  3. Wring out the check point from the engine and slowly lower down.

Installation

When replacing of any details or bolts established at the check point keep in mind the following: The case of the check point is made of magnesian or aluminum alloy. According to it these or those established details, such as a cover, and bolts are applied. If KPPP details from aluminum are established on the case from magnesian alloy, then the last will be exposed to corrosion. It belongs also to bolts of fastening of flange connection of the engine/check point. They have a special covering for the check point case from magnesian alloy. A check point sign from magnesian alloy is the inscription "Mg AL 9 Zn 1" from the lower side of the check point and around a stopper for filling with oil.
