I have an early 1990 870. The two nuts came off the spindle in the hub and the wheel/tire/axle fell off. I have repaired the threads and installed new seals and am wondering how to go about tightening the double lock nut assembly.

Front hub

No, mine is a 4wd so the front hub is kinda like a big box with gears in it. I'll try to find a picture.

That looks like spanner nuts. Do you have a spanner wrench similar to this?

Spanner wrench

If you don't, you can use a punch and a hammer to tighten but this usually marrs the nut's squared edges. Works in a pinch though. Sears might carry a spanner wrench, their site was down so I couldn't check it?

Was this what you were looking for?

:gtt:

That's part of what I am looking for. The other part is how much do I tighten the first nut. Do I tighten as much as possible and then back off a little? Like on a car wheel?

I'm going off of the picture only here, I'm not familiar with that particular axle or the tech manual specs. Hopefully one of our technicians will be along shortly to correct me if I'm wrong.:nunu:

The bearings appear to be regular ball type bearings and not taper style. If that is the case and only the inside race is being compressed by torquing the nuts, then tighten appropriately and do not loosen back up. If the bearings are tapered roller style then you will need the actual torquing procedure. I'd be willing to bet that the procedure would be similar to what you stated in that case, but the exact specs would be what you need. :read

Sorry I wasn't of more help:dunno:

They are ball bearings. So it looks like I tighten the first nut down good and tight and then just set the lock nut.
Thank you for your help.

Similar Problem with the 870 front hub

I have already gotten the spindle nuts off with little issue. I to have dismantled my front end do to the leaky seal in the 4wd photo that Paulpat submitted. #4 in the drawing. My big hurdle that i have gotten to is #7, the bearing. I need to get it out of the way to get to #6, the snap ring. But there is no way to grab the bearing or drive it from the outside. There has to be a way to get this stupid thing out:banghead: I have turned it upside down and tapped the housing, then i hit the housing, THEN I BANGED ON THE HOUSING. But that stubborn thing won't come out and i am at my witts end trying to remove a bearing that seems like it is being held in by nothing. Help.....HELP!
