Oil pump
Components
|
|
The rotating inhaling moment. |
Removal
|
|
Disconnect a negative cable from the battery.
Merge engine oil.
Remove an oil pan and a grid of the oil pump. Address the Section Oil pan and a grid of the oil pump in this Chapter.
|
|
Uncover an asterisk of the oil pump (1).
|
|
Remove the oil pump (2) from the pallet of a case (1).
|
|
|
Do not remove an asterisk from the oil pump. Otherwise the axis of the oil pump can be damaged that will lead to misoperation of the oil pump. |
|
|
Dismantling
Disassemble the oil pump.
|
|
1 — the case of the oil pump No. 1
2 — the case of the oil pump No. 2
3 — an external rotor
4 — the safety valve
5 — the counterbalancing spring
6 — a clamp |
Check
|
|
Check an external rotor, an internal rotor and cases of the oil pump regarding excessive wear or damage.
Check the safety valve regarding excessive wear or damage.
|
|
If any repair of an external rotor, internal rotor and to cases of the oil pump is necessary, replace them as uniform knot. |
|
|
Measure length of the counterbalancing spring of the oil pump in free and in the compressed state.
|
Technical characteristics of the counterbalancing spring of the oil pump
|
|
Norm
|
|
Spring length in a free state
|
63.5 mm (2.5 inches)
|
|
Spring loading
|
86.0 N for 52.0 mm
8.6 kg for 52.0 mm
62.2 pounds / 2.05 inch
|
Measure a gap between a rotor of the oil pump and the case of the oil pump.
|
|
Radial gap
Check a radial gap between an external rotor (2) and the case (1) by means of a kalibromer (4). If the gap goes beyond norm, replace an external rotor or the case. A limit of a radial gap between an external rotor and the case: 0.15 mm (0.0059 inches).
|
|
1 — the case
2 — an external rotor
3 — an internal rotor
4 — a kalibromer |
Side gap
By means of a ruler (5) and a kalibromer (4) measure a side gap. Limits of a side gap: 0.11 mm (0.0043 inches).
|
|
1 — the case of the oil pump No. 1
2 — an external rotor
3 — an internal rotor
4 — a kalibromer
5 — a ruler |
Installation
|
|
Wash, clean and then dry all sorted parts.
Apply engine oil with a thin layer on external and internal rotors, and the internal surfaces of the case of the oil pump.
Establish an external rotor in a pump housing No. 1.
|
|
Install the safety valve (3), the counterbalancing spring (2) and a clamp (1) in the case of the oil pump No. 2 (4). Fasten a clamp to the specified rotating moment. The rotating inhaling moment: a clamp of a spring of the safety valve of the oil pump (a) — 29 N • m (2.9 kg-m, 21.0 pound on foot).
|
Insert bolts of the case of the oil pump (5) into the case of the oil pump No. 2.
|
|
Collect the oil pump. And then be convinced that the rotor smoothly rotates a hand. The rotating inhaling moment: bolt of the case of the oil pump (a): 12 N • m (1.2 kg-m, 9.0 pound on foot).
|
|
|
Installation
|
|
|
|
Install the oil pump (2) on the pallet of a case (1) and fasten bolts with the specified rotating moment. The rotating inhaling moment: bolt of the oil pump (a): 27 N • m (2.7 kg-m, 19.5 pound on foot).
|
|
|
At installation of the oil pump be careful and do not drop bolts. |
|
|
Establish a cover of an asterisk of the oil pump (1), and fasten bolts with the specified rotating moment. The rotating inhaling moment: a bolt of a cover of an asterisk of the oil pump (a) — 11 N • m (1.1 kg-m, 8.0 pound on foot).
|
Establish an oil pan and a grid of the oil pump. Address the Section Oil pan and a grid of the oil pump in this Chapter.
Fill the engine with engine oil, having addressed the Section Engine oil and the filter in the Head Maintenance and lubricant.
Connect a negative cable to the accumulator.
Upon completion of installation check oil pressure, having started the engine. Address the Section Check of Pressure of Oil in this Chapter.
