i.

Clean the inside surface of the end cover.


ii.

Install a new vacuum pump cover O-ring to the vacuum pump housing.

NOTICE:
·

Wipe off any oil on the end cover installation surface and end cover.

·

Check that no foreign matter is on the vacuum pump cover O-ring or inside the vacuum pump housing.




iii.

Using a T30 "TORX" socket wrench, install the end cover with 5 new screws.

Torque:
7.5 N*m (76 kgf*cm, 66 in.*lbf)

NOTICE:
·

Hold the pump so that the pump installation surface and fitting parts will not be damaged.

·

As the housing deforms when force is applied, do not secure the housing with a tool such as a vise.

·

Securely fit the T30 "TORX" socket wrench to the screws.

*a Correct *b Incorrect


i.

While looking from the coupling side of the vacuum pump assembly, rotate the coupling clockwise.

Standard:

Rotates without locking.


NOTICE:
·

As the vacuum pump vane cap may become damaged, do not rotate the coupling counterclockwise.

·

Even if rotation fluctuates between heavy and light, it is not a malfunction unless the coupling locks.
