C12 front wheel alignment
« on: November 24, 2008, 04:50:00 pm »
When I bought my C12 it did not have the correct front mudguard, so I discarded it. I then realised that the front wheel was not centered in the fork. I looked at the wheel spindle which was correctly fitted. I took off the wheel and found that the bearing locking rings had been installed the wrong way : right one on the left and left one on right. So the brake plate could not fit inside the right ring and the wheel was not centered. I think this is a common mistake when rebuilding a wheel. One should note what goes where when removing parts for a rebuild.
I also noticed there was rubber washers between the bearings and their locking rings. I think that on my bike these have been home made and I am not sure they have the right thickness. These washers are used to prevent grease to escape. I shall fit sealed bearings but retain the washers so the thickness is important to have the rings well tightened. Can anyone give me the dimensions of these washers ? Thanks.

The grease retaining washers were original made from felt; referred to I think as 'engineering felt'. There is a large and a small one.When I rebuilt my wheels, Dragonfly had one but not the other. I used sealed bearings and fit one new seal and one old one (which wasn't too bad anyway). Have you tried Dragonfly, C & D or Autocycle? If not, give them a ring. Joe

Continued...... The grease retaining seals are not strictly necessary for the point of view of tightness. The felt seals fit inside the recess in the lock rings. It is the outer periphery bit of the ring which bears onto the wheel bearings. Sorry, I have given you some duff information, it is the rear wheels which have the felt seals, rubber in the front. I was unable to obtain new ones so put the old ones back and used sealed bearings. Still going well after 3 years of light use, Joe.

thank you Joe. I shall have a look at the online catalogue from Draganfly
