All of a sudden, the engine in my L865 will run for exactly 34 seconds after starting up in the morning and then die. No sputtering or stumbling; it runs perfectly for 34 seconds and then dies as if I shut the key off. I can immediately restart it and it starts and runs perfectly for 34 seconds...
Well, I feel pretty foolish, but I figured out the main problem. When I said early on that I had checked the relief valve, it was the boom circuit relief valve that I checked. I didn't realize that there were two relief valves until I went through the control valve drawings trying to figure out...
I was able to check the hoses from the reservoir to the pump suction and from the hydraulic oil filter to the reservoir. Both are clean and not collapsed. I spoke to the local NH service tech and he said that after all I've done, the problem most likely is in the control valve. I see that...
I'll see if I can get in to have a look at the suction hose. If I can't, or if it all looks OK, then I'm out of ideas and it'll have to to the dealer, who can do a flow test. Thanks for all the help.
I removed and disassembled the relief valve. O-rings were fine and the valve was clean as a whistle, so I bit the bullet and bought a new gear pump. I removed the old one and took it apart before installing the new one and all the internals looked fine. No substantial wear. I went ahead and...
OK, I finally had some time to try this out. I put a gage on the female coupler of the aux hydraulics. When I engage, it takes a few seconds for the gage to show pressure, then it goes up to around 1000-1500 psi. I don't have a liquid filled gauge, so it jumps areound a lot. When I release the...
I've had a problem with my boom/tilt hydraulics that has slowly been getting worse. The lift and tilt speeds have gradually gotten much slower, and if i try to lift the boom and tilt the bucket at the same time, it gets really slow. The wheel drive circuit works fine, and I've got plenty of...
The suction line connection at the bottom of the hydraulic oil tank popped off in my L865. The machine ran out of oil so now Ive got no hydraulics, but I need to raise the boom to gain access to make the repair. Anyone got any ideas on how I can do this?
Irwin, can you send me your email address? I'd like to send you a screen shot from Messicks to see if I'm looking at the right parts. Send to [email protected]. Did you fix it yourself? How big a deal was it?
That was my thought too. I took a quick look under the seat and I didn't see any obvious exposed connections between the engine and the pumps. It looks like everything is shrouded.
I was using my L865 when all of a sudden I lost all hydraulics; no forward, reverse, boom, tilt, or aux. Oil level is fine. Engine runs great but feels like it is under no load at all. I hear a faint rattling sound coming from somewhere I can't place. Any ideas?
