Super Hydro Units
 

Could somebody explain the difference in a super hydro unit and a standard GT hydro unit. It looks like the only visible difference is the splined input shaft. Is there a gearing change for the larger size tires on a super or do they have a different mount pattern?:bigthink:

Gearing changes to accommodate the larger tires on the supers.

There are no gears inside a hydro pump. there for no way to change the "gearing". The differences are as follows.

The input shaft is splined.

The out put shaft has a different tooth count on it so it will mesh with the different reduction gear in the reduction housing.


I have a thread on here somewhere with pictures of one that I disassembled. If you can't find it let me know.

:bigeyes: I had the complete rear end and hydro unit in my mind. Yep your right no gears in the hydro unit itself. :bash: Think I need my nap.

Do you remember what the heading was called? Can't seem to find it. Thank You Kelly

Let me look for a minute ,I am trying to find it myself.

Thank You.

Here it is. Good luck That pump is not a "super" pump, it was from an 1811 if I remember correctly. I am doing a cast iron conversion on the 1872 that is for.

I'm not highjacking this thread but, did you complete the the CI conversion Joe? Great pictures of the pump guts.

Sort of. I have the pump back together and mounted on the rear. Now I have decided to put a fine spline set up in it. I am looking for a gear drive rear to do the same with. I am hoping to find one soon. I have never set a rear end up before. So my buddy said he would show me on one , then watch as I do the other. I have all the fine spline setups a person would ever need, just looking for the gear drive.

The 1872 has been put on hold for a while anyways. I have something else I have been working on getting parts for. I like a gear drive for mowing so I am going to do something no one else has . When it starts coming together I will start taking pictures and post them.
