5. Install the compressed piston assembly back into the timing
chain tensioner body until it stops at the bottom of the bore.
See Figure 3. Note: Do not compress the piston assembly
against the bottom of the bore. This will activate the
tensioner, which will then need to be reset.
6. Measure the tension from end to end. It should measure
approximately 72 mm (2.83 inches). If it measures more
than this, the rachet cylinder in the piston assembly is not
fully compressed. Steps 2, 3, & 4 must be repeated until the
tension measures correctly.
CAUTION: To prevent personal injury, wear eye
protection that meets ANSI Z87.1 and OSHA standards.
