22 gpm pump adaptor for 16hp cast iron Briggs & Stratton engine.

[90cummins]

I have an old 16hp B&S cast iron engine model 325431-0135 that I would like to use on my log splitter.
I have looked for pump adapters that directly mount on PTO face with no luck.
Is there an adaptor that will mount a 22 gpm pump to this beast?
I would really like to keep this old iron in service. They sound and run very smooth and crank out 25.8 ft-lbs of torque (13.3) hp at 2700 rpm.
Thanks

Do you have a picture of it, and have you measured the bolt pattern?

Surplus center has a bunch of different ones.
This one is for B&S up to 16hp but confirm your bolt pattern! SAE A 2-Bolt Gas Engine To Pump Mount - Long | Gas Engine to Pump Adapters | Hydraulic Pump Mounts | Hydraulic Pumps | Hydraulics | www.surpluscenter.com

I do. The photo is the PTO side without the closure cover.
The OD of the closure cover Is 6.5 inches and the bolt circle outside that is approx 7-5/8.
I checked surplus center and nothing looked compatible.

Parts manual,
http://www.thepowerportal.com/ipls/ipl.htm?md=325431013599_IPLURL_LO.pdf&attachment=1

But doesn't list dimensions. Those are in the repair manual, which costs $20.

I have the repair manuals and will look.

Older engines weren't designed for direct adapter mounts they required a foot adapter.

Is this a 2 stage pump for a log spiltter or a single 22 GPM gear pump?

Before spending any money, check the HP requirements for that pump. Unless it's a two stage pump, you don't have enough HP for a pump that big.

According to this, that 16hp motor could provide about 16GPM @ 1500 PSI.

From here:
Horsepower Calculator - Metaris Hydraulics

Formula: HP = PSI * GPM / 1714
PSI is gauge pressure in pounds per square inch; GPM is oil flow in gallons per minutes.

Rules-Of-Thumb:
Horsepower for driving a pump: For every 1 HP of drive, the equivalent of 1 GPM @ 1500 PSI can be produced.
Horsepower for idling a pump: To idle a pump when it is unloaded will require about 5% of its full rated horsepower.

I wouldn't run much less than 2500 PSI for a log splitter and that would require 32 HP at 22 GPM, using that calculator Moss provided.
