In a course of a week I have purchased two 200s. This orange bug hits hard when you get it  one of them is leaking fuel at the throttle shaft at the pump. It feels like the bushings have play in them and that's what took out the seals? Does anyone know where I can get new bushings and seals or should I just get a reman pump?

thanks for the plug. If it's just leaking there and runs good, you may buy a little time by trying to replace the 2 orings yourself. The problem is, I don't think the throttle shaft will come out of the pump with the pump on the engine. That should have steel bushings, so orings will likely seal it up. The other problem is, all the other orings are going to be hard and flat too, and will start leaking soon after. Like I said, you can buy some time, but it will not be permanent. ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".

One has to have a short allen wrench and remover the over travel spring assy which is the same on the inside as the outside - the out side is visible as an instruction visual. The top of the pump will have to be removed after removing the vertical drip line. There is a "J" clip that holds the outside fuel shaft off shaft to the inside throttle shaft - they join in the middle like a splined pto shaft tractor half and implement half. (Do not let the J clip fly off into space when it flips off. ) Remove the shafts and replace the o rings and reverse the process. The super clean sulfur free fuel has little lubrication. We went 35 years with little or no issues - we now do one or two CAV pumps per month as to replacing seals curing leakages. ------------- When told "it's not the money,it's the principle", remember, it's always the money.. |

| Tbran is correct,it can be done on the tractor. It's a little tricky. |

| Thanks for the replies I have the pump off of the engine. Do I need some special o rings to try to reseal it? |

Curious if you lined up the timing marks before you took the pump off of the engine? ------------- 80 7010, 80 7020. 67 190XTD Series I w/500 Loader, AC 2000 Plow, Member Indiana A-C Partners, Member TAC |

| I'm with Ed on this one, If the throttle shaft seals are bad,,, how much longer is the flex ring/governor retainer ring gonna stay together... |

Yes I lined the marks up before removing the pump and was wondering if Tbran or Ed was going to GOTO in Tennessee next week and would want build a pump in the parking lot
