Timing Belt Tensioner: Service and Repair

TIMING BELT TENSIONER

CAUTION: Compress the tensioner slowly, as damage to tensioner could result.

When tensioner is removed from the engine it is necessary to compress the plunger into the tensioner body.

CAUTION: Index the tensioner in the vise the same way it is installed on the engine. This ensures proper pin orientation when tensioner is installed on the engine.






REMOVAL
1. Place the tensioner into a vise and SLOWLY compress the plunger (Fig. 146). Total bleed down of tensioner should take about 5 minutes.
2. When plunger is compressed into the tensioner body install a pin through the body and plunger to retain plunger in place until tensioner is installed.


NOTE: For timing belt tensioner reset procedure, Refer to TIMING BELT - REMOVAL.


INSTALLATION
1. Hold the tensioner pulley against the belt and install the reset (pinned) timing belt tensioner into the housing. Tighten attaching bolts to 28 Nm (250 in. lbs.).
2. Remove tensioner retaining pin to allow the tensioner to extend to the pulley bracket.
