I got my parts from a local Danfoss dealer. They must be fairly common as they were instock. Mine was similar i had no drive power unless i eased into it and the engine never would bog down. I have since resurfaced the valve plates one again (last year) since I was starting to have issues.
There is no bleed screw. I unhooked the outlet line and when cranking there is a little fuel flow, but not enough. if I hand pump it it fills the line. I just ordered a basic 12v fuel pump off amazon. Now Ill have to look at how to wire it so the pump runs during crank and run. Possibly a relay...
I didnt think the pressure would matter, but figured I would check. I have an inline filter that is clean. The screen on the inlet nipple of the pump is clean. Tonight i took the pump apart. Not much to it. its pretty clean but I washed it in some cleaner. The check plungers had some pitting, I...
I am noticing that recently I am most likely having a fuel pump issue. Drop in power, sometimes the rpm wont go past 50%. I cleaned the inline filter and the one on the pump, proved the fuel lines aren't plugged. Took the pump apart and found the plastic check plungers are pitted. I have also...
I just did a rebuild on mine after the charge pump failed. I also rebuilt both of the drive pump sections. The pump will come out as one unit and then it can be taken apart into the different pump sections fairly easily. My drive pumps had wear marks on the valve plates. Now I have a huge...
Nothing like having some horsepower. I keep stalling it out now. Have to get used to how it operates now. I guess the neutral was easy to find before since the pump was worn out and you had to move the sticks along ways to move. I guess ill have to fix the parking brake so the machine doesnt...
Well finally got all the proper parts and everything assembled. Total cost under $1000. Cheapest replacement was just over $3000. Full gasket/seal/oring set, and 2 new valve plates. Got the casing machined out and it was done perfectly. They took out .06" and made a cast spacer plate the same to...
A small update. I have a machine shop here cleaning up the casing of the scoring by the gerotor pump. They are going to remove some material on a lathe to make it all uniform again and then make up a spacer on the back of the housing to make up what was removed. This will move the gerotor...
I got the pump back and i'm not to worried about most of it. The 2 axial piston pumps look fine to me, no scoring. Both the end bearings are bad. One has lots of friction to rotate and one has a little play. They look standard are cheap to get. The gerotor pump looks terrible. The rotor it self...
Well it came back as something is wrong with everything. I was quoted $4000 for a replacement with 6-8 weeks delivery at the best or they rebuild mine for $4800 in a week. Found Loaderpart source has one for $1900 plus shipping both ways after core plus the great us/can exchange rate.
Im going...
Mine has a dedicated gear pump for charge flow. I dropped the pump assembly off today and got a call a few hours later that the charge pump is shot and the housing for it is also bad. Apparently the seats for the bypass valves is the housing and they worn. They are going to look into the system...
I did some testing so far. I tested the charge pressure and when cold I got 250psi and idle and 350psi at about 2000 rpm. I moved a bit of dirt to warm up the system and about 30 mins later I was loosing drive power again. Tested the charge pressure and got about 100psi on idle and 175 psi at...
I checked both steering linkages ontop of the pump and they do go full lock to lock. Ill grab some fittings and go check the pressures. Seems almost like the pump wont put out enough unless the engine is reved right up. I did a little research and it looks like there might be pressure test ports...
