18.104.22.168. Plugs of the roller of the drive of the oil pumpRemoval and installation of the plug of the roller of the drive of the oil pump of the engine of fashion. 2106
To check the internal diameter of plugs which has to make: for the forward plug – 48,084–48,104; for the back plug – 22,000–22,020. Maximum permissible wear of 0,15 mm. Also to check their press fitting in nests and coincidence of a lubricant opening in the forward plug with the channel in the block of cylinders (existence of a provorachivaniye of the plug).
For removal and installation of plugs at their replacement it is necessary to use a mandrel, observing the following:
– plugs have to be pressed in nests, at the same time the opening for oil in the forward plug has to be against the channel in the block of cylinders;
– plugs after a press fitting have to be finally processed and finished on internal diameter. To provide full coaxiality of plugs of a shaft, development which at the same time processes both plugs is applied to their operational development.
