any hydraulic experts?

The measuring system regarding gallons per minute verses liters ,litres what ever would be different .I'd imagine though a 5.5 HP engine would handle 8 gallon per minute on a two stage pump which is what you want for a log splitter .Most two stage pumps can be preset as to where the low volume pump kicks in .

 

With a 4 inch cylinder it would split about anything although not practicularly fast it certainly beats an axe .

am i reading it wrong but if you look on flowlift website on the log splitter kits look at the individual price for components in the kit. then price them individually on their website and for the same parts some are £100 cheaper!

yeah the g/box oil filler,but if using tractor hydraulics it will be slow,spend a bit more and get a pyo g/box pump,i got a 270 driving my home made splitter.

 

 

 

Sorry if this is thread-jacking,

 

I had a similar idea to make a vertical splitter from a JCB ram to fit my tractor (Leyland 272) anyone know what sort of valve I'd need to to do this?

 

Does the return from the valve go into the top of the block on the tractor?

Thanks for that mixedangased, can you give some details of your home made jobbie, pics would be great

Have a look at my thread mate. I used a 13 horse engine, jcb 3cx ram and a flowFIT bucher valve. As far as a ram is concerned I think it's all about the piston diameter and the body diameter. For a given pump the bigger the piston diameter the more powerfull it'll be but it'll move slower, if the piston diameter is for example 2" and the body is 3" it'll return faster (I think, not 100% on that bit)

Close but not quite, the piston and the body diameter (bore) have to be the same or the ram won't work, what you are referring to is the rod diameter where you are correct, the larger the rod diameter the quicker a given pump will be able to return the ram to the closed position. Bigger rod = less open volume in the bore and hence needs less oil to fill.
