    Foam filled tires going flat

    Thanks for this great information everyone! The valve stems were full of goo, and I was unable to remove the center pin. But I think I now may know one reason why these tires look more flat. I had the machine parked parallel on the side of about a 15 degree incline Hillside and when I looked at...

    Foam filled tires going flat

    I have a recently purchased 2004 snorkel tb60 manlift 22000 lb 4 wheel Drive with 4000 hours on it. Two of the four originally Factory foam filled tires look like an air filled tire that is halfway inflated. So I'm wondering if the foam can deteriorate inside, and if so is there a way to add...

    So would blue Loctite 242 be a good choice for that Allen screw seat? And I'm wondering would it be resistant to Dexron II transmission fluid, which is what this machine has for hydraulic oil?

    Thank you, that makes perfect sense!

    Yes TVA, that is right, and that would be a 3/16 inch ball. But I'm curious, what would prevent that ball from blocking the other common outlet for that shuttle valve?

    Okay, so the ball bearing cannot be larger than 1/4 inch in order for it to drop down the cavity, but it must be larger than 5/32 so it does not come back through that retainer bushing that I photographed last night and posted. So I would say 3/16 or 7/32 inch ball bearing? Which would you suggest?

    Thanks TVA. Actually I completely bypassed the counterbalance valves and the drive brake manifold, and you can see this in the picture if you zoom up and follow the forward drive hose connections. But I did not plumb the parking brake needle valve into that direct line, because I just wanted to...

    Well, I discovered that there was an allen screw retainer in that shuttle valve, but instead of there being a ball on the other side, there was what looked like a bushing and tiny washer, see picture below. So when I plugged that channel, it stopped the leakage between the two Inlet ports and...

    I understand what you're saying about drilling and plugging the passage between the two Inlet ports inside the block, but wondering if you could diagram the tees and where those lines would go?

    Not sure what you mean by Cross Point? And by needle valve do you mean that parking brake T fitting that screws into the top of the valve block pictured? And if so, I don't see how that could cause leakage, unless there was a leak inside the parking brake or brakes? But then again, I did have...

    Any way to get a manufacturers diagram and or part list on this block that is better then what I already posted from the marklift service manual?

    you mean missing ball, not block, right?

    The schematic diagram would indicate a steel ball in the shuttle valve, but there was no steel ball in my shuttle valve, just a small 16th of an inch drilled hole connecting the two Inlet ports and the shift cylinder and parking brake circuits. I don't see where you gave instructions on checking...

    I don't know if it bypasses or restricts. Since I have one of the outlets on the pressure gauge and capped off, and the other three Outlets capped off, I'm wondering if it's possible that part of the hydraulic flow is going back through one of the two Inlet beefy hoses that is not engaged? And...

    So I reconnected the drive brake valve block to the 2 in coming forward and reverse big beefy hoses and did a pressure check on each of the 4 exit beefy lines, and each one measured at 1200 lb instead of the 2400 lb at the incoming lines. ( I tried to upload an MP4 video but apparently the Forum...

    No they are not in the same cavity, they are in separate cavities. Each one is in a cavity for each dynamic Drive brake counterbalance valve.

    So I may have to reverse the sleeves over the Pistons in the counterbalance valves in the attached picture? I can't remember which direction they were when I took them out LOL I suspect the top one in each picture is the more correct configuration since if it was the other way, part of the...

    So when the return line goes through the proportional directional control valve, I assume that the return line is one of the big beefy lines either forward or reverse line?
