Boring Head For 8520

Turns out the shaft was 3/4" so had to order a replacement.
Problem now is get it out.
Are these standard thread or left hand thread ?
It's snug so don't want to break it trying to get it out, especially trying to unthread it the wrong way.
Figure I'd hit it with hot air to try to loosen it.
Any other suggestions ???
 
Should be regular right hand thread.
I would try holding the 3/4" shaft in a bench vise and put a bar in the boring head and give it a SOFT rap with soft hammer.

On edit: I would just try tapping the bar (for leverage) with my hand first.
 
Tried that, no go, it's on there pretty snug.
Figured I'd better check which thread it had before going harder.
I was pretty sure it would be regular right hand threads.
Figure I'll hit it with a little heat from my hot air soldering station see if that will loosen it up.
 
Well, got the old shaft out. Turns out it whoever put in on used lock-tite.
New MT2 shaft in and ready to go.
 
Have you tried it out yet?

Loc-tite may be a good idea.. hadn't considered it before. To get mine back into the tool box - I break it down each time.
I'd have to readjust some things but it might be better to keep it assembled? idk...
 
Didn't have time to try it out yet.
I'd ordered a MT2 taper shaft from ENCO, even with the head on it fits in the plastic box the shaft came in so I'm storing it there.
I may lock-tie mine again as it comes loose easy on the new shaft.
I did put in a boring bar and spin it in the mill.
 
I ran across this thread and was curious if you ever got a chance to try out the boring head?
 
Not yet, but soon.
Neighbor needs a new bearing block for brush mower PTO shaft.
Ordered material today and will need to bore out for bearing.
I'll p0st some pics when I get to it.
 
I'll try to be patient.. :cool:
