Wheel bearings Sovereign

Recommended Posts

kwt

So last night I was blowing snow down by my shed and felt myself run over something big. I looked back and saw that it was a front tire and rim. Yikes. This is my 2000 Sovereign with the Honda repower that I bought last fall. It has front wheel weights so checking  the bearings is a little tougher. That's my excuse, I'm sticking to it.

 

This morning I check things out and find that the bearings weren't dry, but could have been serviced. I'm pretty sure than the locking collar just slipped off and out jumped the wheel. Both races are rough and the inner bearing is in pieces. I've read about using deck bearings in stead of wheel bearings and might do that. I really want this tractor to be running and not outside 150' from the house so I'll probably get whatever bearings I can get the soonest. I hate the thought of taking parts off the one tractor that's not operational (3112v), but I might just pull a wheel off of it to get me back in business.

Do you gentlemen, and ladies if present, know if the 1969 3112v wheels and bearings are the same?

The 3112V bearings will be the same.  As far as deck bearings, that will not work unless you have new wheels that would have a race that would work with those.  Deck bearings are flat standard type bearings,  the wheel bearings on these are tapered as are the races.  The bearings are still available, and many of us have spares (me for one) and could help you out.  For now, pirate off of the 3112.  If the races are rough, you can even swap out the wheels.

I'm definitely swapping the whole unit. Wheel, tire, races, bearings.

 

Deck bearings are pretty much whole units. The race is pretty much part of the bearing assembly. If using deck bearings, I'm sure I would have to remove the races from the wheels.

If I remember correctly, you can use somewhat standard trailer bearings, such as Timken “Set2”.  They were easy to find and included both the bearing and race.  

The mower deck bearings aren’t tapered.

All you have to do to use deck bearings is remove the old race from the wheel. @RayS has done this with success in the past. I still use the Timken cones myself. Sometimes I can get by with cleaning and repacking them if I'm in a pinch. New cones and races are cheap so long as you don't need the cone with the seal built into it. If so they are around 40-50 each through Simplicity but I have found them through NH or AGCO a bit cheaper. These bearings with integrated seals have a double lip seal and don't seem to have the moisture problems that I have seen with the newer style Simplicity seal/washer combination used on RBT's. Some FDT rims will not allow the race to seat deep enough to allow the newer style seal to contact the rim.

You can remove the old race an install deck bearings in the front wheel. Have a tractor that I done this to 10 years ago and another 5 or 6 years ago. Works great. No greasing and no mess.

Good to know. But, how do ball bearings handle side load (horizontal) stress?

The Z9504 deck bearings have a thrust rating of 60 lbs. This is the dynamic rating for a continuous load. For your application this is not an issue. In other words.....it will work just fine.

That's good to know Ray. In addition to needing new bearings and races, the seal is garbage, so I would have to get one or two of them.

Quoting directly from one of my mechanical engineering books, "Tapered roller bearings are designed to take substantial thrust loads along with high radial loads, resulting in excellent rating on both. They are often used in wheel bearings for vehicles and mobile equipment having inherently high thrust loads." The mechanical engineers at Simplicity chose tapered roller bearings for a reason, and the so called engineers at MTD chose otherwise.

True but the thrust load on a Simplicity front wheel is almost nil. If there was a high thrust load the spindle would have had a threaded castle nut and not a locking collar held with one tiny setscrew.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul

      folowing  this from a link at the downloads.  I just rescued an AC 920 with the lambodini diesel. I can' t download  yet .  Where did you find the PDF copy you posted. . I would like to figure out how to adjust the injection pump. 
      I assume it's a bosche, correct
