3.14. Replacement of maslootrazhatelny caps of the mechanism of gas distribution

 PERFORMANCE ORDER

We turn out a candle key from a head of the block of cylinders of a spark plug.
We uncover heads of the block of cylinders (see Replacement of laying of a cover of a head of the block of cylinders).
We turn a bent shaft until coincidence of a tag on its pulley with a tag on a camshaft drive cover.
We remove the case of the camshaft and levers of the drive of valves (see Removal of the camshaft and levers of the drive of valves of the vpryskovy engine, Removal of the camshaft and levers of the drive of valves of the carburetor engine). In this provision of a bent shaft (pistons of the 1st and 4th cylinders are in VMT) we change maslootrazhatelny caps of valves of the 1st and 4th cylinders.

Through a candle opening we insert between the bottom of the piston and a plate of the valve (on which we change a cap) a bar from soft metal, with a diameter about 8 mm.

We establish a rassukharivatel of valves.
The thrust bearing of a rassukharivatel is rested against a plate of the valve, and zatsepny the lever is started for a nut, navernuty on a hairpin of fastening of the case of bearings of the camshaft.

We squeeze a rassukharivatel of a spring of the valve...

... also we take nippers (or tweezers) crackers.

We weaken springs.

We remove a plate of the valve...

... external and internal springs...

... and also top and lower basic washers of springs.

Nippers removed a maslootrazhatelny cap from the directing valve plug.

In the absence of nippers we hook two screw-drivers a maslootrazhatelny cap and we remove it.

We carry out operation carefully not to damage the fragile directing plug.

Having greased a working edge of a new maslootrazhatelny cap with engine oil, accurately we put on it a valve core.

Through a high head "on 12" or a mandrel napressovyvay a cap on the directing valve plug.

We assemble the valvate mechanism in the return sequence. We take a bar from a candle opening. After replacement of maslootrazhatelny caps of valves of the 1st and 4th cylinders, we turn a bent shaft on 180 ° (supporting a camshaft drive chain so that not to jam it) and we change caps of valves of the 2nd and 3rd cylinders.
Assembly of the mechanism of gas distribution is carried out in the return sequence. On the carburetor engine we regulate a tension of a chain and thermal gaps in the drive of valves.
