PERFORMANCE ORDER
1. Clear a back part of an insert and the place of its installation in a rod and a rod cover.
2. Establish inserts on the places.
3. One of methods consists in establishing covers of conrod bearings together with an insert on rods and to screw them the required moment. Measure the internal diameter of each collected couple of inserts of bearings. Measure diameter of each conrod neck of a bent shaft. Subtract the corresponding diameter of a conrod neck of a bent shaft from the measured diameter of the bearing.
4. The second and more exact method consists in using the product known as Plastigage. It is a round plastic core which contracts between an insert and a neck of a bent shaft. After removal of a cover of the conrod bearing the deformed plastic core is measured by a special template which is available complete with Plastigage. The procedure for Plastigage use following. Establish without lubricant rods on a bent shaft, necks of a bent shaft and inserts have to be absolutely pure and dry. Cut off several pieces of a plastic core and establish them on each neck of a bent shaft. Establish covers with the lower inserts and tighten fastening bolts the required moment.
5. In the course of measurement of a gap by Plastigage method do not rotate a bent shaft of the engine. Unscrew a cover of fastening of an insert, remove it and 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. In conclusion carefully clear Plastigage traces – material from inserts and a bent shaft.
