Teagle topper problem

[shepherdess]

I'll pm you

 

[ced]

try some synthetic gear oil in the gearbox. should run a lot cooler if gearbox is set up correctly

 

[Mursal]

Hopefully all is now sorted, or will be shortly.
But whats the plan of attack it the new one goes hot, have you everything in place to totally loose the plot in front of the Teagle boys?

@shepherdess
I'd still be inclined to get a second opinion on the pto shaft setup (not from teagle though). If it goes bang again with a new gearbox then teagle understandably won't want to know.

Not suggesting you're doing something wrong but a different pair of eyes might spot something different. Doesn't need to be an engineer. Just an experienced tractor driver should know what they're looking at

 

[Mursal]

I really cant see how the heat is causing the shaft to fail, but am willing to learn

 

[shepherdess]

Will do, got another/different dealership in area will get them to look then.
Nor can I mural but I'm no machanic, it's just what I was told by one of them, that the Greese heats then breaks down and weares the bearings till they go bang, just relaying what I'm told

 

[Mursal]

Not trying to be difficult ...............
But I never heard of the grease completely melting from a shaft joint, leaving it dry enough to fail.
Just maybe something we have not come across before, anythings possible.
So if we go with that explanation, if you greased the shaft more the shaft wouldn't have failed? How many hours would it roughly take for one to fail?

 

[shepherdess]

That's what we had started doing, greasing it every 4 hours or so, pita.

I'm not implying it is what caused them to go, just what I got told was a likely possibility causing it? The shaft connected to gear box was flipping hot too would make yellow pto guards black souround go like paper

 

[shepherdess]

Hard to say on time it took, each time was different circumstance, first few we weren't greesing ot more than you could normally. Guess they were looking to cover all possibilitys first? No idea? Sometimes it would break one before it was that warm after not doing much but more often when been going few hours

 

[Mursal]

Said it to the brother today (bit more experience than me), just in case we were missing something ..............
He mentioned when stopping is the free wheeling clutch letting it run on when the tractor stops the shaft?
But I'm sure it is ......
Hopefully the new gearbox will do the job

 

[shepherdess]

Yeah it runs on for a short time after stopping pto I did try and upload a vid of it running up then down but would load it sadly

 

[Mursal]

I think you have to put in on U-Tube then post the link ...........
If its not one thing its another ...............

 

[shepherdess]

Ah that proberbly why then, though pic takes a few mins to load on my snail band so gathered as it was bit bigger file it couldn't cope

 

[General-Lee]

You can link from Facebook.

Even running at full power constant would not cause the shaft yokes to heat up,
unless, the alignment was wrong.
shaft too long and bottoming out at some point of drop or lift
shaft not sliding freely

 

[Pheasant Surprise]

Let's just hope @shepherdess for your sanity the new gearbox has cured it. Give it a good proper run!

 

[shepherdess]

Cheers but I Don't use face book.

Shaft did have to be pulled out a fair way to reach tractor, though they fitted it for us to cut to size,

Thanks pheasant surprise and will do, still plenty to do so will get a good testing

 

[Richard Devon]

just one other thing......do the yokes at either end line up correctly?....as in both vertical, not slightly out of timing

 

[Grassman]

If you were nearer I would call and have a look myself!
I have known some dairy farmers (no offense meant to all dairy farmers!) who don't know what a grease gun is and wouldn't have all the grief you have had with this topper!
As @Mursal says I have never heard of heat doing this damage to a pto shaft.
If it is somehow melting the grease then it may be an idea to use high melting point grease however It's just not right for a gearbox to run that hot.

Just picked up a new Teagle PTO from dealer that looks heavier than the original one have lowered roller to alter angles(advised by visiting technician) so we'll see what happens no offer of new gearbox here
