John Deere 620 power steering

FarmallJC · May 10, 2016

Hi, I'm going to have to replace the power steering pump on my 620. The primary radiator hose is solid metal and the water pump bypass hose is pressed in. How do I account for them when trying to move radiator forward to take fan out?
Thanks.

no need to move the radiator. if you take out the 2 bolts that hold the pump to fan shaft and slide pump forward ( after unhooking lines and removing
the 2 bolts under pump that hold it to the support) you can take a 2" cut off wheel on a die grinder or some tool of the sorts and cut a notch in fan
shaft tube on the left side in front of where the pump bolts to it (there is about 1/4" to 1/2" of tube sticking out in front of the casting). with
the air cleaner off the pump will come right out the left side then, fan and all. or if the book says to take pump out the right side make your notch
on that side then. I don't remember what side the book says to take pump out of, i just know i came across one that this had been done to and i know
it was on the left side

The steel coolant lines seal in place with "O" rings and can (with difficulty) be pulled out.

It MAY be possible to sneak the pump out of there as the other poster says, but BE CAREFUL not to bang up the radiator. I cleaned up a mess and repaired the radiator on a 720 some years ago where the previous "wrench" had tried and failed to get the pump out of there by means of the old "cut a notch in the tube" plan.

It is easier to move stuff out of the way than to damage things.
