Yes you can I had my block bored this spring. I know a JD4850 block is 3.750" and I bored my block to 4.200" Hope this helps Brandon |

Just have the pump shop machine the front hub of the pump down to the same diminsions of an a pump. The o-ring that seals will no longer work just use silicone instead. This is what I did becouse my engine was together also. And the cost was $150.00. It works great. |

That sure would be a lot easier. How long have you ran this way ? Is there much machined off ? Thanks |

not gonna work
|
u cant have a 7100 pump machined down to an A pump size. U can only machine it down to a 3000 p pump |

My bad our pump is a p-3000 not a 7100. Is there a differance in the hub from a p-3000 to a 7100. |
Re: 7100 on JD 4440

actually, no. A true P3000 uses the larger pilot diameter, and 30MM cam like a P7100. Standard old P pumps like on an 8640 ETC are not P3000's technically. People have started referring to all the standard P pumps as 3000 to differentiate them from the 7100, & 8500. |
