Hi Folks,
I've got a 52 8 that i've been working on for a little bit here. I'm afraid to say i'm at my wits end with regard to the Hydraulic adjustments. The situation is such that when I hook up my sickle bar mower, if I start the raise the implement up to travel, once it comes up a little it goes all the way up. Then when I try to slowly lower it, it just drops all of a sudden, slamming the implement on the ground. I have found that it appears that when the implement is coming up, it is pushing the spring and thus the draft control plunger in and taking the linkage out of adjustment?? If i adjust the top link bar such that it is a little looser when lifted I can regain adjustment control again, but at the cost of making the mower go out of ideal setup. IE the sickle bar is not lifting high enough etc.
I have spent the last month or so researching this site and others looking to get as educated as possible. I have removed the top plate and cleaned and lubricated all the linkages and pump housing and changed hydraulic fluid. I have replaced gaskets and replaced the piston to a jubilee style piston with new o-ring and leather wiper. I have flattened the spring plate and checked the control arm for straightness.
Additionally, I tried to follow the directions in the direction in the original Ford manual to adjust the spring length and dimensions but to no avail. I even tried to find "Zane's Jig" but was unable to find the Jig nor Zane.
The piston does not leak down when the arms are up with clutch depressed or PTO disengaged. It seems as if i just can't get the adjustments correct, and I'm looking for any education or assistance you all may provide. Thanks so much in advance for the help!
thanks,
