PTO stopped

[mike88]

I bought a brush hog when i put it one my n8 i noticed that the pto shaft was a tight fit. I didnt know that it would hurt anything but when i raised the pto something happen maybe a pop and the brush hog went down and tje pto stopped. Tractor runs and moves fine but the pto doesnt turn and the hydraulics dont raise. Anyone have an idea? I havent pulled ot apart yet i jist need something to look for

" I didnt know that it would hurt anything "

Ahhhh yes, geometry & a telescoping PTO shaft.

Cut too short, it falls apart when you lower the bush hog.

Cut to long, you bust the bearing or PTO shaft. Unless you are really lucky and had an ORC that took the hit.

Did you have an ORC on it?

If not, time to drain the fluid & pull the PTO shaft out.

Mike.........uh? you do know the PTO powers the hydraulic pump, don't you? Now ya done BUSTED sumptin inside yer tranny and guess what? You're gonna haffta split yer tractor to fixx itt. 2nd, yer 8N brush hog needs an ORC (over running coupler) otherwize when you clutch to slow down to go around the corner of the barn, litepole, creekbank, the INERTIA of the brushhog blades will continue to PUSH the tractor. 3rd, there are 2-sizes of PTO's. Original 1-1/8 and modern 1-3/8. BOTH need the 6-spline ORC. ALL modern brushhoggs use 1-3/8. Iff'n yer 8N has the original 1-1/8, you kenn gitt yer MANDATORY ORC to adapt to 1-3/8. 3rd, ya haffta "trim" BOTH the inner and outer brushhog drive shafts about 6-in ea. Hacksaws work just fine. They still gotta slide back'n'forth when done. ORC's are "pinned" to the PTO so they don't come off........HTH, Dell, yer ORC safety preacher

I would drain the oil out of the rear end
and then remove the round cover that the pto
handle is on and have a look inside.
There is a splined shaft coming out of the
transmission and the pto shaft is splined in
front. The pto handle slides a coupler that
connects the two shafts together to engage
the pto. Look around that area for something
broken. Post back with with what you find.
I would start the tractor - for a minute or
so but not longer as you will have no oil in
the transmission - to see if the shaft
coming out of the transmission is turning.
It should be turning any time the engine is
running except when the clutch is pushed
down.
It's all very simple in there so no worries
about anything popping out or coming unglued
on you.

I do have an ORC. would it take the hit before the shaft will?

 

[mike88]

I have an ORC, will it take the hit before the PTO shaft?

 

[mike88]

I know that the shft is turning because it makes a noise when I try to engage the PTO without pushing in the clutch.

 

[Bruce (VA)]

" I try to engage the PTO without pushing in the clutch. "

Why are you doing that? Of course it's going to make a noise. Push the clutch in!

Disconnect the driveshaft at the orc. Start the tractor. Push the clutch in, engage the pto, let the clutch out.

Does the shaft turn?

I wanted to see if I broke anything inside.

 

[mike88]

I haven't removed the ORC yet.. I'll do that today

 

[mike88]

the ORC does not turn after I removed the PTO shaft and the hydraulics do not work.

 

[souNdguy]

No.. the orc is a directional clutch, not a torque limiter.

If you cannot engage he clutch after you mashed the pto shaft into your tractor from it being too long, you may have lots of
expensive parts to repair as tuition into the school of hard knocks.

well, it spins freely. It doesn't turn with the motor. so you think it's a clutch. bearing, shaft? just so I know what to look for?

Bruce, it seems that you are less likely to state the obvious like "it's gonna cost a lot of money" and more likely to help me with my problem. will you please keep in touch.

Thanks

This photo shows the front end of the PTO shaft sticking out of the Hyd. Pump.

What would cause the hydraulics to stop working, if my implement shaft is too long and put a bind on the PTO shaft?

 

[mike88]

is there a sheer pin that will stop the hydraulics from working?

 

[Bruce (VA)]

Everyone is here to help.

And some may have experienced the specific problem.

Drain the fluid, take off the inspection plates & see what's in there. Get out your MPC to help with parts ID.

Look at the picture.

The shaft goes through the pump.

 

[Bruce(VA)]

No.

No.

Well I apologize, I am just frustrated. I don't know much but I do know that it will cost plenty. I just need some direction and I think it isn't going to change. I need to dig into it and see. I hope that I didn't break the pump.!?

 

[R Geiger]

eITHER THE SHAFT IS BROKE or the PTO engaging thingy is damaged! Take both side plates off and take a look.
take a look at fir 201 in the newer FO-4 service manual

 

[mike88]

thanks.. will do

The shaft broke right behind the bearing just inside the rear axel..

New shaft should cost you about $100.

$74.19 on E-bay free shipping, Thanks guys!! broke off right at the case so I could pull the shaft out with my finger tips.

 

[mike88]

I'll post pictures later.

 

[Mdparrott]

Don't forget if the shaft you're replacing is original, you'll need a new overrunning coupler to fit the new 1 3/8 shaft.

 

[Mdparrott]

Please do.

I would not rule out more damage at the PTO shifter. You will find out when you install the shaft.
Good luck

 

[mike88]

Ill look for that. but it popped at the keeper pin just inside the axle case.

 

[mike88]

just inside the bearing

Now that you have your new PTO shaft and (hopefully your new ORC
to fit the new size shaft,as others have stated) you have not
solved your problem and it's likely to happen again or you could
damage something else when you raise up your mower. The PTO shaft
to your mower should be cut on both sides so when it raises it
doesn't bind.

That did cross my mind, I looked it up on YouTube and Wil cut it down as soon as I get it all put back together. Thanks for the heads up

Sometimes it's not as simple as hacking off the ends of a shaft. If it's a telescoping shaft with an outer shaft that slides over a square shaft, the square hole in that outer shaft sometimes does not run all the way up inside that outer shaft.

Look at the picture below. Some round outer shafts have this piece welded onto the end of them. This piece is only about 6 inches long. It has the square inside hole that rides on that square inner shaft. Cut too much off of that piece and you're asking for trouble. You can take a piece of wire and bend a "L" hook on the end. Push this through the square hole and see where it catches. You will see how far your square hole goes into that outer shaft.
