Assuming you have a Weller gun, higher watts the better...
After checking for wafer damage, put a secure clamp on the shaft that won't damage the shaft.
Prepare the Weller gun by removing the tip, using another set of tip nuts make two 2" wire extensions from the gun using some #12 or #10 wire. For into a "V" to wedge the shaft and/or the threaded collar.
Apply a tiny drop of the lightest oil around or mineral oil to the shaft/collar. Apply the Weller tool so current flows trough the shaft or the collar. This will effectively heat the assembly in about 5 minutes the hard grease will liquefy. Apply gentile torque, once the shaft moves even a bit apply more oil and heat, repeat until full movement is made. As the shaft cools continue gentile movement while applying fresh light oil. Shaft should be completely free when cool.
YMMV
