3600 PTO question. Live? Independent?

[lorandroehl]

Thanks for the replies. Sounds like this is a 2 stage clutch with the PTO stage not functioning properly. I did speak with somebody in the service department at a New Holland dealership today and described the problem. He told me sometimes the PTO clutch will "hang up" and act like this. He suggested I hook up a PTO driven implement like a rotary cutter, run this for a while, and this may "knock loose" the PTO clutch. Has anybody done this? I suppose it can't hurt, but is it likely to help? If it is an adjustment problem what type of adjustment is needed? Again thanks for the replies. I have a feeling the PTO clutch has seen its better days and I am headed for a new one.

I'd adjust freeplay to minum setting.. or maybee a hair under, then see what I had.

pto section may be froze up.. or clutch may be worn out of adjustment so there is not enough trow to seperate..e tc.

might put a pto load on it, block cluthc a day, set in seat, and useing a remote starter button , bump engine over a few times.

tranny in neutral of course.

if it is simply stuck.. that might pop it loose.. otherwise.... splitzy

A 3600 with a 6 speed transmission will always have a single disc clutch. And that PTO will be transmission driven, not independent. You will not find a 3600 with independent PTO, only 8 speed models with live PTO, or other configurations with transmission PTO. The smallest X600 series tractor with independent PTO would be the 4600, or if you want to pick nits, the 4100 that was offered at the same time.

Rick, the exerpt from the Nebraska Test is for a 3600 with 8 speed tranny and it says it has a single plate clutch. I guess it must be a transmission driven pto then or the report is incorrect.

And the original post said the pto can be engaged without using the clutch. If the clutch is toast, how can the pto transmit power? Not trying to pick a fight, I'm just trying to understand.

Many new tractor today including TC-30, T1520 offer transmission driven pto as the simplest form of power transfer to the rear.

8spd twin stick would be a dual clutch on a 3xxx like that.. or independent if the 4xxx

everything I have in manuals backs that up.

would like to see a resource that says otherwise..

i've seen plenty of odd things mind ya.. so not ruling naything out.. but....

your right all 3cyl 8sp dry drum breaks equals two stage clutch and 3cyl 8sp with wet breaks equals hyd clutch pack

Double clutch 3 cylinder Fords ALL came with 8 speed transmissions behind them. I didn't say ALL 8 speed transmissions had double clutches in front of them; most, but not all did. There are (a few) 2000's and 3000's out there with 8 speed trannys and single disc clutches for sure, and there are model codes for that configuration. There may be model codes for 2600's and 3600's set up the same way, but I don't know for certain and don't have a resource here at home that I trust enough to refer to.

The PTO can be engaged by just moving the the control lever towards the rear without stepping in the clutch. The lever moves easily with no grinding. There is a little vibration in the lever when the PTO is engaged, but I would not call it grinding. With the tractor shut off the PTO shaft is easily turned with the PTO disengaged, but I can't turn it with the PTO engaged. Stepping in the clutch makes no difference. With the clutch stepped down all the way the PTO shaft is still not turnable by hand when the PTO is engaged.

I'm still confused. If the pto clutch is stuck to the flywheel, why does the OP get no grinding when engaging the pto? Gears worn off to nubs (a little vibration)? But can't turn PTO with the engine off, and PTO engaged?
OP, you'll need some kind of load on the PTO to figure out the problem. Know anyone with a brush hog or tiller?

That's it.

With no implement attached to the PTO, the shift collar doesn't grind against the PTO shaft, it grabs a spline and engages immediately because there is no inertial load (to speak of) to get turning. Attach a chipper or rotary cutter to that PTO shaft and the OP would hear plenty of grinding and probably wouldn't be able to engage it at all with the tractor running.

Problem solved. I decided to to do some adjusting and see what happens. What could go wrong? I turned the linkage rod in about 3/8-1/2 inch and voila the 2 stage clutch now functions properly. I have not attached a PTO driven implement yet so that will be the next test, but for now it seems things work correctly. I guess it may need some additional fine adjustment but it doesn't look like a split for now. Thanks again for the help.
