Got a 4440 quad range tractor I just replace the pump on due to a leak. Put a new pump for ASAP on it. Not for sure if the problem was there before hand but customer now has an issue on with the pressure line pulsing, can also feel it getting hot. The pressure and return lines have been Teed off for remote valve for loader, one line comes off of the SCV and the other line is teed off on right side of tractor. Don't think the issue was going on before pump was changed. The line going to the SCV is pulsing pretty consistently and getting hot. Just curious as to what I should check before I condemn the new pump or how to confirm the new pump isn't bad? You can pretty much feel the pulsing thoughout the whole system. I changed the fluid and filters, but didn't check the T/M pump screen when oil was out. Do I have a supply oil issue? Just kind of weird that this problem came about after replacing pump.
