Check

Directing plugs of the valve

With the help a micromeasure and a calliper take readings of diameters of cores of valves and directing to check a gap between cores and directing. Do not forget to take readings from several places on all length of each core and directing. If the gap falls outside the limits norm, replace the valve and directing plug of the valve.

 PERFORMANCE ORDER

  1. Remove all deposit from valves.
  2. Check each valve on wear existence, прожога or deformations on a forward surface and a core and if it is necessary, replace it.

  1. Check an end face of a core of the valve about an ulceration and wear. If wear or an ulceration is found, the end face of a core of the valve can be cleared repeatedly, but is not strong, so that not сошлифовывать its chamber. If it is worn-out so strongly that its chamber is erased, replace the valve.
  1. Check each valve on existence of radial wear by means of the tsiferblatny indicator and the V-shaped block. Slowly rotate the valve to check wear. If wear exceeds norm limits, replace the valve. Limit of radial wear of a head of the valve: 0.08 mm (0.003 inches).

Width of contact of a prileganiye

  1. Create drawing of an arrangement of contacts on each valve habitually, i.e., having put a standard covering with a marking mix on a valve cup, and a rotary motion пристукнув a valve cup with a valve head. It is necessary to use the klapanny pritirochny machine (the tool used for grinding in of valves). The drawing printed on a contact surface of the valve should represent a continuous ring without any breaks, and the width of drawing should be in the specified limits. The standard width of contact formed by means of drawing of an arrangement of contacts on an obverse surface of the valve: on an admission and release — 1.1 – 1.3 mm (0.0433 – 0.0511 inches).

Repair of a cup of the valve

  1. The cup of the valve not creating complete contact to the valve or showing width of contact of a prileganiye, leaving for the specified range, should be repaired by a repolishing or cutting way and is ground to readiness by grinding in.
    • Cup of the exhaust valve: use a mill of a cup of the valve (1) to make two cuts. It is necessary to use two mills: the first to make a corner in 15 °, and the second to make a corner in 45 °. The second mill is necessary for using to receive necessary width of a cup. Width of a cup for a valve cup: 1.1-1.3 mm (0.0433 – 0.0511 inches).
    • Cup of the inlet valve: use mills of a cup of the valve to make three cuts. It is necessary to use three mills: the first to make a corner in 15 °, and the second to make a corner in 60 °, and a third to make a corner in 45 °. The third mill is necessary for using to receive necessary width of a cup. Width of a cup for a cup of the inlet valve: 1.1-1.3 mm (0.0433 – 0.0511 inches).
    • Grinding in of valves: grind in the valve to a cup in two steps: at first by means of rough structure of a mix of grinding in of an obverse surface, and then by means of small structure of the mix, each time using the machine for grinding in of nests of valves according to a standard method of grinding in.

 PERFORMANCE ORDER

  1. Remove all deposit from combustion chambers.

  1. Check a cylinder head about cracks in inlet and final channels, combustion chambers, and on a head surface.
  2. By means of a kalibromer check a planshetnost condensed a surface in 6 places. If the norm of deformation specified below, is exceeded, correct the condensed surface by means of a razmetochny plate and abrasive paper #400 (water-proof abrasive paper on the basis of silicon carbide): put paper on a razmetochny plate, and rub the condensed surface about paper, in order that сошлифовать high places. If it does not help to lower the indication of a kalibromer to norm limits, replace a cylinder head.
  1. Leakage of the working gases formed by products of combustion, from this condensed connection often occurs because of deformation of the condensed surface: such leak grows out of decrease in the made capacity. Limits of deformation of the condensed surface of a head of the cylinder: 0.05 mm (0.002 inches).

Deformation of surfaces of a prileganiye of a collector

  1. Check surfaces of a prileganiye of a head of the cylinder and collectors by means of a kalibromer, whether to define there is a need to correct these surfaces or to replace a cylinder head. Limits of deformation of surfaces of a prileganiye of a collector: 0.10 mm (0.004 inches).
