I have a 2001 PT 2422 that has the Subaru engine 25 hp. It came new with the 22 hp but since was upgraded.
My auxillary pto - steering pump assembly is a 8 gpm 2500 psi gear pump.
My question is when I replace the pump assembly which is weak, I am thinking of putting a 10 gpm 2500 psi pump to replace the old. The difference in the required hp for the 10 gpm on the new pump is 3 hp which I already have from the new 25 hp Subaru. The attachments from Power Trac are rated from 8- 12 gpm.
I shouldn’t have to worry about power loss for the rest of the machine since it was running on 22 hp from the factory.
I’m thinking that I can upgrade my pump, and in return have better flow for a more diverse attachments from the aftermarket, brush hog, stump grinder, etc and have better results from that which I already have since the pumps on the attachments are rated for 8-12 gpm.
Am I thinking on the right track? Looking for any input before I do this in about 2 weeks. The only downside I can think of is when starting the motor i may have to put a higher amp battery and or a high output starter to spin it over faster.
