The one I like is kleen, tell me if I'm wroung with the old diesel engines don't like the new epa fuel, it treats 100 gals for 16 oz . I figure about 16 oz is what I use for 25 gallons. It also helps lube th...

Jay No that would be mild steel so it can take the stress an flexing . Hight carbon steel would be on the tracks , pins, rollers, wear plates on the bucket and teeth. There is alot of cast iron on the machine. You can do a spark test with grinder ,harden steel will have a very fine spark. cast iron ...

Jay . My 350 will unload any pressure with the spring on the track adjuster, it shouldn't through a track if evey thing is working right an the adjustment is ok.

Jay. That looks to be easy repair for a decent welder.

Alot of times people will put on a "C" series decal. Check under the seat to see what type of steering it has in it. If the steering clutch handles are connected to a valve on top of the transmission it is a "C", if has power assist between the steering clutch housings and the clutch levers it woul...

Reverser line running to the front of the radiator rub through leaking bad. Power washed where I could see what is going on just a big pain in the neck. I cut the metal tube with drimmal an slipped a 1/2 rubber power steering hose over the tube clamping it then to the reverser tube. the way I seen i...

willyr good call on the radiator . If I can see collant looking in the radiator it's good . It will alway take about 16 oz an it always spits it out through the over fill. I really need to dump an flush the system, no telling how long the collant has been in . I look at my crawer an see how much wor...

There is no cheep crawer, Look on E Bay. I'm always looking around for old Jd crawers, acutally some brought in a 450 70 model 1/2 mile from my retirement home looks to be repaireable . It has a winch off to the side not shure why . good luck

Rodger . It sound like both seals are blown out on the adjusters. I rebuilt both adjuster. One was froze up bad, but they both hold an had only to adjust them after rebuild . The job is feirley simple after the track is removed.

Model 3J4121 case it has 8 inch bucket , It will be good for planting trees ,an setting fence polls. The crawer came with 93 A hoe 24 inch bucke That is burte and to heave for counter weight.

I had 1 missing snap ring also. I used a 3 inch piston ring that was the same thickness .

I could shure use that around my place.
