MD Filter Follow-up Question

So I have not yet been able to come up with the filter flange parts for my MD Auxilary Diesel. My Diesel filter assembly uses two filter types. The Primary filter uses a cartridge that fits into the machined cast base. The Aux Filter uses the yarn spool and is intendted to have upper and lower retainers with the lower retainer sitting on the cast base that is less machined. It is basically a washer with a shoulder on it. My follow-up question is that it looks like WIX makes an Aux filter(Part# 33147) that is a cartridge type filter with a flat base with a gasket. Has anyone ever used this filter? If so is this filter just intended to sit on the cast base? Or is intended to sit on the retainer like the yarn spool type filter. I will try and attach a picture of the aux filter.

i asked about this at caseih when i got mine and they said that these 2 are used in place of the yarn one.
i dont exactly remember now how the bases were, but if both bases are the same and both these filters the same then it should be good to go as spring pressure pushes on them.
a pic would be nice.
as a person wants a good seal on btm and top.
 
The final filter is definitely different as it has a neck on the bottom of the filter that fits down inside the machined hole. This filter is a WIX33148 and similar to the IH one that I bought. There are some people that say that you can use this filter for both but on the unit I have the hole is not the same size and not machined. I have read that on the 400's and WD/TD's that the later ones had two machined holes and used the same filter. Also there is no spring that holds the filter down. If I had the retainer/flanges it would really not be an issue. Anyone have suggestions for good Farmall Parts Yards that would have MD/TD6 parts?

I have a extra base that takes the same filters in both if interested in going that way. Probably needs some clean up.
Yes you find the early type that someone put the filters in, but unless they used the adapter the fluid is bypassing at the bottom.
IH started using the same filter type bases during 400 production.
 
Could you send me some pictures? I would also not want to do any replumbing if the connections are different. Did yours come off an MD. Also I have an "A" pump if that matters.

Thanks
 
May get the picture tomorrow. Its off a D281 engine. Fittings all in the same places. Would need to put your cans and water trap on it. Don't know the model MD you have, but if a line has different fittings on the end. Your fittings will screw right in to the pipe threads in the base. Should have the bolt to include for the can. If you notice the shoulder on the sock bolt is a different length. Shoulder like the other bolt is used with same type filters.
 
Back side of a MD and the one for both filters the same closest. Only difference in the other side is the aux filter hole opening size. Real late MD can have a casting that looks the same on the back side but hole sizes are different.
Different filter bolts for MD pictured. Both the long shoulder bolts used with both filters the same.
Only about a 1/16 size in some hole openings. Fellow could probably make a thin sleeve to work and put a spacer on the original bolt if wanting to put a finial filter in the aux.
Casting I have needs a good cleaning and was selling cheep just so someone would get some use from it. Email is open if interested if not thats fine.

Not sure if you found a resolution to your problem yet. Your post reminded me that I had the same problem as you only I was missing both the top and bottom pieces. I just ordered the above part number from FP Smith and it is supposed to be a kit that contains all the parts #22 covers from your part drawing. It was $25 for both plates, gasket and filter. I haven't got mine yet, so I hope it is what I think it is.

Thanks for the advise on Hasken Tractor. I called them and they are going to ship me the entire filter unit assy with all the parts for new style filters in both sides. I also scored a hour meter from him. I hope it works.

No problem. I acutally got an hour meter for my SMTA when I was there. It is dated a little too early for the SMTA, but it is better than the tin plate that was there before!
 
I had an hour meter on the MD tractor I have but it would not turn. I took it apart and it seems pretty clean but the individual digits do not rotate on the cluster even though it does not seem to be froze up. I am not really sure how that mechanism works or how to get it apart. I like fiddleing with this kind of stuff but did not want to break it. I found out that there is a Stewart Warner type and one other that I do not recall the name. I read about it on this forum or an old thread on Red Power.
 
It would have been nice to know that these were available but at the same time it would be nice to be able to run two cartridges rather than one cartridge and one yarn filter. One issue that I am having it that the clearance on the diesel sediment bowl screw hits against the frame and therefor you cannot easily remove the sediment bowl. It seems like there should be more clearance than that and based on how the frame rails are there is not really any way around this. I have verified that the sediment bowl that I have is 4" which is what is shown on a few aftermarket sites. I am curious if you have an MD how much clearance you have. Thanks
 
So I got my new diesel filter assembly mounted on my MD. The new assembly is much cleaner than my original and has machined surfaces on both filters. The issue is that the AUX filter opening is bigger than the Primary Filter. This means that if you use a Promary Cartridge it fits very loose in the opening. A little frustrated at this point so I called FP smith and they are shipping me the parts kit for this.

Hey whats the casting number on the filter base you got.
 
I am not at home but I recall 9441? I see that case/ih shows it as 9441DA. It may very well have the DA on it. I know that mine was original with the tractor though. I can check when I get home and let you know.
 
9441DA used the 2 different filters. Filter base with 6 numbers used 2 final type filters. If I remember correct 9441DA was channeled looking toward the 2 bolts that mount it and 9441D was rounded looking at the same place. Rounded type was on most MD. IH changed the frame rails along the way, some have dips for clearance at places and some don't.
 
Mine is definitely rounded. I think now that I have the upper and lower retainders coming I will be all set with what I have.
