Importing and modifying a new mini excavator from China

[dfkrug]

I am not sure of the Brand of the Knock Off yet, my Stand On and Mini Wheel loader had the 739cc Rato.

Chongqing Rato V-twin gas engines seem to stop at the R670, a copy of the Honda GX670. I think they are the maker of the Predator 670. To get over 700cc in a gas twin, you likely have to get a Kawasaki, Kohler, or some other Chinese engine.

Rato seems to have a good rep, and the several new and used ones I have owned were good. Numerous Chinese GX clone makers still do not put their names on their product. I have one of those (420cc) and it is not as good.

Rato top out at 999cc

Both my SDLOOL380 and my Traner TR45 had the 739cc Versions

Interesting. The Rato HQ website does not list the R740D or the larger one, either. Only Rato-Europe does. And eBay lists the R740D for sale, from Italy ($2200).

Gasoline engine Chongqing RATO Holding Group Co. Ltd.

First I have heard of them.

Yes, I have seen them, 739cc anyways. Rated @23HP. This latest machine's tag states 25hp but no Brand Name on the Tag.

Guess I will find out in 3 Sleeps, 1453km each way. I am only worried about my U Haul trailer being there ready

Picked up the same model as you. So far I like it but I have the same issues with the thumb. It looks to me like they just slapped a hydraulic cylinder onto a mechanical thumb without any consideration of how far it would go back. Do you have any pictures of the mod you did to the thumb to make it retract more.

Thank you. I'll have to see if I can do this!

Have you picked up the new machine? What do you think about it, and how are the pilot controls?

wrapped muffler with motorcycle muffler packing & muffler tape. it melted and the tape burned. measured temp with heat gun, it was over
900 deg f. what are you all using for this? thinking about trying carbon fiber welding blanket.

I just bought exhaust pipe wrap on the internet. No tape, just metal straps to hold it on. It served fine until wood rats chewed some of it off. Since then, I just added some fiberglass insulation and some more steel wire to hold it on. I only put it on the pipe between the manifold and muffler. My muffler is outside the house.

Yes, I have it Home.

Pilot Controls are very "Light" but very smooth, I will have to get use to them.

The machine is Big compared to my 1.2T FF Industry. Very simple layout. had to adjust the Walking Levers to make them Even.

Here is the Corker. So I got back Tuesday, Slept, Worked on it Wednesday. Loaded it, brought it Home.

Went to the Cabin Thursday, and someone broke into my Truck, smashing the Window

Stealing the Keys left in the Cup Holder. So now I am screwed, Door, Machine, Fuel, Motor Cover, and Hydraulic Fill. All different keys.

Here it is. On it's way home. 2900km (1800 Mile) round trip

Sorry to hear of the break-in. DId it happen in a rural area?

As for the keys, I guess you now will replace all locks with matching set, no?

Nice to hear that hyd flows seem to be matched to your engine. Do you run at a full 3600RPM? Do the wheel motors feature piston drives, planetary gears, and brakes?

It happened at the Boat Launch (rural Crown Land) The same Launch I have used for 30 years, first episode of this.

The motor doesn't need to rev that high, without a Tach, my guess is 2000-2300RPM, so Awesome that way, but I have yet to work it. Full extension of the Stick Cylinder will stall the Engine under those RPMs

I haven't had much "Travel Time", but Unloading off the trailer my guess is "Yes" to Brakes

Yes, Keyed alike is the way to go, I just have to find the Cylinders to match. I think I will bust into the Cab, and remove the Lock Cylinder in the Door, while in there, I will grab the Master Switch Key.

As for the Ignition, I will just buy a Switch off of Amazon, once I can figure out the Plug

That RPM is a little low, even for the V-twin. 2500-2800 would probably be optimum. It seems they may have set your main system RV correctly if you can stall at that speed. But don't forget that these engines need to be warmed up to run well. Still check the pressures.

Take a snap of the wheel motor from outside the tracks, and it will be obvious if you have a cover and a gearbox there. You may want to change the wheel fluid, too. As you would for the whole machine.

A locksmith is likely to be cheaper then "breaking" in.

Breaking was a little overboard. I think I can slide the window open

Update!, Police have found 1 set of Keys, My Dad's Zippo (sentimental value) and Daughter's Truck Keys!

Just need a New Ignition Key and Window now!

Nice depth/volume. I just don't understand why China has not improved them.

Have you had a chance to use the new MP46 enough to comment on how it performs relative to the smaller 1ish ton machines?

Awaiting an Ignition Switch due to arrive today. So still waiting. Not sure if I will keep it or not, "Bigger" isn't always better at the Cabin where I have the most use for it. However the Swing Boom, and Pilot Controls, might make up for the Size.

I did manage another 20 hours on the FF12 this weekend. The Cabin is getting to be like a Park. Raking under Trees, Crushing up Deadfall, Piling a Brush Pile to Burn once Snow Flies.

Grass Seeded (I know it's late). Drained, Ditched, even some Graveled Trails in the bush.
