One shot nuts,

Rogue Wave · 14 February 2010, 17:56

1'm under the impression that all sealed bearng hubs are held on with one shot nuts am i right or wrong

Dirk Diggler · 14 February 2010, 17:58

According to ALKO, yes, although I've re-used them without problems.

Downhilldai · 14 February 2010, 18:01

Me too.

GED · 14 February 2010, 20:45

me too used lock tight as well

Is it really worth the risk for sake of a nut? If you are replacing the sealed bearings any good supplier will supply them with the nut.

All well and good, but then the "free" one shot nuts would be wasted

just replaced my one shot nuts with new ones after i put new brake shoes on my twin axle trailer. 4 nuts £14

they are called one shot for a reason why debate for the sake of 14 nicker??

To quote the man that serviced my old ALKO based trailer.
"The nuts are made out of round, you need to put them on at about 250 ft lbs. Once used and removed they are no longer out of round, therefore IF you re-use them and torque them up to the recommended level you will harm the bearing"

Don't shoot the messenger but for the sake of £14...... Never mess with the bearings.

He may mean a stover type nut, not sure how this would harm the bearing and at 250 ft/lbs it wont be coming off (you'd hope...) We have re-used them in the past with no damage to bearings on avonride hubs.

My big hammer or vice would soon make them out of round again.

by the time you've wound them down the stub axle they're round again anyway, wind it on tight and use a hammer and centre punch to put a dent right on the edge of the nut that will distort it enough not to unwind, total bollox about harming the bearing, the bearing is or was the same as a vauxhall cavalier rear wheel

250lbft is pretty tight, but i cant see it distorting the inner race if its overtightened, unless the bearings are made of chocolate

stub axle would stretch first. its just their way of making sure total muppets dont reuse knackered nuts with no locking device.

the inner bearing sleeve is the only thing that is taking the compression as the bearing ain't tapered there's nothing to over tighten, you're more likely to strip the thread on the stub, you could always put a bit of nut lock on it
