3.1.10. Casing of the camshaft and camshaft


1. Remove a camshaft casing together with a head of cylinders (see subsection 3.1.12).
2. Remove laying of a casing.
3. Measure a free wheeling of the camshaft, having inserted the measuring probe between a persistent plate and shaft, if necessary replace a persistent plate. Unscrew two bolts of a persistent plate (are specified by shooters in the drawing at the left) and remove a persistent plate (the drawing on the right).
4. Take the camshaft from a casing.


1. Examine the surfaces of bearings in a camshaft casing on wear existence. If necessary the casing needs to be replaced.
2. Examine necks of bearings and cams of the camshaft. At wear detection, the shaft needs to be replaced. Examine a persistent plate of a shaft and replace it if necessary.


1. Establish a new epiploon of the camshaft.
2. Oil the camshaft and install it in a casing. Tighten bolts of a persistent plate and measure a free wheeling of a shaft.
3. Establish a camshaft casing.
