Several commenters, here, seem to believe the fans are 12" fans. They are 7 inch fans. I have almost the same machine, and a 12" fan would never fit in those areas. I can guarantee that those are 7 inch fans. I hope this is helpful information.
My excavator, ("VOTE" Brand), has the pull start cord assy removed and a piece of duct going tight to the side panel, drawing fresh air by the engine flywheel fan/impeller allowing for positive air flow into and out of the engine compartment. Thanks for making this video. Good luck to you!
Just wanted to say "THANK YOU" as I did this to mine as well with fusible (15a) inline link. Also added aluminum heat shielding around the exhaust, gas tank, and full sheet under the seat. Changed all new American zerks also. Works Great.
Nice video. One recommendation…get that plastic off your seat. Took mine off right after buying it and the seat bottom was covered in mold and rust. Thanks for the video!
just posted a video to my channel of me testing one of these mini excavators with a TMK 150 tree sheer. I was mind blown how well it handled 5-6" diameter trees!
I'm curious if your battery is holding up? I believe the charging circuit is only 10 amp on that engine, and the fans draw about 6.7 amps each, so theoretically running both would drain the battery over time.
Frank. You are right. With most cooling systems on almost everything, the goal is to extract or pull the heat from the area. But any air movement I'm sure is a definite upgrade.
@@jaybrown651 Nah. With an air cooled engine, you want to get cold high velocity air to the engine, sucking out the warm air is way less effective and recirculates a lot of cold air. Ever tried to inhale the air over a hot beverage to cool it down? Nah, because it doesn't work. Same thing with a hair dryer. You can blow a piece of paper around from 6ft away with the high velocity air, but if you try to suck anything from more than a few inches, you're out of luck.
Would it not work better with one fan pulling and the other pushing to create a flow rather than two fans pushing against each other and negating flow? The fact that you removed the back panel shows that this does not work as well as hoped. Since they are bi-directional fans it would be an easy experiment.
I'd say the grate on the back of the cover has enough holes that the fans aren't really going to be fighting each other. If these two fans were covering the only grates in the machine, one puller and one pusher would certainly be better. In this case, it probably doesn't matter and it'll prevent the fans themselves from being completely heat soaked.
Amazon sells a 200 watt flexible solar panel (100 watt at harborfreight) for $80 that could either keep the battery charged or power another fan, and the panel fits perfectly on top of the sun canopy.
Thanks to our environmental extremists, the Briggs and Stratton is the only motor to pass emissions unless you want to get the Kubota diesel which doubles the price.
@@dalethornton1113 I kept contacting different eBay sellers that indicated the Vietnam engine Kopu KD192F engine in their listing description, but when asked about the engine they all edited their auctions to show it was a B&S. So the EPA change must have just occurred. Sucks damn it. I'm waiting for a delivery on one from the AGT sellers in Chicago. Watched many videos here that had only positive things give the cost. Only negatives I found were from dealers that were pushing their branded product.
Yes most US buyers are now getting the Briggs gas engine, cuz the Koop or ChangChai 1-cyl Diesels are not EPA- or CARB-compliant. In the latter case, the main flywheel fan is ducted to the outside to bring in cool air. Most of the makers have not bothered doing this with the gas engines. I did for mine when I bought it 5y ago from China and installed my own gas engine. If you use an internet search engine, you will find pix of how I did it. Utube is great for vids (see mine for the XN08), but does not allow commenters to respond with pix. The automotive electric fans do move a lot of air, but some of the gas engines, like my Duromax 420, do not put out enough current to power them. The B&S alternator puts out more current.
Great Video. The manufacturer should add at least 1 fan to those small excavator. 🎉

Great job! Thanks for sharing. Looking to buy one of these minis so the upgrade is nice to know.
did the exact same thing to my QH12.. both pulling air in, works fantastic

once you dial them in they are solid machines
Thank you for posting this. May I ask what amperage the fuse is?
Good Job, friend, It is nice machines. I purchased one about a month ago from Denny. I had mine shipped down to TX. It works perfect the work I do.
Great idea. Where did you buy the fans. I recently got an excavator very similar to yours and would like to do the same thing.
those are standard radiator car fan 12v i believe, you can buy those in any car parts store
Nice video. One recommendation…get that plastic off your seat. Took mine off right after buying it and the seat bottom was covered in mold and rust. Thanks for the video!
Nice clean install !!!
Where did you get the fans? And what size are they 12inch ?
Nice they moved the hydraulic tank forward now. H12 it's where your cup holder is. I've found with one fan it pushes a lot of heat up under your feet.
Wouldnt they be hot all the time if it was connected to the starter
Thanks for the video. I am going to wire mine up with the harness for a LED lightning system with a switch.
No relay?

Iv had no issues with charging, it appears to be keeping up with the demand
Has that worked okay having a fan on each side blowing on the motor, Any issues since you have done? Also, what gauge wiring did you use? Thanks
How are the fans working out blowing air into the engine compartment.
Probably trying to create positive pressure
they work great, provides a constant breeze over the engine
Are they both flowing air the same direction
yes both blowing air into the engine bay
What size fans you run?
7 inch 12v off amazon
Are these 12 inch fans? Wondering what is the largest size that fits to maximize the effect.
Use 7inch 8:05
If both fans are blowing out of the machine it would would seem to be most efficient to me.

@@GarrettGalloway👌 that back has plenty of air flow gap

Thanks for the video
so did it make it cooler
Thanks for this.
Absolutely
This is what my QH12 looks like, but it's Orange.
These only have petrol engines in America, for the rest of the world they are diesel and don't need additional cooling

Couldn't follow how you wired fans together and went to fast. Can you go slower and steps better?
No link in the description to the fans.😡👎 That's why you got a Dislike.
Can you do anything by yourself?
