Afternoon guys! Just wondered if anyone can shed some light on how to remove the 2 smaller sprockets on the balance chain! I did try plugging a dowel to lock the sprocket off but it just keeps slipping off! And the dowel hole isn't very deep and spins out! Just wondered if there was a trick you use to remove them! Engine is still in the car so space as you know is quiet tight! And no access to air tools! Any help on this would be great! Thanks in advance Rob
