if it's very hard to release hyd nut, what is max hyd pressure ? on the instruction working pressure (dismantling condition) is 1400~1650 bar. It's 6S60MC-C8.2.

The oil return pipe - we use it to close exhaust valve by high pressure oil, instead of using high pressure air, right?

this is a very informative video. However, we have a similar engine (7k60MC-S) but the cylinder cover comes with bushing for the fuel injector but from this video i could not see any bushing for the fuel injector. we have been trying to remove the said bushing but its almost impossible. please any advise?

I think once u overhaul a cylinder head u should check the condition of liner or calibrate the liner,water connection between head & liner not shown.pressure testing of head is not done. Anyway marvelous video

5:00 How can pressure be this much high? 1500 bar!!
@chetanpatni1519 Жыл бұрын
It used to be 1700 bars on our ship. Hydraulic pump helps in building that pressure up. Without that it is impossible to loosen or completely tighten the hydraulic bolts.

I did notice when he was using the hydraulic bolt equipment he was loosening the hydraulic bolt removers by turning them hand on hose connection point which to me seems like a bad habit practice longterm in respect of longevity use life of the tool better to remove a tool correctly to maximise the life use of it

I'm finding it difficult to understand how those little hydraulic nut removers can apply sufficient torque with out having a firm anchor. They seem to just sit on top of the studs and twist those nuts off with ease.
@girliepadasas34017 жыл бұрын
videoclipits those small hydraulic nut remover simply stretch the stud against the the cylinder cover thus freeing the nut so it could turn the nut with minimal effort. The video somehow miss 1 important thing on removing the nut, the hydraulic tool must be loosen by at least 3/4 turn so that when you release the hydraulic pressure on it will not trap the tool when the stretch stud return to its original length. One thing I noticed was it uses 1500 bar pressure in removing the nut which is almost double to the one I usually work with or maybe it is because they used new type of stud material on the video

What most idiots here don’t seem to understand. This is supposed to be a supplementary instruction video which does not substitute or replace the Manual. As a side note, air guns are great for gulling of threads and destroyed fasteners. A professional knows when and when not to use those.

You are a moron. That is O-ring grease which will still be there next time the cylinder head is dismantled. It will not burn away. And only a true idiot would use copper paste on O-rings. I hope you never work as a mechanic. 😊
