Charles Todd Allied Machine Filter exstension

Charles,realy enjoyed your posts on 504 filter set-up,have ordered one for mine,no show after a week.Did it take very long to receive yours? After reading your posts I did some digging in parts catalog,IH did offer a different filter cover for the tractors useing the17 gpm pump,used same filter as folks selling the exstension kits. This cover is no longer available and very pricey,if you could find one.Seems the kit is the way to go. If it ever gets here!!!!!!!!!

Pandora 504, glad to here that you are making a move in the right direction sith your 504. Mine is operating much smoother (less cavitation). Interesting about the cover for the OEM filter. I have the TC-88 parts manual and found the 17 gpm pump, but no filter number or the deeper filter plate.

This filter is my first line of defense. I plan to add a spin on filter (smaller micron rating and better beta rating than IH filter) in my power beyond loader line somewhere. I'll use it as my primary filter and the new filter and extension will be my pre-filter!

My part took about a week to arrive. They had a "waiting list" of people that had called looking for the part. I told her I had been calling for two months waiting for them to be built. She sent mine next day. May want to call Mary (if that is who you talked too) and ask if it was shipped.

Let us know how it turned out!

I must be the lucky one. After reading Charles' post, I called Allied up and ordered the kit w/ spare filter. Just arrived today, less than a week later. I'll have to wait till the weather breaks to install, but it looks very nice.

Did a little research, don't have the service bulletins on hydraulics that go back that far, however, did find out some thing I never came across before,in the online parts manuals, the 656 had a high capacity hyd system available that used the 17 gal pump and the larger hyd filter. I didn't realize that. Now this part I knew all along as I dealt with it, that after such and such serial number, IH switched from the standard 12 gal main pump and 7 gal hitch pump to a 17 gal and 9 gal pump, then used different pump mounting plate and drive gear, slowed pumps down to deliver same gal as smaller pump to reduce hyd noise. That part I knew . I saw some put in the larger pumps with the original gear and plate and the cavitation was terrible. Twelve and seven coming through the small filter was over done and then put seventeen and nine through same size filter, well, the larger filter would have really helped I am sure.

I should have provided the part # for the 17gpm set up in my earlier post to Charles,sorry about that.#is 388083R1 .Uses longer bolts (3/8-16-2) to mount than the standard cover. Filter listed is same # Charles said came with his kit,#385085R1. Almost an inch thicker than the other filter set up. You learn something every day .

Charles, I checked out that filter extention when you posted the link, thought it might help my 340 as she don't like to go to work in this cold weather. It doesn't look like it would fit on my tractor without bending the brake pedals to get the clearance, was that an issue on your 504? thanks PUTTER

Pete 23: Can you tell me what the difference is in the mounting plates so I can look and see what mine is? Not sure why a different mounting plate is needed. Seems like it would be more of a thickness and spacer issue. They used to offer to spacers and now they only seem to carry one.

Also how many teeth did the drive gear have for both the 12 and the 17?

Charles: My 2606 with IH 3000 loader & case backhoe came with a hydraulic cannister type filter that is part of the loader setup. Not sure one is "pre" as compared to the other but at least there is dual cleaning. I noticed when I got my 2606 which was having steering problems, someone had removed the screen from the IH filter down by the pumps allowing open flow by that filter. Ended up buying another one and they aren't cheap.

You have me wondering now how bad do I need that filter when I have that big cannister one coming off the loader valves? The only issue would be any sludge in the bottom of the tranny that would get in the oil. With the loader filter, maybe I'll pull the other filter and screen to see what performance I get.

bc, the difference is the thickness of the mounting plate. The sn break is 13011 that used the 12 gal pump and 15 tooth pump gear, later used 17 gal pump and 21 tooth pump gear, this is with 540 pto tractors. I don't know the thickness of plate, but parts book shows 1 1/2 inch mounting bolts on older one and 1 7/8 on later. Only spacers I ever encountered were the different thickness mounting gaskets to adjust gear backlash. You do need a filter though as a lot of trash, like chips of gears and bearings from trans are always making their way through.

