PERFORMANCE ORDER
1. Remove a head of cylinders.
2. Check a head of the block of cylinders and the block of cylinders for straightforwardness of docking surfaces by means of a test ruler and the probe. The deviation from straightforwardness on all length of a surface should not exceed 0,04 mm; on length of 150 mm-0,015 of mm.
3. On a head of cylinders straightforwardness has to be checked on two surfaces: from the block of cylinders and from the camshaft.
4. Check straightforwardness of a head of cylinders on diagonals.

Prevention

5. If grinding of a head of cylinders was made, to check piston vystupaniye size (see table 2).
6. Establish a head of cylinders.
