Smokey 5103

[usmc5595]

You can loosen the injection pump, turn it slightly clockwise, and retighten. Advances the timing and white smoke should clear right up. Not a rare problem with 5003 series tractors. Happened on about 20-30% of the 5003's we sold.

Mark the pump and housing before loosening any bolts and you'll have a "reset" in case you turn it too far.

will this same thing work on the 5103's????

Could you post some pics on a "how to" or is there one some where on this site? I searched but came up with nothing.

i am also interested. my 5203 isn't blowing out any white smoke that i recall when it hasn't been ran in awhile. i get more of a light black smoke when it first starts up but only for 1 second. maybe it's due to not getting that cold in SC? although we did get snow this year:laughing:

Any photos of where to start??

My 5203 is a 2004 model - one of the earlier ones without a turbo. It has a Stanodyne fuel pump with a "cold start advance" to automatically advance timing when the engine is cold.

This spring, I found the wiring from the cold start advance switch / thermostat pulled loose -- likely from a branch or limb. I reattached it without any trouble and tucked it a bit deeper behind the fuel pump.

I don't know if the newer 5X03's have a cold start advance, but I thought I'd mention it.

I discovered the disconnected wiring when doing a visual check this spring. I repaired the wiring before starting the tractor, so I didn't get to see how it would have behaved with the wiring disconnected.
