Swapping a Predator 670 into a Landhero Chinese Mini Skid Loader

Рет қаралды 5,858

I blew up the motor in my Landhero Mini Skid with the Rato 739cc engine so I swapped in a Predator 670cc engine from Harbor Freight and added an electric fuel pump from Amazon. The Predator motor is almost identical to the Rato 739 and performs great. Even the wire colors off the motor are exactly the same. If I had the spacer on hand and didn’t waste a week waiting for parts I could have had this done in a day. Good luck and hopefully your motor lasts longer than mine.

Link to buy the CORRECT shaft spacer: DO NOT BUY CHEAP CHINESE ONES FROM AMAZON. THEY DONT WORK. YOU NEED THE USA MADE SPACER found here: www.ebay.com/itm/252430716490...

Hey that is my interest in the little Chinese equipment. They are small enough to run off of cheap little generic engines. Engine swap videos are cool! Subbed

The carburetor has two venturi. One isn't working correctly. It been discussed on the Facebook chinese mini skid groups.

I put a compression gauge on it and one side had low compression. Carb was cleaned and I had two inline filters in it as well. It won’t run if there’s no compression. Head gasket was blown when I pulled it apart.

rato makes the engine you pulled out and also the predator engines. step one on a new machine, change oil and filter BEFORE you work the machine. supposedly they put mineral oil in the engines to prevent rust during shipping and pass the volatility smell test going thru port inspections. it was never meant to be in there when you work the machine. i used a Briggs oil filter and no problems so far. air filters can be found at harbor freight customer service for around $10.50 and free shipping. get several, you'll need them.

Yeah I did that as soon as I got it off the trailer. Changed oil, oil filter, cleaned the whole fuel system, etc. You get what you get with the China stuff. New motor has a warranty so if it fails I just take it back for another one but so far it’s doing great. Runs better than the Rato ever did.

That’s a OHV …, the valves just needed to be adjusted. Mines did the same thing but once I adjusted the valves she ran better than the first day. Had to be a factory error.

I checked the valves. They were in spec.

I bought a landhero and it had a fuel problem. When it was ship here it had bad gas. I finally got it going after 4 fuel pumps then I installed a electric fuel pump. I also didn't like the neck on the tank. It would allow dirt into tank or when filling over flow.

Yeah I don’t think the stock fuel pumps are as powerful as they need to be. I put an hour and a half on this one today without a single hiccup. Electric fuel pump is definitely the way to go.

Check the font on the NGK's, mine had fake NGK plugs in it.

Ha! I didn’t even think to check for that. I’ll take a look and see what I have.

I recently bought a chinese mini skid steer and it looks like it has the same motor as yours. Can you or someone tell me what replacement oil filter I need. It did not come with any documentation or extras.

@lurtbike 11 күн бұрын

Same as a predator 670 motor from harbor freight. You can use the same filter. I bought a Kizut 136-7848 off Amazon.

@jlustig83 2 ай бұрын

Does the harbor freight motor have as much power as the 739cc

@lurtbike 2 ай бұрын

I think it’s rated at 22HP where the 739 is rated at 23.5. I can’t tell the difference when I operate the machine. I think 22 HP is more than enough to drive the hydraulic pump.

I had a similar problem with a new predator 670 (1 cylinder dead out of the box) I did the same quick checks as you did, then brought it back to HF for a refund. I'm still puzzled as to what was wrong, but digging into it more might've jeopardized the refund. I sort've assumed it was a carb/intake issue since there was hot spark and compression. Too bad the China digger builders are moving away from Vanguard 23's.

Yeah so far so good on my predator. I’m up to 14.5 hours now and it’s doing well.

@spin0491 7 күн бұрын

Probably carburetor issue…..had to add a electric fuel pump to mine….I have over 100 hours on it…….

@lurtbike 4 күн бұрын

I have an electric fuel pump on the predator motor now. Low compression wouldn’t be caused by a carb issue. Checked valves too. Head gasket had failed upon later inspection.

@olddirtyburt7522 3 ай бұрын

alot of these companies will send you a new motor with only 5 hours on it. long boat from china.

@lurtbike 3 ай бұрын

Yeah I’ll have to look into that but I’m not sure I want another one if they run like garbage and only last 5.5 hours. This one has a warranty and I can pick up a replacement off the shelf locally.

@shadowstorm1742 3 ай бұрын

The china cheap equipment is pretty garbage toro or Vermeer make a much better dingo that’ll last a lifetime and are actually heavy duty with the arms being twice as thick and can carry more😊

@scottbailey8424 3 ай бұрын

I'm sure everyone that buys a Chinese skid steer is aware of that and know the risks. Some of us don't have 30k for the better US or Japanese units.

@lurtbike 3 ай бұрын

You are mostly correct. And they cost almost 5x as much new. I have less than $7k in this machine and it does what I need it to do. I can’t justify spending over $40k on a piece of equipment to clean up my yard and tinker with. But hey if you’ve got that kind of money sitting around I say go ahead get the Vermeer.

Couldn't afford to buy name brand to play around the house. But we could afford this little guy at the auction and ate having lots of fun with it. kzfaq.info/get/bejne/kK6GltikqbylZ4E.htmlsi=P9cCi-_1XQ2Jf4Bs

3.5k for Chinese or 35k for name brand.... I go to auctions for a living and those "name brand" are junk at 5-700 hours typically .... doesn't sound like quality to me

If buy one always drain old fuel out change fuel filter and oil before really running them. Alot of them when they arrive wont run properly at full throttle, it'll sit there and fluctuate.
