Primary Key in Transactional Replication

How I can publish tables wihout primary key in transactiona Replication?
Dave,
you can't If at all possible, just add the PK.
As a workaround, if schema changes are not allowed, I suppose you could
create an indexed view and transactionally replicate this, but this is not a
nice solution.
Equally not-nice is to use a trigger to synchronize another table (which
itself has a PK) and replicate that.
Finally, you could use snapshot or merge replication (EXCHANGETYPE to force
downloads only), but these may not be appropriate due to their nature of
replication.
