4.8.5.3. Grinding of necks

Insignificant teases on necks can be smoothed out by whetstone of a carborundum of small granularity. If risks very deep or necks have ovality more than 0,05 mm, grind them.

Radical and conrod necks need to be ground, reducing their sizes by 0,25 mm to receive, depending on wear degree, the certain repair size specified in the tab. Sets of inserts of bearings of the repair sizes and repair sizes of necks of a bent shaft.

After grinding and the subsequent operational development of necks it is necessary to wash out well a bent shaft for removal of the remains of an abrasive. Several times to wash out channels for lubricant with remote caps gasoline under pressure. On the first cheek of a bent shaft it is necessary to specify the size of reduction of necks (0,25; 0,50 mm, etc.).

Ovality and conicity of radical and conrod necks after grinding have to be no more than 0,007 mm.
