New built 3pt log splitter

[Redneck in training]

No that was at flat idle my RPM\PTO gauge is working but missing the needle I need to order a new one just haven't had the extra cash so I didn't want to rev the engine and not know what RPM I was at. I think that speed will work for me if it will give me enough pressure. I can stand a little slower speed and use a 4 way wedge if it will push the wood through. I am going to try pushing the piece first and then the wedge to see which works best but I am betting a stationary wedge will be much better. After i find out for sure then i will know where and what design of work table and log stabilizers I will need.

Since your pump is positive displacement the engine speed doesn't affect the pressure but only volume. The cylinder stroke time is directly proportional to engine speed.

Think I am going back to the drawing board on this and going to rethink my power system. I believe in this case my best bet is a PTO driven pump.

165masseyky,

I don't understand your logic. Your times are not that bad, and a PTO pump is about $500, and has less pressure.

Ok that being said here is another question. I read somewhere in all my researching that there was an option on the mf 175 & 180 of a "combination valve". This allowed the gpm of the aux and system hydraulics to be combined into one flow stream. Can this be done on a 165 and if so how?

About combining flows. The logic is there because you can combine several pump flows together to increase GPM's.

A 7 GPM pump plus a 3 GPM pump will produce 10 GPM.

Does your tractor have a separate pump for the steering, or does it have a priority valve and one pump for the steering, and main flow.

If you have two pump flows, a selector valve and a check valve can switch the steering fluid to add to the main flow.

If you have the priority circuit for steering, a selector valve can switch the steering flow to add to the main flow.

Okay I managed to get more confused as I kept reading!!

I have a 3pt splitter it plugs into the rear remotes and someone has to be in the cab to run the hyd's ... to avoid this is there a simple valve to mount to the splitter and then just plug into the remotes?

Will the lever in the cab need to be "acticated"?

 

[J_J]

If you have remotes and your splitter is plugged into the remotes, all you have to do is to bungee the lever in the position for splitting. You could use a detent valve for that, but you have what you have.

Ok lets back up a second and take a deep breathe.....OK now maybe I have started this off all wrong. I have this pump in hand that I got during some swapping around that is still new in box...High Pressure Hydraulic Clutch Pump — 2.32Cu In. | Pumps | Northern Tool + Equipment It has a max pressure of 3000psi @ 3000 rpm with 29 gpm at that rate and a 7in pulley. But I am not sure what kind of HP I will need to do that and I cant turn 3000rpm off my pto. So I am looking at different things and trying to come up with the best of both worlds that I can. I can exchange this pump @ northern tool for a pto driven pump but again that may be hurting my cause. The pump I have in hand specs are as follows. If this was your build what would you do? I already have the mechanical part of the splitter finished just working on hydro's now.


11.6 @ 1200
19.4 @ 2000
29.1 @ 3000

Max. PSI

29 GPM will take about 60 HP, and double belts.

What is going to drive this pump?

You should have told us the whole story up front, as I was using your tractor hyd for the data.

The pump you use is based on the HP to drive it.

 

[J_J]

If you had that much pump, why did you limit yourself to a 3.5 cyl. If I could drive that pump, I would have selected a 5 in cyl, 2 in shaft, and using 3000 psi, the push force would be 58.905 lbs, or 29.45 T

Thats what I am asking I had this pump I got from a trade. I realized it probably wasn't going to be something I could use so I was looking at different possibilities. I.E. trading for pto pump. My tractor has a 4.8gpm at max rpm. To me it makes more seance to use a pto pump if I am going to be reving that high at least I will get better volume and only loose 250 psi for the same fuel usage. What do you think?

It has a max pressure of 3000psi @ 3000 rpm with 29 gpm at that rate and a 7in pulley. But I am not sure what kind of HP I will need to do that ....

50.758 HP.

Thank you ... so put a valve on the splitter bungee the lever in the cab and use the lever mounted to the splitter ... can you recomend a valve to mount to the splitter?

Economics....3.5 cost $200 new...5in cost $450 used...building on a budget trying to build the best I can with the least amount of expense as to not prove my wife right when she said go to Lowes and just buy one.

 

[J_J]

I would use your tractor hyd and then use the Prince fast extend log splitter valve. That valve will take your 4.5 GPM, and make it seem like about 28 GPM, and that is fast.

It will still have the ability for high pressure at 4.6 GPM.

I still come up with 60 HP.

Ok anyone interested in a new in the box clutch pump. will trade for a prince lsr valve and some boot lol

That splitter at TSC , $699, and use the fast extend valve $100 at $800 total.

Sell the 29 gal pump, and the valve off the log splitter, and install the Prince valve.

Not trying to spend your money, but you asked for suggestions.

Give us a price with shipping and someone will grab it if the money looks good.

$300 and you ship it New in box never even had the factory plugs taken out. Only been out of the box to be viewed.

Actual formula: (PSI x GPM) / 1714 = HP

3000 x 29 = 87,000

87,000 / 1714 = 50.758
