I'm trying to do a complete clean and fluid change on my 1994 Unimount plow. I am finding that this replacement filter is a harder type plastic and is not going on that easy with the pump in the housing. I suspect that I will have to get it farther up the spout than I have it in the picture. Is there a trick to twist them on without breaking them? I will take the pump out to do it, which leads me to my next question, I understand that only two out of the four bolts mount the pump, can you tell me which two it is? Thanks again!

Closest to the fill plug, and the level check plug. If all four bolts were removed it's no problem. There's not much to the pump. Don't loose the o ring on the bottom.

Like Randall said not a problem if all four removed but if your worried just do 2 next to each other. Then check length. The bolts that hold pump in housing are a little longer.

As posted you can remove the pump. Else, you can reach one hand in there with the pump on and persuade (easily) the screen on with a long screwdriver.

Thanks very much! I did try to persuade the screen on with a small crowbar, the angle was just right to grab the flat back of the plastic, but I got it as far as you see in the picture, and then it buckled and I heard the plastic crack on the screen frame. So, I have to pick up a new filter and I will try to get it on farther by taking the pump out, I'm thinking that 1/8 inch inside plastic lip has to sit in the 1/8 inch groove still showing in the picture. Can anyone confirm that positioning of the filter?

Take broken one off. Push new one on all the way.

Foolproof

That's what I needed to hear. Thanks everyone!

DO NOT overtorque those bolts, or any others into that housing either. Torque specs and information in the link above. Attachment for quick reference. Pump mounting cap screws are 175-185 INCH lbs or approximately 15.4 ft lbs MAX.

Perfect, thanks for that info. I am actually in the process of putting a new motor in due to that my original one went into crawl speed for the last two hours of use, and then died. With that in mind, could I ask one more question regarding torque values from your chart above, which screws(on the chart) are the ones with the dab of yellow paint on them, and which screws are the 5/8 on the red flange? It's the screw names that confuse me, motor base cap screw, motor end cap screw, base lug cap screw, I'm not sure who is who. Thanks.

This should help.

There you go! I'm always a dollar short, or one page away. That clears it up nicely. Thanks so much for all of you giving up so much of your time to make these forums so great!

Glad to help! Good luck!!!

my filter did the same thing went on about like yours, I got a flat head screw driver and popped it on , makes a good click noise. they don't give you much room to work with , not sure if it was designed to take the pump out then the filter on

 

[gitrdun]

Absolutely right, push it as far as it will go until it hits that ridge in the metal and stops, and it does make a click noise as it goes into place. It took a bit of pressure to push/wiggle it into place,

so for me, I will just take the two minutes and two bolts to pop the pump out and get a good grip on it to push it on.

You should take the pump out anyway. Then wash out the housing. Remove the angle hoses from the valve body, jack up the plow and flush out the cylinders. This way you are starting out with clean fluid.
