Oil pump for gasoline engines (Mazda CX-5KE)

Removal and installation the oil pump

Note.

: replace the part with a new one after each removal.

: apply oil.

Attention.

• A hot engine and engine oil can cause various burns. It is necessary to turn off the engine and wait until it cools down.
• A vehicle raised on a lift but not supported by safety stands is dangerous. It may jump off and fall, causing death or serious injury. Do not work around or under a raised vehicle that is not supported by safety stands.
• Prolonged skin contact with used motor oil can cause skin cancer. Wash your hands thoroughly with soap and water immediately after handling motor oil.
• If the camshaft is rotated after the drive chain is removed, the valves may hit the piston crown when the piston is at top dead center, causing engine damage. When rotating the camshaft with the drive chain removed, all pistons in the engine must be set to the middle position.
• When turning the camshaft with a wrench on the hexagonal part, the wrench may hit the rocker arm and damage it. To prevent damage to the rocker arm, when holding the camshaft by the hexagonal part, place the wrench closer to the rear of the engine, as shown in the figure, to ensure a safe gap between the wrench and the camshaft lobe.

Note: The width of the hexagonal part of the camshaft is 22-24 mm.
