Thixotropic Grease- A great solution in SOME instances

Posted on Wednesday, November 10th, 2010

What is Thixotropic grease?  A thixotropic grease is one that is a gel when at rest, but any motion or agitation immediately liquefies it.  With the lubrication technology available today, we can not only provide far superior oils and greases for our vintage vehicles, but with the products available today we can provide specialty products to address specific needs.  Look again at what thixotropic grease does…..  at rest it is the consistency of a soft pudding or yogurt.  Have a troublesome seal that either is a huge pain to address or just not available? Would “pudding” leak out?  Probably not.  What a great solution for those “weepy” steering boxes or leaky  differential seals.  The great part is that it turns to a gear oil consistency soon as you put your gears in motion. Originally known as “corn head grease” this product has expanded outside the ag market and  is now the standard gearbox oil for Rhino rotary mowers, Brown Tree Cutter HD Mowers and Snapper transmissions.

Usually rated as a NLGI “0” grade grease, this grease offers

  • Excellent extreme pressure and wear properties
  • Excellent corrosion and oxidation resistance
  • Outstanding high temperature properties
  • Available in 5 gallon buckets or standard grease cartridges

This grease will not magically repair a seal.  For normal parade duty it can be the best thing since sliced bread, but if I were planning on doing the Alcan Highway convoy, I would take the time to fix the transmission seal. This can also buy you time until winter when you can do major repairs.

As more HMV owners have asked about this and have tried to get it, they have found it can be difficult to locate, especially in suburban areas.  Because of this, VOV is now stocking this grease from Royal Manufacturing in both cartridges ($3.50) and 5 gallon buckets ($108).  Cartridges are great for steering boxes, but if you want to do your differential and transfer case, the bucket will be easier and cheaper.  The grease will pump through a good gear oil bucket pump or manual bucket grease pumps are available used or new on Amazon for about $115.
