Front wheel spindle locking solid

(1/4) > >>

Laverda Dave:
Hi all,

I think I might have a problem with the front wheel spindle of the 400 project bike and I'm looking for some guidance.

I have installed new wheel bearings supplied by DS into both sides of the wheel.  The spacer has been been refitted as per instructions however...... when I install the wheel spindle and torque it up to the setting as described within the Haynes manual of between 36-39lbs the  spindle goes solid, i.e the wheel will not turn on the spindle. Finger tight all is fine but anything more and it gets harder and harder to spin the wheel.
All the correct spacers have been installed, the new bearings are 'home' and the wheel spindle is greased and everything moves freely. I did notice the bearings supplied from DS are sealed on both sides of the actual bearing where as the ones that came out have the balls exposed on one side although I do not know if these were genuine (and they were worn anyway).  I also noticed the spacer between the bearings have three 'tangs' on each end of the spacer, are these supposed to locate inside the exposed side of the wheel bearings, although obviously they wont locate in the DS supplied bearing as they are sealed!
It appears as though the wheel spindle nut is pushing hard on the adjacent spacer that goes through the dust seal and this is pushing onto the inner bearing race and compressing everything solid?
Am I doing something wrong, is the spindle nut supposed to be torqued as per the Haynes manual or is this one of the Haynes errors?

Dave,
I replaced mine not long ago with a set from All Balls and had no problems.
Sadly I don't seem to have kept the instruction sheet though.
Just a thought - are you putting the axle nut on the right way around?
The hex part goes towards the hub, and as I recall I couldn't torque mine up as I would have needed a very deep socket to reach over the nut to the hex.
Oh, and I think pretty much all bearings are sealed on both sides nowadays. They are sealed for life so you don't have to pack them with grease.

Trigger:
Make sure the tags on the collar are not bent and are not in contact with the bearings. Never torqued one up before, just tight.

I had this recently.  It all looked fine but would lock up once tight.  I discovered that the bearings just weren't in place far enough.  Another really good few taps with a hammer had them home then it ran fine once tightened.  I used an old wheel spindle passed through the bearings as a drift then gave it a really good whack.

What Florence? If you drove it in with blows to the inner race failiure in the very near future is almost a certainty!
