REPAIR INSTRUCTIONS
Page 245
There are 45 gear teeth on the crankshaft gear,
90 teeth on the camshaft gear and 48 on the idler
gear. Because the idler gear has 3 more teeth
than the crankshaft gear, the timing marks align
only once every 16 revolutions of the crankshaft.
This is called a “hunting tooth” system.
3. Slide the idler gear onto the hub assembly
with timing marks facing out.
4. Position the idler gear timing marks so they
align (Figure 265) with the crankshaft and
camshaft gear timing marks. Then slide the
idler gear/hub assembly into position on the
cylinder block.

5. Oil the bolts with clean engine oil. Start the
bolts a few turns.
6. Tap the hub portion of the assembly with a
brass hammer to seat the components.
7. Tighten the bolts evenly to specification. Do
not use an impact wrench or other air tool to
tighten bolts.
Auxiliary Shaft Installation
[212 CV]
Before installing the auxiliary shaft in the engine,
ensure that the shaft is clean, undamaged and
well-lubricated with clean engine oil. Refer to the
Auxiliary Shaft and Camshaft Bench Procedures
in the REPAIR INSTRUCTIONS section.
Refer to Figure 266.
Replace the auxiliary shaft as an assembly only.
Do not try to dismantle or rework the shaft since
doing so may result in damage to the engine.
1. Lubricate the front auxiliary shaft journal (2),
rear auxiliary shaft journal (4) and shaft
bearings (in cylinder block) with clean
engine oil.
