PERFORMANCE ORDER
1. Measure distance between the ends of a spring ring of fastening of a gear wheel on distributive to a shaft.
2. Mark and take pushers together with регулировоч ny plates.
3. Examine each pusher on existence of wear and scratches.
4. Check the working surfaces of bearings the distributor of ny shaft and contours of cams of camshafts for wear. With any wear replace the camshaft.

5. Using a micrometer, measure height of cams of camshafts...
6.... and diameters of necks of bearings of camshafts.
7. Check a working gap of bearings of the camshaft as follows.
7a. Clear covers of bearings and a neck of the camshaft.
7b. Install the camshaft in a head of the block of cylinders, at the same time do not establish pushers and do not grease the camshaft.
7 century. Cut off a piece of a plastic core of Plastigage (it has to be slightly shorter, than bearing width) and establish on a camshaft neck.
7 g. Establish a bearing cover, at the same time the arrow on a cover of the bearing has to be directed to a forward part of the engine.
7. Tighten bolts of fastening of a cover of the bearing of the camshaft the required moment and in stages.
Prevention

In the course of measurement of a working gap by Plastigage method do not rotate the camshaft.


7e. Unscrew bolts and uncover the camshaft bearing.
7zh. Apply a large-scale ruler to the deformed plastic core. Comparing width of the deformed plastic core to control width on a large-scale ruler, determine the size of a working gap.

7z. In conclusion carefully clear Plastigage-material traces from bearings and the camshaft.

8. Temporarily install camshafts without tolkata leu in a head of the block of cylinders and measure a side play between teeths of gear wheels of camshafts.
