My D6H series 2 duo cone seal on final drive started to leak does the hub have to be pressed on and off.
You will have to press the hub off (pretty much just to get the spindle bearing off) but you will not have to press it back on. I'll find some pics and send to you.
I can split it on the dozer how many tons of pressure to press on and off
Should be less than a ton, it is just the bearing holding it in place, #2 in the pic below.
