I think that I am on the trail of a bad valve... I had an interesting idea, and that would be, that if the arms have trouble going up due to a piston related problem, such as rings, or just a lot of wear, then the arms would come down quickly, because they couldn't hold pressure.
Well, I fired it up, and let it take it's time to get the arms ALL the way up to the top, I am sure of it, couldn't pick them up anymore. Then I shut the machine off, and just sat there and watch to see what would happen. I instantly heard a weird bubble noise, I look in, and below the pto shaft, air is bubbling up through the oil? So I go around and stand on the lift arms. They start to go down, in surges, and for evey surge there is a LOUD bubble in the oil. It went down about 2 inches, and then stopped. From this point, 400lb's couldn't make them budge.
So, if I am correct, that should eliminate any possibility of a piston related failure, right??
If that is the case, then I figure that it must be a valve, or the pump just can't get enough oil, but then how is a person suppose to explain why it does go up very well at first, and then it all falls apart????
Getting close, I can taste it...
However it tastes like 80-90... EEEWWWWWWWWWW!!! :)
