IG 444 hydraulic filter

INCase

Well-known Member
tarted the 444 yesterday morning and it fired right up.

But. No hydraulics. 3pt or power steering

Let it run a bit but no improvement. Plenty of hydraulic oil in the reservoir

Pulled the suction line and the filter was very badly plugged. The filter separated from the suction tube. So need a new one.

Looking online all of the for that tractor show a tube with an offset. Mine is straight and 1” diameter.

Anyone know the correct part? And maybe a link?

Thanks.

Are you talking about the offset as show on the linked YT filter for that application? YT IH 444 Hydraulic filter It seems to be a replacement for the original filter assembly for the North American version of the 444 per the CNHI online parts catalog. The part number given there is 3069239R91 although arguably that is not the number shown by YT.
Here is some insight on this found on Red Power about the same filter for a 424 shared by Jimb2, see this link.
Red Power IH 424 Hyd. filter info
Not sure if you have used the CNHI manufacturer’s online parts catalog but it does show a straight pipe on the US version. CNHI US IH 444 Hydraulic diagram
To view the European version click the CNH and enter 444 in the box that says Model - Serial Number above it and then the Euro version should show up for selection. Then you have to choose the Hydraulics Functional Group and the proper diagram of the upper cover/rock shaft housing. I am looking at this on an iPhone, on a PC the switch may require less steps.
I wonder if you could use the offset one and cut the offset section off. Then get a longer proper suction hose that would extend up to the hard pipe.
 
Thanks

Those links were helpful. Don’t understand why CaseIH would substitute something that doesn’t work. NO way to use the pipe with the curve in it. AND the offset style pipe is only 3/4" OD instead of 1" OD.

I was surprised how little room there was between the suction filter/tube and the line to the pump. The hose is 1”insidediameter by 5” long. Don’t need 5” as the gap couldn’t be more that 2-1/2ish. But I’ll keep it 5”

I’ll see if I can get the wix 51666 to work as the one link suggested.

One place close by that may have have a NOS. Unlikely but worth a call.

Thanks again

Pictures show my suction pipe with filter next to it. Just like the guy in the forum like attached above.

well apparently the straight tube type is impossible to find. found a used one for $125 but not sure if they are any good until they pull one.

A couple more questions:
  1. does or can the 51666 Wix filter replace the screen in for the suction tube (looking at other posts linked by used red MN)? or is that the auxiliary hydraulic filter? (#2 question)
  2. does anyone know the filter number for the Auxiliary hydraulic filter (between shifter and fuel tank) ?
  3. there was a rubber tube (not hose as it is very soft and flexible see picture with hit partially hanging out of the hole) just laying in the bottom of the opening where the suction filter goes. Does anyone know what this is or where it is suppose to go? it is about 5-6" long maybe 1/2" ID?

Thanks again

Can you send a side view picture of your tractor showing where the WIX filter is located? It sounds like an added-on secondary filter.

I recently replaced the suction filter on my B434. The new one came from a company called Atlantic products out of Florida. I think they are importers of parts made in India where there were a lot of the B series tractors. They share many parts with the 404, 424 and 444 series tractors.

If you send me some measurements of your damaged filter, I can compare it with the old original one which I still have.

The rubber hose that came out of the reservoir might be from the filter assembly. It certainly doesn't belong in the reservoir.

does the one you got for your B434 have a slight dog-leg in it? Seems like all the ones online have that dog leg and are 3/4 diameter. I think there is one (used) on ebaay that looks like someone cut to length and welded a tube on the outside to get it to 1" OD.

not near the tractor so i cannot measure it. I do have the tube part so i can measure the diameter where the filter/screen attaches after work.

Yes, the B434 filter has the dog leg. The replacement matched the OE part I removed.
 
The company that imported the filter is Atlantic Quality Parts. It was made in India. Their part number is 1701-2203 and the CIH reference part number is 3044368R93.

The filter diameter is 1.7875". The length including the O ring abutment is 6.25". The abutment is 1.934" +/- diameter x 0.75" +/- long . The stop flange is 2.125" dia x 0.186" thick. The outlet pipe is a dogleg 7 " overall length x 0.817" OD and 0.682" ID.

