-- Remove the :T40271/2 .

-- Check the valve timing. The camshaft timing chain and cylinder head -arrows- must align with the markings on the chain sprockets -1-.

-- The markings for the camshaft timing chain and the camshaft timing chain guide rail -2- must align.

-- The notch on the vibration damper must align with the marking on the lower timing chain cover -3-.

-- Lubricate the hole -arrow- with engine oil.

Carefully attach the bearing mount, without tilting.

-- Mount the bearing bracket and the bolts -arrows- hand-tight.
