Ventilator pump parts

I'm in the process of rebuilding the ventilator pump and fan on my 51 model A , it was pumping oil up the
shaft and coming out around the fan. I found most of the parts needed from J D or aftermarket. I was told
the 2 springs in the pump were probably broken well they were still intact, but I would like to replace
them anyway but the J D dealer says they are not in stock anymore. I was wondering if anyone here has
found any that would work, I'd like to know where

So what DID you find wrong that was causing the oil to move forward and leak at the fan?

As to the springs, www.mcmaster.com has a wide selection of springs listed by dimension.
 
I really can't say, unless the springs are to weak or the eccentric is so worn that the springs are too
short now. The felt seals behind the fan were worn out but the way I understand it they just keep out
dirt and keep grease in. Oil should not be up there anyway.
 
Found out that I had gotten the wrong information on the springs. I looked them up online myself and they are still available, just waiting for them to come in. Thanks to those who offered help.
