If your motor is turning quick enough at 20lpm on the 2nd aux, and has the torque to work properly, then patent it quick!
Every mainstream brand needs to be running at 50l/min on those size machines.

Engcon, Rototilt, and Steelwrist all appear to use a 50cc displacement motor, so depending on the worm wheel reduction ratio, in theory they should all rotate at a fairly similar speed when supplied with the same flow rate.
A 50cc motor can only handle 20-25l/min

You’ve clearly done your research, but my ec02 is painfully slow to rotate on the 2nd aux on my e27. It’s been running at full flow on the main aux for around a thousand hours.
20/25 litres a minute is less than most 1.7t machines main aux even.

With the motors driving such a large gear reduction, it’s unlikely they are ever required to use the full torque available from the motor. As a result, increasing the flow rate will simply make the rotation speed faster (overspeeding from there rated specs) .
From exploded diagrams the Engcon units are fitted with two over-centre valves. I’m not entirely sure whether these are primarily there to protect the motor from over pressuring or to help hold the tilt circuit in position when under load.

What is the rated rpm for an ec02? I’ll measure mine and compare.

Starting to look into s type hitches and going to have a go at designing my own.
What size is most common 150 or 180 for the 2.7 ton machines.
Is it best to look at building a Hydraulic hitch or manual for the tiltrotator .

Nearly all s30-180. Rare to see 150.

do it as well as you can,but learn to do it better
......... these days ... started out at 150 though

With your hitch setup on your bobcat have got a changeover valve fitted to the machine to turn on the underside hitch hydraulics on ?

or two manual 3x1s in the lines on the dipper'd be my guess

No 3x1 I just lock off the unlock side of the main hitch. That way the hydraulic constant hitch feed is always pressurising both hitches during work.
It was either you or @CPS that told me the s type hitch would hold like that!
Same on both machines. To fit tilty, you hook it into the jaw, get out and then connect the left side pipes (must be the side that pressurises all the time for the hitch unless unlocking). Lean into cab, press hitch button to lock, dump the tilty to pressurise and double check. Then get back out, flip the tap and connect the right side pipes.
Less hassle than it sounds and a good cheap solution for me. My 3k tilty has made a lot of money like that.

Thank you , few improvements to make but overall pleased so far !
If there is enough intrested I might put together a video of the tiltrotator in action and build process.

It's one of the neatest bits of engineering I've seen for a while and an absolute credit.
I'd be keen to buy one tomorrow.
