You need to find why the resistor blew in the first place.
Simply replacing will likely result in the new one fried too.
These are the classic old TRW/IRC BWH resistors, relatively cheap wirewounds with cruddy wirewound elements on fiberglass cores that normally you'd see in a tub full of cement, but here with phenolic overmold. The overmold aways cracks and pops off like that when they're stressed. In my last job, we used them all the time for low value current sense resistors. The giveway for the type is the broad first stripe and the dullish phenolic overmold, not shiny like most carbon comps. There are lots of better replacements. BTW, theyre not fusible resistors.
