3.16.21. Check of working backlashes of radical bearings of a cranked shaft
PERFORMANCE ORDER
1. Clear a back part of loose leaves and a place of their installation in blocks of cylinders.
2. For check of a working backlash of the radical bearing use method Plastigage. In this case the round plastic core which is compressed between the loose leaf and a neck of a cranked shaft is used. After division of sections of blocks of cylinders the deformed plastic core is measured by a special template which is available complete with Plastigage.
3. Procedure of use Plastigage the following. Establish without greasing loose leaves of radical bearings in section of the block of cylinders. Necks of a cranked shaft and loose leaves should be absolutely pure and dry.
4. Establish a cranked shaft in the right block of cylinders. Cut off some slices of a plastic core and establish on each neck of a cranked shaft. Establish the left block of cylinders and connect blocks of cylinders bolts, having tightened their demanded moment.
5. In the course of measurement of a backlash by method Plastigage do not rotate a cranked shaft of the engine.
6. Unscrew bolts of fastening of halves of blocks of cylinders and divide them.
7. 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.
8. In end carefully clear traces of a Plastigage-material from loose leaves and a cranked shaft.
9. Remove a cranked shaft from the block of cylinders.
10. Apply a thin film engine oil on working surfaces of loose leaves of radical bearings.
11. Establish a cranked shaft in the left block of cylinders.
12. Connect and fix bolts two sections of the block of cylinders.
