The oil pump in the disassembled condition (VR6): 1 — a bolt, always on replacement; 2 — a branch pipe маслоприемника; 3 — a lining, always on replacement; 4 — a bolt, 10 Н·м; 5 — an O-shaped sealing ring, always on replacement; 6 — a pump power shaft; 7 — the case of the oil pump; 8 — a bolt with internal шестигранником, 25 Н·м; 9 — gear wheels of the oil pump; 10 — a cover of the oil pump with редукционным the valve; 11 — заслонка редукционного the valve; 12 — a spring; 13 — screwed up заглушка редукционного the valve, 40 Н·м

At breakage the oil pump in most cases replace with the new. However it can be disassembled to check up and define, its details are worn how much out. As pressure of oil in the oil pump is created at the expense of rotation of the cogwheels linked among themselves in most cases it is possible to repair the pump, having replaced these cogwheels provided that the case of the pump is not damaged. In a pump cover it is located редукционный the valve which can cause malfunction. For pump dismantling, depending on engine type, be guided or fig. 166 (the engine 2,0), or fig. 170 (engine VR6).

Dismantling of the oil pump spend in a following order:

- Turn away bolts of fastening from the bottom and top part of the case of the pump and uncover the pump the pump case. On the 2,0-litre engine take out from a cover of the pump two short bolts;

- Turn away two bolts 1 (fig. 170) fastenings see and remove маслоприемник together with a lining 3 from the case 7 oil pumps of engine VR6. On the 2,0-litre engine the O-shaped sealing ring 11 (fig. 166 see) is used. It is necessary to replace a lining or an O-shaped sealing ring with the new;
