Wheels and Bearings

[lawson17]

Does anyone know if the spacer between the bearings needs to be tight up against them?

I have replaced the bearings and seals in both wheels, the front spacer is a snug fit between the bearings.

The rear has no sideways movement, but quite alot of up-down, forward-back movement.

Is this normal?

Thanks Lawson17

This doesn't sound too good, are you saying that your rear wheel is moving indepently of the suspension?

I take it the axel is done up properly.

no, somthing is not right

Thanks Lawson17
yes,as long there is no sideways movement.
once you torqued axle spacer is tight against bearings.

YES ITS THE NORM!!

Ive never done a bike where it doesnt have up down movement

[hovis]

are we on about the wheel?

What he said. The spacer between the bearings will pretty much always move around a touch. How do you think us spannering types get in there to drift the old ones out from the other side of the wheel?

Morning all.

As Lozzo states there should be a little sideways movement of the spacer when installed correctly.
On some wheels one bearing goes against a shoulder in the wheel, & the other doesn't. On such wheels you install the bearing that goes against the shoulder first. Then, with the spacer in place, carefully drift the other bearing in until it just touches the spacer, finally push the spindle through to align the spacer.

It can be tricky to get right, but the ideal situation is when you can move the spacer sideways to a degree, but there is slight friction against the bearings.

On wheels where both bearings go against shoulders in the wheel, one usually finds that when both bearings are fully home there is adequate sideways movement of the spacer. Still go carefully though when installing the second bearing.

When fitting new bearings, it pays to warm the wheel gently with a hot air gun, or a blowtorch if you're careful, & to lightly oil the outside of the bearing, & the recess in the wheel.

The best tool for drifting the new bearings in is, wait for it!!.....The old bearing! With it's circumference ground down a little so it doesn't stick in the wheel, & the inner of it ground back a touch so it doesn't touch the inner of the new bearings. Only ever tap on the outer race of the bearing, & tap gently around the circumference to keep everything square which prevents the new bearing jamming in the wheel.

Cheers.

on rear wheel right bearing goes first against shoulder.on front wheel left bearing goes first against shoulder.
if both bearings go against shoulder spacer is short.both bearings should never touch shoulder,only one.
