Gene, Another possible reason to take the bull gears out is that they can be swapped left to right ( I think this is correct on the SH). When my H had a lot of slop in the drive train (poor oil and far too many years of hard work) I improved its drive train tightness by swapping the bull gears. If you look real carefully you can see that one side of the gear teeth is worn, from tractor pulling forward, and the other side of each tooth is hardly worn at all (only is worked when the tractor is driven in reverse). The bull gears are interchangable, so this swap gives almost like new performance, and is quite easy to do. So you get 2 advantages from pulling out the bull gears, easier to clean out the case, and better life from tired parts. I just can't remember if the small pinion gears can be swapped left to right also, but take a look at that possibility, as they usually show more wear than the bull gears. Also waiting for some warmer weather to get out in the barn/shop and start working on iron again! Paul in MN
