Oil Pump Replacement
Removal Procedure
3. |
Remove the 8 oil pump cover
bolts (1). |
4. |
Remove the oil pump cover
(2). |
|
Warning:
Before removing the spring, cover the spring with
a towel to prevent the spring from flying and possibly causing
damage or personal injury. |
|
Note: Add the screw
driver between the oil pump slide spring windings (2).
|
5. |
Protect the engine front cover
edge (1) with a suitable piece of plastics. |
6. |
Compress the oil pump slide
spring with a screw driver and remove the oil pump slide spring in
compound with the oil pump slide spring pin. |
|
Note: Mind the
installation position of the oil pump components.
|
7. |
Remove the oil pump components
in the following order: |
|
7.1 |
Outer oil pump vane ring
(1). |
|
7.2 |
Oil pump vane rotor (3) and
the 7 oil pump vanes (2). |
|
7.3 |
Inner oil pump vane ring
(6). |
|
7.4 |
Oil pump slide (4) and the 2
oil pump slide seals with the 2 oil pump slide seal springs
(5). |
Cleaning And Inspection Procedure
1. |
Inspect the engine front cover
for cracks, scratches and damage. |
2. |
Inspect the oil pump cover and
the engine front cover for flatness. |
3. |
Inspect the oil pump vanes,
the oil pump vane rotor, the oil pump vane rings and the oil pump
slide for localized flatting. |
4. |
Inspect the oil pump slide
pivot pin for firm seat. |
|
Warning:
Wear safety glasses when using compressed air in
order to prevent eye injury. |
|
Caution: To
ensure proper engine lubrication, clean clogged or contaminated oil
galleries in an approved solvent and with compressed air. Failure
to clean oil galleries may cause engine damage. |
5. |
Clean the oil galleries with
solvent and compressed air. Blow compressed air from bore (2) to
bore (1). |
Installation Procedure
|
Note: Oil pump slide
spring pin and oil pump slide spring, as well as slide seal and
slide seal spring can be ordered as single parts. All other oil
pump components can only be ordered as a replacement kit.
|
1. |
Install the oil pan components
in the following order: |
|
Note: The bore (8) in the
oil pump slide must fit smooth-running and without clearance to the
oil pump slide pivot pin (7).
|
|
1.1 |
Install the oil pump slide
(6). |
|
1.2 |
Install the inner oil pump
vane ring (5). |
|
Note: Mind the installation
position of the oil pump vane rotor (4). The mark (9) must point to
direction of the oil pump cover.
|
|
1.3 |
Install the oil pump vane
rotor (4). |
|
Note: Mind the localized
flattings (3) on the oil pump vanes (2) caused by the oil pump vane
rings. The localized flattings must point to the oil pump vane
rotor.
|
|
1.4 |
Install the 7 oil pump vanes
(2). |
|
1.5 |
Install the outer oil pump
vane ring (1). |
2. |
Install the 2 oil pump slide
seals and the 2 oil pump slide seal springs (2) in the position as
shown to the 2 grooves (1) of the oil pump slide. |
3. |
Protect the engine front cover
edge (5) with a suitable piece of plastics. |
|
Note: The length of
the removed oil pump slide spring (2) should be 76.5 mm
(3.0118 in) for suction engines and 61 mm (2.4016
in) for turbo engines.
|
4. |
Install the oil pump slide
spring pin (1) in compound with the oil pump slide spring (4). Use
a scewdriver to compress the oil pump slide spring. The flat side
of oil pump slide spring pin must face upwards. |
5. |
Lubricate the oil pump vanes,
the oil pump vane rotor, the oil pump slide spring and the chambers
(3) with engine oil. |
6. |
Inspect the oil pump slide
spring mechanism for practicability. |
8. |
Install the oil pump cover (2)
and the 8 oil pump cover bolts (1). |
9. |
Tighten the oil pump cover
bolts in a sequence as shown to 8 N·m (71 lb
in) . |
10. |
Install the crankshaft
balancer (1) and rotate in shown direction (2) in order to inspect
the function of the oil pump mechanism. Crankshaft balancer should
rotate easily. |
