Compression of springs at valve installation


The additional valve on Mitsubishi engines

On Mitsubishi engines of early releases the additional valve blocking a jet, screwed in the chamber of combustion and intended for formation of a stream of the gas mixture directed on a candle is provided to improve fuel combustion.

When dismantling a head of cylinders these valves should be removed first of all. The adaptation MD 998310 is for this purpose applied.

At a reversing of the valve of a jet the adaptation cannot be inclined, as cores of additional valves can be bent.


1. When dismantling compress a spring of the first valve by means of the suitable adaptation and remove crackers.
2. Release a valve spring, remove a plate of a spring, a spring and a basic washer.
3. Get the valve and remove a maslosjemny cap. Remove from valves a deposit.



Places of check of wear of the valve

And – places of check of wear of the valve in in an end face;

In – places of check of width of a corbel

Check of diameter of a core of the valve

Check of curvature of a core by rolling

Check of vertical position of a spring

Check of length of a spring

Width of a corbel of a head of the valve and landing corbel

1. Corbel of a head of the valve

2. Landing corbel

Attentively examine valves, check existence on facets of valves of cracks, traces of non-uniform development, ablation of metal and прогара. At development detection about an entrance in directing plug, ovality of end faces and reduction of width of a corbel against norms the valve replace.

Check length of springs and vertical position of springs (the deviation from a vertical no more than 2 ° is allowed). Springs with a usadka replace.

Check a gap of valves in plugs or on a difference of diameters of a core and the plug, or having shaken the valve in the plug. If the gap exceeds norm, the valve (or the plug) replace.

Define situation and width of a landing corbel, having greased a saddle with paint on a metal basis and having established the corresponding valve. If continuous, the valve and a saddle it is possible to use a corbel and further. If a trace faltering, it is necessary прошлифовать the valve and a saddle and to grind in the valve to a saddle.

Valve dismantling

For dismantling of the valve compress a spring, unscrew a nut and remove crackers

The worn-out additional valve changes assembled. For definition of its condition the valve can be disassembled (the adaptation) is required. If details in a satisfactory condition, replace only a maslosjemny cap of the valve.

Replacement maslosjemny cap of the additional valve

1. Cap

2. Case

After dismantling check wear of a core of the valve, at detection of traces of a burn-out and strong wear (is defined by rolling) the valve assembled replace. Collect the valve upside-down.

The additional valve of a jet before installation
1. New ring

2. To grease

At installation tighten the valve with the moment of 18-20 N of m.

Assembly of the klapanny mechanism

Napressovka of a cap


Assembly is carried out upside-down. Carefully remove the remains of a pritirochny material and wash out. Grease cores and напрессуйте new caps. All removed details establish on former places.
