i installed new aftermarket pumps on this deere 330clc and was curious if people know they are set close from factory as the little center screw on max flow is way out from the 3/16" book calls for but who know if that is same on these "china" pumps doing track speed test came up even between the two sides but is slow book calls for 27-31 seconds for 3 revolutions and this was right at 43.5 seconds on both.. little nervous to set these pumps..but going mark excatly what do and see if can improve it has anyone ever set these pumps "hitachi style pump" and knows first hand if they follow same measurement for screw 4 and 5 ??

    I would do an arm in over relief and check engine pulldown if it is in spec i thank you will be ok.

    And check pressure on monitor I’m guessing?

    Would be good to do. Was there a considerable savings with aftermarket pumps?

    Stick out cycle time is a good one to check too. Should be around 3.0 to 3.5 seconds engine pulling down to approx 2000 rpm.
