Check sequence valve in control valve. There should be a total of 3. 1 -⅛ or 1-¹/¹⁶ plugs on the top and bottom of the valve. 2 for bucket, 1 for boom. I think the F series had all 4. Anyway, the valve should come out with the cap. Based on your description, I'll bet they're stuck in the valve. Make sure to block up your boom and bucket safely and that there is zero chance of it crashing down, when you pull the valves, you will get tank oil. So have a vacuum on the tank or drain into a storage vessel. Good luck, safety, safety, safety. Please be extremely careful.

Hello everyone, I removed these 4 plugs the little spool works well on the 4 and I noticed when we turn the steering it hits like a little hydraulic hits

What are your cycle times ? Raising the boom off the ground to end of travel should be no more than 5.5 to 6 seconds

Pump 1 has likely crapped the bed. Pump 1 is work only, pump 2 is steering and work. Pump 3 is brake and fan. Is your steering ok?

Im guessing that those are the pumps dying efforts. I would advise no more work, you're just spreading shrapnel

I also noticed a fuel code 96-0 or-1 I will check the - . which occurs and fall into protection mode I have done several tests fast idle idle or while driving in the street a good mile and this code only occurs when I touch the working hydraulics or if I steer the engine idling fuel release my reasoning is that seeing that the engine drops below 500 rpm the feed pump does not provide the request I think except that if the hydraulic makes a request the engine should increase the rpm? this machine is the devil you remember me the shaft of the first and second gear breaking in December yep the same again lol my L60f is a good one but the L70g lol So I'm going to do pressure test and inspect my hydraulic filter and give u news soon Thanks for your time

The pump on the left, closest to trans is hurt. I'd be more concerned with that. Get your hydraulics square then run after engine issues.

The play is more easy to move on the Fuel pump trans side

Ok. Sorry, thinking of larger platform 110/120
60,70&90 have pump 2 under cab, pump 3 on engine. With such a slow cycle time, i would guess that the pump under the cab is hurt badly. Check your filter for debris. See if you've got packing material or worse, brass and iron.

Cycle time for boom raise should be about 5.5-6 seconds

I opened the fuel system because I had this code 96-1 and I heard a cliking noise coming from one of the 2 pumps I closed each injector one by one with the computer the noise has always continued so I do not believe that it comes from an injector now I have to reassemble everything I will open the hydraulic filter I think I have several problems in one Thanks for ur help again
