Check a gap the calibrated plastic wire in the following order.
Uncover bearings.
Clear bearings and radical necks of a bent shaft.
Put a piece of the calibrated plastic wire 1 on the surface of a radical neck (parallel to a bent shaft) so that it did not close the oil channel.
Gradually tighten bolts of a cover of the bearing No. 1 1-10 and a cover of the bearing No. 2 11-20 as follows.

Fig. 2.166. Order of tightening of bolts of fastening of covers of bearings No. 1 and No. 2


and. Tighten bolts 1–10 moment of 30 N · m in the order specified in the figure 2.166.
b. In the same way, as well as when performing operation a), tighten their moment 50 N · m.
c. In the same way, as well as when performing operation a), tighten them for 60 °.
d. Tighten bolts 11–20 moment of 22 N · m in the order specified in the figure 2.166.

Inhaling moment
Bolt of fastening of a cover of the radical bearing of a bent shaft No. 1 (1-10): tighten the moment 30 N · m, 50 N · also tighten m on 60 °
Bolt of fastening of a cover of the radical bearing of a bent shaft No. 2 (11-20): tighten the moment 22 N · m.

NOTE
Do not rotate a bent shaft during measurement of gaps.

Uncover and determine gap size by flattening of the calibrated plastic wire 2 in the widest place, using a scale 1 on packing of the calibrated plastic wire.

Fig. 2.171. Measurement of the flattened piece of the calibrated plastic wire



If the gap exceeds its extreme value, replace the bearing. Always replace both inserts. The new bearing of the nominal size can provide a necessary gap. Otherwise, it will be necessary to proshlifovat a neck of a bent shaft and to use the bearing of thickness increased by 0,25 mm.
After selection of the new bearing check a gap again.

Gap in the radical bearing
Nominal rate: 0,025–0,045 mm.
Extreme value: 0,065 mm.

NOTE
After check of a gap in the bearing, make sure that deformation of bolts of a cover of the bearing No. 1 does not exceed extreme value.

Selection of the radical bearing of the nominal size
If the bearing is in an unsatisfactory state or the gap in the bearing – differs from norm, pick up and install the new bearing of the nominal size as follows.

Fig. 2.172. Marking of the radical bearing of a bent shaft


At first measure diameter of a neck of a shaft. As shown in the figure 2.172, on a cheek No. 2 of a bent shaft numbers are beaten out. There are three versions of numbers ("1", "2" and "3") which do not correspond to the following diameters of a neck of a shaft. Number on a neck of a bent shaft corresponds to diameter of a neck of a shaft designated by an arrow in the drawing. For example (M13 engine), No. "1" corresponds to diameter of a neck of a shaft – 44,9940–45,0000 mm.

Fig. 2.173. Marking of diameters of openings under radical bearings


Then, check diameter of an opening under the radical bearing. On the interfaced surface of the block of cylinders five letters, as shown in the figure 2.173 are beaten out. Three letters ("A", "B" and "C") correspond to the following diameters of an opening under the radical bearing. The letters on the block of cylinders specified in the drawing by an arrow correspond to diameter of an opening under radical the bearing.
For example (M13 engine), the letter "A" specifies that the corresponding diameter of an opening under the radical bearing makes 49,000–49,006 mm.

There are 5 classes of bearings of the nominal size differing on thickness. For difference they have color marking in the places shown in the figure 2.153.
Every color corresponds to a certain thickness of the central part of the bearing.

Thickness of the radical bearing of a bent shaft of the nominal size

According to number on a cheek of a bent shaft No. 2 and a letter on the block of cylinders pick up the new bearing of the nominal size for the table given below. For example (M13 engine) if number on a cheek of a bent shaft No. 2 – "1", and a letter on the block of cylinders - "B", install the new radical bearing of the nominal size with violet color marking.
Measure a gap of the radical bearing for the picked-up bearing of the nominal size.
If gap size still exceeds extreme value, install the bearing of the increased thickness and again check a gap.
When replacing a bent shaft or the block of cylinders assembled for any reason, pick up new bearings of the nominal size for No. at on new cranked to a shaft or letters on the new block of cylinders.
