JD w/excessive smoke

[jpolston]

Need advise,



It's cold here now and I have not done any troubleshooting yet, but I'm looking for suggestions. I used My JD 5400 tractor recently and it smoked excessively ( black smoke ). I'm pretty sure the breather is clean, I have changed it recently and it does not have many hours on it. I believe it could be a bad injector, but not likely. ( the tractor only has 500 hours on it) The turbo could be frozen up, I'm thinking with so little use, it might have a bad bearing from sitting months without use. Finally, the fuel is old, I have a farm tank that I fuel from and the fuel is quiet old. ( 8 years ???). As you can see, I don't use this equipment very often. I've only put 200 hours on it in the last 5 years. Thanks for any insight.

Smoke

Fuel without enough air, sounds like the turbo is not turning or restriction in the air intake. bg

I had exactly the same problem. Short oil return hose that connects the steel line from the bottom of the turbo to the block was kinked causing turbo oil seals to leak into the intake. The hose is prebent about 4" long, JD parts guy said it happens all the time, too much heat. Of course JD wanted too much for the prebent hose so I just bought some bulk hose for 50¢. At least 4000 hrs on the 50¢ part now.

If it sits that much, do the birds or mice have fun building nests in the intake? Used to have that problem on my boss' irrigation pump engine till I put screens in place to keep the mice out.

If the previous suggestions don't get you going you might want to call Southeast Farm Equiment in Lumberton NC at (800)451-1375 and ask for Bobby Cox. Bobby turns wrenches for JD during the day and for himself on nights and weekends. His personal rates aren't bad.



What night is the auction ? I'll be looking another horse soon.

Don't know if JD uses this but my dads MF 253 had something similar happen to it. The MF has a fuel preheater nozzle that injects fuel past/thru a heater solenoid in the intake. It hung open and dumped fuel into the intake, smoking like crazy. Simply unplugged the solenoid to stop the smoke. No start up problems either. .

Boss' grandpa has a Deere 850 with the same style preheater. Don't know if it works though, never need it.
