Hydraulic chain saw question

Tree guy wants me to build a processor for him. He brings over a pole saw and says the bar and chain can both be bigger. Assuming this is true, is this thing going to have enough power to be worth the effort of adapting and installing it?

I'm gonna go ahead and say no. It'd be like cutting a 20 inch oak log with a weed eater engine. I am a hydraulic engineer by trade and could do a power analysis if you know the displacement of the saw motor and pressure rating. I suspect it wouldn't be near effective unless you spin it at 100,000 rpm with chain speeds approaching the speed of sound.

Looks like a Freemont, with 3/8" ports. There are some numbers but I have no idea what the displacement is. The pressure is 138 bar.
I did find what I think is a bigger high speed hydralic motor today, so I may just start from scratch.
The thing is, even if this little saw took ten times as long as a larger one, it would still be an increase in production for the guy.

Me too. I guess once a log hits the stop, 20 seconds to cut instead of 2 seconds will still be faster than bucking off a pile of logs on the ground with a gas saw.

This is the saw;

If it doesn't have a prayer of working, I'll try to do something else, but this is Cape Cod after all.

Total joke? OK, that's why I brought the topic here. I don't know jack all about hydraulic chainsaws.

Any leads on where a decent sized motor could be sourced?

Thanks, I realise that, but I am working within the customer's parameters. He still thinks the little one will work, but is willing to sell it and buy a bigger one. He is going to power it with an extra circuit on a boom truck or skid steer.

At minimum flow and pressure the horse power would be about 2.5 at max pressure and flow around 8, So it's in the range of decent hand held chainsaw.
Surpluscenter.com has some reasonable hydraulic parts from time to time

This one would do about 14 HP at rated pressure and flow. Might be hard to find a large enough sprocket to make the 1116 RPM speed work unless you upgrade to harvester size chain.

No thoughts of mounting a gas saw on a pivot? Saves an awful lot of fabrication and $$. Lots of smaller processors run this way.

Yes.

So it sounds like it would work if it were fed enough juice.

Still working on getting the exact specs.

The flow for the skid steer is 19.1 gal/min. Havn't determined pressure yet. The flow should be effective for what he wants.
