20.19Checking the timing assembly
200478-01
– Clean all parts well.
– Check idler  for damage and wear.
» If there is damage or wear:
– Change the idler.
– Check timing chain tensioning rail  for damage and wear.
» If there is damage or wear:
– Change the timing chain tensioning rail.
– Check timing chain guide rail  for damage and wear.
» If there is damage or wear:
– Change the timing chain guide rail.
– Check camshaft  for damage and wear.
» If there is damage or wear:
– Change the camshaft.
– If the cam surface is damaged, check the oil supply to the camshaft and
cam lever.
– Measure the cam height.
Guideline
Camshaft - cam height
Intake 39.34… 39.44 mm (1.5488…
1.5528 in)
Exhaust 38.59… 38.69 mm (1.5193…
1.5232 in)
» If cam wear is outside of the tolerance range:
– Change the camshaft.
– Check timing chain  for damage and wear.
» If there is damage or wear:
– Change the timing chain.
– Check that the timing chain links move easily. Let the timing chain hang down
freely.
» If the chain links no longer straighten out:
– Change the timing chain.
– Check guide rail  for damage and wear.
» If there is damage or wear:
– Change the guide rail.
20.20Preparing the timing chain tensioner for installation
200171-10
– Fully compress the timing chain tensioner.
Info
This requires considerable force since the oil has to be pressed out.
Without pressure, the timing chain tensioner expands fully.
200172-10
– Place two spacing washers or similar aids next to the piston of the timing chain
tensioner. This should ensure that when pushed down, the piston does not fully
withdraw.
Guideline
Thickness of spacers 2… 2.5 mm (0.08… 0.098 in)
