Camshaft Timing Chain, Removing From Camshafts: Installing

• The vibration damper is at the "TDC" point.
• The notch on the vibration damper must align with the arrow marking on the lower timing chain cover -arrow-.

• Camshaft chain sprockets fixed with :T40271/1  and :T40271/2  .
• The markings previously made on the camshaft chain sprockets -arrow- are flush to the camshaft locks.

-- Position the markings on the chain links -arrows- at the chain sprockets -1- to mount the camshaft timing chain.

-- Install the upper guide rail -2-.

With Wrench Clearance: 

The help of a second technician is necessary for the following step.

-- Turn the exhaust camshaft in direction of -arrow 1-, slide the :T40271/1  out of the chain sprocket splines in direction of -arrow 2-.

-- Carefully release the camshaft, until the camshaft timing chain is laying on the upper guide rail. Hold the camshaft in this position.

-- Bring the camshaft timing chain tensioning rail into the installation position, and tighten the bolt -A-.

-- Remove the :T40271/1  .

Without Wrench Clearance: 

The help of a second technician is necessary for the following step.

-- Turn the exhaust camshaft with the :T10172A  slightly in the direction of -arrow A- and push the :T40271/1  from the chain sprocket splines direction of -arrow B-.

-- Release the camshaft carefully in direction -arrow C-, until the camshaft timing chain touches the guide rail -1-. Hold the camshaft in this position.

-- Bring the camshaft timing chain tensioning rail -2- into the installation position, and tighten the bolt -3-.

All Versions: 

-- Turn the intake camshaft in direction of -arrow 1-, slide the :T40271/2  out of the chain sprocket splines in direction of -arrow 2- and release the camshaft.

-- 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.

-- Depending on the version, remove either the :T40011  or the :T40267  .

-- Tighten the bolts -arrows-. Refer to OVERVIEW - CAMSHAFT TIMING CHAINS .

-- Install the bolt -arrow-.

-- Install the control valve -item 6-  OVERVIEW - CAMSHAFT TIMING CHAINS.

Further installation is performed in reverse order of removal, while noting the following:

-- Install the upper timing chain cover. Refer to UPPER TIMING CHAIN COVER, REMOVING AND INSTALLING .

There are additional procedures depending on the model. Refer to CHAIN DRIVE .
