Hello people this is my new machine out for some digging yesterday

[thercfreak2012]

Can we see a video of it working

[pumptech]

nice pics ,she's a digging

[thercfreak2012]

Nice pictures

[headers]

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..

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?

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

[thercfreak2012]

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

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

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.

Out again for some more digging in a new location









Then the driver had a quick tea break

[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

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.
