Chinese Mini Excavator: Turntable and Slewing Bearing

[@CaptainCoucho]

I'll have to say having just purchased a new FF12 MiniEx, I've watched all your videos and am learning a ton about these things from you. I am a fabricator and you have definitely motivated me to make improvements to the hydraulic system and understand the way these things work. Bought mine to move along a retaining wall project at my house and to use at my job at an oyster farm in Maryland to install some drainage systems in our nursery. Keep the content coming and I've shared your page with several others that have Minis. I'll be sure to share my custom mods with you as I progress. Seriously...Thanks!

Great video, I have a 2 ton excavator with a small amount of play when swinging left or right. You answered my question about having a bit of slop in the gears. Guess it's something I'll have to tolerate at this price point.

[@michaeldarmochwatii7012]

I just want to thank you for your videos. I recently purchased a ff12 model excavator and your videos are the best source for maintenance and repair advice I have found anywhere!

[@kevinpetursson350]

I have a leak from the swivel motor. I've removed the 4 bolts, but I cannot get it out. Is there more holding that swivel motor in place?

[@pigthesidecardog7442]

Damn Cam! I just asked you to do this like 2 days ago. You dont mess around. Haha. Thanks man. I see you have another 20 subs since then also. Good for you, you're putting out very helpful content for a lot of people. Absolutely by far the best info out there. Thanks again.

No time to waste spreading the knowledge

[@user-lj1cu4gk7s]

How do you drain the hydraulic fluid from the tank

[@thegarageconnection]

@@user-lj1cu4gk7s sadly no nice way exists. Most people suggest a fluid evacuator

[@mmmark61]

Love your channel! You have a ton of knowledge that I'll need. I just placed my order for my H12. Thanks!

[@jamesb.armstrong5433]

For anybody buying one of these at auction, i would advise you check it out first. I went to an auction site in person wherre they had around 40 of these Chinese excavators coming up for auction. I was checking out the movement in the boom. One of them was obviously missing bushing in the boom. It had all kinds of slop in the boom compared to all the rest of them.

[@jeffbederian]

I want to know more about the Psycho that disassembled his excavator to reassemble it in a confined space.

[@johnrussell6620]

I just bought a "VOTE" machine that appears to be very different from your 2 machines. I am appreciating your presentations very much as the individual components are similar and the overall functioning / operating information is very interesting. Your presentation is very clear and concise. Thanks for making this information available. p.s. Where can I find more information about Kyles Underpinning project as I am doing the same. +New Subscriber NOW!

[@jacobwiglama2604]

Excellent. Great information.

[@Cliverichey]

Great videos, thanks! I have, what I believe to be the same mini excavator as the yellow and black one you use in your videos (mine has no labelling anywhere). It's very difficult on my machine to 'fine tune' the left and right swing - for example when trying to line up the pins on a quick connect. The reason for this is that the small fitting on the turntable deck does not appear to fit tightly and is a welded-on stub that fits in a notch. On mine this setup is easy to see as it's centered in the engine compartment roughly between the operator's feet. The play at the fitting is about 3/16" which equates to around a foot at the bucket when fully extended. Are these machines manufactured this way or is mine damaged?

[@briannettles786]

I’d like to see some mods like upgrading pumps drive motors ect

[@David-xd1pn]

Great video and explanation. My question is, the motor that you pulled, was it held down with Allen cap bolts? On my QH12 it's almost impossible to properly torque that motor down.

[@thegarageconnection]

Mine has normal bolts, but did require a wobble socket to tighten

[@David-xd1pn]

I think I'll replace them. Thank you for your response.

[@MrTombo-gg4bq]

Yes mine has allen head bolts and when I realized excessive slop I discovered all the bolts were loose. Had to use a allen socket in a box end wrench to tighten. Still couldn't get it as tight I'd of liked to.

[@user-lj1cu4gk7s]

Thank you that’s what I thought

[@briren96]

Thanks for the great videos! What is the procedure for adding grease for this if you can't see when grease has come out the other end of the hoses?

[@MilestoneVids]

It takes a lot of grease... 1/2 kg. Pump like 20 pumps in each nipple and rotate machine 1/8 turn then repeat until 360° reached.

[@backdoormanintheend]

Nice!

[@RonnieJohnson-vi6gi]

I have a ht10 high top 10. I need the gear for the turntable that go on the pump motor can you help me get one

[@337aii]

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?

[@noone7937]

Where are the grease fittings located for bearing?

[@MilestoneVids]

2 nippes on the front of the body, next to the boom

[@mariodata4854]

Mine is brand new but has excessive rocking. I was hoping there was a way to tighten things up.

[@jamesb.armstrong5433]

Don't feel too bad. I had an AGT L12, and I had a lot of play also. I sold it and now have a Kabota. The Kabota is a very nice machine but it has play in it also. I believe that is just something you have to get used to.

[@johnshiny6283]

Good contents How do you adjust swivel or swing pressure as mine is loose and moving on slope. And wonder what is the problem? THANKS

[@MarkBean-vy9qc]

Did you say you have a manual?

[@thegarageconnection]

Available from Agrotk website free of charge

[@JC-mn6qn]

I have the new AGT DY-12C. Slightly different hydraulic tank setup with tank being built in under the seat. I'm adding a cooler and wondering if you know the correct name of the fitting type to return from valve body with the taper and O ring. I believe it's bspp but don't know the name for the o ring style. It's not orb style. Don't think I can post pics in comments

[@thegarageconnection]

It’s referred to as a DIN 24-degree fitting, and it’s a 15L DIN fitting

[@thegxpguy]

could i bother you to know how this machine was delivered to you? i just ordered mine from amazon, it specifically states i need a fork lift to unload it. im trying to figure out how im going to make that work lol

[@thegarageconnection]

I picked it up at a vendors house, but I’ve found a good post to a local Facebook group will give you someone who is willing to use their business address and forklift to unload it onto a trailer for you

[@thegxpguy]

thanks man i appreciate that! i live in poplar bluff missouri though. ill be using this to dig up a sewer main@@thegarageconnection

[@cs4222]

I have a Vicsec mini excavator. My swing gear broke. I sent it to a mechanist and he has ghosted me. He won’t send me my broken part back. How do I fix my excavator now? He won’t answer calls or texts. Any help would be appreciated.

[@thegarageconnection]

You need a whole new slewing motor probably

[@user-lj1cu4gk7s]

Would you please show a little better where the grease fittings are on the front for slew bearing

[@thegarageconnection]

They are on the front of the machine just to the side of the main boom attachment point

[@JIgginCrappie]

Is the little gear that’s on the hydro motor replaceable ?

[@thegarageconnection]

I’d imagine it is, what brand machine do you have
