Not if the ratchetty bit is stuck "open" and not engaging at all. The grease hardens over time and accumulates contamination which gums it all up. Liberal WD40 works but you could speed things up pouring a hot (not boiling) kettle of water in the internals. Once something gives, repeat the above until it's smooth.
I was going to suggest a bit of kettle action, too. Is a hairdryer a viable alternative? I was wondering this recently, in case there’s something you don’t want to get wet for whatever reason.
