Installation

1. Install cylinder head cover.

Clean the sealing surface of cylinder head and
cylinder head cover to remove oil and sealing
materials completely.
Apply sealant (TB-1207B or equivalent) of bead
diameter 2-3 mm at eight place of arched area of
camshaft bracket on front and rear sides.

The cylinder head cover must be installed within 5
minutes after sealant application to prevent
premature hardening of sealant.
