Made an interesting observation on my Attex. Engine and trans removed,standing on the left side of machine looking down into it.On the right frame rail,the front and middle axle's flanges are on the "inside" of the frame rail(I can see them).On the rear,they are on the "outside" of the rail (all that can be seen is the back of the bearing and the very top lip of the flange,protruding from the aprox 2 1/2" dia hole in the frame).Either orientation seems to be ok to me,was just wondering what the "standard" might be? I'm making some new axles and believe this to be the time to determine this and adjust accordingly. Thanks.
