I looked carefully at this video....very elegant design. Great work

Thanks for putting in the work. When I get my H12 I will get the kit from you.

Seems like a great kit and a good price 👍 pretty awesome. I think these coolers will definitely improve the hydraulic system by keeping the oil from overheating, seals, motors and pump will definitely last a lot longer. 😊👍

Let's go with the h15 kit.

diggit em15 are you gonna do a kit for them

Nice job 🏆🏆👍

I have enjoyed your videos and knowledge on the AGT h12 mini excavator. I have done a test with two fans 50° temperature oil temperature after 3 hours 155°.

your videos are fantastic for these machines. do you have a list of the pump / tank fitting sizes? I got my H12 AGT a month at an auction and have been waiting to use it much until I get the mods done I want.

How about inverting the boom cylinder to reroute the hoses out of direct fire and also fabing a shield / guard for the piston shaft.

Agree with all other comments concerning performance data on this kit. We need some numbers.

I went ahead and purchased the H12 over the QH12 per your last video. Ordered it from Amazon for $5,400. Was looking for a cooler and filter. Delivery says around three weeks, so mid Feb. Was looking into an oil cooler and filter, so this is just in time.

It appears there is a ton of crossover on the kits

Great video I own a H12 debating whether or not it needs a cooler Have you tested your cooler setup to show how much it decreases temp?

Do you offer just the filter option with required hoses? I dont run the machine that long and never had cooling issues

Very impressive, sir. Following for an ff12 hydraulic cooler kit. Or just a part number for the cooler and fittings

Hey my friend. Kit is sold out, any idea how long until more are on the site ? Thank you!

Can someone explain where the filter line goes from the back after entering the filter housing. I can’t tell how it routes after the filter

Would it be possible to put a bigger motor and bigger hydraulic pump on a agt l12?

do you have a filer kit for agt lh12r they already have cooler no filter

Could you do a video of the installation of this kit?

I just bought the h12 kit for my QH12R. Will this kit fit or do I need to wait for the QH12 kit?

When are you getting more in stock?

Very interesting. Would this Fit a QH12R. Slightly different layout.

Is the QH12 the same as the H12, or would this not work?

Wonder if it’ll fit the H15. Looks like the same hydraulic system, not sure about the size of hose though.

Your return line fittings take a 27mm wrench? Hose size of return is 5/8 100R1?

Two questions: 1- how many amps does the fan draw? 2-Is the fan pulling air in or blowing air outside? I like how you have it arranged, its a very clean set up and looks easy to service and install, better than others I have seen posted on KZread.

Fans draw 3.4amps each while running at speed. I had them blowing into the engine compartment

Please let me know if you plan a kit for the FF12, or similar, with factory installed filter. I would be interested, thanks!

Thanks for the channel. I have a Chinese mini skid. And I think it needs a new hydraulic pump. Do you know where you can acquire these? It has 3 hours on the machine. It worked great going off the trailer and then quit. Hydraulic pressure is 700.

Note: When I drained the hydraulic tank to install the filter I fished the bottom with a magnet and came up with some metal debris. Some of it looks like shavings from drilling. Be sure to check and clean your tank.

Not sure why everyone is going crazy for hydraulic oil coolers, unless your running it 10 hours a day 7 days a week then maybe it’s feasible other that that the oil doesn’t get that hot. The filter is about all you’ll need, add an oil cooler and filter to the engine. It’s oil is well above 220 degrees, yea I know it’s splashed lubricated but you can add a pump, oil cooler and filter and pipe the return back into the valve cover to help cool the head.

The hydraulic oil in this mini excavator easily gets over 185 degrees on a normal spring or fall day, and at oil temp over 185 degrees the fluid life is 12.5% of what it is at 140 degrees.

@@Inwetrust-qy2ly Viscosity is irrelevant. If you overheat oil it breaks down. If you know "plenty" of machines that run high temps with factory oil you probably work for government, where the machines are beat to sh!t, ran to death, are junk internally, and sold to suckers at auction. You can run a Brigs motor on break-in oil it's whole life if you want. Sure it will still run, but cam bearings, rings, and cylinder walls will be trashed. But hey "iT sTiLl rUnS". smh
