Looking for some quick hydraulic help!

David, it looks like your pump is from a 1811 or early cyclops. It is not from a Super. Wrong input shaft.

Art,
You still have that unit apart?
If so, could you post a picture of the back side of the unit and tell me if it looks like this one, with no holes in the mounting flange?

Picked up this ported unit a few years back and just now got around to checking it out.
Unknown what it came from originally, it has remnants of grey paint on it but no sign of any yellow.
Numbers on the tag say 90-1225-CCW and A-88-49-14816
No idea what those mean either except the CCW probably means counter clock wise.
Thanks!

The 90-1225-CCW came out of the cyclops tractor. But probably others as well.

That's not a cyclops pump, as they have a splined input shaft, or at least I have never seen one without a splined input shaft on a cyclops.

No holes in the bottom means it has the integral motor swash plate instead of a separate one that bolts on. Not sure when that change occurred.

If you check the numbers Matt, you'll find the pump does indeed fit the cyclops series machines! The body is a different story!

So.....
Bottom line here is will it swap into a QL w/no issues??
Drive Input shaft is same
I don't have another out of a tractor at the moment to compare it with.

Mat....is the integral motor swash plate a better deal/improvement??
What does it do? less internal parts or something like that?

Should go right in since the input shaft is not splined.

I don't have anywhere to check numbers on the pump. What model cyclops does it "fit" without changing the the driveshaft coupler? I have never seen a hydrostatic drive cyclops machine that did not have a splined input shaft, and the parts lookup supports this. What am I missing here?

A couple less parts. Not sure it is better or worse, just different.

For example, the 1860 had both drive lines. The early ones had the 82 series style and the later, splined.