Thanks Pete. I guess the easy way is to remove a bolt on the pump mounting plate and see what I've got. I've been wanting to pull the whole plate and look for part numbers, etc. but I didn't want to open up a can of worms out in the blowing snow, dirt, and below zero temps.

My gas industrial 2606 is kinda a hybrid so serial #'s don't work. The specific online parts manual for a diesel isn't the same. It appears to have the hydraulics of the 656 then some parts match up with the 460, 560, 606, 660, 504, 2504, and a few others.

I understand what your saying about the filter issues. I think the owner before me ran it for a few years without the screen though.

This looks like a good thread to print out to stick in with my IT manual.

Ok, where to begin... So much info has been given since last night! My 17 gpm pump came from Hy-Capacity, not IH. I used the same bolts that were on the old one, actually the pumps looked pretty close in size. The thickness from plate to pump was the same, I think. The bolts had plenty of threads.

I sold my old pump on EBAY, made a good chunk off of a used pump... I used the same gear from the 12 to the 17 gpm. I did not research that one I bought both gaskets and did not look at them first. I installed the thinner of the two by accident. I have not used it much since the new pump (<15 hrs). When I placed the new filter and extension on I noticed some metal debris! I plan to pull the pump plate off and use the thicker gasket.

I had no problems with the brake petals. They are well above the filter on the F504. I will measure the thickness of the adapter plate tomorrow, I have to run tonight. If I had known the thickness and the filter used before hand, I would have not bought the kit. I would have had a machinist at work mill me one out of steel or aluminum using the cover as the template. But $58.00 + shipping ($9.00) was worth it to get the adapter, filter, bolts, studs, and two gaskets...

Let me know if this helps and I will post tomorrow with the dimensions and such on the adapter. Another reason my pump is kicking A$$ is the 12 gpm gear on the 17 gpm pump!!! 8)

If someone wanted to use the cover as a template and had a billet of steel or aluminum available to machine a spacer here is the thickness... 1.104", 28.04mm. Good luck friends.

I checked today. I have 1 3/8" clearance from the brakes to the bolt heads so the adaptor should work.

My pump mounting plate is 3/4" thick and uses 1 1/2" bolts so I guess I must have the 12 gpm. I was afraid to remove the whole plate and pump assembly cause I was worried it would dump all the hytran in the transmission.

Charles brings up a question. If he put a 17 gpm pump in and used the 15 tooth pump gear then he is spinning it much faster that it is supposed to. Will that hurt it or not or will it just put more out at high speed?

I am curious myself. Like I have said before the CHN dealer I use has some guys that have little drive or desire to help when it comes to older tractor parts. They would just soon send me to the sales counter for a new tractor. Even though I had the CNH system and my TC-88 Parts manual I kinda shot in the dark on the pump situation.

I bought the pump online from Marshalls Tractor in KY. It came branded a Hy-Capacity, checked on them, good parts, good prices. I just pulled out the TC-88 and it DOES NOT show the 17 gpm for the F504, only the I504. BUT it does show three different gears for the F504: 14T 501-2469, 15T 2470-5159 (I have this one), 17T 5160-up... I was going to put a new gear on it for grins until I priced one, $180! I was also going to replace the suction tube 395334R91 but it was about $50. I never saw anything on the 21T gear...

For the I504 the 17 gpm pump is listed. It also has three different gears. 14T 501-511, 15T 512-1329, 17T 1330-up... It also says when replacing 373964R92 or 374483R92 also use 395335R91 suction tube.

Interesting enough it also list a tandem filter assembly, less elements for the I504 number 382854R91 and also, package 388085R91, valve 386121R92, cover 388083R1, and six screws 179847 for S/N 501-12265. I had no luck on these items... Hence the Allied Precision Extension, probably much cheaper and better to boot!

This is probably a lot of useless info and obselete numbers. Good luck and if I can help the EMAIL is open as well as the forum.
