  1. We had a tire dealer put some LSW tires on a Magnum a year ago. Goofy looking to me. A few guys have put them on Steigers around here. Expensive.
  2. The part# for that coupler has changed over the years...your coupler may/may not have the backup ring. The seal kit# is for the newest part# of the coupler. Remove your o-ring and look in the bore of the coupler...if the backup ring is in there and looks good...leave it in there and just put the new o-ring in and be done. If it’s not in there, you will probably have to install the backup ring as I’m guessing the new o-ring is slightly smaller to allow for the backup ring. Good luck.
  3. Farmall 57 is correct, seal kit #87382012 is the o-ring and backup ring for the female coupler. Have your dealer look up bulletin # 2018-046 CIH N SB to confirm this. Just an FYI, if you ever need to replace the female coupler on a Basildon-built tractor(CaseIH MXMs/MXUs and later mid-range tractors), do yourself a favor and tell your partsman you need one for an MX Maxxum(MX100/110/120/135 models) instead of the one the partsbook calls for. It screws right in place, and works MUCH better in cold weather in our cold northern climate in the wintertime. The "correct" couplers are hard to couple hoses to in the winter and pop out hoses in the cold, too. We have replaced several of the "correct" couplers with the old couplers for warranty on several tractors through the years...at the recommendation of CaseIH.
  4. This is the engine diagnostic panel for a 2588. If you have an active engine fault, the yellow light in the lower RH corner should be illuminated. If your fuel system was that restricted, it should be on.
  5. On a 2588, there should be a small gauge cluster right beside the regular A post instrumentation that has 4 warning lights on it. Are any of the lights on? If so, the engine controller has a fault code. Unfortunately, the engine had its own CanBus communication system that doesn’t communicate much with other controllers on the combine for diagnostics, you have to hook up a laptop to a connector in the fuse panel area to communicate with the controller. Cant remember the exact details on this, but there was a problem on some of those that would cause the throttle pot. in the cab to move slightly so the engine computer would not be commanded to run at full throttle/power as well.
  6. CaseIH offers a harness similar to what Jeff is describing.
  7. Is fuse 43 OK? Have you tried swapping the park brake relay(should be relay #5) with another relay just to see if it makes a difference? I don't think the Magnums have a pressure sensor for the park brake circuit like the Steigers do. Was the coil replaced with the park brake solenoid?
  8. Pretty common to see fine metallic material on the drain plug on those every time you change it. Just the nature of the beast. Never seen anything recommended on that gearbox other than Hy-Tran. Now if you use a chopping corn head, CaseIH recommends you use synthetic Hy-Tran on the header gearbox(gearbox down by the header driveshafts) for cooler operation. One thing I would recommend on that gearbox is to make a mental note on the color of the gearbox oil in the sight glass right in the middle of the gearbox. The color should never change...if it all of a sudden gets extremely dark-colored, your slip clutch located inside the gearbox is probably on its last.
  9. Not that I've ever seen. That would take a lot of work for a rather minimal gain, IMHO. Lot of plumbing changes happened when that took place. All the tubes/hoses on the RH side of the transmission were changed, in addition to the gear pumps. I guess if somebody ever wanted to try it....have at it. It has always been my opinion(just that...I have nothing to back it up with) that the decision to use the PFC/piston pump for regulated circuit oil on the early 7100 series Magnums was a design change made by the boys in Racine after they got a hold of the "New Farmall powershift" from IH that would evolve into the Magnum tractor. Case had used the piston pump for transmission clutch pressure/regulated circuits going back to their previous 90/94 series designs...at least on those you were only tying to lock up 2 clutches in every gear instead of 4 with a Magnum. It was bad enough that you lost flow to the remotes by running steering off the PFC piston pump, now you lost even more flow to the remotes by running regulated circuits off of it. Granted, regulated circuits should not take much flow during normal operation, but if you came to a headland and were shifting gears, disengaging MFD, turning the PTO on/off, using brakes, etc. while raising the 3pt. hitch and using remote valves all at the same time, the lack of hydraulic oil became apparent. Also, if you were running a hydraulic motor on a hot day, that 12 GPM of oil to the cooler was insufficient as well. If you think about it, that was no more oil going to the cooler than an 86 series with an open-center hydraulic system that was never meant to run any hydraulic motor applications. As far as hydraulic capacity/output, the early 7100 series were a step backwards from the 50 series IH's like I mentioned, but the later 