hydraulic motorcycle meta

[silvano68]

I bought used an orbital motor of meta hidraulic brand, which reports on the plate op 315 c.
I'm doubtful that the tree doesn't have the bearings but a bronze.
Is there any one of you who knows, and possibly there's bronze can replace it with a roller bearing?
And what's the biggest pump I can apply to you (to have more speed) and to what max pressure?

Thank you.

Good morning
the oleodynamic motor orbital meta op 315 c has the cylindrical shaft supported by roller bearings, the maximum continuous operating pressure is 120 bar and the maximum flow rate is 60 liters/minute.
As for the pump you need to use, you have to do two accounts according to the number of turns and the power you have on the input of the pump.
If you have this data, I can give you some other indication.
Ultimately, the products of the meta company are not at the top of quality, but for economic applications without too much need, they can go well too.

thank you very much for the answer (it was exactly what I wanted to know).

the engine in question will replace a 100 cc powered by a 25 l pump at a max pressure of 180 bar that from the movement to a forest winch.
My intention is to increase the shooting and also the speed, also changing the pump, since currently the engine of the tractor (60 cv) is not busy much.
Can I calibrate the maximum valve at a higher pressure than 120 bar since it is reached for short periods (when the trunk is "planned")?

Good morning
from the engine tables in question you can see that you can get to 140 bar for intermittent periods of max 6 seconds and 225 bar peak duration max 1 second.

Great!
I think I can leave the calibration at 180 bar as it is now.
of course to use with the appropriate cautele.

Thank you again for the answers.
