If you want to fill any cracks one way is to force a snug fitting
rubber ball down the chimney to where the liner starts and then throw
some loose refractory grout down on top of it. Then pull the ball up
with the rope slowly while checking that the grout is around the edges
and being forced into the cracks. Add more grout if needed. When the
ball gets to the top your chimney should be repaired but you should
install a new cap. I have done this a few times with good results. I
have used a flat disk with a wooden rod through the ball and a hook or
eye bolt on the top to tye the rope to.
