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."


Does the pump spin if you run oil (or air) through it?
