Same flows? little confused, when I looked at tractordata.com, you can find the NH Boomer 4060 has a main hydraulic pump that flows 12gpm using a tuned up (more HP same engine as LS XR4046) Shibarua N844 and power steering pump that supplies 5.5gpm. The LS XR4046 has a main hydraulic pump that flows almost (manual says 7.6 GPM) LISTED 8gpm and a 4gpm power steering pump. I then looked at both pumps and the bolt pattern PLUS the shaft were the same (10T splined shaft). The only differences is where the hard lines (input and output) for the pump are, on the 8gpm the input (suction) is just a threaded hole so the hard line won't work, will have to be removed and using some adaptors change it over to a hydraulic rubber hose supply line. Then for the output (pressure) side, I think the pump is LARGER and it puts the output farther back (I could be wrong on this) and it won't match up to the hard line and then this might also need to have some adapters and converted to a high pressure hydraulic rubber hose. This is all in theory, I don't have the pump yet and Im pretty sure the hard lines can be removed and adapters such as BSPP etc. used on the other ends.Pity NH didn't do the same thing when LS switched to the LS Mtron engine. Same flows from what I see.
