You can drip very thin super glue under the clicker gear. Spin the gear and drip at the same time (have acetone on hand for the times you glue yourself to the spool). With time the repair won't hold up.* If you
really must fish a 1774 long term, drill and pin the clicker gear to the spool (don't even think about trying this with a Dremel tool).
But face it, life is too short to put lipstick on a pig.
Read the
Click pawl reels thread - all 24 pages of it. There are many, many, better reels than a Pflueger 1774 (or the more recent version, the Pflueger 576 Trump). Start with a decent reel, clean it up, and fish it. For example, the Airex Meisselbach** Ablette reels will work much better than the 1774. If you don't mind red, look for a South Bend Finalist 1122. The Hardy made System reels can often be found for a nice price. The beat up ones usually fish just fine after a
full bulldog cleaning, and the drag has mellowed with time. The newer Pflueger Supreme 1834 or a BassPro White River UL are modern reels that often sell relatively cheap. Watch for poorly presented classics on eBay. There are
plenty of better choices.

* For the record, I have 4 copies of the aluminum frame Pflueger Trumps. I set them up with 4 weight through 7 weight lines. The reels have
cork arbors and just enough backing that all the reels come to the same weight. I use these for test casting so the reel weight doesn't effect the casting feel. I don't need a drag for grass trout. The Trumps are excruciatingly cheap reels, but that's fine for this purpose. Take them fishing? Not a chance.
** No relation to your other Meisselbach reels - but
bulldog1935 tells that story much better than I do.
