just bought H-3 looks likes rails are worn at the front.can they be fixed by building up with weld .also how tough and reliable are these dozers.

I owned my H3 for almost 7 years now. Replaced one roller and a head gasket. Has alot of power for a small machine, but I would never sell it or trade it off. Has always started right up even after sitting all winter. I don't know if welding on a build up will help, but there is aplace near me in Honesdale , PA that has dozens of these machines sitting around for parts

turns out what is worn are the fronts of the stone guards. the shuttle clutch needs attn. should i change the oil and replace with 20-20w or auto matic trany fluid. also steering leavers need adj. any tips on any of this.

I don"t know the oil spec for the shuttle, I have 30sae ND in mine. Right above each rear sprocket you should see an adjustment bolt with a jam nut for the steering clutches. You should have about 1 to 2 inches of free play on the steering levers. I know with mine the steering clutches sieze up when I leave it sitting for too long, in that case you would just walk her up on a big tree and pull back on both steering levers until while braking at the same time the tracks stop moving.
