Removal, check of a condition and installation of yokes and bars of pushers

Removal

 PERFORMANCE ORDER

  1. Uncover heads of cylinders (The section Removal and installation of a cover of a head of cylinders).
  2. Since a forward part of a head of cylinders, weaken in pairs bolts of fastening of yokes.
  1. In pairs weaken bolts of yokes of all inlet and final valves on 1/4 turns.
  1. Remove yokes, bridge brackets and spherical support of yokes, combine each of components in the separate capacity specially marked in relation to the valve together with the bolts. Bridge brackets can be established at assembly in any situation.

Components of yokes

And — the Bolt
In — the Bridge bracket
With — the Spherical support
D — the Yoke
  1. Remove bars of pushers and combine them separately that at assembly there was a guarantee of their installation on the former places.
  1. For the ordered storage of bars of pushers it is most convenient to make a special template of a cardboard box.

Condition check

 PERFORMANCE ORDER

  1. Check each of yokes on existence of signs of wear, cracks and other damages, special attention giving to the working surfaces contacting to bars of pushers and cores of valves. Examine saddles of spherical support in each of yokes and a surface of support. In case of detection of the protertost resulting fatigue deformation of cracks, traces of non-uniform wear or damages replace yokes together with support.
  2. Make sure of passableness of maslopodayushchy openings in end faces of bars of pushers and yokes.
  3. Check end faces of bars of pushers on existence of cracks and traces of excessive wear. Take for a drive each of bars on a flat surface (a large splinter of a windowpane) for identification of signs of a bend.

Installation

 PERFORMANCE ORDER

  1. Grease the bottom end faces of each of bars of pushers with pure impellent oil or assembly impellent greasing and establish bars on the former places. Make sure that bars completely "sat down" in nests of the pushers.
  2. Bring the piston of the first cylinder into the provision VMT of a step of compression (The section Reduction in the provision VMT of a step of compression of the piston of the first cylinder).
  3. Before establishing on places of a yoke grease end faces of cores of valves and the top end faces of bars of pushers with pure impellent oil or assembly impellent greasing.
  4. In order to avoid damage of contact surfaces during the first start of the engine till lifting of oil pressure grease spherical support of yokes with pure impellent oil or assembly impellent greasing. Establish yokes, their spherical support, bridge brackets and bolts on the former places. Tighten bolts with demanded effort.
  5. Establish into place a cover of a head of cylinders (The section Removal and installation of a cover of a head of cylinders).
  6. Start the engine, listen to the unusual sounds published by the klapanny mechanism and check a joint of a cover of a head of cylinders with a head on existence of traces of leakages of oil.
