2.44. Backlashes in valves on the engine 1FZ-FE

Check and adjustment

Check and adjustment of backlashes in valves on the engine 1FZ-FE spend through each 96000 km, or every 4 year.

The prevention

Valves on this engine are regulated by selection of washers for a thickness, the special adaptation for отжатия pushers therefore is required.

For adjustment of valves of 6th cylinder it is required to remove cam-shafts. Therefore preliminary with special carefulness check up backlashes in these valves.

PERFORMANCE ORDER
1. Disconnect the battery from weight.
2. Turn out candles (subsection 2.28 see), uncover heads of cylinders and establish the piston of 1st cylinder in ВМТ a compression step.
3. Measure a backlash between a cam of a cam-shaft and a pusher in the specified valves, writing down each result.
4. At check of backlashes probe the given thickness should pass with small effort.
5. Turn коленвал on 1 turn rather ВМТ a compression step in 1st cylinder and measure backlashes in the valves specified in illustrations.
6. Having measured backlashes, turn коленвал so that the cam of a cam-shaft of the first adjustable valve has been turned upwards.
7. Wring out a pusher and get an adjusting washer. For this purpose establish the adaptation so that the long jaw of pincers of the adaptation grasped the bottom inflow under a pusher, and short rested against the top edge of the pusher. Compress pincers, push a small emphasis of the adaptation (or fasten a hook on handles of pincers), having fixed a pusher.
8. Clean pincers. Keeping a pusher, get an adjusting washer a screw-driver (a photo at the left) or magnetic tweezers (a photo on the right).
9. Measure by a micrometer a thickness of the removed adjusting washer.
10. Define a thickness of a remote lining at which the backlash in the valve will correspond to the standard:
N=Т + (А-V),
Т – a thickness of a removed adjusting washer,
And – a measured backlash,
N – a thickness of a new adjusting washer,
V – a demanded backlash (subsection 2.2 see).
11. The manufacturer in spare parts delivers adjusting washers of 17 dimensional groups. Pick up a washer so that the thickness of an established adjusting washer was as it is possible more close to settlement. It is possible to rearrange also the washer approaching on a thickness which have been removed from a pusher of other valve the backlash in which demands adjustment. It reduces number of got washers.
12. Wring out a pusher (see above) and establish a new adjusting washer.
13. Repeat procedure for other washers with which it is necessary to replace. Establish all removed details upside-down.
