Where to learn about hydraulics

[mjdtexan]

Hi, I am new to the tractor scene. Finally got one yesterday. Anyway, as it happens I am already interested in attachments and such. While looking at the "do it yourself" section of this forum I saw something that I really want to build. The good ole homemade log splitter. I have an old riding mower's engine that I can use.

The thing is, I know nothing about hydraulics. So, does anyone know a site that is fairly basic so that I can make myself familiar with hydraulics? Then when I do have questions, and I will, I can ask yall without being completely ignorant on the subject.

Congrats on the new tractor. Here's a start: Hydraulics.

I thank you for that, that does seem to cover the basics of hydraulics. Now I need to go drag that old Kohler engine out of that old riding lawn mower.

Thank You, I did manage to find that one. I was reading it when I get the email notification about the thread reply.


I may have a problem already, I just went out back to look at that engine and it is bottom shafted. I wonder how hard that is to hook up to a hydraulic pump?

I don't think Hydraulic pumps care about physical orientation.
They are a sealed unit and should self purge any air that get in quite quickly.

I wonder how I would attach it to the pump

With a coupler. You buy the half that fits your engine, the half that fits your pump, and the flex middle piece. Click here...

Thanks for that. I kinda thought I was out of luck. Its a 17 horse engine. I had almost thought of putting it on craigslist to trade for a 5 or 6 horse side shafted engine. Is that flex piece reliable or would I do better with the side shafted engine? My mind tells me its one less moveable part, but its possible the flex piece is reliable.

You're not out of luck...the 38 series couplings are rated for 40 HP at 1800RPM. All you need is a pump that will give you the flow/pressure you want at 1800RPM and (that one of the couplers will fit - pay attention to the shaft options), a mount that will mount it to your engine, and the coupler pieces...

Notice that the insert (flex piece) only cushions the connection...
