Timing belt marks misaligment
« on: April 16, 2020, 10:14:18 am »
Hello everyone.
 I have found this forum looking for information about changing the timing belt on my mk5. I have not a lot of experience and I am in trouble. When I line up the marks on the crankshaft pulley, the marks on the camshaft are a little bit off, say a couple of millimeters. The arrow in the engine is still pointing the right tooth but not the exact point. Is this normal? I have rotate the engine several times and it is always the same. I have made my own marks and they align perfectly when turning the engine by hand.
I hope someone could tell me something abut this issue.

Hi,

Bottom end:
You should have a timing mark on the crank pulley not the main toothed pulley but the actually pulley for the aux belt. The pulley should have the dot/dowel lined up and the 5 or 6 bolts holding it on, on the back side of that pulley there should be a notch which lines up on the lower cambelt cover arrow. The notch is quite hard to see, but it’s there!

Top end:
You will have a tooth on the cam pulley with a notch on and this should match the back plastic cover with the arrow. I think the notch on the tooth is more aimed at making sure that the exact tooth is lined up to the arrow not the notch, so If that arrow is 1 or 2mm off from the notch but lined up on that tooth then really don’t worry.

As long as the lower notch matches and the top tooth matches you’ll be more than fine. If you’re unsure exactly what I’m talking about let me know and I’ll post some pics from when I done my mates last month.

Hope this puts your mind at ease.

Cheers,
Muff.
