Ah the gearbox input shaft!
Last Saturday I planned a "quick" (ten minutes I thought) replacement of the seal and little brass bearing behind it before finally putting my gearbox onto my new engine and putting it into the car. How I was looking forward to the latter.
Result: after much swearing and consulting my knowledgeable friend, the diff. was taken apart to free the seal, bearing and shaft. At least I know how it is put together!
