Timing Belt, Timing Belt Auto Tensioner Installation Note
1. Measure the tensioned rod projection length.
• If not as specified, replace the timing belt auto
tensioner.
2. Inspect the timing belt auto tensioner for oil
leakage.
• If not as specified, replace the timing belt auto
tensioner.
Projection (free length)
12.9—14.6 mm {0.508—0.574 in}
Caution
• Placing the timing belt auto tensioner
horizontally can cause oil leakage and
damage the timing belt auto tensioner. Place the timing belt auto tensioner vertically when using a
vise.
3. Verify the thrust of the timing belt auto tensioner
rod in the following order:
• If the timing belt auto tensioner rod is rigid
when it is pushed with a force of
approximately 235 N {24 kgf, 53 Ibf}, push it
down slowly and fix the pin in the hole.
• If there is no resistance on the timing belt auto
tensioner rod and it moves slightly when it is
pushed with a force of approximately 235 N
{24 kgf, 53 Ibf};
(1) Push it down slowly two or three times to the
bottom end of the rod.
(2) If the rod protrudes approximately 8.1 mm
{0.32 in}, verify that there is resistance on the
timing belt auto tensioner rod.
Caution
• To prevent damage to the inside of the
timing belt auto tensioner, do not press
down the timing belt auto tensioner rod
with a force greater than the specified
235 N {24 kgf, 53 lbf}.
Be careful that the rod does not touch the
bottom.
• If the timing belt auto tensioner rod
projection is restored, push it down slowly and fix the pin in the hole.
— If the resistance is not restored, replace the timing belt auto tensoner.
