On reassembling gear box on my rotary cutter [its not green but principles should be universal] ---should I pack the bearings in grease like a wheel bearing? just for good measure...use 140 or 90 wt gear oil? [I have no book]...how much backlash on the gears? 1/32? 1/16th? can I accomplish that with shims?...the thing had no shims when I took apart. The thing was way tight when I just assembled dry. Shims and new gaskets? or just new gaskets? This is kind of a tedious job where either too much or too little can be unworkable. Any comments appreciated.

The other thing that I meant to mention in my other post, is that I have found over the years, that if you can "vent" the gearbox, it will help eliminate some of the minor oil leaks. As the gear oil heats up from use, vapor pressure builds up inside the gearbox, and, without some type of vent, can cause enough pressure to build that oil will be forced out around the seal.
Just a thought---yours may already have a vent.

Go to your dealer and get 6-10 new shims (per gearbox) of various thicknesses and use the �grease on the gears� method described here by Robert . You�ll have to assemble and dissassemble dry a few times until you get it set right. We set the backlash on our cutters as close to 1/8� as we can get. It won�t hurt to pack the bearings if you like, but you don�t have to. We don�t pack ours. If fact, if we have a seal going bad and we don�t have time to stop and fix it, we�ll run cotton picker spindle grease in the box instead of gear lube. It will thin out enough to lube everything good but not so much that it comes out around a bad seal. Good luck.

I personally haven't had any experience with gearboxes on a rotary cutter, but have had LOTS of experience with similar types of gearboxes used in other applications.
Some use metal shims to set the gear lash, others use a combination of gasket thicknesses to take care of the lash. The best way to tell what the lash is, is to coat one of the gears with grease, then assemble and turn a couple of turns, disassemble, and see how they mesh---the grease will show what the "footprint" is, and where adjustment is needed. Hope this helps.
