Transmission Overhaul
There's not much to show; I split the transmission and took out the gears. Getting the end nuts off requires some leverage. To aid in removal, I drilled two holes through an long piece of steel (the kind that has two flat pieces welded length-wise at a 90 degree angle) and threaded this back through the transmission case. Stepping on that steel and using a long breaker bar for leverage made quick work of removing those nuts. Removing two of the four large bolts holding the sides together was a lot more involved!
Now it's time to clean up the housing, repair the 2nd gear roll pin, and put the guts back in. Overall, the insides were great, though the oil was old and nasty. I'll probably fill it up with regular oil and run it for a little while before putting in the Red Line 75w90NS (my gear oil of choice for the DeLorean).
Removing the fifth gear cluster. I also have gotten hooked on these medical-grade nitrile gloves that a friend brought over to the garage... these are MUCH stronger than the other nitrile selections from the auto parts stores (and my favorite of those has recently gone away). It'll be a sad day when the current stock of these gloves is depleted (small things make me happy, clearly).
Case split, transmission internals.
... And one with the gears removed.
This little guy is the biggest problem with the DeLorean transmission: it's the 2nd gear roll pin, which tends to sheer off if you use the car with a bad (plastic) clutch line. It takes all of two minutes to carefully replace... once you pull out the transmission, open it up, and take everything out, of course...
Here's the new piece inserted and ready to serve. This one has an inner pin to further strengthen it.
New axle seals, installed with anaerobic sealant.
New input shaft seal - always exciting.
And these 27-year-old o-rings were due for replacement too.
