L 555 hydro problem

[Freight260]

hi everyone. My 555 deluxe is giving me trouble. It sat for a while and when i went to use it, the bucket wouldnt lift or curl. A little not much so i cleaned the pre screen out ( it was filled all kinds of juck and silacone). Everything started working fine for about 5 mins and then the lift and curl started to slow down back where it was before. So i changed the filters and checked that pre screen again and it started workin fine again for about the same time again and now we are rite back to square one again. i havent had the machine for long so i would love to use it before the newness wears off. thanks in advance any advise is greatly appreciated.

Yeah, when I got my first got my L555, I had the same problems. If you saw a lotta junk on the prescreen, chances are some stuff made it to the pumps and valve body. Keep cleaning out the prescreen and working the machine. You might get all the crap worked out. You may have to change out the hydraulic fluid, it may be so contaminated that it just wont work. Another possibility is the valve body. If some junk made it into the valve it could be restricting flow. To access it, you have to pull the skid pans and fuel tank, it's a booger of a job but might be neccessary. Keep cleaning and working, it's a tough little skid steer and can take a world of abuse. By the way, I have found that most of the contamination comes from the drive chain adjustment bracket. Most people don't seal off the bracket with silicone which allows water and dirt into the chain cases and then the hydraulic system.
