Mine was real easy to take apart. However, I've been told that the bolts are "special"... In other words take great pains not to damage them 'cause if you break one off, you will end up drilling and tapping for new bolts. The only other gotcha is to make sure you don't have any nasty burrs on the input shaft so that you don't bugger up the case or brass bearing that it goes through when you pull the shaft. It required a puller to get the fan off mine, but it was simple to make one. Drilled a 3/4" hole through a piece of 1/4" x 2" x 4" plate, then cut out the web on one side so it is "c" shaped and I could slip it behind the fan. I then drilled a couple of appropriately spaced holes and tapped for 3/8" bolts and voila, fan puller. I did a little looking into it, and your is either a slightly older or newer vintage than mine. Mine has little brass caps on the end of where the fan and gear shafts come through the housing whereas yours has plugs. I think the one Mike-hr has/had looked like yours. One of ours had a patent date somewhere, and one of ours has "pat. app'd for" or something like that one we were thinking the "pat. app'd for" one was probably a little bit older. When I re-assembled, I coated the shaft ends with moly grease, then just the non-detergent 30. I think 90 is way overkill since I intentionally NEVER apply more than slight torque. I don't think the oil film is under much pressure as opposed to the rear end in your truck or something. Plus it's colder'n a well digger's @$$ here right now and you'd never be able to turn the thing. YMMV. I'll pose up a pic when I get home of my Western Cheif.
