200 Allis inj. pump problem??

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   My 200 is experiencing some issues. It starts fine. But runs like crap. Sounds kinda spitty when its running like a miss. Last fall it would now and again drop rpms and lose power when using it,  Now.. the crankcase is overfull, and the oil is thin from diesel.   It does blow some light blue smoke, most likely from the diesel in the oil??  It will run out of power just going up a small hill on the road and die.  It will not start right back up until I use the hand primer on it. The last time I had a fuel starvation issue with it, it would act similar to the power and rpm loss, but would not even tach up past 1800, now it will however tach up to 2500 rpms. yup all fingers point at a flow restriction, but where is the diesel in the oil comming from? Is this the gov ring problem in the pump showing itself? The tractor has Almost 7000 hrs and the pump has factory twist locks on it yet. any thoughts? Thanks.

	The shaft seals are bad had the same thing happen on my 180 and that is why the crankcase is overfull most likely. As for power loss and stalling out, it may be due to the flex ring deterioration as most commonly it is. It is clogging the return with little black pieces of rubber from the flex ring. Also had this happen on my 180. Had the pump rebuilt and runs beautifully now. I would say with 7000 hours it is time for it to be rebuilt.

	flex ring pieces plug return, housing pressure goes up high enough to either just kill the tractor(housing pressure and transfer pressure equalize)and or lose power, and it ends up blowing the driveshaft seal. The smoke is probably due to the dilution, as well as just being so over full. Let me know if I can help with pump work. Ed.

	May have some bad injectors causing it to run poor. A tip blown off a injector will also put fuel in oil. Sounds like time for pump and injectors both rebuilt. MACK
