Front PTO shaft options

[b454rat]

Not sure what section to put this in so I'll try here. I'm in the process of putting hydro steering on my B7100. The steering gears are pretty much gone, so figure now be the time to do it. Rather than use the tractors hydro, going with a separate system, might be a pain and a blessing at once lol. I want to run the pump off the front of the tractor, there is room, and pumps seem to be small enough to fit behind the bumper. The 7100 has the splined hub attached to the balancer, but is the 21 or 22 spline for the unobtanium snow blower shaft. My 6100 has a snow blower, but doesn't have this adapter, the shaft just slides on the splines on the balancer itself. I'm looking for a way to mount a shaft to either directly to the balancer, or the adaptor. Seems both shafts are unobtanium.

See this thread that discusses several options

B7200 hydraulic steering

I'm in the process of purchasing some hydraulic steering bits from a BX from Daryl at Mossy Creek Outdoors @Mountainman - planning to attempt to fit it to my B7200 HSTD 4WD hydrostatic. I found the plumbing diagram below on another thread - I think it was done by @North Idaho Wolfman -...

No balancer on that engine just a pulley
If you have the adapter that uses the three bolts to mount to the pulley, you can use a Lovejoy that fits the adapter and use that.

How would the lovejoy bolt up to it? It has the 18mm shaft sticking out.

L175 engine front shaft

I know this has been discussed in depth. Does anyone have a definitive answer where to get a female shaft with the appropriate splines to attach to the front motor shaft?

See discussion about "shrink disc" in various threads...

The lovejoy you would use would clamp onto the adapter not the crank splines.

I looked at them yesterday and still don't see how they would go on. Must be Im missing something lol.

Here's a couple of pictures of the adapter I made for driving a hydraulic pump from the front spline on our B5100. The round aluminum part is a shrink disc that elastically squeezes the adapter onto the spline. The adapter is a piece of stress-proof steel, which is a very close fit onto the spline.

Wanna make another one lol.

Here is one:

You can use this style too just drill holes and attach to adapter.

 

[b454rat]

So just use the 3 bolts to hold it, not the splines. There isn't gonna be alot of twist force or whatever want to call it....

'torque'.... unlikely , little 16HP engine and a small pump.

 

[b454rat]

I think i found a shaft, even comes with snow blower lol. Next problem (more of a question) is what pump do I need? JD won't tell you a thing, so don't what size to get. .50 CI, bigger smaller, don't want it too fast, but don't want snail steering either. Searches have most using a p/s pump or using the tractors...

I would think that 2 gpm should be the maximum which according to specs I have looked at would be around .18 cubic inches at 2000 rpm. Lots more folks here with a lot more knowledge than me with hydraulics.
