    It impresses me, anyway. The fact that all that stuff actually fits inside the gearbox case!

    Now, if only I can remember how it goes back together... :)

    What kind of wear did you find in there? Were you able to get parts without too much difficulty?

    I am impressed! You're my hero! It seems as if you're ready to tackle anything. I thought the rear brake calipers were 'over-engineered' with all those little pieces until I tore into them. Now that I'm finished with one they are as simple as can be.
    By the way, how did you get the case so clean? What did you use to clean it? Painted or natural? It looks awesome!

    Great shot! What's the motivation for the teardown? Or did you get carried away...

    I don't see the gear that changes from longitudinal direction to transverse direction. Did you leave it in the case?

    Mitch it is in the case with main shaft and a bunch more gears. You know Ric...you probably do...once you pull those shaft end bearings you screw the relation of the main shaft to the pinion gear so you have to shim the pinion or you will blow something.

    Inspection mostly, I figured since I had it out of the car, I'd replace the prawl springs, as they're reported to weak fairly quickly.

    Ric,

    You have come so far...I would take the rest of it out. One box I fixed did not have this part in spec and was missing teeth here. I suspect that these boxes loose the preload here and then the pinion migrates into the main shaft. I would at least prusian blue the pinion to mainshaft to make sure the obvious. You can't check the preload with the mainshaft in place.
