I have replaced leaking seals at the front of the differential and and the rear of the transmission (4 speed no overdrive). This transmission has spent 10 months on its nose (bell housing) with gear oil inside and hasn't left a single drop. I'm leaning towards not touching that seal since it hasn't leaked. Sound okay?
Regarding the clutch release shaft - what a pain in the rear that was. The pin locking the fork to the shaft broke at the end and I could not extract the bit that was left inside. Eventually I gave up and cut the shaft and removed it. Still could not get that little bit of the pin out, so I added a new fork to the order.
ps, I made a real simple tool that I used to remove the other seals - see photos. It is 1" by 1/8" flat bar bent over and trimmed so it hooks the inner side of the seal. The other end is also bent 90 degrees but long enough to strike with a hammer. Overall length is 18" approximately. Just a few taps as I moved it around the circumference did the job. The "L" that hooks the back of the seal is about 3/8 - 7/32 and rounded a little to match the seal curvature. This explanation took longer than it took to make the tool.
