Camshaft and its drive (VAZ-2121)

The camshaft of the 21213 engine differs from the 2121 in the different angular arrangement of the cams, since the 21213 engine has different valve timing. The camshaft drive has some peculiarities in repairing the chain tensioner. Its plunger 6 (Fig. 9-3) is not held from falling out of the housing 2 by a retaining ring (as on 2121 engines), and by punching the housing at three points B, To disassemble the tensioner, the edges of the housing should be filed at the punching points. After installing the plunger in the tensioner housing, it is necessary to punch the housing 2 at three points B. In this case, the projections from the punching should not touch the surface A when the plunger moves.
