Cracked Cat 310 Pump

[Randy]

Has anyone ever seen anything like this with a Cat 310 Pump. In 42 years of being in the car wash business I've never seen anything like this. I told my customer lets let it run until it uses up all of it's nine lives. This pump is about 4 years old.

We have a cat 3535 in one of our ER that came with the car wash, broken back cover, looks like a rod broke and took out the cover

This pump is still running fine, no noise, no oil leaks.

That's amazing, would have at least expected an oil leak if not worse

A few years ago I had a 5CP pump and the rod broke. It cracked the back cover and all the oil eaked out. When I discovered it the pump was still running and producing about 800 psi!

Did you call Cat to hear what they had to say about it?

Nope, it's out of warranty.

Of course, but maybe they would like to know about it if it's a defect. It sounds like it may have been built during the Covid lockdowns and it makes me wonder if they compromised on something.

My first guess would be that the belts were changed by screwdriver. I've been guilty of that myself a few times but luckily no case fractures. Second guess is hydrolock. Unloader malfunction, a d¡ckhead customer pulling the trigger rapidly and repeatedly, or a sudden tip plug up.
Third and final guess is an uneven mount surface combined with over tightening of the fasteners.
I'd sure love to know the answer to that one!
