Hi,
I am getting closer to installing the engine and trans. in my 73. Before I assemle everything I want to do as much as I can while everything is apart. I cleaned up the tranny today and am installing a new TO bearing and was wondering about replacing the tranny seals. There is a drive shaft oil seal and a "final drive flange shaft seal". (The small one behind the TO bearing and two larger ones inside where the inner cvjoints bolt on.) Should I change these seals out now that everything is out of the car or should I leave it. None of them are leaking that I can see but that doesn't mean they won't soon. So, to change or not to change. Dat be da question. What do you all think? If I wasn't such a lazy ass I'd just go ahead and do it but I thought I'd get some opinions. So, change em (IMG:style_emoticons/default/agree.gif) or forget it (IMG:style_emoticons/default/pissoff.gif) ? Cheers, Elliot |

I would change them (although I only remember one seal for the
input shaft). When I bought my car, that seal had been leaking, and it was difficult to tell how much due to other oil. But the clutch disc was toasted by tranny fluid, and I drove the car to its new home 800 miles with only 1/2 quart of fluid in it (IMG:style_emoticons/default/sad.gif) Apparently that's how low it has to get before the leak stops (IMG:style_emoticons/default/tongue.gif) |

Yes, there is one small seal on the output shaft and the output flanges have a larger seal. Just take off the flanges to remove and install new seals.

Thanks guys,
They will be replaced. I ordered them today and should hope to get them soon. Lots of little things to do before I get this thing running again. Cheers, Elliot (IMG:style_emoticons/default/beerchug.gif) |

I'd get the entire kit, and replace the everything but the gaskets.
However, if it were me, and I had the tranny sitting right there, I'd open it up and change the 1st and 2nd gear synchro's.... James |

Replace all three.. and consider the speedo drive O-ring, while you're in there. It's only a few more pennies.

I always replace the seal for the shift console on the side shift tranny's. It sees a lot of work and is normally dripping into the plastic "boot".
