What a good design. You lucked out on that one.

Thank you for sharing 👍👍👍👍

Nice repair 👍 man that machine is ultra compact, it’s amazing how well all lines fit under those covers.

Do you happen to have any pictures or video of the mounting plate removed?  My rotation joint is leaking and I'm trying to decide whether i want to remove the engine to have enough room to work.  Awesome video thanks for posting!

My Yanmar has the same problem, your video is very helpfull. Many thanks.

Add another key on opposite site soyou have 2x keys

I have excavator swing fine when the hoe empty above ground in the air, when I try to move dirt on ground weak no power can't move dirt?
I don't know why any idea ?

Where did you find the new key?

I have a problem with the swing motor on the Chinese mini-excavator, which means that when the dome turns in a certain position, it squeaks, I feel as if it is grinding on some sheet metal. What could be the problem?

Do you know where we can find Parts the swivel gear motor the actual gear itself fell off of my pump/motor. I’m not having luck finding it. Would you happen to know where I can find it or what part number it is any help would be greatly appreciated.

I have doubt don't you grease the swing motor pinion regularly?

Where did you get your paint

Only 1700 hours😂

Hydraulic motors already have some play when new or when used the Drive Link Bar is splined and has play on both ends drivelink is inside hydraulic motor

Did you really put that together without covering everything in grease? Dry metal on metal will eat those gears up quickly.

What's that you're putting on the threads? loctite? What strength?

why even have a removable key there? it should just be one with the shaft

Check out my other videos and the video called repairs on mini excavator are finished to see the major improvement with this repair
