Speedo gear - oil seal dimensions
« on: April 03, 2018, 01:00:36 AM »
Wanted to take apart my speedo and clean it. But realised Honda does not have oil seal as spare part.

Does anybody have experience? I measured 47x34x apprx 6mm w/o taking old seal out of gearbox.

On the seal I can read: AE1967E

Or where to buy proven one?

This thread helped me to find one first time.  I found one locally 34x48x8. I could grind it down to almost 7mm and it work fine on my K6

So dimension 34x48x7 with double lip is the right one?
