Had an intermittent problem opening the grapple this morning. Hmm, what now?
At first I thought it was the control switch because the closing switch went wonky a couple years after I got the 3FV kit from Long. Just a minor issue then that it wasn’t securely fastened to the support, easy fix. I took the joystick knob apart and could feel the switch clicking when I pressed the button, so second guessed my initial diagnosis. Decided to take a peek at the valve to make sure something didn’t break the wiring and found the bottom solenoid nearly off the valve spool actuator and the plastic cap was missing. Uh oh. I decided to try to remove the top one and the whole actuator came out of the valve. Which is when I also discovered that moisture is apparently collecting inside the cap and has corroded the end of the actuator. This is starting to snowball. The corrosion shouldn’t bother the valve operation, but it did interfere with getting the solenoid back on. Sanding fixed that problem, and I think I will coat the plunger with grease to mitigate some of the corrosion problem. Popped the hoses off and loosened the bracket so I could put the valve back together. Now for the bottom spool repair. Ain’t no way I’m finding a 1” diameter cap on 2 acres after 6 hours of brush a log wrangling last week, not to mention the frog strangling turd floating gulley washer we had 2 nights ago. 3 inches of rain in 4 hours. I had some nylon spacers and plenty o-rings, but no clue what the thread was on the end of the plunger. I just happened to buy a large metric tap/die set back in February for some repairs on who remembers what, and figured the valve was probably metric. Pegged it with a 14-1.5 die. Found a little block of aluminum, bored a 1/2” hole, and tapped it to 14-1.5. Bob’s yer uncle.
Put it all back together and it works like magic.
