Default Is this a ported pump?

I was thinking about making a hydro build for a few things. Would be nice to use a ported pump although I dont know how much accessories that can run. (Bucket loader?)

Anyway, is this rear a ported pump?

Thanks!

I'd say no, but the ports would be hidden by the curved suction line in the photo.
It also appears to be the factory oil filter, as all the new replacements do not have a canister filter, they are throwaway spin on like we are used to seeing the last 50 years.
You are not going to operate much hyd equipment with about 4 GPM's full throttle.
Admittedly, you can operate a front loader, but it will be painfully slow
in my opinion.

The "return loop" of the Hydro pictured, hides the areas of where the "ports" would be.

Thanks guys. Yeah I figured I'd need a separate bigger pump for a loader. I was thinking about an old car power steering pump actually. Got to check the psi and gpm. What are good numbers for those to run a loader with also a bucket tilt cylinder?

Gonna fab the loader myself

Here is what I used on my Kwik Way FEL on the 1772 and it works well.

You will want a pump with about 6 gpm at 3000 psi for a satisfyingly snappy loader. You may want a 1500 to 2000 relief valve in the system, but the 6 gpm is a good rule of thumb.

Cool thanks. What does the relief valve do?

A pressure relief valve keeps the desired pressure in the system.
Without one, there is nothing to control the pressure causing things to break,
like hoses, lines, pumps, etc.
Much like the pressure regulator on a propane grill, or an air compressor.

A relief valve is the one component in a hydraulic system that everybody can find to "turn up" the pressure limit. Usually believing it will compensate for a weak pump or motor. It's also the component that they fail to reset after finally installing a new pump or motor and subsequently destroy the new unit or blow all the old weak hoses. The latter being preferable.

Cool

so how does one "reset" a pressure relief valve?

and, would this control work? says it has a pressure relief in it... and if I have a 3500lb pump, does this 2000 press relief mean I am actually limited to 2000psi at the hydraulic cylinders?

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
