3.3.17.2. Check of a working backlash of bearings THE ENGINE OF SERIES XU

PERFORMANCE ORDER
1. On early models of engines at major repairs it is necessary to establish new loose leaves. On later models of engines the control of a working backlash can be executed with use of initial loose leaves. However it is preferable to use a new set as the received results will be more exact.
2. Clear a back part of the loose leaf and a place of its installation in the block of cylinders and covers of radical bearings.
3. Establish loose leaves on the places. Pay attention that the top loose leaves of the bearing have a working surface with a flute, and the bottom loose leaf has a continuous working surface.
4. The working backlash can be checked up two methods.
5. One of methods (which presence of a micrometer for measurement of diameter of apertures assumes) consists in establishing covers of radical bearings together with the loose leaf on the block of cylinders and to screw their demanded moment. Measure internal diameter of each collected pair loose leaves of the bearing. Measure diameter of each radical neck коленвала. Subtract from the measured diameter of the bearing the corresponding diameter of a radical neck коленвала.
6. The second (and more exact) a method consists in using a product known as Plastigage. It is a round plastic core which is compressed between the loose leaf and a neck коленвала. After removal of a cover of the radical bearing the deformed plastic core is measured by a special template which is available in complete set Plastigage. Procedure for use Plastigage the following.
7. On established in the block of cylinders of the engine loose leaves establish without greasing коленвал. Necks коленвала and loose leaves should be absolutely pure and dry.
8. Cut off some slices of plastic core Plastigage (they should be slightly shorter, than width of the main bearings) and establish them on each neck коленвала.
9. Establish covers with the bottom loose leaves and tighten bolts of fastening by the demanded moment. In the course of measurement of a backlash by method Plastigage do not rotate коленвал.
10. Unscrew a cover of fastening of the loose leaf, remove it and to the deformed plastic core put the scale ruler printed on packing. Comparing width of the deformed plastic core with control width on a scale ruler, define backlash size.
11. In end carefully clear traces Plastigage of a material from loose leaves and коленвала.
