Timing Belt Tensioner: Testing and Inspection

INSPECT TIMING BELT TENSIONER





(a) Visually check tensioner for oil leakage.

HINT: If there is only the faintest trace of oil on the seal on the push rod side, the tensioner is all right. If leakage is found, replace tensioner.





(b) Hold the tensioner with both hands and push the push rod strongly against the floor or wall to check that it doesn't move. If the push rod moves, replace the tensioner.





(c) Measure the protrusion of the push rod from the housing end.

Protrusion: 8.0 - 8.8 mm (0.315 - 0.346 in.)

If the protrusion is not as specified, replace the tensioner.





INSPECT DRIVE BELT TENSION DAMPER

Compress and extend the tension damper rod and check that there is no abnormal resistance or unusual operation sounds. If there is any abnormality, replace the tension damper with a new one.





NOTICE: When discarding the tension damper, Use the following procedure.
^ Fully extend the damper rod.
^ Using a drill, make a hole in the cylinder as shown to release the gas inside.

CAUTION: The gas coming out is harmless, but be careful of the chips which may fly up when drilling.
