PTO Lubrication

[Old Tow]

Where does the PTO box receive it's lubrication from? I it like the rear differential in that you pull a plug and fill it, or does the tranny fluid lubricate it??

 

Thanks in advance for any and all answers !

Depending on application.  When mounted on manual transmissions, essentially, the PTO becomes part of transmission case.  Gravity & centrifugal pressure.

Mounted on a automatic requires a hose attached to pressurized port on trans & return is gravity 

Only required service is lubricating the PTO pump splines & NOT-leaving it on driving

Thanks for the answer. I failed to mention it is on.  A 2000, International, roll back with an automatic tranny

Yes, That ahould have the trans cooler lines plumbed through it for lubrication. The input gear of the P.T.O or flywheel as it is sometimes called gets lubed via the rotation of the trans gearsets.
