3.16.21. Check of working gaps of radical bearings of a cranked shaft

PERFORMANCE ORDER
1. Clear back part of inserts and a place of their installation in blocks of cylinders.
2. For check of a working gap of the radical bearing use the Plastigage method. In this case the round plastic core which contracts between an insert 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 of Plastigage following. Establish without greasing inserts of radical bearings in section of the block of cylinders. Necks of a cranked shaft and inserts have to be absolutely pure and dry.
4. Install 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. Install the left block of cylinders and connect blocks of cylinders bolts, having tightened them the demanded moment.
5. In the course of measurement of a gap by Plastigage method do not rotate a cranked shaft of the engine.
6. Unscrew bolts of fastening of halves of blocks of cylinders and divide them.
7. Apply the large-scale ruler printed on packing to the deformed plastic core. Comparing width of the deformed plastic core to control width on a large-scale ruler, determine gap size.
8. In end carefully clear Plastigage-material traces from inserts and a cranked shaft.
9. Remove a cranked shaft from the block of cylinders.
10. Apply a thin film of engine oil on working surfaces of inserts of radical bearings.
11. Install a cranked shaft in the left block of cylinders.
12. Connect and fix bolts two sections of the block of cylinders.
