Tough PTO coupler removal and Replacing PTOshaft

1. Is it normal to need a hammer to put the PTO driven implements on and off the PTO Shaft? It takes me loads of time to hammer on and hammer off and I think perhaps my shaft is just not in good condition. Are there any tricks or tools to remove a tough PTO coupler (if that is what the component that hooks to the shaft is called)

2. How hard is it to replace the PTO shaft on a Farmall 100. Will it drain a lot of oil? Are there any other parts I need to replace

Thanks Ramon

It is a lot easier to fix than replace.

Listen to these guys, Ramon, they know what they're talking about. I suggest, if you don't have one already, to get a set of files, one for fast removal and one for fine cutting. Use them on flat spots, dinks, cuts and mashes. Check the coupling as well. I have the same old beat up shaft that came with my tractor and I can now hook up and disengage the PTO coupling by pulling it with my hands and sometimes wiggling it a bit. That is, of course, when the whole shaft doesn't come unscrewed from the gear wheel and comes off with the coupler. (see my post about PTO gear trouble.)

Do all PTO equipment go on that hard? If so, make sure the shaft in the tractor is not burred; clean any burrs, rust, or hard grease off with a file and or sandpaper to get a good polish and oil it up so you have a slick surface. If only one or two implements are hard to put on, check the coupler for burrs etc and clean up the same way. I have a B that has had the shaft replaced, and it is very snug and I need to keep it oiled up and clean or it gets hard to hook up a PTO. My 560 has been used a lot and always slips right on!

It should slide on and off with relative ease.

If you have to hammer them on and off, something is SERIOUSLY wrong with the coupler, the PTO shaft, or both. Flashing red lights and warning sirens should be going off in your head!

Take a good hard look at both the shaft and the coupler. If they're rusty and dry, clean them up and add a thin layer of grease to both. If you haven't wrecked anything by beating the bejeezus out of them, they'll slide together like BUTTAH!

You also should be able to tell if any of the splines are mangled. Clean them up with a file.

A slight twist in the shaft may not be noticeable, but the splines should be straight. If they aren't, someone put one heck of a load on the shaft and twisted it. You'll have to replace the shaft, and possibly some other internal parts.
