WD 45 PTO is there a slip plate or is it direct drive

It is full gear to gear but there is a shear bolt so it can break and some times sort of act like a slip clutch

It still has some power but stops under a heavy load.
 
Here is a cut from the parts catalog at agcopartsbooks.com . Check out item #38.

Probably needs a shim adjustment...take the battery box off, the curved cover underneath, and examine the shims and plates. If the shims are gone, no adjustment left, and new plates are in order. That means a tractor split. Check with I&T AC 11 for details.
 
There is a shear bolt I know because I have had to replace them in the past on the WD45 I have
 
Some one may have put in a grade 8 bolt instead of a grade 2 which would cause that
 
The transmission clutch adjustment is under the battery box. That clutch disengages the transmission leaving the pto and hydraulics "live", on the shaft ahead of that clutch. The engine clutch controls the hydraulic pump and pto. The pto is gear driven from a gear on the shaft, no clutch to adjust.

While not called a shear bolt in the parts drawing there is a bolt in the extension shaft coupling that can shear. I have seen bolts sheared and replaced them. Sometimes the bolt, sometimes the gears.

I still have a fair amount of power. I don't think I would have any with a sheared bolt.
 
Exactly what are all the symptoms are you experiencing? You said the pto stops under a heavy load. Does the tractor stop moving when the pto stops? The clutch that will slip during pto use, if you think it is a clutch on the tractor slipping, is the engine (foot pedal) clutch. How much free play do you have on the foot pedal? If the engine clutch slips the hydraulics and travel would lose power and stop as well as the pto. The hand clutch only disengages the transmission.

What impliment are you using on the pto that puts the load on it and stops? Is it just the one impliment or all pto driven implements? Do you have a slip clutch on the implement's input shaft that is slipping?

I was running a post hole digger. So I don't know if the clutch is slipping. I just know it stopped turning the auger and the engine was running.
 
Check all the shear pins good chance you broke one. EVERY post hole arguer I have seen have a shear pin and if it snaps you loose power to it
 

I am assuming it didn't just slip out of gear. Did you lift the post hole digger and it started turning again, without touching anything else? Does your post hole digger have a slip clutch on it? How does your tractor act if you try to take off in high gear? How does it act if you try to pull a heavy load? Does the engine bog down?
 
I lifted the digger and it started turning again. No slip clutch on the digger. I'll try the high gear test. I am new to this tractor so I haven't tried pulling a heavy load yet.
I'm betting it's the tractor clutch after what you said earlier.
 
Make sure there is 2 to 3 inches of "free-play" at the clutch pedal. If you look from underneath the bell housing, there should be at least 1/4" between the throw out bearing and the fingers tips on the pressure plate.
 


Without any possible doubt, it had Never been open and the AC made shoulder bolt was still in the PTO shaft..

Shucked teeth from all 3 gears and broke both upper Idler gear mounts on the lower output box..

He said it "Just when Crunch", while bushog-ing..

It had a lot of PTO hours on it..

o, it was in gear I checked that. I revved the engine and started lifting. No slip clutch. I was looking at the drive shaft and it wasn't turning. Tractor seems to accelerate well in high. I haven't tried any other heavy load.
 
If your saying the PRO shaft on the tractor is spinning then you may have shelled out the gears in the post hole auger. I loaned my post hole auger to some one and it came back with both gears shelled out In the gear box

said it wasn't spinning. I'm also trying to tighten the loose front end. If I remove the nut on the bottom of the verticle shaft is oil going to spill out? The reservoir on top is full. Is there a way to tighten the play in that area? The worm gear on top isn't moving too much so there is play down below.
 
You really need to tell the forum what you have for a front axle to get the best information. There were adjustable wide front axles, standard dual front axles, and single wheel front axles.

Don't know if you know this or not, but you can use the AGCO on line parts books to see the parts in your tractor. Go to AgcoPartsBooks.com and sign in as a guest user. Put WD45 in the search box to get to the parts book. If you don't have the operators and service manuals you should get those to help you with your repairs. Get OEM manuals, new used, or reprints first then some of the aftermarket ones if you want. This site has some manuals. AGCO has them at agcopubs.com, printed or downloads. Manuals, along with the folks here, can get you through most anything.

hank you and everyone else who responded.
 
Back to your pto issue. You said the shaft wasn't turning so you revved the engine and lifted the digger. The hydraulic pump drives from same shaft in the torque tube as the pto. Did you notice if the pto started turning, just before it lifted, when you revved it? If the shaft wasn't turning because the engine clutch was slipping, you wouldn't have had hydraulics.

What do you have for a front end? I have a manual and will take a look at it for the possible adjustments.

I noticed the pto was not turning. Then I revved the engine and lifted it about the same time and it took off.
I have a tricycle two-wheel front end. Thanks
 
If you can, duplicate the digger stopped like when you noticed the problem. Try lifting it without touching the throttle. If the engine clutch is slipping so the pto is stopped, you should not have any hydraulic function. Don't keep it in that stall condition long.

As DrAllis mentioned, how much free play does your foot clutch have? Have you had a chance to look up inside the bell housing and see what the clearance is between the throwout bearing and pressure plate fingers?

Here is a cut of your front axle from the AC manual. It only says to adjust them to a slight preload.

I hooked up a hydraulic pump to the PTO. So I'm not using the tractor hydraulics. I wanted a two-way cylinder. I left enough of the shaft to run the post hole digger.
I'll look up inside the bell housing. Thanks
