Removal

PERFORMANCE ORDER
1. The special adaptation compress a spring of the valve and remove from a core of the valve crackers. Slowly release the adaptation compressing a spring, and remove a valve spring, a plate of a spring and the valve from a head of the block of cylinders.

The prevention

For storage of valves prepare the numbered polyethylene packages or containers.


2. Пассатижами remove маслоотражательный a cap.

The prevention

Do not use repeatedly маслоотражательный a cap.



Check

Valve spring


PERFORMANCE ORDER
1. Examine each spring of the valve on absence of cracks and damages.
2. Measure length of a spring in a free condition. Establish a spring on a flat horizontal surface and measure a deviation of the top part of a spring from a vertical plane.

Length of a spring a free condition: 42,03 mm
Length of a spring under loading of 24,7 kg: 34,5 mm
Maximum permissible deviation of a spring from a vertical plane – no more than 1,5


Directing plugs of the valve

Check up a backlash between a core and directing the valve. If the backlash exceeds maximum permissible value, replace directing plug of the valve with the plug of the increased repair size.

Backlash between a core and the directing plug of the valve:
Inlet the valve: 0,03–0,06 mm
Final the valve: 0,035–0,065 mm
Maximum permissible backlash between a core and the directing plug of the valve:
Inlet the valve: 0,1 mm
Final the valve: 0,15 mm

Valve saddle

Check up a condition and width of a working edge of a saddle of the valve. If necessary repair or replace a valve saddle.

Before replacement or repair of a saddle of the valve check up deterioration of the directing plug of the valve. If the directing plug of the valve is worn out, replace it.

Repair of a saddle of the valve is necessary for spending наждачным around or a mill. The width of a working facet of a saddle of the valve should be within technical requirements.



The valve


PERFORMANCE ORDER
1. Examine each valve on revealing of following defects:

– Damages or deformation of a core of the valve;
– Damages of a plate of the valve;
– Damages or non-uniform deterioration of an end face of a core of the valve.
2. If necessary, repair or replace the valve.

Thickness of an edge:

Inlet the valve: 1,1 mm
Final the valve: 1,4 mm
Maximum permissible thickness of an edge:
Inlet the valve: 0,8 mm
Final the valve: 1,1 mm


Installation

The prevention

Before installation clear all details.
Apply a thin film engine oil on all surfaces of sliding.


PERFORMANCE ORDER
1. Using the special adaptation 09222-22001, establish маслоотражательный a cap.
2. Grease a core of the valve with engine oil and establish the valve. At installation of the valve do not apply the big efforts not to damage маслоотражательный a cap.
3. Establish springs and holders of springs. Springs are necessary for establishing the party covered with enamel, to holders of springs.
4. The special adaptation compress a spring. Establish crackers and remove the special adaptation for spring compression.
5. Establish a head of cylinders.
