gaps of valves of the 1st cylinder, final valves of the 3rd cylinder and inlet valves of the 2nd cylinder.

Check of a gap between a cam of a cam-shaft and the valve by means of the probe

The probe has to pass under small effort.

PERFORMANCE ORDER
1. Measure by the probe gaps in valves. Write down those results which differ from norm.
2. Turn the crankshaft on 360 ° and combine tags. Check gaps of other valves.

ENGINES OF 3,0 L V6

PERFORMANCE ORDER
1. Install the piston of the 1st cylinder in VMT of a step of compression and measure by the probe gaps of the final valve of the 2nd cylinder and inlet valve of the 6th cylinder (IN – inlet, EX – final). Write down those results which differ from norm.
2. Turn the crankshaft on 120 ° and check gaps of the inlet valve of the 1st cylinder and final valve of the 3rd cylinder (1 – the right side, 2 – to a forward part of the engine, IN – inlet, EX – final).
3. Turning still the crankshaft on 120 °, check gaps of the inlet valve of the 2nd cylinder and final valve of the 4th cylinder (1 – the left side, 2 – to a forward part of the engine, IN – inlet, EX – final).
4. Turning further the crankshaft on 120 °, check gaps of the inlet valve of the 3rd cylinder and final valve of the 5th cylinder (1 – the right side, 2 – to a forward part of the engine, IN – inlet, EX – final).
5. Turn the crankshaft on 120 °, check gaps of the inlet valve of the 4th cylinder and final valve of the 6th cylinder (1 – the left side, 2 – to a forward part of the engine, IN – inlet, EX – final).
6. Turn the crankshaft on 120 °, check gaps of the inlet valve of the 5th cylinder and final valve of the 1st cylinder (IN – inlet, EX – final).

ENGINES OF 3,4 L V6

PERFORMANCE ORDER
1. Measure by the probe gaps in the specified valves (IN – inlet, EX – final, RH – the right side, LH – the left side). Write down those results which differ from norm.
.
2. Turn the crankshaft on 240 ° (2/3 turns) and check gaps in the specified valves (IN – inlet, EX – final, RH – the right side, LH – the left side). Measure gaps in other valves. Designate final or inlet valves on which measurements were carried out.

ALL ENGINES

PERFORMANCE ORDER
1. After measurement of gaps turn the crankshaft so that the cam of a cam-shaft of the first adjustable valve was turned from an adjusting washer aside.
2. Expose a groove on a pusher so that it was turned to a candle. Install adaptation and wring out a pusher, having squeezed handles of pincers of adaptation. Insert the holder devices and remove pincers (it is possible to reduce handles and to record them a hook, without using the holder).
3. Squeezing a pusher the holder, get adjusting washers, having hooked them the screw-driver or magnetic tweezers.

Prevention

On V6 3,4 engines of l of a washer of the 1 and 6 cylinders it is more difficult to get. Therefore reject adaptation from a cam-shaft of inlet valves a little aside.


4. Measure by a micrometer thickness of the removed adjusting washer, then determine the necessary thickness of remote laying by a formula (T – thickness of the removed laying, And – the measured gap, N – the required thickness of new laying, V – a standard gap): N = T + (A-V).
5. The manufacturer in the spare part delivers adjusting washers of 17 dimensional groups with thickness from 2,500 mm to 3,300 mm with a step of 0,050 mm. Pick up a washer so that its thickness was as it is possible closer to settlement.

Prevention

For economy it is possible to establish the washer suitable on thickness removed from the next valve.


6. Wring out a pusher adaptation and establish a new washer. Check a gap.
7. Repeat the described procedure for other valves. Establish all removed details upside-down.
