Good morning gentlemen,

I'm planning a rebuild of my gearbox as a part of a dog came out with the oil..viewtopic.php?f=1&t=4667
Is there any best known practis, what to look for and what should be done? Never open one of these before..

Thanks and best regards

Check the links at the bottom of Anton's page, especially Joerg's. Lots of good info there.

Cheers, Jorg''s page looks really good!

hal, the main reason to do the job yourself is that you wish to have a project. By my 10th transmission I was getting fairly comfortable with them. That was too bad, as issues kept coming up over the years that caused me great pause.

If you just want a working transmission, then send it off to one of the experts who has done many of them. In your case, it is going to be expensive to buy and replace those broken parts.

Better to buy a spare that is in working condition and then use it while you go through the learning curve of doing it yourself.

Anyone that expects to ride one of these bikes for years better have a spare transmission just sitting and waiting to go into service. Your down time will be in hours, not months.

Thanks Duane, I actually have an old one in pieces in a box. Trouble is, being in Norway, I can't find anyone rebuilding them. Nearest one is motobins in England end they don't do exchange out of country anymore. Guess shipping to and from the US would kill me.. Maybe try Germany?
Asked the most decent BMW shop in my wide area and they ask more than 3500US$ for a box.....

E-Bay. About 1 a month.

eBay Germany.

How many do you want?

Motorworks in England would sell me a reconditioned box without exchange for around $US 800-, and post it to Australia for another $100- excluding VAT

Not cheap if your box is in reasonable condition and you have the special tools necessary to rebuild it, but if you require any replacement gears or shafts, and have to buy the tools, it will be cheaper.

Some of the replacement parts are already going NLA, so having a spare box around is probably a good move anyway, as has been previously suggested.

Al right, I'm listenig to you guys and at the same time are a bit anxious about buying a box from ebay not knowing the state of it. The one I have hasn't really shown any real evidence of being faulty other than a habit of passing second on downshits and hitting a extra neutral. And then a bit of the dog in the oil. But having had the prior tranny locking up for me I don't want that experience again..

They won't ship outside the U.K. The page I found says they want a replacement box, too. They sure have good prices though.
