Excavator Maintenance - First time changing hydraulic fluid (S1E24) 

So for bleeding you only have to loosen the filler cap? On mine it says to loosen the 6mm Allen key on the pump but the instructions are not clear -- with or without engine on... Anyone? Apparently it can be serious (destroy pump) if something called 'cavitation occurs.

"It didn't say how to pressurize the tank." Ditto here.

Exclent point about prepositional error (rather lacuna). Checked mine: final instruction: "5. Tighten the vent plug ..then pressurize." What they call the vent plug I call the filler, for obvious reasons. The " pressurization posture" shows the boom pulled upright towards the cab area, the stick folded back into the boom, and the bucket curled up. Looks rather like a crane on one leg doing some mating ritual...

I just bought a used PC60-7 and am also a Japan traveler. It looks like you're in Japan which is a pleasant surprise as I hunt for videos on changing hydraulic lines index the excavator.

Great vid thanks for sharing

Jon normally you would change the filter element at the same time you change the fluid.

What is that beast of a superstore you went to? I don't think we have anything like that around here in Nagasaki!

I own a Midi Komatsu ex,,I feel your pain!!! When I bought mine and my dozer, I went thru and changed EVERYTHING!!! You just never know who had it or what they did to it.. You will learn tons doing it yourself... Have lots of 5 gal buckets on the ready.. Good vid!

Hello or I guess I should say konnichiwa? RU-vid sent me here when I search how to change the top track roller on my mini excavator I just bought a Takeuchi tb235. Our lives are surprisingly parallel haha I'm doing a lot of the same kind of work trying to fix up my 40-acre piece in North Florida which is currently being utilized as a hunting camp as I I'm still working and living Fort Lauderdale but someday I hope to retire on my land.. anyhow, your channel caught my eye because you are in Japan. do you mind we asking why you're there? I've always had an interest in Japan and it's definitely on my bucket list to go there. You speak Japanese? Sorry for so many questions😅

Nope, doesn't look clean - looks like engine oil. Do you need to open the filler cap to let air in to avoid the gloops?

How many hours on that machine? That oil didn't look as though it had ever been changed. May also be worth investing in new suction and return hydraulic filters. Preventative maintenance is absolute key with any field equipment. You'll develop a love hate relationship with grease. Lol. Keep up the good work! 😁

You: "How am I supposed to drain out of that?? Come on, Komatsu!! Me: "How am I supposed to drain out of that?? Come on, Takeuchi!! I'll watch, and see whose is worse (I have TB016).

Hello. Great video. I have a PC 20 and I cannot figure out how to raise the cab. I know the canopy goes up with it but there are so many bolts back there and it’s not budging. I have a small leak underneath that I need to get to to see what’s going on. It shouldn’t be this hard. Thanks for any help.

I purchased a used '08 Komatsu PC35 last fall for my property. Needless to say, i have found out about owning a piece of construction equipment and the costs involved in maintaining them. I changed a few O-rings on the pump within the first hour of operation. This is when i was introduced to how expensive Komatsu replacement parts are and how proprietary the manufacturer is. Twenty litres of H46 hydraulic fluid, a new replacement filter and three O-rings was over $300 dollars. I changed the rings myself, as it was pretty straight forward, as was changing the oil. I never did try to bleed the system of air following the oil change. Everything seems to be okay, although, after using the machine for a certain amount of time, I find the machine sluggish and not as responsive as it is when the machine is cold and the oil still thick. I have almost 4000 hours on it, so I'm not sure what work was done on this by the previous owner, as the leaks from the pump were caused by the replacement of generic O-rings. As i stated earlier, this is a very proprietary company and the use of generic replacement parts is out of the question. You can't even find replacement parts on line, which is why they are so expensive. They have you over a barrel. At any rate, its a nice piece of equipment to have instead of having to call a contractor and be at their mercy for showing up or over charging you. Cheers!
