MZ TS 250 Crank Seals

[matthewjames]

Hey Folks,

I'm in the process of replacing the crank seals on my '74 TS 250, and I've noticed that the book says that the seals should measure 30 x 62 x 10. The old ones I took out measure that size as well, but when I look on the web, everybody is selling seals that measure 30 x 62 x 7. Does it matter which size? Is the wider seal better? Why are we not using the original size called for in the book?

Thanks,

Mr. Matt
