| PERFORMANCE ORDER |
| 1. Put on pushers molybdenic greasing and establish them on places. |
| 2. Put molybdenic greasing on cams and necks of bearings of camshafts. |
| 3. Establish shaft in a head. Establish covers of bearings of shaft and insert bolts. |
| 4. Before installation do not forget to put hermetic on the surface which was joined to a head of the first cover. |
| 5. Using the specified sequence, tighten bolts of covers in stages (on 1/4 turns) (see fig. Sequence of a tightening of bolts). |
