Engine Mechanical problem
2000 Audi S4 Question 6 cyl Four Wheel Drive Manual 75000 miles
I am in the process of replacing the timing belt and have the Audi factory manual. It instructs you to
Position the engine at TDC
Install locking pin 3242
Remove vibration damper on crankshaft
Remove idler wheel for toothed belt
I am ok up to hear but this part does not make sense
Compress the toothed belt tensioner and insert tool
T40011 and then remove the toothed belt
Insert camshaft clamp 3391 in securing plates of
Slacken both camshaft bolts and remove
approximately 5 turns
TAKE OUT camp 3391
Pull off both camshaft sprockets
Reinstall both camshaft sprockets and the securing
plate and tighten hand tight (so they can
rotate on the taper shaft but not move axially)
Install new toothed belt
Install camshaft clamp 3391
Remove special tool T40011 from tensioner
What is confusing me is that once release the tension on the belt and remove it what is preventing the cam shafts from rotating in relationship to each other and the crank!
I understand that the clamp 3391 will hold the cam sprockets in alignment but they are seated on a tapered shaft ie not keyed.
It seems to me that value springs could very easily move the cams and screw up the timing.
Am I missing something?
have the same problem?
