- J5590 Installer





1. Install the crankshaft balancer key into the crankshaft keyway. The crankshaft balancer key should be parallel to the crankshaft or with a slight incline.





2. Align the keyway of the crankshaft sprocket with the crankshaft balancer key.
3. Use the J5590 in order to install the crankshaft sprocket.
4. Rotate the crankshaft until the crankshaft sprocket alignment mark is at the12 o'clock position.

Important: Install the camshaft sprocket with the alignment mark at the 6 o'clock position.

Tighten the camshaft sprocket bolts to 25 Nm (18 ft. lbs.).
8. Install the crankshaft position sensor reluctor ring.
