Installation

Sequence of a tightening of bolts of fastening of an inlet collector

Installation is made in sequence, return to removal, thus it is necessary to consider following moments:

  – Bolts of fastening of a head of the block of cylinders to replace with the new;
  – To establish only a new lining of a head of the block of cylinders;
  – On interfaced surfaces of an inlet collector and heads to put hermetic and bolts of fastening of an inlet collector to tighten in certain sequence;
  – To warm up the engine to working temperature and to check up installation of the moment of ignition;
  – To tighten bolts of fastening of an inlet collector in certain sequence.
