Tractor Maintenance
« Thread Started on Nov 3, 2009, 9:09pm »
I fixed a couple of problems today that I have put off over the past year.

The front end loader on my JINMA 354 leaked hydraulic fluid out of the two hoses that feed the cylinders that tilt the bucket. I took the fitting off and took it into a hydraulic shop yesterday. They showed me the o-rings that were leaking. I haven't had any experience with hydraulics. The o-rings were cheap. It took me a couple of trys but I finally fixed it today.

My other issue was a very fast idle. I looked the throttle linkage over closely today and lubricated it. The rod that hooked up to the injector pump had all the adjustment taken out of it in one direction. I hated doing it but I: removed it; cut it into two pieces; and welded a piece in the middle of it thereby making it 1.25 inches longer. I put it back on and now it idles beautiful!

Good Show CopperHead,

The Chinese Tractor's are pretty simple Built,, and that's one of their Great Advantage's.

It's a really good feeling to be able to fix and maintain your Tractor, and congratulation's on doing a well done job,
Joe :)
