The $600 project Rancher 400AT

Hi All. It may not look like it now, but this is a 2004 TRX400GA4. This was a farm vehicle used by an old man and his family around the farm and ponds.

Of course, the first thing I did was find this forum and download the owners and service manual. Thank you for posting those!

The bodywork is all there but one of the plastic flares is busted up. It’s all in pretty rough shape but it’s all there. I can order another flare. The racks are there but in need of paint. All of the emblems are long gone. The tires are there but in dire need of replacement. The wheels are bent up so those will likely be replaced. The frame has a good bit of surface rust which I will likely touch up before putting the body back on.

As you can see, this is where I’m at at the moment. I took the body off and washed the first layer of mud off. All fluids have been drained and the oil filter removed. I have taken apart all of the electrical connectors and cleaned with Caig’s DeOxit. Put them back together with a dab of silicone grease. All lights work as does the display.

The rear brake was holding when the front lever was used. I took the cable off and lubed it and adjusted the brake and took care of that problem. Other than that the brakes are good. The steering had an obnoxious squeal so I took the top bushing out, cleaned the bushing and shaft, coated it with lithium grease, and replaced it. Torqued to 24.5 Ft.lbs. and smooth and quiet now. All of the ball joints and steering joints seem tight and there’s no play or lost motion.

It runs like a top. Starts as soon as you press the button and idles very quiet and smooth. The transmission doesn’t seem to work properly but it was about 2.5 quarts low in oil when I bought it and what was in there looked pretty thin and nasty. It looks like there is an oil leak at the rear of the motor where the pull cord is. The air filter was, believe it or not, very clean. I am getting a 12 blink error which is the ECM motor driver circuit. Hopefully oil and the clean connectors will fix that. About to go out and adjust the valves and clean the pan under the tank.

In the next few weeks I’ll get the rubber hoses replaced and take the brakes apart. Check further in to that oil leak. Fill with fluids and hope that fixes the ecm motor error. Get some tires and wheels and go from there. I’ll try to update this as I go along.

Thanks for the help!! Now for the obligatory pics:-)
