Hello All, My father-in-law is trying to install a rebuilt fuel injection pump but says it is spring loaded and having trouble getting it to go in. Is this normal? He says he replaced one before but doesn't remember having this much trouble. He says he will have to leverage it in with some kind of jack to hold it steady. Appreciate any input/suggestions. Thanks Steven

| Any rebuilt pump should have throttle tied wide open until installed. It should slide in place with no "spring" effect. Sounds like people don't know what they are doing....Leverage and jack should not be included in this conversation. |

Sounds like it wasn’t timed when it was pulled so it’s not lining up in the pump. Pump rebuilder should have the pump timed when it came back. If the timing window is removed are the timing marks lined up? As Steve said, force should never be used. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

Gentlemen, Thank you kindly for your prompt responses. I will be sure to inform my father-in-law of your responses. Hopefully, he will be able to make adjustment so the pump will install without any undue "force". Thanks so much!!! Steven

Do you have the tool to protect the seals as you put it back in? |

In response about the tool to protect the seals. I don't think he (father-in-law) is using anything to re-install it. If you could point me to the tool you are referring to, maybe I can persuade him to get one. Or I might get it for him depending on the cost. A link would be most helpful. Thank you!! Steven

Think I know what he is saying…the tang is not entering the groove…make sure to install dot on tang to dot on inside groove. ------------- Blue Skies and Tail Winds Dana |

I don't know much, but I do know that no force should be required to install it!!! Darrel |

| Look at the pump driveshafts end. It is a flat tang drive. On one end of the tang there is a "DOT". Look inside the pump's driveshaft hole. There is a socket for the driveshaft tang to engage. It too has a DOT on one side. With a clean screwdriver, rotate the pumps socket so the DOT aligns with the shafts DOT and push it together. |

I hesitate to post this picture due to size and that it’s my D17 not a 301 engine like he is working on but same principle. The shaft will have 2 umbrella seals on it facing opposite ways in the groove of the shaft that enters the pump. That is where the tool comes in handy, basically acts as a wide set of tweezers that surrounds the seal and holds it flat so the pump can be slid over the shaft so the pump doesn’t flip the seal over. As you slide the pump over the first seal you slide the tool over the next seal to prevent it from tearing. Make sure all these areas are clean and apply diesel fuel on the seals before you start. It acts as a lubricant. The tang on the end of the shaft has to line up inside the pump. Wish I had a picture of the inside of the pump but I don’t. Hope this helps. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

I guess for seasoned diesel mechanics you don’t need it. I’m a farmer that has pulled a total of 4 pumps and installed them. It has worked for me every time. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |
