REPAIR INSTRUCTIONS, PART 1
5. Align the punch marks on the camshaft gear
teeth to straddle the alignment hole in the
timing gear plate and install the camshaft
gear without the damper as shown in
Figure 300. Install the clamp plate tool,
J 44514-1A, using Position B of the gauge
plate tool to secure the camshaft gear to the
camshaft and loosely install the two
retaining bolts.

6. Insert the camshaft gear alignment tool,
J 47450-1, into the hole in the timing gear
plate while also engaging into the camshaft
gear teeth and place the rod of the tool in the
gauge plate slot. It may be necessary to
rotate the camshaft until this occurs. With
the camshaft gear alignment tool properly
positioned in the gauge plate slot, check that
the camshaft TDC mark is still positioned
between the two timing marks on the No. 7
camshaft bearing cap.

Sequence
Mark the bolts to aid in tightening the bolts to the
degree rotation specification.
8. Insert a 0.1 mm (0.004 inch) thickness
gauge on the pressure side of the adjustable
idler gear tooth and camshaft gear tooth by
using feeler gauge holder, J 44935 and
J 44514-6 feeler gauge. Tighten the bolts on
the adjustable idler gear by hand only.

9. Remove the feeler gauge from the gear
teeth.
10. Install the J 44514-5 clamp assembly tool to
the timing gear plate. Screw the hold-down
against the adjustable idler gear so the
adjustable idler gear does not rotate.
