can anyone run through the process of adjusting the front wheelbearings on a kzn130 please, failed m.ot cos too much play in bearings, did say if play had been same in both wheels he would have passed it, which seems strange to me, but m.o.t,ers are a breed apart.

Having a 55mm socket makes this job really easy.
If bearings are in good condition and have been packed properly with grease you are good to go.
The first nut should be tightened to seat the bearing, 41lb.
Turn the hub back and forth a few times to seat bearing and then slacken off again.
Re torque to 16lb and then check for play in the hub.
If you have play then repeat step one.
Once you have no play check the hub preload (attach a spring scale buy hooking it over one of the studs on hub, preload should not exceed around 5lb) if preload is too great then slacken and slightly reduce torque setting.
Put flat tabbed washer back on.
Now put other nut on and tighten to 65lb.
check for play.
Fold one tab on tabbed washer backwards and one forwards.
If anyone wants to disagree with my settings feel free, I'm going on past experience and it's worked for me.

i paid £20 for our socket but it makes the job a doddle and you don't mark the nuts with hitting them with hammer and screwdiver.
Plus you simply can't use torque settings without it.Alan

Truth be known, I've never done the torque thing, I doubt many mechanics ever have. Tighten the nut up reasonably tight to set the bearings, slacken the nut off, then retighten until the play has gone. I reckon that's as good a way as any, certainly the only way I've ever done it in the 32 years I've been dabbling with spanners.Do you know that, with a 50 character limit, it's

No pics but it's a very easy job to do.
I have revised the settings.

If you have standard hubs take care taking off the hub face plate, it is retained by 6 nuts and cone washers, these might stick a wee bit so loosen the nut but don't take them off until you have gently tapped around the face plate to unseat the cone washer, that way they won't fly across the workshop.
Clean all old grease and replace with good quality bearing grease.
Properly work in new grease to taper bearings.Alan
