If you are disassembling the rollers for the fairlead you will need to use a torch and a shop press.
The long rollers have bushings on either end that are about 50mm long. You will not need to heat the entire roller, just each end. I used a 19mm impact socket to support the fairlead frame while I got the exposed end of the bolt pressed down into the roller. After that, a length of thick walled steel pipe for support. Use a steel bar to press once the bolt is inside the roller. It helps to add some lubricant into the roller once you get some space in there, its acts as a reservoir throughout the job.
After disassembly I noticed the the vertical bolts for the rollers came with at least 2 different thread pitches. Interesting, there would have to be 2 different part numbers to confirm this and could possibly help date a winch head.
