CHEERS FOR THAT INFO M8
I AM HOPING 2 ONLY REPLACE THE 1 PISTON THERE IS NO RIDGE ON THE BLOCK ONLY BITS OF ALUMINIUM SPLATTER
ONTHE SIDE SHOULD BE ABLE TO HONE IT AWAY I HOPE

I HAVE ALREADY TAKEN THE HEAD OFF ,I THOUGHT IT MIGHT BE EASIER TO DROP THE SUMP IN ORDER KNOCK THE PISTON FROM THE BOTTOM UP BUT THE SHAFT LOOK LIKE ITS RUNNING THROUGH THE TRANSFER BOX AND THE SUMP

WORSE CASE SCENARIO CAN THE CYLINDER BE RESLEEVED
