power steering for B6100

Its a taper fit clamping ring. It fits over a thin walled hub and when you tighten the bolts it pulls the two flanges together squeezing the ID in against the wall of the hub and clamping it to the shaft. Similar in concept to a taper lock pully.

Man I’m learning so much with you guys!! Thanks for the advice excellent video teaching us of all us n the dark something new.

I've been studying up on the Fenner Drive and that really sounds intreging. I'm going to look into this more.. I'm collecting parts right now but I use the tractor so much, that I'm afraid that there will be snow on the ground before I actually install all this

Fenner's keyless bushings use the same taper lock concept.

I imagine that spline is an ISO standard. If you know the size you can probably buy a matching sleeve.

If you have a mic measure the OD of the splines and post that dimension along with the tooth count. Maybe I csn find a matching sleeve.

I’ll do that as soon as I get off work this afternoon. Thx!

The sleeve has no taper; the shrink disk consists of two parts w/ a shallow matching taper. As the bolts that connect them are tightened, the inner diameter of the disk contracts, clamping down on whatever the disk is placed over.

Since the taper is shallow, the amount of shrinkage is small - a few thousandths iirc. When I machined the drive sleeve, I made it a hand wringing fit over the splne and machined it from Stress-Proof steel (hardened 1144 alloy) from McMaster. This allowed the shrink disk to securely clamp the drive sleeve to the taper, yet when I removed the shrink disk I could readily remove the drive sleeve again, so the compression was within the elastic limit of the sleeve.

Compared with the difficulties of machining a metric spline in my home shop, this was a simple solution, and has been trouble free for the 10 years it's been in service.

I'm counting 21 splines. And then the mic shows the diameter. Any chance I could purchase a sleeve from you that would work with a shrink disc? I have this idea to add front connections and a quick change plate for some different attachments. A separate hydraulic system such as this over the onboard system would really bring my little tractor into the modern day era and open up tons of good side work here in my area. And I think I see a threaded hole behind part of the flat washer too. Thanks in advance!

Thanks for the measurement. That's a basic match for a DIN 5480 spline but not conclusive without further inspection.
Basic specs are :

Nominal diameter: 18mm
Module: .8
Tooth count: 21

However I could not find a matching sleeve.

Your machinist friend should have no problem making something that would work with a shrink disc. I would be thinking cylindrical hub with external key for a chain coupler.

JFYI - thats a caliper not a mic.

It’s all I had to measure with. I’ll give my buddy a call on the sleeve. It appears that under the washer are bolts attaching the spindle to the pulley. With that off it may be just as easy to have him turn a spindle that will accommodate the chain sprocket on a key way.

Did you mean bolt holes under the washer? I believe that pulley is splined to the crank and the nut holds it in place

So the splines I see aren’t part of a bolt on flange? They are part of the crankshaft?

I beliece that to be the case. What I dont understand is why your pulley does not have mounting holes for the PTO adapter shown in the parts book

Here is a picture of the crankshaft. The pulley is keyed (not splined as I thought) to the crankshaft and the splined end of the crank protrudes out the front.

You're amazing on this stuff!! So a sleeve to fit over the spline shaft end and a shrink disc that is keyed to allow the chain drive sprocket to ride next to a chain sprocket on the intermedary shaft that has a chain drive sprocket that will mate up to a chain drive sprocket on the shaft of the hydraulic pump. Each union is carried by a double roller chain to allow for a small amount of flex in the shaft alignment. Do I have this correct?

Exactly. This looks promising.
