I have an industrial 202 workbull, I think about 1962. I have some additional info now. I drained out the hydro oil which had water in it and filled it with GL1-90.
As of now, when the engine is running, the lift arms go to the top. Makes no difference whether the PTO is engaged or not, or where the position control or draft levers are.
If I push in the clutch, I can push the lift arms down by hand. They don't go down easily but can be pushed down by hand. If I let up on the clutch, they rise to the top again. Again, it makes no difference whether the hand control levers are at the top or bottom of the quadrant. Before I changed the oil, I could stop the rise of the lift arms by leaning on the with my hand. Now I can't stop them by hand.
I've ordered a new safety valve and some new side cover gaskets, so I haven't removed either cover to look in there yet.
I was just wondering if the symptoms seem familiar to anyone and if anyone can venture a guess as to what my problem might be? Any help on this will be appreciated.
