    Bobcat 863F possibly flooded?

    This winter I had the prime bulb collapse during cold weather, 20degrees. I figured maybe fuel gelled so I warmed up a few gallons on a radiator and poured that in. Resolved the issue... Until it happened again the next time I ran the machine, this time at 60degrees, spring time. now I figured...

    Tilt and Lift not working on Bobcat 863

    Well it rained quite a bit last night and the 863 is bugging out. worked for a while then hesitated for a while then worked etc... I alternate between using the BICS bypass I created and the original setup. sometimes one works, sometimes the other, sometimes neither. Most of the connectors I...

    Tilt and Lift not working on Bobcat 863

    yup, mine is same. It's a 1999(manufactured in 1998). Has AHC but analog(not digital) gauges. I ran mine yesterday for a few hours, parked it while it rained, and when I ran it after the rain I was getting hesitations when using tilt and lift at the same time. kept running it and problem went...

    Tilt and Lift not working on Bobcat 863

    Howdy kilohertz, Fortunately I was able to return that ridiculously expensive upgrade kit... It seems my machine had a few issues which did not necessarily happen at the same time but did create a continuous flow of malfunction for some time. The main problem seemed to be that one of the relays...

    AHC to manual foot controls conversion

    Anyone with experience installing manual foot controls on an older AHC Bobcat? Any advice? Seems pretty simple except it's been mentioned to me that at some point the AHC models started getting different valves/spools/BICS and so would have to be replaced with one compatible with foot pedals...

    Reinforcing Loader Arms

    Wow! thank you all for responding to my inquiry. I definitely understand the concept of how every little bit of weight adds up and decreases the lift capacity. Seems like the consensus is to remain with the original design and I agree. The 500°F preheat is what was recommended for welding...

    Reinforcing Loader Arms

    Seems to me that the plate used to sandwich the arms where the lift cylinders attach is about 1/2". and since that is what I would be welding to, then I thought it would be good to match it as close as possible. Yes I definitely plan to preheat, I usually aim at 500°F and test with my infrared...

    Reinforcing Loader Arms

    Specifically on older bobcat skid steers, has anyone reinforced the loader arms to gain rigidity and strength? I've noticed that my machine being an F series has less welded structural reinforcements (between the arms and on the bobtach) than the later G series version. I'm thinking of...

    Actuators

    Thank YOU crewchief888!:notworthy It seems to me that you are a truly crucial member of this forum Update: Turns out I must have moved some gears when originally cleaning the actuators. Today after messing around for an hour or so, I figured out how to manually reset neutral and got the older...

    Actuators

    crewchief888 has definitely presented the most comprehensive response to my question so far. I was just surprised when the person selling part number 7101672 told me it would work fine in place of 7104842. I don't plan to risk using the incorrect part number at this time.

    Actuators

    is this definitive? the reason I bring this up again is that someone who is currently selling an actuator with part number 7101672 told me that it should work fine in place of 7104842. it would be nice to have a spare for a good price.

    Replacing Bobcat hand controls with foot controls

    Has anyone successfully replaced tilt and lift actuators with foot pedal operated linkages? I'm guessing this involves somehow modifying the BICS circuit and changing part of the instrument panel? Are the tilt and lift spools the same length? What is the minimum amount of parts I need to...

    Tilt and Lift not working on Bobcat 863

    new controller kit After many hours of troubleshooting over the course of about a dozen phone calls with a Bobcat service technician(trains Bobcat dealers),who in addition to his own knowledge corresponded with some "old timers" who worked at bobcat during the building of this model, we came...

    Replacing Bobcat loader control valve seals

    From what I've been told, this machine is pre calibration... it's a 1998 AHC(advanced hand control)model, a very early one with analog instruments. it has a metal box controller with the round(cannon) harness. if I did have to calibrate the controllers, i'm guessing I'd have to do both since I...

    Replacing Bobcat loader control valve seals

    Since I resealed the spools in my 863F the control valve lock will not disengage. On the left hand control I get a code(two flashes from right LED) telling me that the "control valve spool is sticking or not centered during shutdown". the other option(according to the troubleshooting chart in...

    Tilt and Lift not working on Bobcat 863

    Do you have the diagram for what the flashing on the left handle means? my left light is on and the right one is flashing two times,one pause, repeat. When sitting in the seat, the BICS panel behind my right elbow just has the Valve lock light completely off(no blinking) all other lights are...

    863F Valve lock

    I was able to test the wires by having the AHC controller in the cab with the engine running and the seat bar down. I sliced lengthwise into the wires so that I could get my volt meter probe in. something that I noticed while I was walking my dog after the test was that the tilt cylinder had...

    863F Valve lock

    I've got an 863F with AHC. Drives fine but no tilt or lift. Valve lock light does not turn on at all(not blinking):confused: back-story The tilt and lift was locking out whenever I used the tilt so I replaced the tilt actuator which was full of hydraulic oil with a new one. While at it I...
