    bobcat 773

    Ok. I’m getting it. The Bobcat and similar setups use time for de-energizing the pull coil. Interesting.

    bobcat 773

    I think you did a great job explaining it. I wonder: When the spool reaches it’s full travel, does that cause the pull coil to de-energize? If so, if full travel is not achieved, the pull coil would never de energize. . . leading to continuous high current ( pull coil). The pull and hold...

    bobcat 773

    Ok, Willie, I just stumbled onto this one. If I understand it, the solenoid opens the fuel passage when the coil is energized. When not energized, both the spool and the mechanism return to (towards) the fuel-closed condition. Isn't the solenoid simply either energized or not energized? When...

    Bobcat fuel pick up tube repairs

    Different folks have mentioned testing the machine--running the engine with the fuel line in a temporary fuel container. That is a good confidence builder, to demonstrate the motor runs fine. But there is a crucial practical element as well: Running the machine will allow you to raise the...

    Bobcat fuel pick up tube repairs

    Hello, everyone and even Willie. Yup, another episode. In 2014 the plastic fuel pickup tube on my 2001 Bobcat 773G broke off—fell off into the tank leaving no fuel pickup tube. I have some parts records—I changed out the old plastic elbows for both the pickup and return tubes, installing...

    What's the best "older" Bobcat to buy?

    I vote for spending more up front. It is not just one thing that wears--if one or two things are "mostly" worn, so is everything else. By the time you fix this and that--parts and labor--you can sometimes buy a newer machine with fewer hours. Better to spend your time working than to...

    Replacing Hydraulic Fluid in Bobcat

    All the joking aside, we have indeed had two separate failures on the 2001 773 that effectively "drained" much of the older hydraulic oil. It's great fun changing a main drive hose out in the field. (Willie59 always works in an climate-controlled shop. :D ) While you are servicing...

    Replacing Hydraulic Fluid in Bobcat

    Hi, Paul. Welcome to HEF. I have a 2001 773 G--many common components with your T190, and several excellent threads on HEF to help you with your model. I can't resist your question. Somebody may have a better idea. What we do is get the machine stuck down in the woods or in a swampy...

    Bobcat 773: "Mystery Part"

    Surely you are not talking about the same "Slow children"? They play in your shop? You have lots of them there, too? It is a darn shame that most of us can't actually get together in person. Some of y'all are a real hoot. Crazy as my coon dogs.

    Extend-a-hoe slide lubrication

    Waxoyl "Waxoyl"? Never heard of it, so I took a quick look at the 'net. JCB apparently distributes it in some countries. For a product description, http://jcbcea.com.au/customer-support/waxoyl-rustproofing-treatment There is a USA web site, too...

    Bobcat 773: "Mystery Part"

    Don't get sidetracked trying to follow my thought process, 'traxco. I've already admitted to being daft! There ain't nobody around here with much sense, 'cept maybe for ol' Willie59. ( Around here, there are signs everywhere pointing out "Slow children" playing. Must be a lot of us.) Of...

    Repairing Bobcat Loader Float Detent

    You like the job-appropriate pliers, Willie59? Just drool! :laugh I didn't figure I could do it with slip-joint pliers. Lower skills require better tools sometimes. You could use them, you know. Whatcha got to trade? Maybe a bad glow plug or two? Burned out light bulb? I could...

    Bobcat 773: "Mystery Part"

    OK, Willie59. It is about time for you to weigh in on this one. I'm pretty much set on using anti-seize on the bolt, not red threadlocker. If it breaks again, I want to get it out. Tack-welding the head (or flange or washer, etc.) would keep the bolt tight, but would camouflage any new...

    Bobcat 773: "Mystery Part"

    Your are right, fixou812. The extra-bolt gag was indeed bad. But. . . I probably learned it from the guy I did it too. Lol.

    Related (New) Thread: Repairing Bobcat Loader Float Detent I have finally paid a tiny portion of my debt to Willie59 by . . . staying up til 2:15am and posting the year-and-a-half old images of the float detent repair procedures. See the new thread, "Repairing Bobcat Loader Float Detent"...

    Repairing Bobcat Loader Float Detent

    Float detent assembly completed! That's it! Done! Follow Willie59's instructions in the "Replacing Bobcat loader control valve seals" thread to reassemble the spools to the valve body. Again, be absolutely sure to buy extra detent springs and balls. They are cheap. We lost one--only...

    Repairing Bobcat Loader Float Detent

    Apply some assembly grease to the indentions in the pliers and to the new detent balls. Position the balls in the dimples in the pliers. The grease will hold the balls in place in the pliers. Image 4449 Hold the collar back and insert the new spring into the "lower" hole...
