Hi All, I have a 1986 JLG 40HT. I am looking for a square solenoid for the vickers type prop valve block. The original square solenoids are obsolete, and the superseded parts are also obsolete. Looking for leads on a salvager in the US or some other JLG parts wizard who could advise. The Google magic is a big disappointment when trying to find these parts.
Did you try removing it cleaning and bench test it? Sometimes you can get them working again
Got off the phone with JLG, and got some equivalent Vickers Part numbers: 689610 Solenoid Coil [7009315 (coil and frame, round) has been superseded by Item 7020361 (KIT, COIL 12V FLYING LEAD), OBSOLETE] 7009360 (Adaptor Kit, OBSOLETE) contained the following Vickers part numbers: 686035 core tube (JLG 7009316, available, $302) 680914 nut, retaining (JLG 7009317, OBSOLETE) 924070 adapter plate (OBSOLETE) 513771 pin (JLG 7009319, available, $15) So it looks like I am on to Eaton - Vickers.
Hi Moon, I did put it on the bench and cycled 3 or so times with 12V and it worked. I ended up swapping the coil on the boom lower prop valve and that proved it was something with the solenoid and not controls or hydraulics. I've got a troubleshooting thread here HeavyEquipmentForums I'm definitely open to any other suggestions. if I can even find all the parts I'm looking at $7-800 to replace the obsolete parts with more obsolete parts that might at lest be available. in the meantime, I am getting one of my kids to operate the emergency valves to let me down. Cheers!
just went and messed with it some more. ohmed at 6 ohms. put a meter on the coil lead and could read 13 VDC. put meter inline to measure amp draw and got no amps. reconnected, now it works. ghost in the machine I guess.
