Hi everybody! I'm new to the forum, I have been reading a lot since i bought my V11 Ballabio this summer. Found lots of very handy info for my new bike. It's winter time here in the Netherlands so im doing some maintenance on the bike. Previous owners did not really give it a lot of ''love'' to say the least. Not all is bad! went over the major things and found nothing shocking so far. Today I took off the rear wheel in order to clean, inspect and lube components such as bearings, U-joint the lot. I found this needle bearing located on the RH side of the rear drive housing. The axle was lubricated however the needle bearing looks shot. Its filled with red corrosion and needs replacement. Below some pictures of this needle bearing: no. 30 = bearing inner race no. 31. = needle bearing I cant really understand why there is no seal to protect this bearing? There is a steel washer mounted between the bearing and the inner surface of the swingarm, i cant imagine this protects the bearing against water and other debris..... Secondly I cant really see the point of this bearing (please feel free to teach me). The axle is not rotating, so why is this bearing here?
I have just pulled the front forks on my 04 Ballabio and on checking the front wheel bearings found one was sticky and the other distinctly lumpy so they need to be replaced. Marked up as NSK 6205 DU. Is there an approved method or tool for removing them or do I simply beat them out? (The BFI METHOD). I presume the bearing is readily available, but would also appreciate sources or alternative numbers. Before I go to knock out the inner race etc, how do you get these things ou as the lip in the wheel is tiny?
