Front Crank seal dimensions

I am wanting to change the leaking front pulley seal on 2.0 type 4 with a double lip viton seal. Can anyone confirm if the inner dimension is 41 or 42mm. Most retailers don’t list the size. One that does says 41mn another says 42mm. All a bit vague.

 

I've a new stock one in a box at home.. cam measure up later if any use?

Yup. It's a 42 - you can just see the numbers stamped on the seal .

 

Thanks for the info guys. Pretty definitive
Have ordered the dual lip viton in that size.

 

Let us know how that looks.. might consider one!

 

Works well on rear crank or should i say not leaking yet
Local bearing suppliers only had 8mm wide which probably would have been ok.
But went for correct one on flebay

 

What dims are the rears then?

75x95x10. However the depth in some cases varies. Search thread “Oil seal recommedations”
Some good info
