how do you get the tapered pins out of the universal joints on the fuel selector assembly rods? pin punch or is there a tool to do this with? |

I think I just used a small brass hammer. |

Back it up solid. Make sure your hitting or pushing the small dia side. Some quick heat from a propane torch or heat gun can help if in an alum casting or machined part. Modifying a C clamp or other type of clamp has worked for me on occasion if you can't get straight on to hit with a hammer. Sometimes your back up mass needs to be machined to fit the contour of the part. I've distorted tubes before by backing up with something flat on a round tube. |

I think I just closed up my vise until it was just larger than the big end of the pin and tapped it through, using the top of the vise jaws as a cradle. |

Thanks BDK and Rich I am trying to get the fuel selector rod disconnected @ where it exits the fuselage and enters the wing main plane in order to demate the fuselage. I'm pretty sure this thing hasn't been taken apart since Navy service. I soaked the pins with mouse milk, a little heat gun action and hopefully they will start coming out. Rich, you are entirely right this has to be backed up well, the last thing I want is to bend one of these little connecting rods or destroy a universal joint. This is not a spitfire, no malletizing allowed!! Thanks guys!!! -Robert Starnes N11SH SNJ-5 |

I thought the taper pin was where the fork mounts to the valve? Aren't there cotter pins holding the u-joints together? Look here where I took mine apart: http://at6chino.warbirds-online.org/?p=33 |

I am trying to take the rod out of the end of 1 of the universal joints, and leave the "gearbox" in the wing. The universal joints are taper pinned. I am trying to take it apart right at the bottom of the fuselage where the rod then connects down to the gearbox. I may be wrong because I am not looking at it but I think our assemblies are different. |

The gearbox is midway between the wing and the hydraulic shelf. The fuel valve itself is in the wing. I posted a bunch of my build on WIX before the blog. You mightwant to search. I gave up on the blog because deleting all the spam was too tedious. The spammers won. What a shame. |
