John Deere 727a Hydraulic Pump change

Changing my hydraulic pump on a 727a. The problem is the pump I'm replacing (p/n TCA 17484) has a shaft for the pump cooling fan; the new pump (TCA 18087) does not. Elminating the cooling fan.

I've triple checked part numbers and the old number was substitued for the new number. The new pump is made by Tuff Torq, in Japan, ;( Part number DOP10S.

Seems odd to eliminate the hydraulic cooling fan but possible. Has anybody encountered this?
