01 bobcat 753 lifts half of what it should

[Dbrider456]

Hey guys, so my machine sprung a leak at the hydraulic control valve, ends up a bolt on the end of the lift spool valve broke and caused the leak, the valve ended up needing to be replaced which I did on my own. Everything worked perfectly for about 20 hours. Then all of a sudden while moving a log Pile it would want to lift nearly as much as usual. The machine can still be used but I can only load the bucket half way with dirt, any more and the arms won't go past a certain point. When I bought the new valve it came with a bics that wasn't the same as the old so I swapped with new o rings. Is that something that could cause my issue? All lights on, no codes, machine works as it should just doesn't have the capacity, and I have not tried a pressure test yet. Any help would greatly be appreciated. Thanks

Have you checked your relief valve pressure setting? Seems odd the it would suddenly change, but it is something to start with. You will need a 3000 psi minimum pressure gauge that you can connect to one of your auxiliary connections to check it. HTH - SR

I'll try that then I'll get back to you.. May be a few days trying to find a gauge
