Featured Replies

  • Author

yeah thats why i was asking i just didnt know if they have the same sizes

out of all my cranks sitting standing on flywheels in my shed (4K-e, 5K, 3K, and 4k) All use the same bearing size just the stroke changes so need a 4K crank in a 5K etc.

:dance: :yes: ;) From what I have seen when I pulled one of my 5ks apart, the 4k and 5k share the same crank as it is only the bore that is larger on the 5k and the crank had raised lettering saying 4k.

that'd be right. a a 4K is a Stroked 3K, a 5k is a bored 4K and a 7k from what ive heard is a stroked 5k???

I don't have a friend named Goole? :dance:

 

 

don't think you have one called Goolge either lol

yes fits all 3 motors, but the is changes to the mains in the 4k & 5k (groove in the bearing only going 1/2 way round on some) but sizes the same