7100 series were just as good as anything else on the market at the time. Deere was still using their closed-center, high-pressure system with a radial-piston pump that dated all the way back to the 30/4010. Where the classic Magnum fell behind was shortly after the introduction of the 7200 series in the fall of 1993/spring of 1994 when Deere introduced their 8000 series tractors and New Holland introduced their Genesis tractors with optional MegaFlow hydraulics. To put it bluntly, the Magnum became outclassed by both machines in terms of hydraulic performance. As far as the 51/5200 series Maxxums and their hydraulics, the lack of hydraulic capacity was one reason why we did not sell a lot of those for loader applications. IIRC, the piston pump was rated at 20 GPM at full throttle...with only about 16GPM available at the remotes(here again, the piston pump had to run steering and regulated circuits on those just like an early Magnum). Now, if you want to run a loader at little more than idle speed, you were down to 8 GPM or so to operate your loader....made for pretty slow cycle times for loader operation. Add to that the CaseIH-offered loader(the 510/520 CaseIH loader...made by Great Bend), used bigger cylinders that their Deere counterparts and it became readily apparent that our loaders were much slower than their Deere counterparts. The only thing we could brag about was that our loaders had much more lifting capacity because of the larger cylinders...but customers saw the slower loader cycle time first...and that's what usually sold tractor/loader combinations. As far as the PTO setup with the shifting pins...Case used that design on other tractors before the Maxxums. The smaller 90/94/96 series tractors used that same setup, although it didn't seem like they gave near the problems that the Maxxums did. Hate to say it, but the MX Magnums and newer use a different version of that setup on their 3-shaft PTO option that is still being built today. Instead of the 2 shift pins, they use a long roll pin to shift the gears from 540/1000 rpm PTO speeds. The roll pin has a tendency to get bent, causing the PTO gears to get into a neutral position, so that the PTO doesn't drive in either 540/1000 speeds. At least on those, its a much easier repair as you only have to remove the PTO output shaft assy. to access/replace the roll pin.
  10. Major changes to the hydraulic system occurred at SN#JJA0027701 when the second hydraulic filter was added to the Magnum transmission. #1. Oil cooler flow was much greater. The original hydraulic system had just a 12gpm hydraulic pump for the cooler. The improved system could have up to 60gpm of flow at the cooler depending on hydraulic system requirements. #2. The regulated hydraulic system(transmission clutches, PTO, differential lock, mfd, brakes) received its oil from a gear pump, instead of the piston pump on the previous design. This allowed more hydraulic flow available to the remote valves as the piston pump no longer had to operate the regulated circuits. Many red guys that had moved from IH 50 series tractors to early 7100 series Magnums were rather disappointed in the hydraulic capacity(or lack of) of the early Magnums. The second hydraulic filter was for the gear pump/regulated system filtration. This setup was pretty much used unchanged for the rest of classic Magnum production.
  11. I had forgotten about this YouTube video Herbert had done showing the IH photo center as it looks today vs. how it looked when IH used it for a backdrop for many of their 70s-80s pictures for advertising. Grab the popcorn and enjoy. https://www.youtube.com/watch?v=e4Z9aqnd8nw&feature=share
  12. Jack Wise was the guy that was in many IH studio shots from the 1960s through the end of IH. Seen him and his wife(who also did advertising work for IH) at Red Power Roundup in Des Moines in 2017. Like has been mentioned, there has been a few articles in RPM about IH’s advertising department. IH had their own IH Photographic Center in Illinois where they did a lot of their own onsite filming production. Herbert Starzinger visited the place a few years ago....it’s now owned by a local golf course that uses the former IH studio location as a maintenance shop.
  13. Remember HD well; like Jerry said, he used to post a lot. Maybe this isn’t a good idea, but maybe BJ(FarmallFan) should create a memorial page on here dedicated to members that have passed on. RIP Roger....you were one of the good ones....and you will be missed.
  14. Dan, this is the stuff we have used for years. Think we just get it from NAPA. Looks to be readily available from Amazon and other places. More or less acts like brake cleaner as far as evaporating quickly, but supposed to be used for a/c systems.

    windrow wheat

    What WW that has been combined has had yields of 75-80 bpa or so. Unfortunately, not much has been combined for 2 weeks or so due to a lot of rain lately. 6-10” or so in some places around here in the last 2-3 weeks. What’s still out in the field will probably be discounted due to quality issues. Never thought I’d ever see WW harvested in September around here in my life, but it may just happen this year.
