hey guys, I've been reading here for some time and decided to sign up. I own a CR9070 with about 320 sep. hours. Last week I had an "out of nowhere" hydraulic noise in the steering that within a minute got very loud when turning the wheel and when I got to the end of my field to lift the header it abruptly jumped a little then locked up...followed by the steering locking up. I idled down, checked for leaks thinking I was out of oil and no leaks, and I was not low on hydraulic oil in either resivoir. After that episode it did not show up for the rest of the day. The next day, 1 hour into harvesting it did the same thing, noisy steering and noisy header lift. Again, just once that day. The next morning I start the combine and imediately get "control pressure low" and it shuts down the engine. My control pressure was 244. The dealer came out, took out the adjustment valve or whatever for the control pressure, cleaned it out, put it back together and it was an immediate fix. 500 psi, so we adjusted it to 330 and away I went....one hour that same day into harvesting here comes the steering noise, only it doesn't seem to want to go away, and seems to get worse the more I use the header lift. Next day it was cooler outside, and I restrained from using my header lift only when needed, and when I did I went up and down slowly with it. Went all day without hardly a peep. We are cutting sunflowers with my almost new 30 foot rigid head with seedeater pans with the rotating drum. Same thing next day, minimal use of header....hardly ever a noise all day. We are sure we are not getting air in the system, and does not appear water either. Today we drove around our field with the machine and head engaged but not cutting crop for over an hour up and down turning around almost constant without making it act up....what is going on? Anyone ever had this? Why on warm days would it be worse. We did replace the needed filters, but I'm convinced on a warm day it would act up again. Oh ya, and while we were driving around after the inline hydraulic filter change(the other filters where changed the day the adjuster stuck) we drove around for 45 minutes again trying to make it act up, followed by my engine fan bearings going out...took out most belts and both bearings. not a fun job to take out. We had to pull that whole bracket off so they can press the bearings out. But anyway, any help is appreciated and thanks to everyone on here for all the great pics and videos on all colored sites! Thanks!

We have a 04 CR970 and its been acting up on hot days. The header lift spool has been sticking and heating up the hydraulic oil. Its going to take a little bit of polishing but should be good. I would check out the priority and steering valves in the main valve block. There might be something sticky or gummed up that is causing your trouble. The control pressure thing I would think is unrelated because they are separate systems.

yes, its very frusterating....you know whats more frusterating is that I am still broke down with that bearing for the engine fan... When my mechanic got it apart back at the shop he thought the shaft was damaged too bad, so here I sit, not a shaft in sight, supposedly "the depot" whatever and whereever that is will be getting 4 Monday or Tuesday, meaning Tuesday or Wednesday I might get going again. I will have missed a whole week of combining, and that was after sitting for 3 days from a rain delay. I am very frusterated and this is very insulting to me. I dreamed of owning my own New Holland combine since I started combining corn on the living room carpet......this has been the ultimate disappointment. I didn't lose 1 hour of sleep or think much about it when my wheat crop this year got laid flat from hail, I'm a pretty calm guy, and give people the benifit of the doubt, but I can't sleep at night, I can't think about anything else during the day, and when I do sleep its somehow on my mind eating at me almost all night. I'm a hard working 27 year old trying to get ahead in the occupation I love, but this week has me wondering if I should be doing something else.

