My Chain Tension Plate... BMW part number
33177650081... which BMW calls a "Supporting Plate" in the
parts fiche... went belly-up on my
last trip. As you can see from the pictures below, the innards
pulled out.
The field repair was to simply take the
broken-off piece and use it as a washer on the outside of the plate.
It looked like hell, but it worked.
A new plate from BMW is about $11 online.
$11 for what though? A poorly designed POS aluminum plate that breaks?
I don't think so...
I got to looking at the TT version... Chain
Tension Plates F650GS, Part Number: 051-1206... about $30 for two
plates. These are made from steel and have a nice finish on them.
There are also holes on the tabs so you can screw the chain tensioner
to the swing arm; you'd have to drill the holes in the swing arm and
find the appropriately sized bolts though... I chose not to do this
yet.
Here are some pictures of the failed BMW one
and the TT one...
It comes with two bolts to replace
the stock bolts, but I like the Torx bolts, so I kept them.
Looks like this installed...
The
only minor complaint I could come up with is where the tabs mount to
the plate. You can see it in the imperfection in the first and last
pictures, but it's really nothing.
