I got the power beyond fitting from Mark at C & C this week. After much fumbling on my part (don't ask) I finally got everything installed. This was my first experience with hydraulics.
2 problems, 1 small, 1 may be large:
The top cylinder makes a "chattering" noise as it extends when it has the weight of a 6' straight blade on it. No chattering when I tested it without anything hooked to it. My best guess is the check valve is cycling rapidly, like 100 times per second. Cylinder extends OK, just noisy. No noise when retracting. I have cycled a lot of times thinking maybe it had air in it but no change.
The second, and more worrisome problem, is the tilt cylinder appears to be about 2" too long for the B7510. With the straight link between upper and lower 3PH arms on the left side (normal position) and the cylinder fully retracted, the left side of the 6' blade is no more than 1 1/2" lower than the right side. When I extend the cylinder the right end of the blade is all the way down on the ground before the cylinder is even fully extended.
I changed the left link to the adjustable link that was originally on the right side and have it extended as far as it will go and the left end of the blade is still only about 3" or 4" lower than the right end. If I extend the tilt cylinder the right end still hits the ground.
It appears to me that I need either a shorter cylinder for the tilt.
The end shafts on the cylinder screw into the cylinder and I have them screwed in as far as they will go (cylinder as short as possible). I even cleaned up some welding splatter on the threads so I could screw the ends all the way in so there is no more adjustment available there.
I also have the pin on the bottom 'fork' in the upper hole and in the hole furthest from the tractor on the lower 3PH arm so that I have the shortest linkage possible. There is no room to drill a hole in the 'fork' nearer the cylinder to shorten it.
Anyone who has top n tilt on a B7510 or B7610 had that problem? If not, could you possibly measure your tilt cylinder for me?
I will call Mark Monday and see what he says but I noticed he only shows 1 tilt cylinder on his website so he may not have a shorter cylinder available.
Sorry for the long post but I am trying to give as much detail as possible.
This may all be easy to fix when I talk to Mark Monday so don't think I am saying anything negative about him or his company.
