Just bought this;

I bought two large frames last summer. And, after getting my HT 23 going, I needed parts for my HT 20.
When I saw the ad on C/L I just about bought this site unseen! ( it was cheap!)

Now, the problem is, this is too good to be a parts machine.
Aside from that fine patina, it's a pretty solid and complete machine.
It's big problem is the input shaft to the hydro is worn.
I'm thinking, pull the pump, disassemble, TIG weld up the shaft and turn it?

Do you have a photo to show how bad the shaft is?

Sorry no picture of that yet.
I've only seen it in the daylight briefly!
Got my hand under there and shook the yoke on the shaft.
Seemed like an 1/8" of slop to me.

Another picture;

Love that metal dash!
And all the decals are in real good shape too.

Thanks,
Joe

Rather than weld it have you thought about brazing it with hard rod? I had some hay baler pick up bars that were worn bad. The welding shop brazed them up while I slowly turned the bars. Then they ground it back down to size again. They did not have to fit precise as it was just a loose fit. Something to think about.

Sorry but that's the last thing that should be used on this problem.

I'm not a welder.
I'll take it to a professional.
My machinist is next door to him.
I'll put the shaft in their hands and trust them!

It's always good to plan ahead, but IMO you need to pull the fender pan and take a good look at the driveshaft , the shape the yoke is in that goes onto the pump shaft. I have found on a couple of my 1886 that how far it engages onto the input shaft was the issue, I addressed the problem on one with a two piece driveshaft, and in another by removing the thru bolt on the drive shaft yoke, crankshaft end, if it doesn't have set screws drill & tap it for a couple , the crankshaft is keyed into the yoke and you have more length to slide it back onto the pump's shaft, I agreed with WilburJ as far as your plans for the shaft, you may find it cheaper to look for a good used pump ( if the input shaft is the problem) or a used input shaft. I have good used parts for the Eaton pump , I can hook you up with a good used shaft if you decide to go that route. Good luck with your project 1886's are nice units.

I took a look at it this morning, before heading of to work.
The PO took most of the bolts out of the seat pan.
But, there is two nuts on studs to secure the seat pan to the column.
They don't look like fun to remove!
My HT 23 just has unthreaded studs there.
Maybe I'll take a crack at it after work.

Here a picture of the shaft; image.jpg
Measures about .850 at its smallest diameter and about .875 at its largest diameter.

My HT 20 and HT 23 both have disc brakes at the wheels.
This one has a single disc on the side of the tranny.

If your going to fix this you need to pull the rear end then take the pump out and take it apart.

So, the weather has warmed up a bit.
And, I pulled the engine out of this today.
When I bought it, the seller told me he did have it running.
But, when I started removing the drive shaft, I could only turn the engine about 5 degrees.
And it felt really bad!
So I added some oil to the cylinders and let it sit.
Today I found the problem! Bad walnuts! About two dozen packed in tight behind the flywheel!
Turns over nice now. I think it will be a good running engine!
Next step is to remove the rear end.
