Buying Advice Chinese backhoe manufacturer

[blackd]

Does anyone have experience with Weifang Yijia Imp. & Exp. Co., Ltd. and their attachments? I am currently negotiating for a 3 pt backhoe, and wonder if anyone knows about quality and problems with payment?

Another question: is there US duty and tariffs due on these attachments when entering the US?

Any help is appreciated.

What model backhoe are you considering?

I'm looking at this LW-6 http://web.mail.comcast.net/service/home/~/LW-6.jpg?auth=co&loc=en_US&id=698740&part=2

That link is dead. Have you tried China Best? They deliver to your door, almost.

Got any pics? The LW-6 can have a few suttle differences, and all are not created equally. Knowing what I know now, I would either want to lay eyes on the one I was purchasing, or get good current pics of, and assurances that they are of the model that will be delivered. Of particular importance is the boom swing pivots. Each pivot needs to be comprised of 3 plates, 2 on one side of the pivot, sandwiching the other plate with the pin passing thru the three plates. If it dosn't have 3 plates per pivot pin, the pins will not stay square and the holes in the plates will quickly wear and the boom will flop all over the place when you try and swing... The thrust bearings must also be placed properly in this mix so the heavy boom swings smoothly. Good pics can show this fairly easilly...

FWIW, I had a LW-6. Kept blowing piston cup seals, and didn't have dual acting swing cylinders - very poor swing power. Sold it and bought a LiTW. Great back hoe, used it about 20 hours, and bought an excavator which was better for my needs. Too bad you don't live closer, I'd make you a great deal on my LiTW (and it has a thumb).

Bob, I thought the same thing re: deals and distance.

RonMar, thanks for the good advice. Can you tell me more about the issue.

Here is another pic of the loader.

Unless they have changed you will need to install a return line filter, especially if you plan on running it on the tractor hydraulics.

I did a lot of modifications to my BH to get it the way it should have been. I don't feel too bad about this as I received a screaming deal on it, and I enjoy a good engineering project every now and then At any rate, here is a thread I started about those mods.

The very first pic is of the area I am refering to, the boom pivot. IF you zoom in, you will see a white zip-tie around the lower boom side plate. That was the only plate there when I got it, with the tractor side plate above it and a thrust bearing sandwiched in between. That boom weighs hundreds of pounds and can have thousands of pounds of force applied to that top pin when digging. It didn't take long for the pin to start to angle as the forces wore unevenly on those 2 plates. This caused the boom to buck and jump when swung. I added the second boom side plate, made slightly larger pins and trued the holes. Now it swings smoothly without bucking. I did this top and bottom. Knowing what I know now I would not buy one without this type of pivot structure. Got a tractor dealer near you? IF you go and look at the BH's they sell, you will be able to look closely at the pivot area and will be able to see what I am talking about, as most everyone does it this correct way, but some of the chinese do not. That pic you just posted does not show the pivot areas...

The pic does show that the BH does NOT have an onboard tank, and that it appears to connect directly to a tractor's hydraulic system. WHat type tractor are you planning to attach this BH to? A BH being all hydraulic really works the fluid, and generates a LOT of hydraulic fluid heat. Most tractor systems do not have a very large volume of fluid onboard as they typically only feed steering and loader/3PH operations. Those operations are also only part time so they do not generate much heat. Because of this most tractor hydraulic system are not prepared to dissipate the heat generated by a BH at work. Most of these small BH's have an onboard tank(5 gal) and a separate hydraulic pump that is driven by the PTO. The tank gives volume so it takes longer to heat up to fluid damaging temps and the tank surface area is large to allow it to more readilly dissipate heat...

Thanks, RonMar. As I understand it, originally your BH had a single plate on the top swivel attachment? You added a 2nd plate and aligned the holes and made a longer & larger pin to attach the boom?

I am planning on attaching to my MF GC2400. I want a self contained 3 Pt unit driven off PTO. If I begin to use it for anything other than the light trenching planned, I will consider fabbing a sub-frame.
