[1:14,5] Bruder Cat 320 conversion

Hi,
I need help with pipes. Piston in my cyliders will be 13mm. If I use this pump (Leimbach) Hydraulikpumpen-Einheit mit 450 cm³ / min. u. Tank 12 V Bestell-Nr. H0104 is this pipe then ok Schlauch 3/1,5mm Bestell-Nr. H052?

Thanks!

Or should I use this pipe Schaluch 4/2,5mm Bestell-Nr. H058

H052 is ok, but:

4/2,5 is far better, as you have a much lower resistance!

If you can use the M4 tube connectors it would be great, as the M3 cannot have 2,5 inner diameter

Leimbach is offering PU pipes, which are soft. So you can have comarapble tiny corners, but you are near/over the specification of the pipes.
Better would be PA pipe, which is not so soft, is specified for much higher pressures (25-50bar), but you have to use bigger radiuses.

Yours,
Martin

New pictures. Bucket is ready and boom also.

Looks amazing Ari. I will take some time to collect all the bits and pieces and then I will start doing my conversion. Would be helpful if you could share more details about the parts you bought.
Keep up the nice work!

Cylinders are almost ready. Piping is the next step :-)

And it is ready

looks real great

awesome!

After some problems with Leimbach pump I made decision and changed pump to Premacon pump. Oil temperature was too high with Leimbach and I lost the pressure quite fast.

With new Premacon pump I have bigger oil tank, bigger flow even with low rpm and more pressure.
Here is new video. The stick config was wrong and thats why I have small problems to use my Cat (I upgraded my Turnigy 9x firmware ).

Pressure is now 20 bar, pump is running half speed when using one movement, with two in video pump is running max speen ( after taking video I changed configuration of my mixing and now with two simultaneous movement pump is runnin 75% of max Speed)
