I pulled my main hydraulic pump the other day, and it is stamped with the numbers 389114R92. I do not find this on any resources I have, and i just wanted to make sure I can replace it with a model number 70933c91 pump. It appears that all the new aftermarket pumps have an extra port on the face that attaches to the spacer that the original does not have. any thoughts? Thanks for helping a rookie!

Boy, I dunno Danny. Ya don't sound like a rookie to me. :>)

Your working on the back "hitch/remote" pump right? Back in the rear end?

Your 70933C1 is the 12 gallon per minute pump. Converts to the 70933 aftermarket number. Should bolt right in there and yes, they all have that little extra "hole" (think the darned thing dead-heads anyway, doesn't it?).

Now, the only thing I would suggest is that if you ever are going to be using this tractor on a loader, a big 12 row planter or the like, that 12 gpm makes for kinda "slow" operation and you might want to consider the bigger 17 gpm pump.

Otherwise, be sure you get the o-ring and gasket seated and it's gonna be just fine.
