Timing Belt Tensioner Adjustment

TOOL REQUIRED
- J 42069-10 Timing Belt Alignment Kit
- J 42069 Crank Hub Torx Socket
- J 42069-20 Checking Gauge

CAUTION: The following steps are the COMPLETION of installing and/or adjusting the timing belt and must not be performed as a stand alone operation.

1. With the Crankshaft Locking Tool in place locking the crankshaft at TDC:
a. Loosen the timing belt tensioner eccentric locking nut.





b. Turn the eccentric counterclockwise to full stop, then back until the reference mark is 2-4 mm ABOVE the reference mark on the flange. Tighten the timing belt tensioner locking nut to 20 Nm (15 ft. lbs.).
2. If the timing belt idler pulley bolts for camshafts 3 & 4 and 1 & 2 have not been previously torqued to specification. Tighten the timing belt idler pulley bolts while holding the eccentric in place with the Adjusting Wrench to prevent movement, to 40 Nm (30 ft. lbs.).
3. Remove all checking tools.
4. As a final inspection, once again rotate the engine in the clockwise direction two revolutions until reaching 60° BTDC.
5. Install the Crankshaft Locking Tool to the crankshaft drive gear with the knurled bolt.
6. Use the Crank Hub Torx Socket to carefully turn the crankshaft until the lever of the Crankshaft Locking Tool firmly contacts the water pump pulley flange.
7. Secure the moveable lever of the tool to the water pump pulley flange.
8. Inspect the alignment of the reference marks on the camshaft gears with the notches on the rear timing belt cover, as well as, the mark on the crankshaft gear with the mark on the oil pump housing.
9. Inspect the alignment of the marks on all four camshaft gears in reference to the marks on the Checking Gauge.
10. Repeat the procedure again if the marks do not align.
11. Continue with the engine reassembly as outlined in Timing Belt Replacement if further timing belt adjustment is not needed.
