Thread: LT230 PTO Endurance limit?

Are you using the maxi drive hydraulic PTO?? Or something else??

How much of this is through the PTO and engine driven systems?

The engine drives the PTO........

I get that, but reference was made to 2 separate systems, one via the PTO and the other direct engine driven.

I mentioned this before, not sure how else to answer your question Weeds.

Cheers, Adam.

Hi Rick,
The system comparison will be about 70:30, PTO:Crank. I will try to achieve as little load as possible from the crank as it's belt driven. I expect to achieve this through running a lower pressure through the crank driven pump.

Then the lower pressure system can be used for lighter loads.

I'm certainly aware of the heat issue. I anticipate using a cooler from an equivalent [hydraulic system] capacity excavator. This is likely to be within the ballpark of a mini excavator, and a 2.5 tonne excavator. (2 separate systems).

Oh got it......haven't seen first four PTO, and didn't realise there was a crank driven option

Only familiar with my PTO drive/winch

Oh I get it.....a hydraulic pump driven off the engine...........just caught up sorry

I would go the PTO option after experiencing a mates engine driven pump on his cruiser

So long as the tcase oil level is correct you'll be fine. But don't forget to take care of the gearbox oil too.

Someone is bound to suggest that you can drag more power to the pump by running highs rengine rpms in a Lowe gear. This helps prevent glazing but does increase fuel consumption and can be unforiging on the gearbox.

I'd not do it that way tho, I would mod up the power steering pump and brackets on the front a larger pu.p from there.

48kw is a lot a lot of hydraulics.. cooling, flow and filtration may become an issue as will the size of the lines your going to run off of the pump, unless your going to be running a very high pressure but relatively low flow pump which I'm not convinced the dogs for the pto Will appreciate.
