Timing Chain Assembly: Installation
WARNING: This page is about a different variant/trim than selected.
NOTE:
- Be careful that the foreign matter is not into or onto assembled component during installation.
- Apply engine oil to the chain guide, chain tensioner lever and idler sprocket when installing.
- Prepare to attach the chain tensioner.
- Insert the screw, spring pin and tension rod into tensioner body.
- While depressing the tensioner onto rubber mat, twist it to shorten tension rod. Then insert the thin pin into the hole between tension rod and tension body to keep it.NOTE: Work on the rubber mat or other anti-skid materials.
- Using the ST, align the 'Top mark" on crank sprocket to 9 o'clock position as shown in the figure.
