— between the outer diameter of the conducted gear wheel and boring of the case of 0,12 — 0,2 mm;

— between teeths of gear wheels no more than 0,18 mm.

Install the oil pump as it should be, the return to removal. At the same time perform the following works:

— replace without fluctuation bolts with crosswise vents if they were broken;
