Vacuum Pump Removal Note

1.  When removing the vacuum pump, place a rag under the installation surface of the vacuum pump so that engine oil does not get on other parts.

2.  Remove the vacuum pump.


Vacuum Pump and O-ring Installation Note

1.  Rotate the vacuum pump by hand to drain the remainder of the engine oil in the vacuum pump.

2.  Degrease the O-ring installation groove and installation surface.

3.  Install the new O-ring to the vacuum pump.

Caution
•  When cleaning away the remaining silicone sealant on the cylinder head, insert a cloth into the oil passage and be careful not to allow silicone sealant to penetrate the oil passage. Otherwise, silicone sealant may penetrate the oil passage.
•  Use a cloth when blocking the oil passage. If a shop paper towel is used, pieces of the oil soaked towel may break off and enter the oil passage.

4.  Insert a cloth into the oil passage shown in the figure.

5.  Scrape the cylinder head from the inside to the outside using a scraper and clean away the remaining silicone sealant on the cylinder head so that it does not get in the cylinder head.

•  If silicone sealant gets in the cylinder head, blow it out using compressed air.

6.  Clean the cylinder head.

Caution
•  Be careful not to apply a large quantity of silicone sealant. Otherwise, the silicone sealant may overlap the O-ring of the vacuum pump and block the oil passage of the cylinder head.
•  Install the vacuum pump before silicone sealant dries.

7.  Apply silicone sealant (TB1217D or equivalent) to the positions shown in the figure.
