Dismantling of a head of cylinders

The new or restored head can be ordered on HUNDRED Opel or from a warehouse of the manufacturer. Whereas at carrying out of dismantling and check of a condition of a head some difficult and expensive adaptations be required, probably will get more cheaply the new or restored head.

At a corresponding complete set right after head removals take from the block of the engine a jet () oil dispersions, clean it (them) and combine in a separate polyethylene package.

Dismantling of a head of cylinders demands preliminary dismantle клапанного the mechanism (inlet and final valves with accompanying components). It is meant that levers of a drive of valves and a camshaft () are already taken from a head (ок).

 PERFORMANCE ORDER

  1. Remove a head of cylinders from the engine block (the Part of Procedure of repair of petrol engines SOHC without their extraction from the car, Procedure of repair of petrol engines DOHC without their extraction from the car or Procedure of repair of diesel engines without their extraction from the car of the present Chapter see).
  2. By means of the special tool compress a spring () the first valve and take from a flute on a core crackers of the cutting lock of a plate (take advantage of a magnetised core, корнцангом, or nippers). Cautiously release the tool and remove from the valve a spring plate, a spring (), маслоотражательный a cap and a spring saddle (depending on a complete set) On engines SOHC of release till September, 1995 remove also duplicators.
Compression клапанной springs of engines SOHC of 1.0 and 1.2 l
Compression клапанной springs of engines DOHC of 1.4 and 1.6 l. Spring compression on diesel engines is made similarly
Removal маслоотражательного a cap

If crackers "have become attached" and do not give in to extraction, slightly knock with a hammer on the tool for сжимания springs from outside a clamp.

  1. The removed components клапанной assemblages combine in the separate accurately numbered polyethylene package / a plastic glass.
  2. Further, take the valve, having pushed it in the combustion chamber. If there is a valve jamming in the directing plug, push it back in a head and оселком or a file with a small tooth accurately smooth out flute edges under installation of crackers.
  3. Operating in a similar manner, dismantle remained клапанные assemblages. Put removed components of each of valves in the separate package/glass equipped with corresponding marks, - at assemblage each detail should be established strictly on the former place.
  4. After all components клапанного the mechanism will be taken and combined in the organised order, it is possible to start performance of procedures of cleaning and check of a condition of a head (at full-scale regenerative repair of the engine before finish its dismantling).
