Will you be selling the hydraulic filter kit for the QH12 soon because I really need one? I check your website everyday hoping to get one before they sell out.
Cushion valve got me thinking about an annoying issue with my boom cylinder. I have a 2t , reasonably higher end 19h0 Chinese Ex. Cylinder mount on top side, so more down force than lift. When I go gently in the lift or up direction and close the valve many times the cylinder will violently pogo stick until the boom retracts to the ground will the control is centred. A video on this would be a real good idea, I think metering the cylinder may cure this. Or may may I should turn the cylinder around for lift power and reduce the downforce. The pump puts out 15 g/m. The machine is new. Really enjoy your content.
These videos are awesome and well done. These minis are a niche market for sure. I didnt think too hard about the slew of the machine but I did consider that sproket a weak point.
My god these things are twitchy. Maybe you wouldn’t know if you didn’t come from large excavator use. Some decent engineering se the factory could have made them so much better at very little extra cost.
I am a guy who learns the machine as it is. That said, running this machine compared to my good stuff, sometimes weighing in more than 20 or 30,times the weight of this, This machine is twitchy as hell! I can learn it as is, but, I don’t want it to effect what I know. Thanks!
I dont own any of these but I'm sure I'll come across one soon enough. You have a great way of explaining things. It's nice to hear someone knowledgeable on here. Can't wait for more.
Wouldn't 2 small hydro accumulators do the same thing? If so, they would effectively 'lock' the swing once they recharged. Also an accumulator probably wouldn't require a dedicated blow-down/discharge line.
Hey there! I just bought two SCL 850 mini skids from an auction There is like absolutely no hydraulic pressure whatsoever, and I looked at the relief valve and noticed there was no bolt holding it down. By chance do you know the size of the bolt? I bet they might be pretty generic between all the machines
Dingo has a similar system,they have counter balance valves,with a variable throttle between A and B.The throttle cushions the stop,and the counter balance slows the overrun (like going downhill).looks a great idea.
Hey there good afternoon. Really appreciate your helpful videos, had a question about tracking down hill. Was hoping you could answer? Have new agt L12 actually comes factory with oil cooler already with fan switch but no filter? Any way, when I’m tracking down a small downhill the motor or pump kinda chugs? Like maybe machine is starting to go to fast for system. Kinda lags out.. but when your on flat ground tracking controls and everything is normal. But second your on a decline tracking kinda here system stall out then come back and repeat. Is this normal?
Great video ran equipment for 30 plus years never knew that about hydraulics watched many of your videos about the Chinese minis learned plenty getting ready to buy one witch one is the best price e.g. cheapest lol
Thank you I definitely have learned from this video this will have to be a must. I also would like to know more about the variable hydraulic valves that you sell and how to install
I really appreciate those videos, Looking forward to see if you are able to make any upgrades on the somewhat cheap DCV. I have almost the same machine myself and really need some upgrade for the boom arm which is really jerky. I have some ideas for servo joystick controls with rc servos but have some concerns with safety for that idea. Another is to add pilot control joystick to get some better comfort when digging multiple hours a day. looking forward to see your thoughts and ideas. Keep up the work!
I use a product called true blue but any Teflon based product should work just fine for tapered thread only. Any thread with a metal to metal mating surface or an O-ring should be dry.
