ABSTRACT:
A lubrication system is for a power take off assembly and a drive shaft therefor. The drive shaft is mounted for rotation within a housing having a lubricating oil sump and is hollow to include lubricating supply passages therein. The power take off assembly includes a casing sealingly secured to the housing about an opening which provides access to the open end of the hollow drive shaft. Within the casing is a take off shaft which is coaxially aligned with the drive shaft and a device for selectively coupling the take off shaft to the drive shaft. The lubrication system includes a pump which is driven by a gear rigidly secured to the end of the drive shaft and provides lubricating oil from the sump to the end of the power take off assembly casing remote from the housing. Lubricating oil passes through the interior of the power take off casing to the end of the drive shaft to provide lubricating oil therefor.
