NH Workmaster PTO Question

[Qapla]

We have a NH Workmaster 45 2W Gear Drive that makes a slight noise when the PTO is engaged. 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

I've got a Workmaster 33 with 130 hours on it. Without going and getting my manual, when are you supposed to change the oil in the rear end? Five years seems like a long time, but I don't know what the manual says on maintenance for that. Mine is geared also and I've enjoyed it so far.

I would change the oil in the rear end/ tranny (probably common sump) now if there's a noise. And I would use the recommended fluid. The 90 would probably just be too thick IMO unless you never are using it below 30 degrees.
