I've got a friend who has been inside the tranny alot and is going to help me pull it apart and reseal it. Presently it leaks but can't quite tell from where, looks like at the intermediate plate. He's recommending replacing the two bearings in the intermediate plate, since likely never been done. Why? Because they are most likely pitted and will require replacement, his words. He used to race locally and tells me he would change out his gears almost weekly depending on which track he was racing that week (so I think he knows what he's talking about). I know he is conservative (engineer in aerospace industry), but I'm curious how often these bearing actually fail?
Also, I see they're not cheap; best price I could fine was $168 ea. Sound like the right price? Kev |

If they aint broke, dont change them. The lower one seldom goes bad and at times is hard to find. The upper one goes bad more often because it sits out of the gear oil and is the first to dry up when the oil is allowed to go too low for too long. A simple test to see if the bearings are ok is to see how far you can spread the pinion and drive shaft apart. It should not be much. If you dont have a press then removing the drive shaft to inspect the upper bearing can be dodgy and may actually cause you to wreck stuff. But, if your friend is willing to remove the shafts so you can inspect the bearings up close then have at it (IMG:style_emoticons/default/biggrin.gif)

QUOTE(Dr Evil @ Aug 13 2007, 11:10 PM)  If they aint broke, dont change them. Yeah...my thought too. The picture he's painting is its cheap insurance, if the bearing comes apart, it will tear up the entire gear stack, (IMG:style_emoticons/default/chair.gif) No where the bearing can be had new least expensively? Thanks Doc. (IMG:style_emoticons/default/thumb3d.gif) |

GPR is where I got the prices I qouted. Surprised that my local dealership was only $15 more. I got that price before the GPR qoute so I was hoping I could find it for much less (1/2) the dealership rate.

One more question, can anybody tell me if the rebuild gasket sets contains ALL the seals & gaskets? Including shift shaft seal and drive shaft seal?
Thx, Kev |

Yup, sure do. The only seal no contained is the seal inside the speedo drive (not a big deal). The O-ring out side the speedo drive is in the set.
