Add-on forced lubrication system

An add-on forced lubrication system for a change gear transmission originally comprising a transmission housing defining an end wall and a lubricant sump, a first through bore located in the sump portion of the housing and adapted to be fitted with a removable first plug, a second through bore in the housing, a second removable plug adapted for normally sealing said second bore, a rotatable transmission shaft having an end located adjacent said end wall, a removable cover mounted to said end wall for sealing an opening provided in said end for providing access from the exterior of said housing to the end of said transmission shaft, said cover having an interface of specific configuration for interface with said end wall, said system comprising:

• a drive adapter mountable to the end of said transmission shaft for rotation therewith, said drive adapter comprising a multipiece structure clampable to the end of said transmission shaft and defining a generally cup shaped body having an annular side wall portion for clampingly engaging the end of said transmission shaft and a bottom portion, said bottom portion having a nonannular opening therein;
• a pump, said pump having a pump body with an interface substantially identical to the interface of said removable cover for mounting of said pump body to said end wall to seal said opening, said pump having a driven shaft adapted to be received in said nonannular opening in said drive adapter and to be driven thereby, said pump body further defining a pump inlet and a pump outlet;
• a first lubricant fitting adapted to be received in said first bore;
• a first lubricant conduit for providing fluid communication between said first lubricant fitting and said pump inlet;
• a second lubricant fitting adapted to be received in said second bore;
• and
• a second lubricant conduit for providing fluid communication between said pump outlet and said second lubricant fitting.
