Check

The lobby the centering directing guarantees unambiguity of installation of the driveshaft in relation to a transmission flange. Directing which впрессована to the canal in a forward part of the driveshaft, enters into connection with a directing finger on a transmission flange. Wear of the centering directing conducts to emergence of vibrations of a forward part of the driveshaft.

Sectional view centering directing (it is specified by an arrow).

For check centering directing give nuts and bolts of fastening of the elastic coupling to a transmission flange, grasp for the forward end of the driveshaft and try to move it up and down, and also in the parties. The shaft should sit densely on a finger of a flange of transmission. If is available appreciable люфт, replace a shaft.

Some driveshafts are equipped with a dustproof cover since the forward end, put on over the centering directing. This cover can be will bend or is deformed during shaft removal. Damage of a cover does not render influence on work of the centering directing - it is not necessary to confuse defect of a cover to wear of the most directing.

Replacement

 PERFORMANCE ORDER

  1. Remove the driveshaft (see. Section Removal and driveshaft installation).
  2. Fill the channel behind centering directing dense greasing so that greasing was up to standard of bottom edge of the directing. Insert in directing a metal core of suitable diameter (about 14 mm), cover directing with a piece of rags and knock on a core with a hammer (do not try to use a core of smaller diameter is will not work; greasing will be squeezed out from sides). Increase of hydraulic pressure of greasing at core immersion in it conducts to expression centering directing of the driveshaft.
  1. Grease new centering directing a disulfide - molybdenum greasing and press it in the driveshaft. Make sure that the isolating sponge of the directing comes out over a shaft surface approximately on 4.5 mm (size A).
  1. Establish the driveshaft (see. Section Removal and driveshaft installation).
