  90 Degree Gearbox Oil?

  Posted by DON on September 30, 2015 at 7:24 pm

  Would like to change the oil in the Superior Gearbox. P/N 411ACF

  Can anybody tell me what oil to use and how much?

  The correct oil is SHC 634, a product of Exxon Mobil. It’s hard to find a gallon, but I did at Alliance Chemical in Texas 512-365-6838.

  There are several web sellers, but they are all 5 gallons and over 200 dollars.

  I removed the breather on top of the box and pumped the oil out and measured to put the same quantity in.

  Amazon sells it for $20/qt.
  
  Do you remember how much it took?
  
  I see a drain plug and a fill plug on the gearbox.

  If you buy quarts, you will need two, and possibly not use all off the second one. Yes, there is a drain plug. I chose to pump out of the top by removing the breather for convenience of access, and I thought I would make less of a mess.

  Thanks
  
  I went on Superiors website, downloaded their bevel gearbox manual, and found they recommend a synthetic gear lube like Mobilube SHC 75w-90.

  It took 30oz.
  
  I cleaned out the spring loaded vent with carb cleaner while I had it off.
