    Genie towable lift hydraulics question...

    An update... Updating my last posts #19 and #21... here it is 3 weeks later and I have learned a whole lot more about using this "used & abused" ex-rental towable boom lift in the last 3 weeks than in the preceding 3 months. Not all the news is good, but we finally have a reasonably safe...

    Genie towable lift hydraulics question...

    Mine is not self-leveling. Sure wish that it were. Live and learn. I am envious as Hell every time I see one of the self-leveling versions. It really is the only way to fly. The way that the manual outriggers and interlock switches work, you must not only lock the outriggers down and...

    Genie towable lift hydraulics question...

    The rest of the story... Got the new solenoid valve from Genie only to find out that it had a different size requirement for the coil... so back to my local dealer for a new coil. Fortunately for me, they had one in stock. All said and done, $156.08 and a week later, the jib boom is working...

    Genie towable lift hydraulics question...

    I agree. Visually, the valve looks fine. Brought it to a couple of hydraulics places yesterday. No one could identify it or explain its failure other than to say that sometimes these valves just simply fail. In the end, I ordered a replacement through the local Genie parts rep. None in...

    Pix of the valve in question... The jib boom solenoid valve (sans solenoid). O-rings look okay. In fact, everything *looks* okay. Dougster

    Genie towable lift hydraulics question...

    You are correct. All three booms use the exact same solenoid valve. It's pretty clear from testing so far that the other two valves are working properly. I don't see any point in messing with them at this time. I am all set to remove the faulty jib boom valve this morning and take a close...

    Genie towable lift hydraulics question...

    Correct. Lots of possibilities here. Could be the hydraulic motor itself, the relief valve (Genie calls it a relief valve vs. counterbalance for whatever reason), or the left/right solenoid valve. The manual rotate valve is definitely closed tightly, but it could even be that. This one could...

    Genie towable lift hydraulics question...

    Very little jib boom drifting down until I activate the pump (for any other function) or I manually open the drain solenoid valve at the pump. Then the jib boom moves up or down... or just down in the case of the manually-opened drain solenoid valve. Clearly, the jib solenoid valve itself is...

    Genie towable lift hydraulics question...

    My most immediate problem is that the (normally closed) solenoid valves controlling the jib boom and the turntable are leaking by. I'm assuming (until I learn otherwise) that the cartridges need to be replaced. The jib valve is sold by Genie in 4 separate pieces, but the turntable valve is...

    Be happy to. Do you just want a general picture of it or are you looking for something specific? Dougster

    Name For Small Business

    Some good ideas here so far. My thoughts: 1) Don't waste your money on the Yellow pages. No one uses them anymore. I made that mistake and got nothing out of it. On the other hand, make sure you have a top-shelf website and lots of links to it. Make sure you can be found easily via...

    Genie towable lift hydraulics question...

    Very regrettably, I bought myself a 1998-vintage Genie® towable boom-type lift, a very early Model TMZ-34/19, a couple years back. The thing was bought used and abused (and very badly butchered/horribly maintained) out of a rental place in Connecticut. Turned out to be in far worse shape than...

    Bucket Sizes for 3.5 Metric Ton Machines

    This thread is over 2 years old now and I went with the CAT buckets (see post No. 14 above) back in June of 2008. They have worked out very well as far as I am concerned, although I will still concede that some other brands do appear to be stronger. The only other bucket I have added since...

    Hydraulic Thumb question Re: Yanmar VIO35-3

    Short answer: I just don't know. I had assumed that "shut-off valves" were just that... shut-off valves. Based on what the Yanmar dealers had told me and what I read in the Yanmar literature, I had no reason to question their stated function. Now I do. Next step is to visit the area's...

    Hydraulic Thumb question Re: Yanmar VIO35-3

    Thanks guys. I think I'm confusing you a little. Heck, I am confused myself! My VIO35-3 is definitely a legitimate USA market model. No doubt about that. What I learned today is that this whole "need to add relief valves" issue that I was told about may have just been the dealers covering...

    Hydraulic Thumb question Re: Yanmar VIO35-3

    Dominion Equipment Parts was unable to help, but further dealer inquiries made this morning are starting to paint a picture that this (need to add new auxiliary circuit relief valves) may be a grey market-only issue. I'm about 75% convinced at this point, but won't be able go much further with...

    Hydraulic Thumb question Re: Yanmar VIO35-3

    Thanks very much. I will contact those folks today. The machine is a standard Yanmar VIO35-3 built for the US market. It is not a grey market machine. I am the second owner, but I have no reason to believe anything was ever modified other than for routine (busted hose, new tracks, etc.)...

    Hydraulic Thumb question Re: Yanmar VIO35-3

    Quite a while back now, I purchased a third-party hydraulic thumb for my Yanmar VIO35-3 mini-excavator. It has worked out reasonably well for a third-party stick-mounted thumb and I saved a ton of money over the dealer's TAG/Yanmar "pin-mount" hydraulic thumb. But now I have a question that no...
