Toyota Avalon (XX50) 2019-2022 Service & Repair Manual: Installation

(a) Install a new cam timing control motor O-ring to the No. 2 timing chain cover assembly with the protrusion of the cam timing control motor O-ring oriented as shown in the illustration.

(a) Turn the cutout of the camshaft timing gear assembly eccentric shaft counterclockwise by hand, and set it to the maximum retard angle position.

• Make sure the contact surface of the cam timing control motor with EDU assembly (the surface that contacts the No. 2 timing chain cover assembly) is free of foreign matter.
• When installing the cam timing control motor with EDU assembly, do not use excessive force.
• If the cam timing control motor with EDU assembly has been struck or dropped, replace it.
