We just repacked the 2 loader cylinders.
I did add about 2 gallon of fluid that was lost.
Afterwards it seemed all OK for about 30 minutes, but now the loader will not raise at times.
It's worse after the machine warms up.
It's most noticeable when the empty bucket is on the ground.
More engine RPM's helped at first, then it would not raise at all.
I can let it run for 60 seconds then it will raise the loader maybe 4". Wait, repeat etc.
After the bucket is half way up, it will easily raise it on up to the top.
I have stroked the loader bucket top to bottom several times to get the air out.
It does have trouble going all the way to the bottom because it seems too weak to raise the machine.
And at the end of each stroke the engine seems to load up.(At least somewhat)
I tried lowering the stabilizer arms and it seems too weak to raise the back of the machine.
So the problem is common to the loader and the back hoe.
The hydraulic filter was replaced about 50 hours ago.