thanks jester it just seems to me there should be a system in place that no matter if my combine here in South Dakota or someone in Texas or wherever they are can get parts overnight if not in two days. My feeling is this. Dealers like mine who have several machines out, should have on hand every filter, air and fluid, every bearing, every belt, and then every so many stores would have things like sensors, pumps, chopper knives etc. My feeling is anytime a bearing goes out there is potential its gonna spin in or on whatever its mounted too, thus at least one spare should be in the system somewhere. Its rediculous that the belt on the engine that spins the alternator has to come out of Regina Sask.!!! Control pressure sensor is in Toronto! And 5 days to just get a shaft to my dealer.. A few years ago we had a cross auger break on our Cat 480. Butler in Jamestown ND had one. by the time we got it taken out and up to Bismarck to our dealer they had it in hand. now I know there is a rack of augers at the factory, but I would bet money out of 45 Titan Machinery dealers not one of them have one. So lets see, back to my combine, Matching belts that turn the engine fan came out of Wahpeton, the shaft who knows where, another belt out of Regina, one of the bearings in Highmore SD and another bearing from "the depot" The parts distribution within New Holland is crippled. Titan won't carry parts, new holland does nothing, and basically I feel like if something goes wrong I will be down 2-3 days minimum, even if its minor. Better luck to you guys, finally finished our flowers last night with out Cat. on to custom work this week

What about the fluid? What brand and type are you using? I know there is a big difference in fluids. Hytran ultra is a far superior fluid to Unical hydraulic tractor fluid. I proved that a couple years ago to myself. I would think with a machine that relies so much on hydraulics, fluid quality would be very important. Anti foaming agents are very important in modern machinery.

Does this new header have some new hydraulic driven things on it?

The dealership thing aint going to get any better till it gets a whole lot worse. If you want any parts to be available right away, you'll have to buy them ahead of harvest and have them at your shop.

thats too bad for New Holland, I think they have pretty good products but they can't support them. Well as for the fluid I only have 320 sep. hours on the whole machine so whatever they put in there at the factory. I added a little New Holland oil 134 when I changed filters to top it off, other than that never changed it or anything like that. The book says the entire system for the system with the tank is like 26 gallons, and the resivoir holds about 9 so draining that and changing it wouldn't seem to make sense since you can only change out about a third of it. Maybe I will have the dealer change that black valve stack on the left hand side of the machine....might change oil too I guess if I ever get going again I can take it over to the shop...today we had gusts over 60 and its sitting out in a wheat field where we were driving around trying to get the hydraulics to act up...Thanks for everyones imput!

I know how you feel 2rotors. I bought a '07 9070 with 280 sep. hrs. and had 7 breakdowns or problems with it that kept me out of the field in 85 hrs. Hydraulic noises in the steering that NH finally said"thats the way they are" (right). Auto header height and reel speed problems and yes the bearings in engine fan jackshaft went out ( what fun to get that whole bracket out to press bearings out). Left side cleaning fan bearing bracket broke and fan fell down doing 1000rpm's. Guess what was left of fan blades,deflectors and shroud. Nothing. When the combine was working it is an awesome machine. Had very good dealer support. All parts came fed ex the next morning unless breakdowns were on weekends. But...... I lost all confidence in NH. I know how it is not sleeping well at night. I traded it with 300 acres left to harvest. I hated to throw more money at the problem by trading it but stress is what kills you. Hoping next harvest goes better.

Wow, hope things don't continue that way for me...What did you get for its replacement? Picked up more custom work today if I can even get to it all now...dad is thinking of upgrading his 480 Lexion to a 590, possibly this fall. Any more problems and I'll probably be getting one too. Good luck to you swnd

finally got going today, no hydraulic noise...too cold maybe, or maybe the inline hydraulic filter fixed it, I guess we'll find out. one interesting thing, two of the four black selonoids on the aluminum control pressure block are cracked...the black plastic is cracked, could that cause my problem?

CNH does not care, they sell more than they can build.
Quality control is not there to many horor story's.
But you should have warranty on that machine not that it helps getting going but it brings some cost down, but you have to fight for that also, frustrating for sure.
Dealer is your best buddy..................

Sorry, this thread is 3years old. Ended up being a bad hyd. Reel motor on the header. The problem went away when switching headers. Figured it out with header on and turned reel off and the problem stopped. Also, parts availability has improved quite a bit. As for me there is a lot of positive hope in new holland as long as they don't get carried away by losing quality control which it sounds may be happening again.
