JD 790 Injector Pump Removal

[handloader]

Need to bring my pump to injector shop for repair. Shop said they are not difficult to remove. Easy for him to say. I have all lines and bolts removed that I can see but something is still holding it to the block. Took cover off front of oil filler tank that houses gear etc. There is a bolt on the front of the shaft with a keyway according to the exploded view but it won't budge. Anyone have a Service Manual that can help me get this thing off and to the shop.
Thanks,
Gary
