Importing and modifying a new mini excavator from China

[scutty]

Added a 15GPM filter, grease fitting to thumb mount and cut and re-welded thumb bracket. Really dumb design not allowing the thumb to go further back in the up open position. I was able to get about 6 more inches which helps for fully extended digging. Also added square stock between the thumb to keep it from getting mangled again hopefully. 13 hours on the new machine without issue. It does however really heat the oil up over 180F with a lot of dozing even with a cooler and fan.

Mine came with a fan/oil cooler too, it wasn’t enough. I added a 7” fan, this helped, but still too much heat in my opinion in the engine compartment. I added an exhaust extension, as the muffler exhaust was just pointed to the engine cover opening. I think this helped too, but it’s not shedding heat like I’d like it to. Maybe a muffler that is outside of the engine compartment…?

My fan setup is factory pulling then auxiliary one I added pushing out, lots of heat blowing out. Just curious if others with two fans run them as I have. I should probably get a thermometer and try some real world testing.

I wrapped my muffler with ceramic then aluminized wrap which helped keep the heat from the exhaust down. Digging it seemed like my hydro oil was only hitting 120 when it was in the 80s out, so not bad until you work the drive motors a lot.

Mine came with an exhaust heat cover/blanket, but I really don’t understand why no exhaust extension.

Mine did come with the extension screwed into the exhaust shield. At least they are making improvements.

on the L12 where the hoses come out of the boom, really sharp edges. took die grinder & rounded them off. replaced damaged hose protector.
almost ready to start using this dang thing.

Well I guess I did it again, Anyone know the Origins of Machpro Branded Chinese Hoes?

Well I guess I did it again...

Congrats. So, maybe 4 1/2 metric tons? Maybe take it by the truck scales when headed home with it.

Can't wait til you open it up to see how its made....
