Meyer E-47 Will not go down

    I have came to the end of my road with this. I have an E47 plow that I have been working on getting going for winter. The pump on it has been replaced, the valve for down has been replaced, there is power to the "A" coil, however, the plow will not go down.
    I have put the plow on and no dice. The plow will go up and angle in both directions but, it will not go down. If we pull the drain plug it will go down. If I take the valve out I can manually move the ram up and down with ease. I can also get the plow to go down most of the time if I take the vent cap off.
    We have also drained the fluid and replaced with fresh fluid before starting.
    Any help on this would be awesome. Thanks in advance.

    Did you test for power and/or magnetism at A valve? What controls are you using?

    Yep

    There is magnetism at the coil. We are using switch controls.

    Did you check to see if the spool moves when you hit the switch?

    Please explain what you mean by SPOOL. I can tell you that when the switch is put in down you can hear the valve clicking.

    Pull a valve and make sure you can move the internal piston. Use a small pin in the bottom of valve, it should spring right back and move roughly 1/16-1/8". The vent part is bit confusing, it should at least drop a bit since if vent is plugged it would create a vacuum in reservoir.

    And are testing down with plow hooked to lift ram, they can be hard to push down sometimes without the weight of the plow pulling it down.

    Yes we did test the valve and it does plunge and spring back. I read on a different post to open the vent cap and see if the ram will lower and it does lower with the vent cap off.

    Have tested both plow on and plow off. No dice.

    So if it works fine with vent off, replace the vent.

    You can also check the filters, believe one is on the downstream side of A valve.

    I you call it a valve, the little part that moves inside the valve body also known as a spool.

    Okay everyone here is an update. We replaced the valve, and vent cap. Now there is a new problem. The plow now will not raise the blade. Will not even pick me up @ 170 pounds. It will raise with no weight on it and you can push ram down by hand. Any thoughts. Plow would lift blade prior to replacing the valve, just would not go down.

    Bad A valve or O rings

    It will stay up without weight. Once you put weight on it goes down. Before changed the valve it would go up and hold. Now it will not go up at all. Left and right angles work just fine. But once the ram gets weight on it, it stops raising.

    Did you put a new A valve in? Were the o rings in good condition? Was the hole for the A valve clean? Is the check ball still in place under the B valve? Put the old A valve in, does it raise and stay up now?

    Wow there is still a E-47 around.... On my E-60's always replaced everything, motor, valves, and coils, cross over valve. Find them cheap on ebay.... It got old year after year.. 3 years ago i finally sold all my meyer's (still have a nice E-60 pump for sale on C list) Switched to all boss plows and 1 western. It's been great, plows are maintenance free.
    I feel in this business you have to have nice equipment, can't let you down when the snow flys.

    Not like runnin old mowers when they break you can come back tomorrow to finish the job

    Look at the amount of posts in Fisher, Meyer, Western and Boss thread. Who has the most posts looking for help? Western. Which has the least? Meyer.

    Come back and show us a pic of your 30+ year old boss plow if there is anything left. :drinkup:
