Duck asked me to post this awhile ago, so here goes:
Busted Hard Case Hinges? No problem, go to this fiche on Bike Bandit - http://www.bikebandit.com/1992-bmw-k75/o/m82#sch352509 (http://www.bikebandit.com/1992-bmw-k75/o/m82#sch352509)
or simply order this part#: 376260
Pry the old busted ones off the small plastic studs that hold them on the case like this,
Then push them off the rest of the way with a drift or big nail and hammer like this.
Slide the new ones on...
Until they click into place.
Done Deal.

Thanks for posting this.
Th BMW part # for the hinges is 46542300039. There are two per side.
FYI: I find that a 1" chisel is a good tool for sliding them off with some light taps from a hammer.

This thread caught my eye. The previous owner of my bags cobbled one back together with a couple hardware store hinges. Little did he (or me) know they are a $5 piece from the Bandit!
BTW, the part number is 376154 if I'm reading the fiche properly.
-
They're $5.50 each at http://www.bobsbmw.com, now $6 each at Bike Bandit.
Just sayin'

My first set of hinges failed while on a trip. Since then I carry 2 spare hinges with me all the time.
-
Replaced mine with hardware store hinges 20 years ago. Don't need to carry spares. Face it, some BMW OEM parts are failures waiting to happen.
-
What hinges did you use and how did you attach them?
-
I carry a couple spare hinges in one of the pockets in my case liners. I had to replace one when I dropped my K75RT on a muddy Nebraska road a couple years ago. Took about 10 minutes on the side of the road to change it. I like to think that the hinge breaking saved the case when the bike landed on it.
Considering that these $6 hinges probably have nearly 25 or more years on them, and a couple thousand cycles, I can't really complain when one of them fails.

I think I used 1 1/2" or 2", just drilled holes and bolted them on. Pop rivets would work too. Same deal with the pot metal latches.

Thank You.... Well done and with pictures... Awesome :riding:

That must also explain the sacrificial mirrors and turn signal lenses BMW is so fond of :clap:

I've replaced one complete set in twenty years. And mine have always given me warning of the impending disaster by one hinge always starting to split first. I only had to replace one side late last year. And I should carry spares, and I will get around to it eventually. :dunno
Regards Martin.

Hmm... $4 for a pair of hardware store hinges that will last ages, or $6 a pop for something that'll go south in a year or two of regular use. Guess I'll be heading to Ace soon. I like the pop rivet option.
-
I bought my 91 K100LT new in 91 and I have only replaced one set of hinges. I do carry a spare set in the bags but I have never needed them. I wouldn't consider them to be a once every year or two by any means.
-
Glad I found this thread. The outer shell on my left case fell off when I opened it on Monday. Thought I’d have to replace the whole thing but no. They’re up to about $8 per hinge now.
-
A couple of people have 3D printed tragkorb hinges. One was an OEM copy and one was a modular multi part hinge with a bolt as a pivot. However as per a lot of Brick owners I'll stick with the OEM as they lasted well over 20 years the first set and I now carry a spare pair.
Regards Martin.

I bought a set of replacements when I first got my '91 R100RT because I was unimpressed with what I thought were flimsy hinges that would fail at any time. 40k miles later those are still working fine.
A slide into a ditch with my '93 K75 caused the case cover to detach because of the sacrificial hinges saving the case as a whole. I did have to replace the lock at the bottom but new hinges and lock brought it back to regular use.
