Oil Weeping From Pump Mounting Gasket

    Today I drained and replaced the hydraulic fluid, then hooked up the plow and ran it through the paces. (It's nice woprking on it when it's 50 degrees out.) I noticed oil weeping from the bottom of the pump mounting, by the gasket.

    Do you think this is a problem that needs addressing? Or can I just let it do this and figure the oil leaking out will keep the pump body from geting rusty?

    Are you talking about the (Motor Gasket)? If thats the case then you definitly want to get that repaired other wise youll loose way to much fluid when you need it most and also you want that reservoir sealed to keepout moister wich will cause corrosion and that is definitly not something you want floating around inside your plow.

    Yes, I mean the gasket on the bottom of the motor. If I just take out those big bolts, lift up the motor and put on a new gasket, will it go right back together? Or is it a bigger job than that?

    Yes it is that easy, Two bolts and replace the cork gasket and the trouble will be solved for about $1.99 and fifteen minutes. Just make sure you unplug the motor plugs so you dont jit something with it and short it out.

    By the sounds of it you didn't replace the screen on the pump inside the reservoir. Next time you change the fluid, get a 7053k and another motor gasket 25861 from your local Fisher / Western dealer. drain the fluid, then remove the motor as you just did to replace the gasket. then remove the actual pump within (4 bolts, 2 of which hold it to the reservoir, loosen all 4 if you don't know which one is which) and replace the pickup filter on the side of it, clean the reservoir out with brake cleaner and wipe clean, Turn the actual pump over and inspect the rubber o ring on the bottom, if all is good secure the pump back inside and replace the motor & gasket. Make sure to scrape away any of the old gasket to ensure a proper seat on the new one. Another trick is to completely fill the reservoir just before you replace the motor & gasket with new hydraulic fluid. It's alot easier then getting a funnel out and bleeding the system all over again. I remove the whole system to the bench for doing all of this. a few small 2X4 blocks will prop the pump up nicely so you can work on it with ease in a warm environment.

    There is also a flush procedure if you wanted to flush the entire system. If you want it, just let me know.

    I would think it would move alittle either way. Besides, if it's got the pressure to raise I doubt it. It takes more to raise then it does to angle. I would be willing to bet that the system, does need to be flushed however. I just did a 1990 speedcast the other week....you want to talk about crud. She runs like brand new now.

    I just read the other post were you left a lot of info..Almost the same I did.. I wonder if he read the post I left him...Just think this all could end up being a controller problem..The board acting up when it want to..That why I recommend trying another controller.........

    In this post, are you going to mention to torque the pump bolts?

    I'll take Pump cap screws for $100 please........That will be 150-160 lbs of torque sir. The motor to manifold however is a mere 30-40 lbs.

    I however, just make them tight. I have a "feel" for things after doing so many of them. Mike may come across the site and smack me for just such a thing though. :dizzy: :waving:

    Would that be inch pounds or foot pounds Ryan? It makes a big difference you know. :D

    It's always a good idea to properly torque the pump bolts however the motor bolts aren't critical. A good single grunt with a box end wrench is fine.

    ewww, I can envision a nasty PM with pictures of snapped bolt heads already! :laughing:. That would definitely be inch lbs for sure. :D
