Hi master for cubota kx 121 2 where is located reliv valve presure for gjystix thancu for your video

Kindly tell me. Where is main pressure testing port in pc210.for manual check.... Because our pressure switch does not work

You were not getting normal pressure in the past after adjustment. Then later in minute 20 you got the normal pressure 370. My question is was the problem because of relief valve which you replaced? Another question is if 1 relief valve is damaged it will affect pressure reading on the second relief valve because in the start both 011 & 012 was showing 330 pressure Thanks for the beautiful video

I have a 228lc-3 Komatsu and I can not get it to work right I put the two selonoides at the pump but still the engine wants to die as soon as I touch the stick to move it what could’ve .

Hello.. Is the relief valve o ring is damaged?

Pc300-7 Boom cylinder pressure check video plese send me

Hello, nice video. But I’ve got a question for you: how do you know it’s the overpressure valve that release too early / have internal leak ? It could be as well the pump wear ? My excavator is pw130 (wheeled machine but same pump than pc130) When starting cold I can reach full pressure without problem (345 bars) But if I insist at reaching 345 limit (it’s necessary when traveling on steep slopes) it will soon decrease the pressure and cannot reach 300 or less. Machine has only 4000 hours, I’m going to rebuild the pump. Already opened the main overpressure valve, but found nothing special. Pump is single on this machine. Pistons / cylinders have no wear. Distributor plate have slight wear, swash plate (variable cam) have wear at pressure areas I’m replacing it. It is possible the main valve getting hot then leaking so much ?
