I was just tearing down an old log splitter (I got it for $60) to use the
mechanic bits for a hydraulic press. The cylinder may be worth what I
paid
for the whole thing. It may not. LOL. The control valve was leaking,
but
when I started tearing it apart I found it was not leaking. There was a
cracked fitting. Ok. That's easy enough. Its not even cracked at the
valve. it was cracked (and broke off during disassembly) at the next
fitting
a wrench may just take it out when I get to it. I spent a good half hour
cutting the cylinder out with water running on one side while I cut the
metal straps and braces on the other side with the torch. Hopefully I
didn't cook any seals.
Anyway, I got to the pump and it was one of the easiest components to
remove. I unscrewed the belt tension adjusting screw, and it slid right
out. Nice... until I started scraping the gunk and dirt off to finds that
they had used a steel drive pulley, and welded it directly to the shaft of
the pump. Sigh. Looks like its going to be the hardest part to
repurpose.
The only thing I can think of is to find a way to clamp up the pulley on
the
mill, and spiral mill the hub out hoping I have enough shaft left to be
useful when it finally comes free.
I'd just reuse the pulley, but its got a huge chunk out of one side. It
would eat belts.
The old Briggs gas motor was pretty rough. That's ok. I plan to use a
continuous duty electric motor on it anyway.
Chuck the motor up on your mill..and turn the motor on, while using
the mill to cut off the pulley. Its not rocket science. Finish up
with a file and Bobs your uncle!!!

Well that would be great if I was salvaging the motor.
The motor drives the pump..right? The pulley on the pump is welded
on..right? Mill it off.

You talked about spinning it up. The pump is spun by the pulley that needs
to come off. LOL. I already said, "The only thing I can think of is to
find a way to clamp up the pulley on the mill, and spiral mill the hub out
hoping I have enough shaft left to be useful when it finally comes free."
Ah! Ok..I see where I went wrong. Indeed. Thats a tough one. One
could...I suppose...put a valve on the input/output lines, put the
pump in the vise, put it in the mill and then close the valve, mill
off some pulley, open the valve, turn the pump a bit, close and mill
and so forth. You would need a valve and a pair of hoses and simply
put the valve in between the input and output lines and fill the
hoses. Id probably clamp the shaft as well with something so the shaft
COULDNT move in case there was some leakage (and there probably is) in
the vanes.
You could do the same simply turning the shaft each time without the
valve and then finish up with a file. Not a particularly elegant
solution and it would take a half hour to actually machine off the
pulley. Where is the weld? On the far end or on the pump end of the
pully? If its on the far end..stand the pump up and machine off a
quarter inch of shaft and pulley..machine off the weld so to speak. If
its on both sides....doing the first thing I suggested is about your
only solution. Never give up...never ever never give up!! (Grin)
