I believe my hydraulic pump is on it's way out, the last owner said it takes a little while to warm up, and I've definitely noticed this. I've put 5 gallons of R&O hydraulic fluid into the tank that doubles as the left loader arm pillar but I'm not sure if I should top it off or not, by the sound it makes when filling it it is now very close to the top, yet it has not solved the issue.
All of the hydraulics act like there is air in the system for 10-15 minutes after firing it up, lifting the loader arms, curling the bucket, and turning the steering wheel during this time both make the pump create quite a bit of noise and the hydraulics work jerky and sporadic (timed with the noise) until the system "warms up" and it will run fine for the rest of the day.
Does this sound like air in the system? or would it be cavitation? Do you guys think my pump is making it's last death wails? It has been a few years since I took a hydraulic class but they only explained cavitation as "Turning your steering wheel in your car all the way to one side until it squeels" It kinda sounds like that.. but so much different/worse..
Thanks
