Having to run a PTO pump limits your options. To do any reasonable amount of work at that RPM, you need fairly large pumps.

Prince makes reasonably priced PTO pumps. although they're single stage. Does your tractor have auxilliary hydraulic outputs?

thanks josh really want to stay with a pto powered pump only have 1 tractor with remote hydralics with the pto style pump could use on serval of my other older tractors with remotes any help or recemondations would be much appreciated will check back later tonight

Define old. The pump is turning much slower than it was designed to do and could be bypassing oil internally, could have stripped keyways, etc. You need to have it checked by a hydraulic shop.

Also your bargain Log Splitter must have had a Directional Control Valve and it probably has a Relief Valve built in. Are you sure it is working?

Again you may have to pay someone to check out the components.

Something like this will be your best bet for a new pump.

You'll need a torque arm to prevent it from spinning, but basically it just slips on the PTO shaft. They're 6 spline, so if you have 21 spline, you'd have to check for availability.
