Can we see a video of it working

[pumptech]

nice pics ,she's a digging:D

Nice pictures

Very nice just love seeing these machines working in some good old dirt and such

Hello! new member. Nice machine!

[calum_scania]

Thank you guys! :)

This is my first hydraulic machine, i'm slowly ordering up new parts to improve the way it performs and looks

Can anyone advise on my hydraulic pump? I'm looking to upgrade it to speed the movements up..

[thercfreak2012]

My friend said use the same pump from leimbach and order extra rubber couplings with the pump

If you wanna keep the same pump, you can change it to brushless motor from Leimbach and that will make it more smooth. You also can up the bars ( or psi ) on the pump and that will make it seem faster ( I think 18bar is max ), but that also puts tons of wear on the components. If you want a new pump you can use a JUNG setup if you can find one, only thing is you have to change the layout and I'm not sure you can fit all of it on there. I have the same pump on my 944 and it's awesome. There are more powerful pumps out there but only fit larger machines with more space.

Currently in the process of buying a Martin Kampfshoff pump which i believe has a jung motor fitted.

If it wears out the cylinders or valves i will just upgrade them to better spec items ;)

I am also looking for a pressure gauge and fittings in the UK?

[thercfreak2012]

Hey Ross u will not find a pressure gauge and fittings in the uk especially where you live ?

[Lil Giants]

Judging from the pics, this looks like an old machine... early 2000's?

It probably has 1.5mm ID hose & fittings...

Just to go to 2mm ID plumbing speeds up the hydraulic flow dramatically with your current fitted Leimbach pump... similar to this one.

The age of the machine I am unsure of? As it was second hand to me..

I did think about changing the hose size too, but I was unsure if it make that much difference? It was horribly slow before, so I changed the pressure on the pump which has made it better now.

I decided to change the pump as the Leimbach would be working too hard all the time to keep everything moving. The machine works very well, the electronics will be replaced and modified as the pump runs continuously and the track control takes up a huge amount of space

Out again for some more digging in a new location

[thercfreak2012]

Nice picture quality

[calum_scania]

Can anybody tell me where I can get a replacement motor for my drive?

[thercfreak2012]

Check the leimbach website

Nice 922 Calum_scania i like that machine because of its size.

Joe, the thread size on the 1.5mm id and 2mm id fittings are the same? What is a good source for the 2mm id fittings? Thanks.

[Lil Giants]

I don't believe so Scott. A great source is the link that avel posted above, they speak great English & ship fast to North America.

If you look at the pages in Hydraulic -> Leimbach -> Spare Parts on pg 1 & 2, you'll see the difference in thread size vs straight nipple/hose size... it varies again when using a 90* fitting.

Thanks, i thought you had drill and tap the cylinders to increase the fitting size but, didn't know for sure.

Nice video!! I like how you put in different angles of view.

Thank you, a short video with plenty of angles

Just an Idea, RC4WD has 2mm Hose, this may work, but Joe would Know better than I.

[calum_scania]

Hello everyone I'm trying to do this on my MC20, Its to contol functions on a digger, normal mode for digging and the sliders control the tracks. Then a switch setup to change the right stick to control the tracks. I have set up 6 mixes which seem to be working, but using the ELE towards you and AIR to the right is still moving the servo's I don't want to move (these work fine on the other direction) I there something simple I've done wrong?

Here's a video on a Spektrum radio which I'm trying to achieve

Many thanks Calum

[ptebbe]

Calum-
What you are trying to achieve is entirely do-able on your DX10. You simply have not configured your mixes completely right.

This requires 2 mixes for each stick direction, both turned on by the switch. The first mix has to completely negate the original control commands...set up the mix to be completely opposite of the original control. You've manage to set up your mix correctly for up and left, but not down and right. A simple tweak of the mix parameters will solve this.
This is my cancelling mix: Ele==>Ele -100% -100% and Ail==>Ail -100,-100

The second mix then adds the control to the stick that goes to the track drive.

(For some reason that I do not entirely understand, I had to set mine up such that the original Ele and Ail channels controlled the tracks, then the mixes over-rode it and mixed control to the dig-arm. Otherwise the drive motors would not stop even when the sticks were neutral.)
hope this helps.
Paul

[calum_scania]

I've just sorted this tonight, I was a combination of 2 servo's needing slightly adjusted and having the values set to 150% instead of the correct 100%
