2.29. Height of a core of the valve concerning a head of the block of cylinders
THE GENERAL DATA

Measurement of height of a core of the valve with the help скобы

1. THE MINIMUM BACKLASH BETWEEN СКОБОЙ AND THE TIP OF THE CORE OF THE VALVE IS EQUAL 0,38 MM (FLAT ЩУП IN THE THICKNESS 0,38 MM IS AVAILABLE IN REPAIR COMPLETE SET ВТ-3005 OF THE CARBURETTOR)
2. MEASURING СКОБА
3. PLACES OF OPIRANIJA СКОБЫ ON THE HEAD OF THE BLOCK OF CYLINDERS SHOULD BE SMOOTH AND PURE


The height of a core of the valve should not surpass certain value, fig. Measurement of height of a core of the valve with the help скобы see. For measurement of height of a core of the valve it is necessary to use adaptation DT12003 (measuring скоба). If the distance from an end face of a core of the valve to скобы is great, it is necessary in addition прошлифовать valve and saddle facets. If the valve height exceeds the admissible size, it is necessary to replace a head of the block of cylinders with saddles.
The prevention

It is forbidden to shorten a core of the valve grinding of a tip of a core.
