The coolant pump on my Mazak M4 has slowed down to the point I can pee that
fast.

I found a replacement at McMaster Carr:

Cast Iron Coolant Pumps for Foreign Machines - above tank. part number
99875K74 for $400.

OUCH! Anybody know of a less expensive replacement for a coolant pump? FWIW,
the M4 has a lot of line to go through to get to the two turrets.

Or, is it worth taking the pump apart to see if its just gunked up? I put a
water hose on end of the line and backflushed it today - no problems found.
The pump is developing very little pressure.
