    Cold out this morning....Plow wouldn't raise, which usually means in my plow, that there is some frozen fluid in the filters. Pulled them out, cleaned them, put them and the plugs back in. One of the plugs won't tighten, stripped. Threads look OK, but it's not the thread in the housing, as the other plug will tighten in that hole. Of course, it' sSunday...so I went to Canadian Tire and got a longer 1/4 NP thread plug. It wont go in...Threads are slightly different. Anyone know what thread that Meyers uses for these plugs? Going to the dealer in the city tomorrow, but was wondering. Will get 2 new plugs and filters.

    BTW, my E-47 only has 2 plugs in it, not 3, and it looks like the filters at one time were attached to the plug. The pictures of the new plastic filters that I see are separate. Anyone know about these filters attached to the plugs?

    The guy at the hardware store called them bullets, they are .10 cents a peace, I use lots of die electric grease, but I have only used them this year so I'm not sure how long they will last. Hope this helps!

    Yes...Them's the ones........hope the dealer has them...

    If I cant get one tomorrow, I was wondering if a plastic 1/4 plug would work....would it hold the pressure of the hydraulics?....I could run it in there, and it would conform to the housing threads, without messing them up, just until I can get a proper replacement.......

    I see the torque caution on the diagram.....I was probably overtightening them.

    Those plugs with the filters are pretty old. There is a replacement kit with a new plug/plastic filter (but a slightly different filter than the curent ones as the "tit" is slightly shorter). The nut is a slightly smaller size than the newer ones also if I remember correctly. That whole pump is pretty old.

    The thread's in the plug hole's are not 1/4 in. pipe thread! Their 9/16 O-ring. If you dont have any luck at the dealer (they should have them though) check with a local hydraulic shop for the plug as 9/16 O-ring is very common in the hydraulic industry.

    I don't think a plastic plug will hold as there is some where around 1500 PSI on the drain and filter plugs when operating the pump. If you have an older e47 pump the plug maybe 1/2"-18thread with a 5/8 head. If that is the case any Meyer dealer should have the 9/16 plug with a 11/16 head and all you have to do is re-tap the hole to 9/16-18 threads and you should have no problems as i have done that on 2 pumps myself. The drain plug and filter plugs are to be torqued to 75-85 INCH lbs. good luck.
