My Mruder (bruder cat320 something look alike)

[cdm]

Performed leak test, the plunger screws leaked but because i left them too lose. corrected that and had no further issues at 14 bar. will test more later. just to make sure.

i got my pulleys and timing belt but i was thinking.. if i connect it directly, it might put too much sideways pressure on the pump shaft, wear it unevenly and create a leak, essentially destroying the pump. since there is no bearing present, i doubt it has any lateral support built in. i will need some tension on the belt to avoid it jumping and vibrating, but i fear even the slightest pull will be enough to cause damage.

to correct this i would have to build a rig and suspend the pulley on bearings and use the stock connector - basically the vario design but with the motor on the side, not on top) this further complicates the task and takes yet more mm off my space i wanted to leave up front. 3mm plates x2 = 6mm, 3mm w bearing + 2.5mm w bearing = 11.5mm wasted space. and thats before the pulley and coupler.

i am only trying to do this for better aesthetics. not sure it is worth pursuing, might just go back to my original plan of having it as a short slope/high step mining canopy
