    We had about decided it was mcv. Does these cause a lot of problems on this series of tractors?

    884 PTO

    Got a 884 in shop thats had hydraulic problems. When it started, the hitch would go up and wouldnt come down. We found metal in the draft control valve, found the pump was going down. Cleaned all the valves and checked everything. A few days later, same problems. We checked the unloading valve and flow valve under the seat, went back to working. The last time it quit, no hitch, no steering, and pto will not come on. We replace the complete valve under the seat and the hitch and steering works. Pto still will not come on. Put gauge on the remote and got 2200 # . I found a service manua

    It was the o-ring thats behind the back plate that was messed up. Glade to know about the seal in the suction tube, I didnt know to watch that. Thanks

    Thats a big problem for you guys turning wrenches for a living. All the guys locally says it getting where at least half the parts they get either dont fit or wont work like they suppose to. On my new pump, the seal on the back plate was about half out of the groove, letting it loose pressure.

    BAD pump. Seal in back of pump blowed. You wouldnt thank new parts would be worse than old ones. Thanks for all the help trying to figure it out.

    Snoshe, you are correct about the shaft. This is a 70 model with open center hydualics. I dont believe anything has been changed. Its just got 5000 hrs on a working tach and Im the 3rd owner. Hoping to have some answers this evening as Ill be in shop today. JaredT, you are correct, lots of stuff thats no account be put on and having to be replaced again.

    Its not, theres a little coming out from the left short axle, but none on the right. On my 1256, theres oil coming from the sides and top, which I know its seen its better days, but it works.

    I have took the remote valves apart, found nothing. With the plate off the back for the center link, only oil is moving is at the front where the gear turns the pump. Also noticed a little oil coming out the bearing on the left side where the short axle comes out of the brake housing. It really dont change with the levers moved. I changed the filter again friday. Didnt cut it open, but it looked Ok, but I had an extra one at shop. The loader plugs in the remotes at the back. I hadnt had a chance to get back to it so far this week. Be at the shop tomorrow. I have done a little checking on

    All 4 are metal. When you look in from the back while its running, only oil moving is at at the front where the pump is located and where the axle cones out the left side, above the pump. I have had the relief and the block it goes in all aprart and didnt find anything i thought might be the problem.

    Simple gear pump. Im gone to try and check pressure on the housing at the pump tomorrow. If its got pressure, i thank ive got a blockage internal.

    I took the tube out and put it in pump then back into housing to make sure not to cut oring. Thats on the intake side and i know it completely covered with oil also.

    Im still having problems with hydraulic problems. Tractor is 1979 model(open center). Replaced pump and worked great for short period of time. Then i lost pressure even worse than before i changed pump. I changed the relief valve with the one off another tractor, didnt help. I have checked the unloading valve which i did find part of an oring that didnt belong. I went back and checked the pump to make sure it hadnt sheared the key and also orings there. I hope to have a gauge monday to check the pressure where it comes out of pump on housing. I dont have enough pressure to raise the load
  14. I still us a 1978 model 815 to shell about 12 acres of corn per year for cowfeed. I had a gas burner which was a older model that most of the parts are the same such as the radiator and most all the cleaning parts. It does a good job, just slow compared to the newer machines everyone uses today. .

    Thanks, I traded for this tractor a couple of months ago, straight 1979 model with only 5000 hrs. Im the 3rd owner. I know the pressure is low as it will pick up loader if rpms go up. I also know i got to put a kit in the hitch cause it falls when tractor is shut off, im sure the orings need replacing. I done all this on my 1086 had years ago .
