Removal and installation of camshafts and valves, assessment of klapanny gaps

Below the method of removal of valves from the removed head of cylinders is described. The removed components it is necessary to have so that then them it was possible will establish on former places. The repair sizes of components of a head of cylinders are specified in Specifications. Procedures of repair are not considered in view of their typicalness.


Damage of the cylindrical surfaces interfaced to pushers of valves is not allowed.


 PERFORMANCE ORDER

  1. Remove a head of cylinders (see. Section Removal and installation of a head of cylinders and natyazhitel of a driving chain).
  2. Remove covers of bearings of camshafts and take shaft from a head of cylinders.

In the last turn it is necessary to remove covers of the bearings closest to loaded pushers of valves.

  1. Take from a head of cylinders pushers and establish on their place protective caps not to damage cylindrical surfaces of a head of cylinders interfaced to pushers.
  2. Compress a klapanny spring by means of the special adaptation and remove from the valve crackers.
  3. Remove plates of a spring, a spring and a maslosjyomny cap.
  4. Take the valve from a head of cylinders.
  5. Measure the sizes of camshafts and components of the klapanny mechanism. If necessary replace defective parts.
  6. The damaged maslosjyomny caps replace.

Installation is made in return sequence. Before installation of pushers estimate klapanny gaps – in this case this distance from an end face of a core of the valve to a saddle of the bearing of a camshaft.

 PERFORMANCE ORDER

  1. For an assessment of a klapanny gap lay the special adaptation on saddles of two bearings of a camshaft. Make sure that щуп on the maximum length (20.5 mm) gets to a valve core, and on the minimum length (19.5 mm) does not get to it, i.e. the end face of a core of the valve should act on the size lying between lengths щупа (20.2 mm). Adjustment of a klapanny gap is made by means of machining of a core of the valve (if the result of measurement is lower minimum) or its saddles (if the result of measurement is higher maximum).
  1. Tighten covers of bearings, since near what cams are turned down.

Covers of bearings are numbered from 1 to 5 on the inlet party and with 6 to 10 on the final. Black bolts have the channel for greasing, and it is necessary to establish them from spark plugs.

  1. In summary level labels on camshafts with labels on covers of bearings.
