    Case CX14 low/no hydraulic power

    The set screw/spring are what controls when the pump destrokes, right?

    Case CX14 low/no hydraulic power

    So the Case dealer was partially helpful and could get some of the parts within a couple days and the rest being 30 days out. The Kobelco dealer ended up finding a pump rebuild kit in stock at a dealer in Texas, so they had it shipped. I rebuilt the pump and got it installed. Magically when...

    Case CX14 low/no hydraulic power

    Well my brother did try to use it one day when we did have a fair amount of snow and seemed to be about the start of the issue. You might not be a pump expert, but are surely close enough! So the thin metal plate (part #6) should be up around the feet and swivel on part #4? I was wondering...

    Case CX14 low/no hydraulic power

    If those are what the pistons look like new, than I'm sure they are just about wore out. Photobucket is blocked at work and I some how blew up my phone last night, but I'll look closer and take some new photos tonight of the pistons and the swash plate. I lined up the 3 pins and they all...

    Case CX14 low/no hydraulic power

    I have that part and the spline in it look fine too. Just didn't get a photo of it, but it looks identical to the piece in the bottom photo you added.

    Case CX14 low/no hydraulic power

    So I've finally gotten a chance to pull the pump and I've taken it apart. I see absolutely nothing that resembles damage/scoring to the internals of the pump and the splines look perfect. I took some photos and uploaded to photobucket, there are more than these two, but I'm struggling with...

    Case CX14 low/no hydraulic power

    That makes a little more sense. So with the flow meter in line, it measured about 1 GPM at low or high throttle. I closed the load valve a few turns but the pressure didn't move, but I was hesitant to turn it too far. When you say maximum angle is that more perpendicular to the shaft or less...

    Case CX14 low/no hydraulic power

    When I put the flowmeter in the P2 (I believe, or could have been P3) there was very little flow but no pressure. If I understand you correctly there should have been about 2,500 psi?

    Case CX14 low/no hydraulic power

    lantraxco I sent you an email. From the shop manual mine appears to have the same pump or at least the same style. It doesn't make any noise, unless you are trying to use some function. I didn't know their was a bleed plug.

    Case CX14 low/no hydraulic power

    I believe there are only 4 lines to/from the pump and no electrical wires. There is the suction line from the tank, pilot output line and 2 main lines. I want to say there is an internal pilot passage in the pump (there are 2 dashed lines in the schematic from the P3 (pilot) to the P1 & P2...

    Case CX14 low/no hydraulic power

    Sadly we haven't gotten this resolved. A mechanic down the street was supposed to be coming to look at it, but hasn't ever showed up yet. I'm curious, since you've had the pump out, what is the connection between the pump and motor (i.e. splined shaft with a key, a coupler, etc.)? I've asked...

    Kobelco hydraulic excavators

    I'm having trouble diagnosing an issue with a 2004 Case CX-14. I'm not sure who is the actual manufacturer being as the service manual also applies to a Kobelco SK13SR. It has Kawasaki pilot valve body and a 3-cylinder Yanmar engine. I've posted looking for help with a hydraulic issue but...

    Case CX14 low/no hydraulic power

    So I was able to spend more time on the excavator this weekend. I'm still at a loss of what's wrong with it. I checked the voltage at the two solenoids at the pilot control valves. Both get 12 volts and click with the level locks engaged. Removed the relief valve at the pilot valves and it...

    Case CX14 low/no hydraulic power

    Hello all, I'm in need of some help from the experts on this forum. My brother has a 2004ish? Case CX 14 mini which has sat pretty much unused over the winter and when he went to use it the other day it has barely any hydraulic power. We have a repair manual, but I'm not very familiar with...
