Or support the gear stack vertically, between the jaws of a vise on a sturdy workbench.
Take a block of wood to protect the end of the shaft and beat away with a BFH You should be able to drive the shaft out of the gear stack. I then go over the input/output shaft with some crocus/emory cloth and reduce the amount of interfernce between the gears sliders spacers etc.. so you dont need a press or BF next time around... The guy whose name escapes me now.. he rebuilds the trannys for PMNA showed me this trick |

Even that mod to make the gears slide more easily on and off needs a lil more splainin
you really should chuck the inpu/output shaft in a lathe to do this |

Did you even read my article?
BFH. Use a brass one and be gentle, but forceful. |

Go buy a $20 BRASS BFH (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) and beat the shafts out of the bearings. Once out the gears slide off. Remember, brass is soft, steel is way harder! |

I used one of those gear puller/bracket things like a press. Worked like a charm by pushing the shaft out of the intermediate plate.
I can take a picture if you want |

No idea what those output flanges are worth. If they are like the 912 trannies I took apart, they're different and wouldn't fit a 914 trans.

Use the HB flipped for 5th. It gives more overdrive..... What you end up with is a close ratio 4 speed with a long legged 5th for highway use. |

too tall i believe. more suited for a v8. not enough torque from a four banger....
and the gap from an S 4th to a flipped HB 5th would be huge! imagine that downshift... waaaoooo weeeeeeeeeeee |

Actually, that's the exact gear set I have for my /6 conversion.... Recommended by 2 long time Porsche people, each not knowing of the other's recommendation. As soon as my car is on the road I will let you know how it works! (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif) |
