F2400 PTO Clutch Replacement - How Big A Job Is It?

[NoJacketRequired]

I've been looking at an F2400 that has a non-functional PTO clutch. That is to say its PTO clutch will not disengage.

How big a job is it to get this working again?

This would be my first foray into the F-series tractors - I haven't had to dig deep into my B-series tractors as they have been fantastically reliable. With this in mind I need to know whether undertaking an F-series PTO clutch replacement/repair is within the scope of my abilities.

Thanks to all for your well-considered replies.

The F2400 doesn't have a PTO clutch.
It's a direct engagement PTO without even a one way clutch.

What need to be done to it depends on what is really going on.

If the PTO is slipping and the tractor movement slows too, then you have a problem with the main clutch, that is a cake walk to replace.
It's the same procedure as a B tractor.

If the PTO is popping out of gear it could be as simple as cleaning up adjusting the PTO engagement lever (not very likely)
To the more likely scenario that you'll need to dive into the PTO shaft shift collar and see if parts are damaged.

As always, your depth and breadth of knowledge in all things Kubota is incredible. Thank you for sharing this information.

I've got a similar problem going on with my F2400. The clutch doesn't want to disengage. I don't think its stuck, it happened all of a sudden. It was working fine, (well, as fine as anything works on a 40 odd year old machine that's had multiple 'farmer fixes' with whatever was lying around over the years), and then suddenly, after some fairly tough long grass mowing, the clutch doesn't disengage, there's grinding when selecting the PTO for the mower blades, and the drive to the wheels doesn't disengage with the clutch. What is interesting is that I tried to adjust the linkage to allow the lever on the side of the bell housing to travel further, there is an adjustment on the linkage to tighten it up and a travel stop, i adjusted both. At first it didn't seem to make any difference, the same issues remained, PTO grinding when trying to select and the machine keeps driving with the clutch depressed, but then a few hours later I was moving the machine back to the shed and I noticed that the the drive to the wheels was disengaging with the clutch again. So I tried to engage the PTO and it worked fine, no grinding anymore. What i noticed was that the clutch was only disengaging at a particular point on the travel, if I press it further, or release it a little it engages again. Unfortunately it didn't stay that way for long, now i have adjusted it to where it seems to hit the 'sweet spot' on the travel and it is partially disengaging, but not fully. I can just about engage the pto at 1500 rpm without grinding but not at 2500 rpm and the drive to the wheels doesn't disengage properly.

Id appreciate any advice, insight, thoughts etc. I inherited the machine when i bought the property, its in pretty poor condition and its really at the point where i have to balance how much more money i put into it in new parts against a replacement machine, but I was hoping to get through this summer season in Australia with it. I can probably manage that by starting it with the blades in the air and the pto engaged and then maybe in the winter i'd take it in two and have a look.

You are confusing a main clutch with a PTO clutch.
You simply need to split it and put a new clutch and pressure plate in it.
Replace the pilot bushing and the throw-out bearing while your in there.
