Chart of the choice of inserts

 

On early engines the top and lower inserts had identical thickness.

On late engines the working gap of the bearing was considerably reduced and in order that this condition was satisfied, apply four various inserts which are designated by a color tag at an end face. Color of a tag designates insert thickness. The top insert on all bearings has the identical size, and the working gap is regulated by installation of the lower insert of the required thickness.

On the latest engines new inserts can be chosen taking into account signs on the block of cylinders. In the absence of tags inserts can be picked up only by measurement of a working gap.

Tags on the block of cylinders are on the left side of the block, and tags of a bent shaft are at an end face of a crossing point of a bent shaft. These tags can be used for the choice of an insert of the required thickness as follows.

On cranked to a shaft and the block of cylinders there are two lines of identification: shaped a code which is used by Peugeot by production and a row from five designations. The first designation in the sequence belongs to the size number 1 of an insert. The last designation in the sequence (which is followed by an arrow) belongs to the size number 5 of an insert (see rice. Location of a mark in the block of cylinders and cranked to a shaft). Define number of designation from a certain neck of a bent shaft and an opening of the bearing of the block of cylinders.

On the top axis of the nomogram note designation of a bent shaft and through this point draw a vertical line. On the left vertical axis of the nomogram note designation of the block of cylinders and through this point draw a horizontal line. The point of intersection of lines specifies the insert size for providing the required gap (see rice. Chart of the choice of inserts).

For example, the nomogram shows that the bent shaft specifies 6, the block of cylinders indicates H, the point of intersection within red area defines that red (Class D) the most suitable for receiving the required gap.
