Check and adjustment of backlashes of valves

Adjustment клапанных backlashes is made on the cold engine!

The petrol engine

For performance of the given procedure special tools which can be got in the services-centres of company Toyota, firm shops of automobile accessories and in the wholesale markets be required.


If backlashes in клапанном a drive are great, valves will enough not open. The drive will be noisy and the engine will be bad for pulling, as there will be an incomplete filling of cylinders by a working mix. Final valves will open insufficiently for ventilation of the cylinders, the remained pressure of gases will interfere with receipt of a new charge of a mix in the cylinder. If backlashes are too small, inlet and final valves will not sit down in saddles densely at closing. It will worsen a heat-conducting path from нагретых valves to a head. Thanks to it the engine also will lose draught (there will be a leak of gases), valves will overheat and burn through.

Adjustment of backlashes in клапанном a drive is made by selection of adjusting washers of a certain thickness which are established in pushers of valves. At manufacturing the drive of valves has some disorder within admissions, therefore at adjustment of backlashes it is required to establish the washers, a bit different in the thickness from each other. Company Toyota lets out repair washers of a different thickness with step of 0.02 mm. For carrying out of correct adjustment of backlashes in клапанном a drive necessary adjusting washers can be got at the dealer of company Toyota.

For carrying out of the given procedure specialised tools Toyota are required. For отжимания a pusher to receive a sufficient backlash for washer replacement (the spring is thus compressed клапанная) the tool similar on big клеши is applied. To pusher fixing in this position it is applied рычажок, established враспор between a pusher and a camshaft. For washer removal apply the magnetic tool, to exact measurement of its thickness – a micrometer. It is not recommended to spend backlash adjustment if there are no such tools.

Adjustment of valves, certainly, should be it is spent as it is possible more precisely, however, if there is no other possibility, it is better to leave a backlash in a drive slightly increased, than "pressed" as in the latter case valves can burn through. It is better to have the a bit noisy engine, than faulty.

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped by a security code before to disconnect the battery make sure that have a correct combination for audiosystem input in action!

2. Empty cooling system.
3. Disconnect coils from spark plugs and remove the other components, covers of a head of cylinders stirring to removal.
4. Blow candle niches and turn out spark plugs (the Section Check of a condition and replacement of spark plugs (petrol engines) see).

At use of compressed air do not forget to put on goggles!

5. Uncover () heads (ок) cylinders (the Engine see the Head).
6. Result the piston of the first cylinder in position ВМТ of the end of a step of compression (the Engine see the Head).
7. With the help щупов лезвийного type make measurement of backlashes of the valves specified on an accompanying illustration.
8. Turn a cranked shaft on one complete revolution in a normal direction and make measurement of backlashes of the remained valves (address to an accompanying illustration).

Adjustment

 PERFORMANCE ORDER

1. Having finished measurements, compare them to requirements of Specifications.
2. On the engine 2UZ-FE remove a camshaft (the Engine see a corresponding part of the Head).
3. By means of a micrometer measure a thickness of the taken adjusting washer. For definition of a thickness of a new washer make following calculations:
N = Т + (AND – V)
Where:
Т = the Thickness of an old adjusting washer
And = Size of the measured backlash
V = the Demanded size клапанного a backlash
N = the Demanded thickness of a new adjusting washer (Specifications see).
4. Pick up a new adjusting washer of the thickness allowing as more as possible precisely to approach клапанный a backlash to demanded value. Adjusting washers of 41 standard sizes in a range from 2.000 to 2.800 mm (№№ from 00 to 80) with step of 0.020 mm are issued.

In certain cases removed from a pusher of one valve the old washer can approach for installation on a pusher of another, requiring adjustment, the valve, do not hasten to get replaceable washers.

5. Establish on a pusher the picked up adjusting washer. By means of measuring щупа a corresponding thickness make sure of correctness of the made updating.
6. Operating in a similar manner, make adjustment of all valves with the broken backlash.
7. Establish to the place of a spark plug, a cover () heads (ок) cylinders, protective covers, an arm of a cable of an accelerator and other, acting in film for the purpose of providing of access, components.

Check

 PERFORMANCE ORDER

1. Remove air lines and a cover of a head of cylinders.
2. Translate the piston of the first cylinder in ВМТ. For this purpose, rotating a cranked shaft clockwise, combine adjusting labels (address to an accompanying illustration). Thus cams of a drive of valves of the first cylinder should be turned upwards, otherwise turn a cranked shaft on one turn. Make sure that коромысла valves of the first cylinder are free, and коромысла valves of the cylinder №6 are tightened.
3. Measure a backlash between the adjusting screw коромысла the valves specified on an accompanying illustration and the lever of a drive of the valve.
4. Turn a cranked shaft on one turn and measure a backlash on other valves.
5. Compare results of measurements to requirements of Specifications and if necessary adjust клапанные backlashes.

Adjustment

 PERFORMANCE ORDER

1. Ослабьте a counternut on the lever of a drive of the valve (1) also turn out the adjusting screw (2) so that last and a valve core have appeared completely separated (address to an accompanying illustration).

Thus keep the lever of a drive of valves an adjustable spanner.

2. Ослабьте a counternut the adjusting screw on коромысле.
3. Insert щуп лезвийного type between the adjusting screw on коромысле and the lever of a drive of valves. For Inlet valves use щуп in the thickness of 0.20 mm, and for final – thickness of 0.50 mm.
4. Turn the adjusting screw in коромысле until at moving щупа small resistance then fix the adjusting screw a counternut (address to an accompanying illustration) will not be felt.
5. At inserted щупе check up that resistance to its moving does not vary at easing of the adjusting screw on the lever of a drive of valves. Otherwise return to paragraph 2.
6. Tighten the adjusting screw on the lever of a drive of valves and fix its counternut when resistance щупа will amplify.

Thus keep the lever of a drive of valves an adjustable spanner.

7. Ослабьте a counternut on коромысле.
8. Move the adjusting screw while щуп will not start to move with very small resistance then fix the adjusting screw a counternut.
9. Establish a cover of a head of cylinders and earlier dismantled details.
