Log splitter hydraulic problems

[oldnslo]

Does the cylinder extend at full speed or how many seconds does it take to extend? What is the bore and stroke of the cylinder? With time and size flow can be calculated.

Possible the hi - lo sequence valve is stuck from sitting for nine years. Since this valve recirculates the oil from pump outlet to inlet it might cause aeration. Cylinder speed above should answer this question

Have you checked the pump to engine coupling? Maybe the keyway fell out.

 

[Tim Boyd]

It takes about 90 seconds to extend the cylinder and about the same to retract, slow and jerky motion in both directions, i also did check the the lovejoy key was inplace and setscrews were tight

 

[4570Man]

I’d guess the pump has about got to be bad.

Is there a filter that might be plugged creating more suction and an air leak?

 

[Tim Boyd]

The cylinder size is 4x28x1.5

 

[Tim Boyd]

Are these pumps able to be rebuilt, if not what is a good pump to replace it with

I’m sure it’s possible, but log splitter pumps are cheap. The labor would probably cost more than another pump. Do you want quality or cheap? The cheapest pumps I’ve found are sold on amazon. I don’t remember the brand but the end is blue and the other end is aluminum.

Im all about being cheap, but I also know when not to be. This is the time I would rather spend good money for better quality. What is a good brand name?

Why not post some pictures first before you continue.
