Hello,

When I powered up the lathe this morning, there was horrendous crackling noise coming from the hydraulic system in the back of the machine that sounded like a bad bearing in the electric motor. I powered down, pulled off the top fan cover and cleaned all the gunk around the fan, powered back up and the noise stopped. The motor is turning just fine but I have no hydraulic pressure now. I'm guessing that the noise was the actual mechanical pump that's submerged shattering into pieces...?

I removed the eye bolts that fasten the lid of the tank but with all of the solenoids, brackets and weight of the electric motor/pump, the lid is impossible to completely remove. I see that there's bolts from underneath the lid that's fastened to the electric motor above, but I can't get to them all through the small opening. Do I need to drain all of the fluid to remove this thing? Is anyone familiar with what the mechanical pump looks like or if it's susceptible to failure/breakage?

Thanks in advance for help you can give me!
