    Champion 740 wheel stuck on hub

    I'm now thinking the chain could have come off the sprocket and be riding on the hub beside it.Not sure if that's even possible but the symptoms fit.Will pull a cover off and see.

    Smooth transition from flat to slope

    I think its called blade sense or skill or practice.Tickle the levers.If you find a magic answer let me know. Some operators just seem to have it,others not so much.

    Champion 740 wheel stuck on hub

    I think so. looking at parts book the double sprocket appears to be welded. Im hoping the weld might have let go. Anyhow i think this is an old issue i can notice the rear tire is more scuffed up and worn than front one. Think ill run it as is for awhile It grades fine.

    Champion 740 wheel stuck on hub

    Well I got it off finally. I deflated the tire too much and it lost its bead seal..Tire had fluid in it. No way could I get it to reseal so I dismounted it... I think either the fluid or the o ring may have been the reason It wouldn't reseal. Used bead blaster which has worked for me in the past...

    Champion 740 wheel stuck on hub

    Trying to remove a wheel and tire. Well and truly stuck.All nuts and wedges are off,put a 3 to portapower from frame to rim,no go.Myremaining ideas are to put a piece of 2 inch pipe between chain box and rim,at a slight angle ,then rotate wheel with drivetrain power. Or put nuts and wedges back...

    Driving piles with a 15 ton excavator and rock hammer.

    Thanks that's the stuff I needed. Have a second excavator available so that should not be a problem. The height is likely not a problem either as well be on a barge which is 10 or so feet high.

    Driving piles with a 15 ton excavator and rock hammer.

    Kenworth w900 no air,something's frozen

    Thanks for those valuable tips. It does have an air dryer,installed a few years ago,but I've never done much else to help with freezing. I should have stayed home! Anyhow I figured out it's losing air at the rear relay valve?The valve above rear axle that sends air to both rear wheels. Coming...

    Kenworth w900 no air,something's frozen

    It got cold here,minus 10 Celsius,that's cold on the wet coast.anyhow I used my old 1981 Kenworth with 3406 yesterday all fine,not as cold. Today it started out fine then lost all air about 10 mins in. Can get it up to 15 pounds if I rev for awhile and that's it. Gauge seems fine I checked at...

    Greasing turntable from cab.

    Good points. I wonder ,on the rotate while greasing scenario, if it'd be necessary to grease both zerks on bearing or if doing one while rotating will distribute grease adequately. On the grease in tub thing,yes it gets overlooked. Recently pulled cover on my PC 75 and there was only water,clean...

    Greasing turntable from cab.

    Thinking of ways to do this without having to get in and out of cab multiple times,reach in over track to get at fittings etc,which I don't really enjoy. Recently I attached my Makita grease gun which has a long long hose,to the turntable zerk on front kind of below cab. With gun in cab,I...

    Regulate thumb circuit flow jd590d

    This is a flail mower I created out of a new Holland 918 mower.I calculated the volume of oil available in the thumb circuit by timing the cylinder and doing the math. Bought a hydraulic motor from princess auto that roughly met the calculated spec.Turns out there's more volume than I need in...

    Regulate thumb circuit flow jd590d

    Ive been running it for several seasons as is and its quite adequate ,Im just hoping to improve it a bit. When Im brushing the way it is,the only time i really have an issue is when Im on a hill and go to swing uphill with mower engaged;it wont really do it unless i disengage cutter for a few...

    Regulate thumb circuit flow jd590d

    I screwed the knobs all the way in and pressure on test gauge stayed same so I'm guessing they're for flow. The recent valve pictured is on an old hiab crane in my boneyard that I think is a pressure reducing valve. Not actually sure in that.

    Regulate thumb circuit flow jd590d

    The knurled knobs seem to be for flow not pressure so I'm looking for a pressure reducing valve .Reached out to Wainbee but no reply yet..Have this one I might try and refurbish.

    Regulate thumb circuit flow jd590d

    So on investigating it is possible that my thumb solenoid valve has pressure regulating capability .there are a couple of knurled knobs that I cannot explain except they might regulate flow or pressure. Photo attached . Not a great photo but the knobs are underneath the solonoids.

    Regulate thumb circuit flow jd590d

    Measuring flow is easy I just put an rpm counter on the mower.And I have the circuit pressure set at the valve bank. I wonder if I can use a pilot valve off my parts machine, hooked up in series with the electric thumb control,and set to the flow I want. Thinking of maybe the travel control...

    Regulate thumb circuit flow jd590d

    Running a brush cutter off my thumb circuit.Cutter only requires about 2/3 the flow available and I have the cutter rigged up with a flow control valve that diverts excess flow back to tank. (Both the return flow and the excess flow go into the 1 inch dia return line that runs to end of stick...
