Assembly

Assembly is made as it should be, the return to a dismantle order.

Replacement of sealing rings, remote plugs, epiploons, lock rings and washers should be made without fail each time when dismantling the steering mechanism. It means that for performance of assembly of the mechanism it is necessary to get the special remnabor containing all necessary replaceable components.


 PERFORMANCE ORDER

  1. Before assembly grease all components with hydraulic liquid.
  2. Grease with suitable hermetic a new epiploon of a back cover and establish and plant it in a case of the steering mechanism by means of the piece of a pipe leaning on external perimeter of an epiploon. Track, that the epiploon appeared will turn the main sponges to the intensifying piston.
  3. Establish in a back cover new sealing and teflon rings. For temporary fixing grease rings with technical vaseline.
  4. Establish in a case of the steering mechanism a worm shaft, the intensifying piston and a back cover. Try not to damage a teflon ring at a piston end face. Track that all sealing rings were established on the places.
  5. Screw bolts of fastening of a back cover and tighten them in a diagonal order in two-three stages with final effort of 26 ÷32 of Nanometer.

The intensifying piston should be in normal working situation and not to be warped.

  1. Grease a new epiploon of a sector shaft outside on perimeter with suitable hermetic, then plant it perpendicularly in a case of the steering mechanism by means of a piece of a pipe which should rest against the external region of an epiploon. Moderately grease are flexible an epiploon technical vaseline.
  2. Establish in a case of the steering mechanism the big remote plug and fix it a lock ring. Track, that the lock ring appeared is turned by the rounded edge to an epiploon.

On some models the epiploon party with the rounded edge is marked with an identification label in the form of R letter.
