Skoda Felicia

1. Efficiency of return of the engine appreciably depends on correctness of adjustment клапанных backlashes. Excess of admissible size клапанных backlashes conducts to delay in operation of valves (too later opening and early closing). On the other hand, too dense landing of components is fraught with danger of loss компрессионного pressure as a result of incomplete closing of valves owing to thermal expansion of bars of pushers. Besides, in such situation there is an intensive burn-out of plates and saddles of valves.
2. Adjustment клапанных backlashes is made on the cold engine (backlashes of inlet and final valves at engine temperature +20°С should make 0.20 mm). In a case if bars of inlet valves are made of aluminium, instead of from a steel, a backlash it is necessary to establish 0.25 mm. Uncover heads of cylinders (engine Repair see the Head). For the purpose of simplification проворачивания a cranked shaft it makes sense to turn out also spark plugs (the Section Replacement of spark plugs - models 1.3 see).

3. For the purpose of providing of access to first two valves turn out a fixing bolt and remove the jellied mouth of impellent oil established under a cover маслоотражатель And. 4. The pusher of the valve subject to adjustment should rest against a heel of a corresponding cam of a camshaft (it is reached проворачиванием a cranked shaft). For convenience valves are numbered, beginning from drive ГРМ nearest to a chain. Adjustment is made according to the given numbering that allows to avoid superfluous проворачиваний a cranked shaft. The table with which help it is convenient to define an order of performance of adjustments is more low resulted:

The valve № 8 The valve № 1 (Вып) The valve № 6 The valve № 3 (Впускн) The valve №4 The valve № 5 (Вып) The valve № 7 The valve № 2 (Впускн) The valve № 1 The valve № 8 (Вып) The valve № 3 The valve № 6 (Впускн) The valve № 5 The valve № 4 (Вып) The valve № 2 The valve № 7 (Впускн)

5. The demanded sizes клапанных backlashes are resulted in Specifications. For adjustment performance ослабьте a wrench шестигранную a counternut of a spherical support коромысла. The support is thus kept from проворачивания by a screw-driver.
6. Enter an edge measuring probeа corresponding to requirements of Specifications of a thickness into a backlash between an end face of a core of the valve and a working surface коромысла its drive. Rotation of the adjusting screw of a spherical support achieve dense landing of an edge in a backlash. Having fixed a support in demanded position, tighten a counternut and repeat check.
7. In appropriate way turning a cranked shaft, repeat procedure for the remained valves in the order stipulated above.
8. Establish маслоотражатель and with demanded effort tighten a fixing bolt. Establish into place a cover of a head of cylinders and (if removed) spark plugs (the Section Replacement of spark plugs - models 1.3 see).
