Anyone have any additional adivce or tricks for installing the shaft coupler onto a non-tapered shaft? I am on my third attempt (first one accidentally got put on backwards - I'm an idiot! ) after I failed to get it pushed all the way on before it cooled. I was short by approx. 1/2" of where it needed to be. I heated it at 500 deg in the oven for an hour, and it is now a pretty blue! Off to remove it and try again.............I guess. Not sure what could be wrong. Will try some emery cloth on the shaft just in case there are some high points for whatever reason; shouldn't be after the machine shop cleaned it up by polishing.
I'm in dire straights here and am about to lose my mind if I can't get this to work. What other options are there?????? |

Robb I think you are on the right track and what you could do is find some dry ice and freeze the end of the shaft before you place the coupler on. If you aren't in a position to do so then it might need some friendly persuasion. Don't hit the coupler directly with a heavy hammer but a block of wood. Can't imagine it would take that much. ------------- "Morfoot; He can ski. He can wakeboard.He can cook chicken.He can create his own self-named beverage, & can also apparently fly.

Tim:
Got it!!! Thanks for the encouragement. I desperately needed it. I just worked on the shaft and bore with some emery cloth for a bit, and that did it. I'm now having trouble with the alignment of the motor to the coupler. I've done this before, but I had to shim my strut about 1/4" to get the shaft centered in the log. Anyway, as you can imagine, the coupler end shifted the same amount. The front mounts don't have many threads left to go vertical and still tighten the nut, and, I can't figure out how to move the trans up and down; I've only had to move it side to side. I loosened the big jam nut and then tried wrenching on the top of the bolt, but it won't budge. Used plenty of PB blaster. There's a nut underneath the mount - should that be loosened?? If so, I'm not really sure how to get to it with a wrench. |

Robb - You make have to put some shims under your front mounts.
You also may have to remove the rear mounts from the tranny & put them in a vise. Then you can get the torque you need to break the adjusters loose. Good luck, this is important work you are doing! ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

Okay, making shims had crossed my mind. So the way I was going about trying to loosen the rear mounts was correct, but they are just terribly corroded? I will get to work getting them removed tomorrow first thing so I can attempt to break them free.
I would assume that blocking and jacking the engine is in order here?? Thanks for your help on this! |

yes, and put a block of wood between the shaft end and rudder, and TAP, you only get a couple of seconds so make it count ------------- "the things you own will start to own you" |

Robb - You can pull the trans mounts by using a jack (I used my truck's sissor jack) under one of the exhaust manifolds. Of course, also block it up for safety. Another tip - loosen the front mount's pinch bolts so they can pivot. Otherwise you would be over straining the rubber. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

| Made steel shims and installed on the front mounts. Also removed the trans mounts to try and break them free. I put them in the vise, and I cannot get them to budge at all. Would putting heat on them with a torch help? What else can I try? |

Heat might help but don't cook the rubber. Maybe someone has some used ones you can get. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |
