Bearing Pre-load

[kayamtom]

Hello

I am repacking the bearings on my 1962 Overlander and am wondering what torque load (if any) to apply to the locking nut?

The trailer has the 12x2 brakes if that is important.

Many Many Thanks

They don't need any preload. The correct method is to tighten the center nut and give the wheel a spin. This squishes the grease out of the bearing. Then back off and tighten it again, barely snug, and back off just enough to get the cotter pin in.

Did you replace the grease seals?

If not, your taking a huge gamble.

If you did, great PM.

I think you should torque the nut to 40-50 ft-lbs to seat the races, then back it off completely. Retighten finger tight, back off to the nearest hole and insert the cotter pin.

Unless you replaced a bearing the races should be seated by now.

While spinning the drum I use a pair of channel lock pliers and tighten down on the castle nut. Not too hard just good and snug. Back off about a half turn and then again tighten while spinning. Note the position of the castle nut slots with respect to the cotter pin hole and back the nut off to the next hole. You should be able to feel some free end play in the drum when done.

Better a bit loose than a bit tight.

Hello again,

Super Speedy and informative responses. I like it. Thanks for your time.

I have new bearings races and seals so there is a whole lotta lurve going back into trailer. I even have some blue grease!

So the thing to do is wind the nuts up to the 40/50 lbs for the races and then wind he drum back and forth and ease off the nut to find that little bit o play?

Thanks again and kind regards

If you are setting new bearings make sure you have cleaned the areas of the hub that the bears seat in. Cleaning the stop face is most important as any debris may cause the race to be tilted in the hub.
