PTO pump fried. Looking at a new one?

Title sums it up. Something in the pump is making a loud whineing and clattering noise and the pump will cut for a few seconds at a time and drop all pressure. I currently have the following in my rig BELA26S20 by BEZARES USA - BE Series 26 Gallon SAE B 13 Hydraulic Gear Pump but i know its a pretty weak one and have always had issues getting my end dump bed up when fully loaded especially on a nose load. But im not sure if just slapping a stronger pump on is a good idea and will fix my issues or if i should just do like for like and focus on a better because the PTO itself is what matters or how that all works.

I am running a 55 gallon pony tank on the side so fluid should not be the issue.

Any advice would be helpful!

 

Ill look into it then. Motocross gave me a good lead too. So what ends up on the transmission is going to depend on what i can get my paws on and what my piston is rated for. Was going to call mac trailers monday and see what piston they used on this one and match a PTO and pump to it.
