ok, have a 10042, will not extend all the way out, on the intermediate boom, there are letters. Typically it will extend out past "G", right now it won't show the letter "F". The wear pads are a little out of spec as being worn. There is a hammering sound after retracting, at the time of extending, but it is quick. Limiters appear to be working as I've disconnected and reconnected. Chain tension is about right. Could it be air in the cylinder? Any ideas would be helpful Thanks Ian
Stand on a 4' stepladder and Remove the rear boom cover. Shine a flashlight inside while the boom is extending and retracting. It should reveal where your noise and bind points are. Have the S/N of the machine and call Steve @ 734-516-5675 to discuss the problem and solve it.
Thanks after messing with this for countless hours I found that it is a hydraulic issue. The check valve is cracked. New one on the way. Not sure how it would get that way but wonders never cease!
which check valve failed?
The "block", Eaton Vickers MCD 7280 .... the aluminum block had a hairline crack in it where the actual valve screws into it. How that happened, nobody knows.... the valve screws into a milled solid piece of aluminum.
