Check strap repair solution

Totally ridiculous (but relevant) comment coming from a total non-engineering skilled but highly appreciative type......I bloody love engineering :)

What a great thread to follow.

I had assumed that the vast majority of the failures of these door-straps was caused by those weak rivets snapping? Well, that was certainly the case with my A2, and my Partner's, too. So is that not the source of the "clacking" noise , then? I can't see how things would change when a brass roller is used in place of the plastic type?. The action should be the same, regardless of the material of the roller that is used? O.K., there is a difference in durability, but most of the failed door-straps have had quite an amount of wear? I'm obviously interested in all this, though, and if brass rollers are the way forward, then they would certainly be fitted to my A2 ( I have a model-making friend with full engineering facilities, so all I would need are the dimensions)

yes wear and plastic wearing far quicker than a brass one would.

I thought I saw a visual comparison between the old and new plastic rollers on here and it looked like some kind of groove/cut formed which prevents the roller from functioning smoothly. Here is an example of the worn roller (post #20):http://www.a2oc.net/forum/showthread.php?13059-Drivers-door-checkstrap/page2

There's only one way to verify, and that's to replace the rollers with brass versions. I'll obviously report back once it has been completed.

That was quite interesting, seeing actual wear to the roller. Right, that's another job for my A2. I'm finally starting the back-illuminated rear number-plate project! I could have done with a spare plastic rear-hatch section (the piece that the rear number plate is attached too) Has anyone got this item for sale?

I've got one on the car David. If I can remove it without damaging the lower clips then you can have it.

What are the tolerances for the given dimensions?
I am planning to make some for myself. I dont quite know the shaft/bore tolerances.
I presume the Hight & OD have greater tolerance then the shaft/bore.
If anyone knows for sure, then i would like to hear.

Drop me a PM if you would like a fully refurbished door check strap
I’ve done lots of these and they are lasting a lot longer than the ones that Audi made

From my personal experience, I cannot rate @depronman highly enough for the quality of his refurbished straps. I fitted one on the front pax side and I would recommend anyone to fit those when the original ones are nearing the end of their lives.
