So I've been home for a few days, and it cooled off quite a bit, so I made a little more progress on my WD project. Bought a badly-needed post-hole digger (Thanks Roger!) and had it mounted on the lift arms... it worked, but I knew the system had air bubbles in it, and it had an attitude... Well, I brought the reservoir back up, fixed a leaky fitting on an auxiliary pipe... then went to look at the linkage running that wacky valve... Took me a few minutes to figure out why it looked so goofy- the linkages crossed over eachother, and the plate-lock-together knob was nowhere near the hole... then I realized that somehow, somebody got that cam disk plate spun around 180 degrees, and it was going Major Bass-Ackward..., which is why when I moved the lever, it did some of the goofiest stuff. Now, I really haven't put deep delving into how all those links work, but after fiddling with it, I've gotten the impression that the lower lever/bellcrank (that both rods are connected to) controls the hydraulic pumping section, and the spinning cam/disk combination actually is the release valve... and depending on how the bottom link (lockout of the drawbar sensing linkage?) is moving, it raises or lowers pressure on the two valve segments. It's definately a rube-goldberg of sorts... if I were Dr. Seuss, I'd say the Gink valve heliodromically perdains against the rampet Filbrun link to frittle the axerbland quadrant, causing the pelergeb to contobulate the mitzerfram such that the mollywern stays in perpetual sphygnosis. And I may be wrong, but after fiddling with it, altering the adjustments, cleaning the pivots, tightening all the loose stuff and loosening up all the tight stuff, the darned thing actually goes up, down, and stays where I put it, and that's what I really wanted.

Well, you have many of us beat. Some of us "think" we know how to set that darned contraction, and still can't get it to stay where we want it. :-) ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |
