e8879fe5 Check of a working gap in bearings of a bent shaft

Bystry (and more exact) a method consists in using the product known as "Plastigauge". It consists of a round plastic core which contracts between an insert and a neck of a bent shaft. After removal of a cover and the lower insert the deformed plastic core is measured by a special template which is available in a set of "Plastigauge".

1. On the inserts installed in the block of cylinders of the engine establish a bent shaft without lubricant. Necks of a bent shaft and inserts have to be absolutely pure and dry.
2. To cut off several pieces of a plastic core of "Plastigauge" (they have to be slightly shorter, than width of the main bearings) and to establish them on each neck of a bent shaft.
3. To establish covers with the lower inserts and to tighten fastening bolts the required moment. In the course of carrying out measurement of gaps by Plastigauge method not to rotate a bent shaft.
4. To unscrew a cover of fastening of an insert, to remove it and to put 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, to determine gap size.
5. In conclusion carefully to clear all traces of Plastigauge-material from inserts and a bent shaft.
