Hub nut torque for trailer

[chriz1]

I have one of them small galvanised trailers Noval Portaflot bit like erde does anyone know the torque for the hub nuts?

Hub nuts are normally FT.

Get it as tight as you can with a sensible length lever and you should be ok.

You need to establish whether the hubs on your trailer are ball bearing or taper roller bearings.

Ball bearing are frequently FT as trickywoo puts it but if you do that to taper rollers they will overheat & fail in very quick time.

I will have to open up the old ones and check

As above, taper bearings need a bit of set up more than just doing them tight. I learned the hard way years ago when I was young and dumb. I got up the road and my wheel plopped off after shearing the stub axle.

The basic explanation is to carefully tighten the nut while spinning the wheel up to the point that it stops spinning freely. Then wind it off a little and give the wheel a spin to make sure it's not dragging too much.

Doing it accurately is a bit more technical than that.

[paintman]

Simple way of doing taper rollers is to do up the nut whilst spinning the wheel in its normal direction of travel.

Then undo the nut a bit at a time, again spinning the wheel.
When I can JUST detect play when gripping the wheel at 12 & 6 o'clock lock up the nut in the appropriate manner for that hub - frequently a split pin but sometimes a tab washer & two nuts (Land Rover use that).

With the split pin & castellated nut - common on trailers - you may need to slacken off a tad further if you don't want to file the nut.

Never had a running issue & never had a problem with the MOT.

Thanks for that

file the nut.

Not as clever as thought I was, It's a new one to me and a cracker
