Check the parts section of the JD web site. One never knows if something was changed or not.
If the pumps are the identical size/model, then they should swap.
What are the hydraulic problem(s)?
Some caution however.Probably 95% of "front pump problems" have either nothing to do with the front pump. It's either a failure of oil supply TO the front pump inlet. Or it's a relatively quick, cheap and minor job to swap out the front pump stroke control valve assembly.Worn drive shaft couplers on occasion too.
We see people here all the time tearing into front pumps and later after spending much time and $$$. Having the hydraulics operate no better than before.

According to JDparts.com they're the same pumps if both tractors are 2WD.
