Hi i am working on s185 after a short while the tilt will start to roll back {only| by it self and the lift seems to jerk while going up. also if you lower boom slowly almost stopping ,and tilt back at the same time the boom will go up.pulled anti cave valve and did not see anything wrong .maybe a cracked valve ?
 
A crack is possible, but i wouldn't have expected it to jerk as it moved.
Its possible its a load check issue too. I'm not sure if they are fitted to the newer machines or not. They are on either end of the control block on each section. From what i understand, they hold the pressure there while you operate the controls to prevent the ram dropping.
I'm just guessing here.

hi Tazza I checked the load check valves seem to be ok. I think I have an issue with the tilt actuator that I in stalled earlier. I believe it needs to be programed with a lap top by the dealerw Will find out fpr sure.Thanks for the help also

Its possible, but if its new enough, some just need calibrating, the procedure should be in your manual?
