The wider arm must engage into the wider half of the sprocket.

-- Tension the tensioning tool with the thumb wheel until the tooth faces align.

-- Lay the camshafts and the camshaft bearings that are tied up with cable ties -arrows- onto the cylinder head.

NOTE:

The cable ties prevent the camshafts and the camshaft bearing from tilting when they are being tightened.

-- Check the camshaft "TDC" position:

The intake camshaft -2- must be able to be stopped with the Camshaft Adjustment PinsT40060.
The bolt -arrow- in the Camshaft Adjustment PinsT40060 must be perpendicular to the center axis of the camshaft.
The exhaust camshaft -1- must be positioned so that the groove -arrow A- runs parallel above the joint -arrow B- between the thrust bearing and the bearing cap.

-- Check the installed location of the alignment sleeves:

The intake camshaft -2- must be able to be stopped with the Camshaft Adjustment PinsT40060.
The bolt -arrow- in the Camshaft Adjustment PinsT40060 must be perpendicular to the center axis of the camshaft.
The exhaust camshaft -1- must be positioned so that the groove -arrow A- runs parallel above the joint -arrow B- between the thrust bearing and the bearing cap.

The rest of the installation is performed in reverse order of removal, noting the following:

-- Remove the Camshaft Fitting Tool - T40096T40096.

-- Install the camshaft timing chains. Refer to CAMSHAFT TIMING CHAIN, REMOVING FROM CAMSHAFTS .

CAUTION:

Risk of damaging valves and piston heads after working on valve train.

The motor must not be started for about 30 minutes after installing camshafts because the hydraulic equalization elements must seat themselves.
To ensure valves do not strike pistons when starting, carefully rotate engine at least two full revolutions.
