How to Rebuild Hitachi Excavator Hydraulic Pump | Amazing Restoration Process of Hydraulic Pump 

Obviously a family affair with passing down of knowledge from one generation to the next. Kudos to this family for sharing this video. 🇺🇸🇺🇸👍

anyone who want to install piston pump new rotary kit should do the technique in 8:15 , this is the correct method to check whether the valve plate actually sticks to the cylinder block or not even they got it brand new. These people in video are experienced in rework piston pump, this is a good video

Perfect worker. They know not enough for first cleaning.. They spray petrol again before assembly 😊 good job

These men torque their nuts and bolts by the official backyard mechanics Armstrong method, if it don't move it's tight enough. But who am I, it works for them. 😁👍🇺🇸

Not to believe how clean hands they have.

That was a very interesting video of some very skilled work. Respect to your skills gentlemen in restoring the surface finish and tolerances.

Love his “YEET” torque setting 😂

Missed the pressure test to see if the pump works correctly.

Hi

I would expect to see micrometers, feeler gauges, new parts, new gaskets and torque wrenches in use. Followed by some actual pressure and leak-down tests. Didn't see any of those so I can only assume it's going to work maybe 15% better than before at best.

Pyjama and safety sandals are not enough. "Amazing Processes" need also throwing all parts in the dirt.

That's actually a good job. Only downside was that they didn't fully remove the old gasket before applying a new layer

на заводе видно тупые плохо сделали а эти горе инженера знают как надо лучше бы не лезли .Не знали спецов.
