I want to replace the bearings in my IT175G. It has tapered roller bearings, not sure if this is OEM or aftermarket. Anyways, got the top cup out but do you think I can budge the lower one? There is a pair of notches in the mounting recess to enable a drift of some sort to get a purchase on the cup, but there is no more than a poofteenth of an inch of the backside of the cup available and nothing I can come up will lodge well enough to actually let me wield the big hammer. Is there a trick to this? I guess heat may help?

if you have a arc or mig welder, just weld a bead all the way round and the cup will fall out.
-
Use a dremel and put a small grind slot in it, then strike it with a chisel. Will split the bearing at this spot and fall off.
watch this video, good tutorial :

Make sure you wear safety glasses, I can show you the entry hole and the hole they cut to remove a steel splinter from my eyeball!

Thanks for the info. Both of you! ;D

It's also a good idea when hitting hardened steel parts with a hammer and chisel to cover the bearing with a piece of cloth. this will stop any sharp splintered pieces flying off and sticking into other parts of your body!
The run of weld method is preferable.
