Acording to the photo, the splines have not engaged or the TO brg is not sliding onto the Collier. Put the trans in gear & turn the yoke a little to let the splines mesh with the clutch disc. Make sure the angle of the trans. is the same as the bell housing. Move the clutch fork a little if the TO brg. is not on the coller. You shouldn't have to push much if everything is lined up.
