. . . vagueness.
Welcome, boutsy. This section really should be for introductions. You know—height, weight, location, number of failed relationships, whether you like puppies or kitties. Mechanical problems should go in the Workshop where everybody can have a collective laugh at them.
In the age of Tapatalk, jpegs and screen shots, vagueness is unnecessary. To which of the parts in the attached diagram are you referring—12, the pivot pin maybe? If none of those, go to the parts fiche at MAX BMW, find your model, find the diagram, take a photo, post it here and identify by number. I don't see final drive in your photo but I should be asleep now anyway—maybe I am and all this is just the result of too many french fried potatoes.
Removing seized parts takes patience. Applying heat with a heat gun, hair dryer or powerful exhalation with a mouthful of Carolina Reapers, followed by penetrant and a tapping of the part with a hammer then returning after a nap to wrench it will often work. Sometimes it takes several tries and several naps. Other times—after the nap—applying freeze spray to the stubborn part then wrenching it will do the trick. I've seen patience using this process with a properly fitting socket or hex key and a breaker bar or long-handled ratchet work where using an impact wrench has failed while also ruining the fastener. Success may be elusive but at least you'll be rested during the struggle.
How about posting a photo of your bike in the Klassic K-bike section and putting your bike's model and year in your profile so it will show up in every post you make here from now until the end of the world?
You're welcome.
