Subaru Legacy Service Manual: Installation

NOTE:

Be careful that the foreign matter is not into or onto the assembled component during installation.

Apply engine oil to all component parts of the timing chain.

1. Prepare to attach the chain tensioner.

(1) Insert the screw, spring pin and plunger into the tensioner body.

(2) As shown in the figure, turn the rubber mat counterclockwise while holding the chain tensioner from above by hand.

NOTE:

Degrease the contact surface between the plunger head and rubber mat, so that they do not slip.

(3) Insert the stopper pin into the hole on the chain tensioner body.

2. Align the position of oil pump shaft knock pin to six o’clock position as shown in the figure.

3. Using ST, align the “Top mark” on crank sprocket to nine o’clock position as shown in the figure.
