Yanmar repair help

Hookie · Feb 16, 2010

Just bought a used (934) hour tractor. Model ymg 1800 d. My problem is only one rear wheel will turn other is frozen.

Tractor sat for 4 years and got it started and try to move it and wheel stuck. All three other wheeels work 4 wheel drive.

Where can I find Parts & Service Manuals for this tractor. Was told it is a 1979 year gray tractor fro Japan. Price was right (1000) and the old guy has 6 more like this one at same price.

I don't see that model on Hoyetractor but here's a diagram that might be similar. (YM2000).

It is real common for the brake shoes to stick to the brake drum. Taking off the brake housing cover, (#4) on this model is simple (when it's not stuck) maybe an hour including slipping the fender back to make some room. On this model the brake shoes and the anchor that the shoes pivot on, come off with the cover. Add maybe a half day if everything is stuck so bad that you can't get anything off initially.

Don't get oil on the brake linings. The linings last near forever and cost like they were made of gold. That brake enclosure is sealed because for rice paddy work the tractor gets near submerged. For US use, I think reusing the paper cover gasket is sufficient because we don't go into 2ft of water.

I hope your model is similar to this.

Good luck.
