How to Get PTO Shaft Off Implement?

[TerryR]

My Peruzzo ditch and bank mower (5 years old) has failed bearings on the output shaft of the gearbox:

I've ordered a replacement gearbox, and am making progress getting it torn down. But I'm currently having trouble getting the PTO shaft off. I don't actually know what the connection of the shaft to the gearbox is. I've removed the nut on the bolt on the hub, but can't figure out how it comes off:

Does the bolt have to come out first? I tried gently tapping it out and it doesn't seem to move.

Also, I can't figure out how the guard comes off. I'm not sure I need to, but it seems like it would be helpful.

I've removed the silver ring, and it looks like the black part should slide off the yellow part, but I can't get it to move:

Any suggestions about how to get this apart would be helpful.

Pull the bolt out and then slide the shaft out.

They are many variations on the guards but they do eventually unsnap and come apart. You tube has several videos of different guards being removed.

If it's not a spring loaded pin holding the u-joint to the shaft but a bolt, I would turn the head side to where I could get an impact or a drill on it and see if I could get the bolt to start moving by backing it out if not I would drive it out with a smaller bolt or a punch.

I banged on it a couple of times and it didn't seem to move. I guess I need to get more serious about it. Thanks.

Thanks. I found one that seems to show how it comes apart. I'll give it a try tomorrow.

The nut was fairly tight on the bolt, so I don't think it is spring loaded. The head of the bolt is strange. It's round, no bigger than the diameter of the bolt if that, with two flats cut on opposite sides, so it won't take a socket. I'll try a wrench on it to see if it will turn.

Sure sounds like a spring loaded pin that has frozen up or has seized up.

PB Blaster time I'd say.

Put nut back on threads and run down until flush with threads. Get a rod and an impact implement (Hammer), and seriously try to move it. Sounds like a wedge lock situation. Has to be driven out from thread end. If you get movement, spray with oily stuff and tap to and fro and keep spraying and you should be free.

Pr use a suitable sized punch that won't bugger the threads.

Sounds like it may be similar to these, PTO yoke bolts.

Loosen the nut drive it down, remove the nut finish driving it out.
Some times you have to remove the nut completely and just drive the pin out as once the taper starts to loosen you cant hold it to remove the nut.

I had one of those tapered bolts on my small tiller. After you take the nut off the other end it's just a matter of driving it out.

There is nothing to get ahold of because that's the way the bolt is made. spray it with penetrating oil as has been mentioned and come back in 5 minutes. And yes get serious with the hammer and punch.

As far as the guard is concerned I took my cordless reciprocating saw made 2-in slices in the hole so that I can fold back the guard to get my hand in there. After you're done you can fold those back.

To the OP I forgot about the second part of your question regarding sliding the PTO shaft guard, most of them will have 2 or 3 little cutout slots with tabs that have to be depressed in order for it ro be slid back, others will have a couple of round plastic screw heads with a slot for a standard flat screwdriver, you will have to turn it about a half of a turn to release it and it will rotate so the head of the plastic screw lines up in the slot and will then slide back and allow the plastic guard to be collapsed or slid down the shaft.

Thanks, LouNY,

That did the trick. I found a video on the Eurocardan model I have. Turns out once you have the silver- colored ring off, the bell just pulls off. It's a bit tight but if you work it back and forth a bit it comes right off.

Thanks, Roustabout, and others who made this point.

That's exactly right. A single, more serious, blow on the thread end popped it right out. As several said, the bolt is tapered, so once it moved a bit it was loose. Then the yoke pulled off the shaft with no problem.
