What could they have been thinking?

Who in their right mind would fill the gearbox on a snowblower with white lithium grease in the Frozen tundra we call the Northeast.???
  
We are working on a current repair in the shop. It is a Noma/Murray snowblower....look at the picture at the right and tell me what you see......

Simple, first of all......not enough grease, and it is a sealed box so it would never have leaked out.Second, the grease gets pushed almost immediately out to the edges...and what do you think happens? yes,....you are right  the white, cold, grease that has pushed out to the edges doesn't contact that  brass gear you see in the forefront that works in conjunction with the worm gear and all this pretty gold glitter is created and causes the eventual demise of these two gears.



For a few pennies of a bit more grease, or maybe the use of a liquid grease or some sort of gear oil we could have avoided buying these.......
at a cost of about $ 200.00 for the brass and worm gear, plus many hours of labor to rip it apart, clean and preparation and reinstall.....and I know once we install with the proper amount of lubrication they will probably last the life of this snowblower, because, believe this or not the are MADE IN THE U.S.A.!
