Pto shaft

Postby Als » Thu Jan 12, 2017 4:25 pm

I have a new to me 185. Pto shaft was bouncing around like a bearing blew apart, but is the shaft. This is the problem. Bearings are ok, solid but a little noisy. Shaft has no real wear to speak off. That out of the way my question has anyone seen the shaft with a undercut right where the bearing sits? The lock collar is on shaft fine but in front of it is a undercut? Looks way wrong to me. Nowhere for the bearing to sit so it just flops around.

I have not had much dealings with the number series, but that is definitely not normal. Looks to smooth and even to have been worn by locked bearing, though someone may have dressed it up. Looks like you need a new shaft, or take it to machine shop to be built up. Might check with Hamilton Bob's, one of the sponsors at the bottom of the page. I have never dealt with him, but the members that have tell me he is real helpful.

No it isn't wear. The undercut was put in at time of manufacture. It is hardend. Was thinking it may of had like a split bushing there but just doesn't make sense to do that. Have been in contact with bobs, still need to talk to bob tho

The under cut is for a clip ring as a safety back up encase set screws work loose.

I was just looking at the pto shafts on Hamilton Bob's site, and they do not show that cut down area.

I was thinking the drive shaft, I looked at one of mine ,it has a cut like the one you have. I will try to find out why myself.

Aww! Ok. What the devil is riding in that undercut? The OD of the under cut is also tapered. .990" nearest spline to 1.030. Odd. I really dont want to weld it up and machine it if oem and I'm just missing something.

looks familiar,had a service van that ate a shaft on the back axle.
the bearing contact point failed and looked just like that pto shaft.
the bearing race must have been slipping on the shaft'

I do not own a 185. I do have 2 of each 184 and 154. Here's here is what my parts manual has for description and parts numbers. PTO shaft with two bearings the number is 404917R11. PTO shaft with clutch the number is 546651R1. I am assuming that it might be interchangeable.????? Or someone like me thought they had the right part a stuck it in there. I will keep this in mind when I take my one of my 184's apart in the future. I hope someone can clear this up also. I love to see these questions and solutions.

''I love to see these questions and solutions.''

Many of the members here are a wealth of information. Kind of like back in the day were the older men in the community would mentor the young ones.
only theres computers now so the mentors have expanded greatly.

Mike:
I don't want to be argurementive, but, I was a machinist for 40 years and cut and ground many shafts just like these. In fact I cut the gears also. Of which mine here arnt in the best of shape but usable.
This relief/undercut or what ever the propose of it is was without a doubt machined onto the shaft with radius's, chamfers, then case hardend with the rest of it. Way to smooth to be wear from a seized race. I just am trying to make sense of it and wanted to make it right if a piece was intended to be there.
As stated previously it may just be the wrong shaft. It fits and works, except the fit of the bearing over the cut. With no other option I can build it up with * Devcon * and machine it to fit.
I have plenty of time to get the research on this done, lots of things I can do until I have the solution.
I really appreciate the help, and maybe, just maybe I will be able to help and share with others sometimes.
