<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
<\/p>\n
The other day, I did a little work on the jack cylinder because it was covered in scratches and leaking hydraulic fluid.<\/p>\n
It\u2019s the jack part of the drilling machine\u2014you know, the part that gets buried in the ground or hits something...<\/p>\n
<\/p>\n
First of all, the cylinder is a super important part, so you shouldn't hit it with stuff, right? lol<\/p>\n

<\/p>\n
Cylinders serve as the \u201ctendons\u201d of construction machinery.<\/p>\n
If a person's tendon is severed, they won't be able to bend their hand either.<\/p>\n
This is a very important part.<\/p>\n
<\/p>\n
These are the areas you should always protect when working.<\/p>\n
Even so, scratches can sometimes occur from flying stones or the like.<\/p>\n
If a small scratch causes a slight bump, please polish it with an oilstone.<\/p>\n

<\/p>\n
Polish the surface while applying oil with an oil stone.<\/p>\n
Kind of like deburring.<\/p>\n
As for the large protrusion that still won\u2019t come off, I guess I\u2019ll just have to remake it, but this time I tried shaving off a layer with a lathe lol<\/p>\n
<\/p>\n
Since machining a cylinder on a lathe is a bit of an unusual process, I can't really recommend it.<\/p>\n
I bet the manufacturer would say, \u201cNo way!\u201d lol<\/p>\n

<\/p>\n
The first, battered one looks a little neater now.<\/p>\n
The amount removed is approximately 0.04 mm to 0.06 mm.<\/p>\n
Still, the surface turned out nice lol<\/p>\n
The burrs came off cleanly, too\u2014it looks great.<\/p>\n

<\/p>\n
I installed it for now, and so far there doesn't seem to be any hot water leak.<\/p>\n
<\/p>\n
It may seem like a small thing, but let's use our heads and think things through before spending money.<\/p>\n
If it doesn't work out, just buy it.<\/p>\n
I think the results of that experiment will be a valuable experience either way.<\/p>\n
So let's practice coming up with ideas and using our brains!<\/p>\n
<\/p>\n
See you later.<\/p>","protected":false},"excerpt":{"rendered":"
