In the middle of a clutch job- picking up the resurfaced flywheel tonight.
Do I bother replacing the main seal if it looks ok? I've got a new one standing by, but for some reason have hesitated. Maybe it was because I've read that when taking out the seal the shims will fall out and that have to be put back exactly where they were before. What shims? I can't find any pictures of these shims or other info other than talk about them on engine build threads.
If the new one will last longer than the one that's in there, it probably makes sense to replace it. I don't want to have to do this job again any time soon.
