The original subject was Re: Fiat Allis 8B steering problem.




I have a Fiat Allis 8B. We ran it up on a stump and broke several transmission lines. We have since repaired everything that was broken but now it wont steer. It will go forward and backwards , and will stop when either brake is pressed but it wont turn. I believe this dozer pulls from the hydraulic oil but Im not certain one of the lines we replaced was a return line in the steering system. Is it possible there isnt any fluid in the clutch? The hydraulic circuit does work as far as blade ho and down. Do you have to fill or bleed it to help fill it? We just recently bought the dozer so we arent incredibly familiar.
 
You would be better off just starting a new post rather than making reference to past posts as you can see it says this message is a reply to--------.
The hydraulic system for the blade is completely independent of the steering, it sounds to me like the steering pump lost it's prime when the line ruptured, check the oil level for the transmission/steering clutches, if it is low fill it up to the mark and try it, if still no joy take the suction pipe off the pump and fill it with oil, there will be a suction strainer that could need cleaning if you got the book have a look as those machines are as rare as hens teeth.
