Volvo EC300D

[RCP57]

A few months ago I bought a Torcman motor and Jeti spin esc off of a former member. I've been wanting to swap out my noisy planetary drive for this for a while so today I finally got to it. This combo spins the pump a far bit slower but the hydro speed is quite nice and makes it a little easier to operate. I ran it for over 1/2 an hour and the motor was barely warm. The old motor setup would have been hot to the touch in that timespan. I'm not sure what the issue is but sometimes the pump doesn't start when you pull a lever. This happened before with the old setup too but not in the first few months of use. I went to use it a xmas after it had sat a couple months and this started happening. Not sure if something has happened to the gear channel(pump runs of it) or what but the servos still operate the valves...few seconds later and away we go....

Any way here's a couple pics of old and new and a few videos of it in use. I got to use the thumb today a bit too!

Thanks for looking

Nice video and nearly a tip over what is the noise everytime you have a large change of pump rpm? some kind of vibration? Your setting is a amazing are the trees behind all part of your backyard or did you go somewhere to film? More importantly when are we going to see the skidder working out there?

I not sure why it makes that noise. I guess the rpm change sends a vibration through the tin can of a body. I think I am going to add some sound deadener to the engine cover so that it shuts up a little more. It is quieter than before but when it makes that noise it drives me nuts!

Yes that's our backyard. I'm very fortunate to live out in the boonies a little and have a pretty big play area for all of my hobbies. Some of my friends always used called it the RCP compound lol.

My poor skidder... It has been sitting on the back of my truck for months now but I have been day dreaming about it more and more lately. I really need to make the hydraulic cylinders for it! I have so many different projects on the go that none of them are getting finished. The truck is my main focus but now that the Mack is working well and the Volvo is tuned up I only have a boat the KW and a wedding to prepare for by mid July... Oh yeah and work...Haha

I see from your videos that your pump is allowed to shut off completely from no stick movement... the surge of amps from the esc to even start these larger outrunner motors is pretty high and when it stops working, your esc is in thermal protection mode. I had this trouble too when I 1st got my 850 running.

To correct the issue, set the "on" side of the gear switch to 20 - 30%. Using mix, the pump will ramp up to the higher speeds with stick movement, and then will never go too slow with slight stick movement, saving your esc from much unnecessary heat build up.

Thanks Joe, I'll give it a try! Is there a way to set it up like that and still be able to turn the pump off? The way I have it now the pump is either pinned at full rpm with the gear switch down, and in the up position it is off until a stick or the knob is touched. I would like to be able to switch the pump off completely if I have it set to run at low rpm while in use with no stick movement.

Thanks, Reg
