4.8.6.3. Check of details of the pump


Check of a radial gap in the oil pump



Check of a vystupaniye of a gear wheel for the plane of the case of the oil pump


After dismantling all details of the pump should be washed out kerosene or gasoline, to blow a stream of compressed air, and then to examine the case and a cover of the pump; in the presence of cracks of a detail to replace.

To check a set of probes gaps between teeths of gear wheels, and also between outer diameters of gear wheels and walls of a pump housing (fig. Check of a radial gap in the oil pump) which have to be respectively 0,15 mm (maximum permissible 0,25 mm) and 0,11–0,18 mm (maximum permissible 0,25 mm). If gaps exceed extreme values, then to replace gear wheels, and if necessary and a pump housing.

The probe and ruler to check a vystupaniye of gear wheels for the pump housing plane (fig. Check of a vystupaniye of a gear wheel for the plane of the case of the oil pump). It has to be equal to 0,05-0,135 mm (minimum admissible 0,02 mm). If vystupany less than 0,02 mm to replace gear wheels or a pump housing depending on what underwent wear.

Having measured details, to define a gap between the conducted gear wheel and its axis which has to be 0,017 0,057 mm (maximum permissible 0,1 mm), and also between the roller of the pump and an opening of the plug of the case which has to be 0,016–0,055 mm (maximum permissible 0,15). If gaps exceed extreme values, to replace worn-out details.
