Anyone know what these are for on a Type 4?

I recently discovered these little plastic parts in a pile of NOS VW goodies, and asked around locally as to what VWs they fit and what the applications for these plastic parts were for. They are about 15mm long, the inner diameter of the hole is approximately 6-7mm, and the outer diameter at the widest part of the "fins" is about 12mm. One very knowledgeable mechanic friend believed that they were parts on Type 4's, although he couldn't nail down what they were.

So I thought I'd post photos of them here, and maybe one of you knowledgeable Type 4 fans might recognize them and let me (and all of us) know what these are, what they fit and do, and how many were used on a T4.

Anyone? Anyone?

They are listed as harmonic dampers. They go around the 10mm through bolts that clamp the case together. They stop these long bolts from vibrating and wearing the case or loosening the nuts.

Part # 28 in the diagram above.

Wow! Fantastic, and speedy reply Ray. Thanks again for solving my mystery. I don't have a Type 4 motor anymore (I had one long ago in a '79 Westy), so I imagined that they were some sort of seat or upholstery part. According to your info, six are needed per Type 4 motor, and I have exactly six of them in this parts pile. I guess I'll post 'em in a classified ad so they can do someone else some good, as I don't imagine that I'll be owning a T4 motor anytime soon.

Again, thanks for sharing the info, and shedding light on my mystery parts...
