350B missing after running OK

[tmlkenney]

Hi,
Hoping someone can help. My 350B runs like a champ for the first 30 minutes or so after startup and then suddenly starts to miss/cough/sputter. After cooldown, same cycle, etc. I've checked prior threads but can't find one on topic. Anyone have any thoughts? Your help would be much appreciated. Best regards, Tim

Hi Tim-

There have been some threads about this- I will try and look for them but JDEMaris or one of these other guys probably remember the threads and can get to it before me.

I think I've found it now. Screens, fuel, injectors and a little hope. Thanks for the help. Tim

A long story short - if it's a diesel. The injection pump - if a D series (Deere DB or JDB) - has a piece of plastic inside of it that goes bad every 10-15 years, regardless of use. When it falls apart, the crawler will sputter out and die after being run for awhile. Then, after shut-down, will start fine - and run fine until it craps out again.

It can be fixed in a few hours and with $25-$50 in parts. It can also be upgraded for an additional $45. If you don't know anybody that knows how to work on it - then a cheap repair job will become a very expensive one.
