OK great I will take your advice. I'll post more when I dig into it and see what I have.

Re: O&K Damitz RH6.6 Big OilPump 750ml
Honestly it looks like the boom and arm are moving plenty fast already. Which makes me think you already have the bigger pump and the issue is somewhere else?

Whats your current status? A (german based) community is also in regular exchange on facebook, so you could subscribe and try to get some help through this channel as well.
Another option is to call damitz directly... |

Re: O&K Damitz RH6.6 Big OilPump 750ml
hey first off thanks for messaging and helping.
current status = I unplugged track servos so I don't accidentally open valves. I don't dare attempt to take this thing apart. It's too advanced and nice for a hack like me to touch. I have no clue why #1. the tracks were so slow because the pump handles all the other functions just fine. Speed on cylinders is good and swinging and lifting at the same time is not an issue. #2. why SOMETHING broke and the tracks don't move and it just dumps oil when a track valve is opened. I am trying to get a hold of diggingwithmartin and see if he can help. He is only about 3 hours drive from me and he has done work for others before. As of right now that is my plan. anyone wanna buy this thing?? hahaha |

As for #2: personally imwould try to find the root cause, otherwise you cant enjoy your excavator. I had bursted tubes in the past and its not a big deal to replace it. As for the tracks: did you check the servo movements? It could be very easily that they are limited in their movement, which would result in less pil arriving at your track motors.
Overall: the hydraulic tracks will never be like a "race car", however with your point they should be able to move your machine. Feel free to pm me separately. Rgds, Thomas |

Yes I am sure the servo is opening fully they have little "tabs" on top and it makes it very easy to see the movement and I adjusted the % on my radio so all servos were opening 100%. Also... a burst line inside the slewing area would make perfect sense for what is happening. The rate of hydraulic oil loss is extreme when I open a valve. The tracks were stuck and I kept working the controls when it occurred and I was outside in dark soil so I didn't notice the oil right away until my other movements stopped and I killed the pump immediately when that happened knowing I was losing oil. If this is going to happen again if I fix them and I can only use them in a dirt free area and have to worry about them binding and bursting a line if I use them then they aren't worth fixing. I'm just a little mad right now of course I want them working properly. I just don't feel like I did anything wrong for anything to break. I mean if I can't use the tracks in dirt what's the point. Thanks Thomas. I'll figure something out and PM if I need help/advice. Regards, Frank |
