[AT] Wheel bearings

[Cecil Bearden]

My oil supplier supplies fuel oil and grease to the county here. A few 
years ago he was selling about 12 barrels of Mystic JT-7 85-140 Gear oil 
each year to the county for their mowers.  He suggested they try Mystic 
Centra-Lube, commonly called corn picker grease 00 weight.  He went to 
selling 2 barrels of JT-7 and 1 barrel of Centra-lube a year to them.  I 
use Centra-Lube in all my gearboxes, and have even put it in a 
Roadranger transmission with a leaking PTO.  It has to run a few minutes 
when cold, but it shifts like any other 13Spd Roadranger I have driven.

In extreme cold weather (-25 deg F), gear oil would be recommended for 
bearings.  I agree with Steve's link on the use of grease vs oil.   But 
that is in a perfect world.  Tractors are like boats, they aren't right 
unless they leak a little bit.  I will use oil in transmissions and 
engines and rear ends.  Grease everywhere else.
