I just got a Top Racing crank for my E50, and I wanna know if it's supposed to require the same size seal on each arm... only because the hole of the 22 40 7 seal is too big for the clutch side arm. Both arms require the 17 40 7 seal as it seems.
My other DMP crank is different. On the clutch side arm it takes the 22 40 7 seal, cause it has that extra little shelf that it fits up onto, as does the stock E50 crank if I remember well; the Top Racing crank doesn't have that extra shelf. So I just wandered if you're aware of this, and if I'm fine with using the smaller 17 40 7 seal on both sides.
My apologies if this would fit the repair forum instead. Thanks.
