I have woods 750 backhoe with a cessna 24503 LZA hydraluic Gear pump.The body of the pump cracked. Looking for new body or replacement pump. Does anyone know what the replacement pump would be ?

Your obsolete pump is a 2.10 CuIn - we have a replacement with a 2.33 CuIn, 25504-LSC, cost 377.47 there is only one in stock in the US, 15lbs. The pump that is in stock is the last one - after that it is back to the drawing board.

Your porting is side 20 by side 16. The replacement pump porting is side 20 by side 12. The pump is 3/4" wider.

I am using a L2 gear pump number 25506 and I need to know what horse power would I need from a gas engine?

You will want to look at the required "Input Power" to get the desired or rated performance for each specific pump in Eaton’s literature. We have a link to the PDF on the product pages. The information you need is on pages 24, 25, and 26.

I am wanting to build a log splitter with as short a cycle time as possible while maintaining 27 ton press. What pump type? Does the valve type matter?

It is generally cheaper to buy the whole unit as one than it is to buy the individual components. However, you will want an 11 - 13 gallon, 2 stage, 3000 PSI gear pump. The Log Splitter Valve by Prince is a good choice.

I have an old Cessna 24509-LAA. If anyone out there knew what the cu. in is, perhaps I could find an "equivalent" one.

The modern version of your pump with slightly different porting is the Series L2, 25504-LSA.

I have a Cessna 24500-500C. Are there any "kits" to fix it? If not, what Eaton pump would match and or provide slightly more capacity. It is for a Henry Backhoe which is mounted on an International 300 Utility tractor.

The number you gave is a casting and not a part number. On the mounting flange ear there should be a number that starts with 245XX - xxx. So it is 5digits - 3letters. With that number we could get seal kits but those are the only parts available.

More than likely you will be cross referenced into a 255.. - XXX pump. An L2 Pump.
