2.4.8.6. Check of oil radial gaps

Uncover radical bearings and check radial oil gaps.

Fig. 2.325. Extraction of coupling bolts of fastening of covers of radical bearings


Evenly weaken and turn off eight coupling bolts of fastening of covers of radical bearings in several passes, as shown in the figure 2.325

Fig. 2.326. Extraction of bolts of fastening of covers of radical bearings


Then weaken and turn off sixteen bolts of fastening of covers of radical bearings in several passes, as shown in the figure 2.326.


Fig. 2.327. Removal of a cover together with the lower inserts and the lower persistent half rings


By means of the screw-driver separate and uncover together with the lower inserts and the lower persistent half rings (the last are established only in a zone of the radical bearing No. 2) (fig. 2.327).

Fig. 2.328. The scheme of the interfaced surfaces of a cover of the bearing and block of cylinders: 1 – the interfaced surfaces


Uncover the radical bearing, slowly shaking it here and there not to damage the interfaced surfaces of a cover of the bearing and the block of cylinders (fig. 2.328).

NOTE
You store covers of radical bearings together with the lower inserts not to mix them at installation.

Lift a bent shaft.
Clear each radical neck and inserts. Check the surface of each radical neck and inserts regarding existence of pointed corrosion and scratches. If the neck or an insert are injured, replace inserts. If necessary to a pereshlifuyta or replace a bent shaft.
