Thread: Rebuilt front swivels running in required?

The hub nuts were definitely under tightened, probably me being too timid (and relying on the dial gauge), rather than my senses… I snugged them up, which took all the play out. I’ll check again in a couple of weeks to check no play has reappeared!

Thanks for everyones advice and help, much appreciated.

After adjusting the nuts, on the next run for any distance, stop after about ten kilometres, preferably without using the brakes, and check the hub temperature by hand. They should all be the same. If one you have just adjusted is hot, suspect overtightened nuts, but make sure it is not a dragging brake by touching the outer edge of the drum (carefully!).

I've found that I have less issues now I press the bearings in on a 20Tonne press.
Using a drift to insert the outer races you're never quite sure that the race is fully pressed home so it moves a touch the first time it's subjected to cornering loads and suddenly the bearings are loose.

I used to set up with a dial gauge but now adjust with a just perceptible end float. As Chris mentioned, you can only confirm the endfloat or lack thereof by tightening the locknut. This takes up any play between nuts & thread on the stub axle.

On my Series I three wheels have the original Skefco bearings which are greased, one had suffered water ingress before I purchased it so in went some no-name bearings.
The no-name bearings seem OK in general and the cost of big name bearings for Series I to III is prohibitive. One of the races is an odd size, last time I checked an SKF set was over $300.

I've found it easier to detect and adjust the end float with the wheel on the hub. However, it's also easier to over tighten the hub nuts. Therefore when using this method it is important to remove the wheel when you've finished, to make sure there is no resistance when rotating the hub.
