Workmaster 45 PTO question

[Qapla]

We have a Workmaster that makes a slight noise when the PTO is ungaged. The noise is not very loud and almost sounds like a slight "whistle". It only makes the sound when the PTO is engaged and even then, more so when it is under load then just engaging it to listen for the noise.

We had a friend listen to the noise. This friend works at the local Ag-Pro Dealership as a tractor mechanic. He told us to try something we wanted advise on:

He said to drain the transmission fluid from the rear end and take the old filter off. He told us to replace the oil with 90 WT gear oil and a new filter. He said that should solve the problem for quite a while and we would not need to replace the bearing, at this time.

I should mention that the tractor is five years old and the oil in the rear end has never been changed.

What do you think?

I guess a second question would be - how difficult would it be to change the output shaft bearing?

Thanks for any help you can offer

He is either a very old school mechanic that doesn’t understand modern tractors or he is an idiot. Don’t do it unless you want hydraulic system problems.

Still waiting/looking for some input/comments/sugestions/answers

How has it been determined that the output shaft bearing (of which there are two) is the source of the noise?

 

[Qapla]

The output shaft appears to be #6 and the diagram only shows one bearing (#8) although there are two additional bearings (#2 and #4) on the PTO shaft (#3)

Would all these bearings need to be replaced?

We have not removed the PTO to do a visible inspection. Is there any other way to determine if the bearing(s) are the culprit?

 

[RickB]

The output shaft is reference #3 and is supported by bearings #2 and #4. There is no way to know if or which of these bearings is failing without disassembly.
