-- 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 direction of -arrow A- and push the :T40271/1 from the chain sprocket splines in direction of -arrow B-.
-- Remove the :T40271/1 .
-- Release the camshaft in the direction -C-, until the timing chain touches the guide rail -1-. Hold the camshaft firmly in this position, install the tensioning rail -2- 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 that the position of the colored chain link is aligned to the markings.
-- Remove the :T40271/2 .

Further installation is performed in reverse order of removal, while noting the following:
-- Install the :T10531/3 . In the "TDC point" the flat area -1- points upward. Install the :T10531/4 . Turn the crankshaft using a 32 mm open end wrench twice in the direction of engine rotation.
Due to the ratio, the painted chain links no longer match up after the engine has been turned.
