Baffle Plate - Tightening Specifications and Sequence





- Tighten baffle plate bolts to 9 Nm in sequence - 1 to 16 -.

Sealant Applied on Cylinder Block (for guide frame)





- Clean sealing surfaces, must be free of oil and grease.


The lubrication system could be plugged with excess sealant.

• Do not apply sealant bead thicker than indicated.

- Apply sealant beads - arrows - to the clean sealing surfaces as shown in the illustration.

• Thickness of sealant beads: 2.0 mm.

- Position seals - 1 through 4 -.

• The guide frame must be installed within 5 minutes after applying the sealant.
