Tools Required

Important: The following steps are the continuation of Timing Belt Replacement and must not be performed as a stand-alone operation.

Important: Whenever timing belt adjustment is necessary, always start with, and adjust, camshafts 3 and 4 first.

1. Apply the J 42069-20 to camshaft gears 3 and 4.
2. Inspect the relationship of the marks on the camshaft gears to the marks on the J 42069-20. They must match exactly, if not, timing belt adjustment is required.
3. Apply the J 42069-20 to camshaft gears 1 and 2.
4. Inspect the relationship of the marks on the camshaft gears to the marks on the J 42069-20. They must match exactly, if not, timing belt adjustment is required.
5. Continue to the next applicable procedure:

1. Loosen the timing belt idler pulley for camshaft gears 3 & 4.



2. Use the J 42069-40 to turn eccentric on the idler pulley COUNTERCLOCKWISE until the marks on the camshaft gears and on the J 42069-20 are in alignment (the high point of the idler pulley eccentric will be in approximately the 12 o'clock position).

Tighten
Tighten the timing belt idler pulley bolt, while holding the eccentric in place with the J 42069-40 to prevent movement, to 40 N·m (30 lb ft).
