In the absence of access to a press the epiploon can be filled in a nest by means of a big vice with soft sponges. The holder with an epiploon have to be clamped between two flat wooden whetstones providing uniform distribution of loading on all area of a face surface of an epiploon. As a last resort, use of the hammer is allowed, however the zastukivaniye has to be made through flat wooden whetstone. Act slowly, you watch that there was no distortion.

On the considered engines the holder is put on the engine without laying, - instead it is necessary to impose a uniform pillow of RTV sealant on its interfaced surface. Do not forget to establish the directing pins on the regular places.
6. Having pressed the holder closely to the block, by hand acquire bolts of its fastening, make sure of correctness of installation of the holder, then tighten bolts with the required effort.
