Hello everyone!

Are you not confusing this with a timing belt slippage issue on (presumably) 1Z/AFN (or something similar), where the cause was a worn-out ESP mounting?

Best regards from Munich!

Hi,

No, I mean, we had something like that in a quiz before...

Hi,
Okay, hier ist die Übersetzung:

'This is about a Golf AFN.' He used the same 'standard' spring mechanism as he did with the 1Z.
The A4 AFN and Passat AFN also have a spacer element.
Later engines were the ones that incorporated the spring/damper combination.
The part in the third picture is also a spring element; you can even see the ends of the coil spring.

You're right that the strut is just a simple component with a coil spring, but over the years, that part can also become worn out.
As I mentioned, the belt on my Golf started 'fluttering.' Even the new one was fluttering.
It got slightly better when I used a shorter belt, and eventually stopped completely when I replaced the tensioner.

Now that you mention it, I'm starting to understand.
I think that was a bent tensioner arm from a 2.5-liter engine, and it was posted by someone from the GTI forum?
ABär, that was about the belt wear pattern, not the belt shedding (I'm saying this very cautiously! ).

Best regards from Munich!

Why industrial engines? That's the normal KRR (Knock Return Rate) behavior of a G3 TDI engine without air conditioning. The servo on my MJ 96 1Z was connected using a separate V-belt. m;

Yes, that's the normal way. I had an engine with air conditioning and power steering, but I had to modify it.
VW also provided an instruction manual for industrial engines, which included details on all belt-drive variants, along with parts lists. That's all, I'm sure there were other ways to achieve the same result.

In that case, you would have the timing belt system from a Golf 3 1.9 TDI without air conditioning.
The servo in those models uses a small V-belt, regardless.
You can also remove the KW pulley for the power steering, but it's not necessary.

Sure.

Okay, it's the weekend now, maybe I can report back on Monday.
Goodbye.

Is it crowded on the bus?
I have only seen 2.9 VR6 and 2.3 5-cylinder engines in vans in person so far.

Hi,

It depends on what changes you want to make. With the double pulley, the exhaust would have to be removed in order to install the belt.
Besides, I didn't need it anyway.

Regarding the actual topic, I'm afraid I'm no smarter than I was before.
On Saturday, I installed the new belt and the engine started up and is running.
Tested it again on Sunday with a cold engine, and it works.
Everything is smooth and easy to operate, nothing is loose or bent, and the freewheel mechanism also works.

I suppose I'll have to keep observing.
Thank you everyone for the tips.
