Title: Primary cases needed for Sunbeam Model 9 sports 1936
Post by: sports9 on July 12, 2015, 06:00:39 PM
HI everyone, so today the chain decided to come away from the clutch and bust a fairly substantial hole in the back primary case, not only this but it has cracked the outer case as well in a number of places. Obviously I can't use the bike until this is fixed and I have already covered something like 4000 miles on it this season alone. Does anyone have a spare set of primary cases that go with the burman clutch and gearbox. See photo attached...

Hello Sports 9 - Did you have any luck locating some cases and have you considered the repair option?

well I have found someone who is trying to weld the damaged cases up, but the break revealed far more extensive damage to the case which had at some point been welded. The only problem being the weld had finally failed because there had been no attempt to cut out the cracks. So in short I am still looking for a good set...if you know where there might be some please let me know.
