    Snoway 22 has always worked fine. All functions work . But it won't lift now. Motor running but no lift. No leaks fluid is full.

    Here are some additional things that could be contributing to the problem that you or your Sno-Way Retailer should check:

    1. Fluid level low
    2. Improper main pressure relief pressure setting or debris causing valve to stick
    3. Down pressure valve "E" stuck open
    4. Lower valve "B" stuck in the "lower" position
    5. Raise cylinder binding
    6. Raise valve "C" not functioning

    Hope that these ideas can help you solve your problem. If not, post additional details back for further assistance or have your Sno-Way Retailer contact our technical service department for additional diagnosis of your problem.

    Good suggestion, also check the fuse holder wiring to see if it may have gotten broken or cracked. When attempting to raise the plow, check "C" coil to see if it is magnetized. Let us know how things turn out.

    I find this same thing happens to my 29 Series after plowing for a couple hrs. When it happens to me I let the truck sit running for a bit and then the plow works again. I think in my case the alternator isn't heavy duty so it isn't charging the battery enough to lift the plow. Maybe this isn't the problem but it seems that way.

    Increase your alt. any NAPA etc should have a heavier one and up-grade your battery.

    Still Problems

    Still having problems with the 29 Series on the F-150. Changed the Alt to a 250 amp and a new battery. Still won't lift after about an hour of plowing. Starting to think it isn't the electrical though. How do I check the other suggestions made by everyone? I know that the fluid level isn't low but I may have one of the other problems.
    As I said before, it won't lift but will pivot left and right at full speed and down pressure (but is slow).
    Any help would be great!
    Thanks!

    I had a problem with mice chewing on the wires and I found several short circuits. One was with the lift circuit and I had no up untill I fix it.

    What color coils are on the pump, black or a mix of black and blue? Does the motor sound like its struggling when you raise or does it spin freely but take forever to raise/DP?
    does it gravity drop normally? will it angle normally when the blade is on the ground with the DP engaged?

    I would discount fluid contamination, or clogged pick up/return
    filters because it is operating at full speed in the angle function. It could be (in no particular order) a bad lift ram, problems with the pressure relief, failed pump, clogged in line filters (doubtful)

    Mash up some viagra and mix it in with the hydraulic fluid. You should have no problem getting it up then!

    On a more serious note I have a 2004 29 series and I had a similar problem. I had dual batteries with a 150amp alt. it turned out it was just the power cables coming loose. Now everytime i hook the plow up i zip tie the power plugs together.

    Thanks for the suggestions. I will check everything out this weekend.

    Basher, the pump sounds like it is spinning free but just won't lift. It will angle normal with DP on. It gravity drops very slow if I can get the plow up. I will check the coils to see what color they are.

    Meistr, I will have to check to see if mice have chewed on anything but it did this pretty much out of the box so I am doubtful that it is chewed wires but you just never know. I will check the ram as well. Hopefully it isn't bent!!

    Thanks again!

    icudoucme, did the plow just not lift but would swing left and right? The plug seems tight but maybe it is a bit corroded or something. I will check it out as well. I have to find a place to take the plow in and thaw it out. It is covered in snow with the 1 1/2 or more ft of snow we have got over the last couple days.

    I guess I should have looked into this a bit more in the summer when the weather was nice or better yet, when I first got it last year.

    On another note, what do you guys use for hydraulic oil? Any type 5606? And can they be mixed or just drained and replaced. Haven't had to add or replace the fluid yet but it is looking like it now if I have to take something apart.

    Thanks!
    Jeff

    Basher,
    The color of the coils are a mix of black and blue. Could one of these be the problem? maybe only working intermitently?

    I have checked the wires to see if they have been chewed and there is nothing. The wires and connections all look like they are brand new as well.

    I hope I can get this thing figured out soon. We are supposed to get over a foot of snow today and possibly another foot over the weekend. Most of the roads are closed and all businesses are closed just 20 min south of here and looks like the same is headed for us.:cry:

    The mix is good.

    you could have weak coils, dirty connections to the coils so they're not getting a good 10 volts. check to see if the coils are getting at least 10 volts.

    Check your DP, lift and lower valves for complete function. make sure they are not stuck partially open or prohibited from opening fully .

    Basher,
    How do I check the valves to make sure they are functioning properly?

    ports are marked on the manifold. There is a chart of all functions and the corresponding coil/valves stuck to the inside of the cover of your plow.
