Allis chalmers 190xt steering problems

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hey everyone, had a question on my allis Chalmers 190xt Gasser. I just bought the tractor as a nonrunning project. it have around 5k hours. It had a loader on it that I already took off. The previous owner told me the hydraulics went out on it and it was parked. Before I tried to start it, I removed the pump and took it apart. I also made sure that the engine was spinning the pump. Started it up and pump was pumping oil. However the problems starts when i try to turn the steering wheel the tractors front wheels and the steering wheel will turn a little. However when I turn the wheels more than 3-4 inches the steering wheel jumps back in the other direction. Is the steering system need a special priming method or? 

Thanks

	No priming needed other than turn the steering wheel. So, what did you do to the pump while you had all 100 parts scattered on the bench ??? A seal kit for each of the three sections ?? Those pumps aren't for a novice as there are several different ways to reassemble them WRONG.

	I labeled each section, put line up and marked each section and took a photo before i took it apart. It has pressure, the steering wheel just jerks out of your hand when you get to a certain point. I tried turning the steering wheel a lot. The remotes and high and low work fine. I will check pump again tommarow. Could it be someting in the steering colomn? Thanks

	Doubt it. Make sure the vertical priority valve spool on the rear of the pump is free to move up/down and the spring pushes the spool down into the bore. No new seal kits ??? Edited by DrAllis - 9 hours 13 minutes ago at 5:27pm

	Are you sure the axle spindles aren't rusted tight or packed full of old hard grease?

	the spindles are free. Also have a question of the 190s pumps. Is the priority valve the assembly under the 7/8 inch plug on top of the pump the priority valve? when I took the pump out of the tractor I first removed that plug and there was no spring. Am I just not looking deep enough into the furthest back section? I did not take the whole back part apart only the front three sections. Am I missing something in the pumps back? Also on the seal kits I did put new orings in the groove but not new plates and composite seals. The little plates where still straight and had no scratches or grooves on them. Do you think is should open the pump up again and replace the little plates and composite seals? Thanks for the replies DrAllis and youngorange2000 Edited by Allis Eli - 3 hours 55 minutes ago at 10:45pm
