  • New rim, Old center and no fit.
  • The wife is on me to get the Demonstrator prepped for show and it is on the slow back burner. Some initial repairs followed by finally getting around to putting the 881D together and shortly after that the Demo will get started on in earnest.

    Meanwhile for the Demonstrator. . .
    I picked up a new "Made in India" 6 loop rim and naturally the rim bolts are different. I finally got that ironed out and will even deal with the valve stem on the inside rather the the OEM outside placement.
    The center binds where it is supposed to mount up over the welded on loops.

    Grind the rim? Center? Both?

    I found out that a 13.6 X 28 filled tire weighs in around 600 pounds. Add some pie weights and makes me wonder what the axle weight capacity is on the 871 Demonstrator?

    Next time I deal with a filled tire, I will be doing it differently.
    Handling a 600 pound fluid dynamics experiment can be fun. I don't need that much fun.

  • Re: New rim, Old center and no fit.
  • KUDOS on restoring your goldy. I’d be sure you have the correct rims and centers first. It would much easier to trim a center disc than grind away at a rim. Do the bolt patterns match up? But, before you do any doctoring, if your centers are OEM I’d return the rims –who’d you buy from, it matters? OEM 600-900 used 10 x 28 rims with 12 x 28 tires. Why would you use liquid ballast AND pie weights? Me? I’d use Beet Juice (Rim Guard) and discard the pies if going to use as a working machine. I suspect you are restoring for show adding pies are fine but you don’t need both, IMHO. Pie weights were supplied in two different classes - standard at 30 lbs each segment or the HD set at 45 lbs each segment. Your 600/800 OEM Owner’s Manual has a weight chart for liquid ballast AND pie the weights so you can do the math yourself. I have an OEM pair of Hat Rims, 28 x 9 and will hold (10 x 28) 11.2 or 12.4 tires both were spec'd for use on the Hundreds,–email me if interested.

  • Re: New rim, Old center and no fit.
  • Thank you for the reply. Goldy is on the slow burner. One of these days, months, I will need all kinds of paint questions answered from equipment to paint used.
    My attitude, which is not shared by the wife, is new rubber and beet juice.
    The pies are going to the 881D that will get the front loader also.
    Goldy will get a straight front blade. Not totally useless but pretty much...
    It will get used in the winters that is snows on the road outside the house primarily.
    Currently the plan is a force fit the wheel center and use it for now.
    I have learned that I will never again put pre-loaded tires on a tractor.
    I will install them empty and then fill or get them filled.
    600 pounds of liquid dynamics is entertaining and I am surprised my back is not screaming at me today.

  • Re: New rim, Old center and no fit.
  • To spend money for an item that does not fit, sucks. I have found that installing a wheel center before mounting works better. It is easier to get the wheel to "shape" to the center. A loaded tire added to any distortion makes it more difficult.
    For fluid loaded tires I bought a stainless steel pump that can remove fluid or install fluid. It is slow but cheaper than having a tire shop do it.
    Any pictures to share of your projects?

  • Re: New rim, Old center and no fit.
  • Thank you for the response. Where did you get your stainless pump? I was in the process of installation and just adopted the force it attitude. Hopefully it works for now and I will have to deal with it soon enough. Indian rim beats a
    "Chinese nearly". My problems could be worse. Bolts all line up and that is good, I finally did find the newer style carriage head bolts that will fit the rim.
    Those are coming and. . .
    Thinking about this I will need to find a blue plastic barrel to drain into, dismount, fix the wonderful thing and start again with grinding.
    Oh well. That will be later.
    Time to go pull rake off the front blade from a '77 D4. Good Cat. Electric start with no pony motor. She desires to play with it later.
    Yes dear, Happy Mothers day dear. . .

  • I just went to the barn and got the pump. I still have the original box. I forgot that I bought it at Harbor Freight.
    My e-mail is open. Send me a message and I'll forward some pictures.

  • Re: New rim, Old center and no fit.
  • Wow. It has been years ago that I bought that pump, maybe 20+. I would think though that a person could find one on Amazon.
