I want to remove the brake drums on my 77. I&#039;ve taken off the cover and the band.  The manual says to insert a 1&amp;quot; square piece of steel into the center of the drum and loosen the nut.  Question, before I start pulling on the wrench:  is the one on the right side of the tractor a left-hand thread?  Both right-hand.... or.....?
Also, once I get it off, are the oil seals relatively easy to replace?  Thanks very much for any info.