In holding the screen up to the light, there is no hose inside the screen chamber.

hello Joe,
finally got around to measuring the end. looks like the part with the o-ring and flange/abutment is the same size.

can you tell how the screen is attached to the tube/flange? my old one looks like it might have been glued or expoxyed together. I think the screen is steel or stainless and the flange/tube is aluminum (didn't think to put a magnet to it) .

are the new ones steel? the pictures look like they might be. wondered about taking a new one and cutting the dog leg tube down and welding a new 1" hose barb/fitting on the correct length (might be a trick) looks like there are come companies that make weld on hose barbs, probably for tanks and things. may not find the right length but could maybe get a longer hose to make up the difference. the current hose is 5" long but I don't think there is more than 1 to 1-1/2 inches between the tube ends. not ideal but it seems the originals, even used are hard to find.

Thanks
 
here is one hose barb. looks like they will cut to length so could get it to match up if the ID of this fits over the dog leg tube.

but no idea on $$

this is a picture (not my tractor) of the "auxiliary hydraulic filter" for units with the remote valves. I think this is where the WIX 51666 or Napa 1666 filter goes. That filter is pretty close to the size of the suction screen filter. but paper of course and probably doesn't flow like the screen does.

The new part is definitely steel. It has been plated but I'm sure with what.

I can't recall how the brass filter screen is attached on the new one but the old one seems to be a press fit.

The rubber hose joining the suction filter and the tube to the pump is about 4 " long but the gap between the two metal parts is only about 3/4". I think it should be short to prevent the hose from collapsing.
 
Didn't get a chance to tinker with anything over the weekend other than the tube part of the suction is actually steel and not aluminum as I thought above.

I also found this picture on the redpower site. looks like they went from the doglegged 3/4" OD on the "available suction screens" noted above to the 1" line. I suspect that is why it has an extra hose clamp on it.



I'm guessing the original ones had the suction screen/filter expoxyed or glued into the flange/tube part somehow. Some black plastic like substance is on the screen and some is inside the flange. I have not been able to get that "glue" off as it is very hard.

FINALLY got around to putting things back together.

for the suction filter I ended up the new one that has the too small, too long, Dog-legged tube and heating it up/cooking the epoxy out and reepoxying it into my old 1" straight short tube original suction filter line. seemed to work ok. used JB weld's tank epoxy.

seemed to go back together ok other than the new hose is a pain to slide back and forth on the tubes even lubed up. Almost ruined the hose trying to slide it with channel-locks. I suspect you're supposed to disconnect the line up front maybe?

Also went to change the filter that is under the steering wheel for the 444's with hydraulic remotes (not sure why anyone would buy one without remotes).

the manuals really don't discuss this filter and it was hard to find the filter (WIX 51666). so there were no instructions on how to take it apart. basically it is a round housing with lines in/out and has a nearly press in plug with a spring to hold the filter in and a bolt that goes thru the housing & plug to keep it in place. the plug also has an o-ring on it (anyone know PN?) . because it is at a goofy angle and is hard to push in and get out, lining up the bolt hole is very difficult.

anyone have any suggestions on alignment? I thought about a round punch but I didn't have one with me and not sure if i have one that short. as the bottom side its limited by the transmission top. on the top side being on nearly a 45deg angle, the dash is in the way. another option i suppose would be to be to take the in and out lines off the housing and do it on the bench but seems like you shouldn't have to take it all the way off the tractor.

One more thing.

the oil inside the housing was kinda thick and also had a strong odor. The fluid that came out of the reservoir was what I would say "normal" viscosity and oil.

the the filter under the steering wheel a by-pass? maybe i hasn't been getting fluid for some time? the old filter was very dirty.


Thanks for the help.
 
thanks. it appears that maybe a Napa SME 187457 is the same O-ring $5.

looks like the IH filter "kit" includes it but at $62. the napa filter (no I'm not a fan of Napa but they are close by and have some odd stuff like this). was $33

kinda wonder about fitting a new O-ring in there. as mentioned above, that "plate" is almost a press in fit. need a slide hammer to get it out easily. luckily there is a threaded hole in the plate

Thank you for this post. It'll help when I get that far.

Is the filter barrel possibly warped & causing resistance when pulling the plate out?
